This template enables users to calculate, analyze and forecast the monthly loan balances and interest charges relating to any loan that is subject to monthly repayment and daily interest calculations. The template was specifically designed for home loan calculations but can be used for any loan where the principles of monthly repayment and daily interest are applied.
The main purpose of this template is to calculate loan balances and interest amounts based on the same calculation methodology that is applied by most financial institutions. This template can therefore be used to recalculate the amounts on the loan account statements that are received from financial institutions. The template accommodates multiple interest rate changes (variable interest rates), increased instalments and ad hoc loan repayments. In addition, the template also includes comprehensive forecast features which provide users with the functionality to analyze any loan over the entire loan period.
Note: Refer to our Loan Statement template for a simplified version of this template. The Loan Statement template only includes the statement and summary features of this template and is therefore a lot simpler to understand and use. If you are only interested in loan amortization calculations, we recommend that you download our free Loan Amortization template.
Worksheet Summary
The main purpose of each worksheet is as follows:
TransCode - includes the default transaction types that need to be selected when entering loan account transactions. Additional transaction types can also be added to the default list of transactions codes.
Statement - all loan account transactions should be recorded on this sheet. All the interest and loan account balance calculations in this template are based on the transactions that are recorded on this sheet. Note that the Statement sheet includes 12 columns but only four of these columns require user input (the columns with the yellow column headings).
Summary - includes a monthly summary of loan account transactions that is calculated from the Statement sheet. No user input is required on this sheet.
Review - includes a comprehensive analysis of loan account balances and interest charges over the entire loan period. Loan account transaction totals are compared to an initial loan amortization calculation and a forecast of the remaining loan repayment period is added to the transaction totals and then also compared to the initial loan amortization schedule. The loan repayment forecast is based on a standard amortization calculation that is applied to the outstanding loan balance on a user defined review date as well as a loan amortization forecast that accommodates ad hoc loan repayments. This sheet can be used to calculate the outstanding loan balance and cumulative interest charges at the end of any month that falls within the loan period. User input is limited to selecting the appropriate loan review date.
InitialAmort - includes an initial loan amortization calculation that is based on the principle loan amount, interest rate, loan period and repayment commencement date that is specified in cells D3 to D6. All the calculations on this sheet are automated.
ForecastPmt - all forecasted ad hoc loan repayments should be recorded on this sheet. The monthly periods in the first column are based on the monthly periods on the Summary sheet. The ad hoc loan repayments that are recorded on this sheet are included on the ForecastAmort sheet.
ForecastAmort - includes two amortization tables that relate to the remaining loan repayment period. The first table includes a column for ad hoc loan repayments (based on the amounts entered on the ForecastPmt sheet) and the second table is based on standard loan amortization principles. Both tables are compiled based on the user defined loan review date that is selected on the Review sheet.
CalcAmort - includes a loan amortization table calculator. This sheet is not linked to any of the other sheets in the template and has been included to enable users to compile their own loan amortization calculations.
Note: The template includes a lot of complex formulas and has been designed within a specific worksheet structure. We therefore do not recommend adding additional rows or columns within the existing worksheet framework because it may result in errors or inaccurate calculations being encountered. If you therefore want to add your own calculations to the template, we recommend inserting a new worksheet for this purpose.
Template Set-up
Aside from recording loan account transactions, the template does not require a lot of set-up. We recommend that you start by entering the initial loan terms as per the loan agreement on the InitialAmort sheet. This includes the loan principle amount, interest rate, loan period and repayment commencement date. These input cells have no effect on your loan statement calculations and are only used to specify the required variables for calculating the initial amortization table on the InitialAmort sheet. The calculation results are included on the Review sheet in order to compare actual loan account movements to the initial loan amortization table.
The next step is to review the transaction types on the TransCode sheet. The default template includes 7 transaction types of which the first 5 should be left unchanged. Each of these transaction types has a specific purpose and if you therefore change the type of transaction that is associated with the default transaction code, you may encounter inconsistencies in the template calculations.
The Admin Fee and Insurance Premium transaction codes have been added as separate transaction types because these costs are frequently included as separate line items on home loan account statements and usually form part of the monthly loan repayment amounts. If you do not require these items, you can delete them or replace them with other costs that are included on your loan account statement. Note that both transaction type number 6 and 7 are reported separately on the Statement and Summary sheets and if you change the default transaction type descriptions, the new descriptions will be included in column C on the Statement sheet but you have to enter the new descriptions in columns G and H on the Summary sheet.
All the transaction types on the TransCode sheet are included in list boxes in column B on the Statement sheet. Additional transaction types that are added to the default list of transaction types are also available for selection from these list boxes. You will therefore be able to enter the transactions relating to these transaction types on the Statement sheet but note that all transaction types with transaction codes greater than or equal to 8 are grouped together in one column on the Summary sheet (column I).
Note: The contents on the TransCode sheet have been included in an Excel table. A new transaction code can therefore be created by simply entering the new code in the first empty cell below the table in column A. The table will then be extended automatically to include the new transaction type.
Loan Account Transactions
All loan account transactions need to be recorded on the Statement sheet. This sheet includes 12 columns but only four of these columns require user input (columns with a yellow column heading). The contents of this sheet have been included in an Excel table which means that the columns with light blue column headings (containing formulas) will automatically be copied for all new transactions that are recorded.
When you therefore record any transaction, you will need to enter a date (in column A), select a transaction type from the list box in column B, enter a new interest rate (only if an interest rate change transaction is being recorded, otherwise enter 0%), enter a transaction amount in column E and the formulas in all the other columns will automatically be copied from one of the existing rows in the Excel table.
Note: New transactions can be recorded by simply entering a transaction date in the first blank cell below the Excel table in column A. The table will then automatically be extended to include the new transaction and all the formulas in the columns with a light blue column heading will automatically be copied into the new transaction row.
The following important guidelines should be followed when recording transactions on the Statement sheet:
- The first transaction that is recorded on this sheet should always be an interest rate change transaction (transaction type 5) and this transaction should be recorded on the same date as the first transaction on your loan account statement. The interest rate that is applicable to the loan should be entered in column D and the transaction amount in column E should be nil (the transaction amount for all interest rate change transactions should always be nil). This entry establishes the interest rate that should be used to calculate interest from the beginning of the loan period.
- All the transactions that are recorded on the Statement sheet should form part of a continuous cell range. There should therefore be no empty rows between transactions, otherwise the loan account balances and therefore also the interest calculations will be inaccurate.
- All transactions should be recorded or sorted in an ascending date sequence (oldest transactions first). You'll notice that if you enter a transaction that is out of sequence, the transaction date will be highlighted in red. This error can be corrected by simply sorting all the transactions on the Statement sheet in an ascending order by the date in the first column. By sorting the transactions in the correct order, you will ensure that the date sequence is rectified and that all interest calculations are accurate.
- The monthly interest on the outstanding loan account should be capitalized on the last day of each month. In order to accomplish this, simply record an interest capitalization transaction (select transaction code 4) for the last day of each month. The transaction amount in column E should be nil because the monthly interest capitalization calculation is performed automatically through the formula that has been entered in column F. This interest calculation only applies to transaction type 4 - if you therefore specify the incorrect transaction type, no interest will be capitalized to the loan at the end of the appropriate month. Also note that the date that is entered should be the last day of the month - if you enter any other date, the interest calculation will not be accurate. The transaction date in column A will be highlighted in orange if the incorrect interest capitalization date is specified.
- It is imperative that you don't replace any of the formulas in the columns with light blue column headings with alternative values because it will result in inaccurate calculations. We recommend that you save the template under a default file name after downloading it and save each loan calculation under a different file name. You will then be able to revert back to the original template if you delete any of the formulas by accident.
- All transaction amounts except for loan repayments and ad hoc repayments should be entered as positive values. Loan repayments and ad hoc repayments should be entered as negative values - if you enter positive values for any repayment type transactions, the transaction amounts will be highlighted in orange.
The following section covers the default transaction types that should be recorded on the Statement sheet:
Loan Advances
Loan advances are amounts that are received from the financial institution who grants the loan. You can record as many loan advances as required by simply entering the appropriate transaction date, selecting transaction type 1 and entering the appropriate loan advance amount in the Transaction Amount column (column E). Loan advances should be entered as positive amounts.
Loan Repayments
For the purpose of compiling an accurate loan forecast, we have assigned scheduled loan repayments and ad hoc loan repayments to different transaction types. Scheduled loan repayments are determined by the terms in a loan agreement, while ad hoc loan repayments are effected at the borrower's own discretion. It is important to allocate repayments to the correct repayment type because the scheduled loan repayments that are recorded on the Statement sheet form part of the calculation of the remaining loan repayments which is important for forecasting purposes.
Note: The number of remaining loan repayments is used to compile a loan forecast amortization table. If you therefore allocate ad hoc repayments to the loan repayment transaction type (transaction type 2), the forecast will not be accurate. Also note that a scheduled loan repayment should be entered for all monthly periods where a loan repayment is due, regardless of whether a loan repayment has been effected or not. In some instances (for example building loans), the loan period may commence before scheduled loan repayments are deducted on the loan account. When scheduled loan repayments are then deducted at a later stage, the repayment amount is calculated over a shorter loan period. In order to facilitate this calculation, you therefore need to include the correct remaining loan repayments in the calculation - this can be achieved by recording all scheduled loan repayments on the Statement sheet and simply entering a nil amount if a loan repayment is due but has not been effected during any particular repayment period.
Scheduled loan repayments need to be recorded on the Statement sheet by entering the appropriate transaction date, selecting transaction type 2 and entering the appropriate loan repayment amount as a negative value in the Transaction Amount column. Note that if you enter a positive loan repayment amount, the amount will be highlighted in orange in the Transaction Amount column until it is rectified.
Ad Hoc Repayments
The template accommodates an unlimited number of ad hoc loan repayments. It also makes no difference whether the ad hoc repayment is an increased instalment or a lump sum repayment.
Ad hoc repayments can be recorded on the Statement sheet by simply entering the appropriate transaction date, selecting transaction type 3 and entering a negative amount in the Transaction Amount column. If you enter a positive ad hoc loan repayment amount, the amount will be highlighted in orange until the error is rectified.
Interest Capitalization
The interest calculations in this template are based on the daily loan account balances. Transactions are included in the daily loan account balance as if the transactions occurred at the beginning of the day. For example, if a loan repayment is dated on the 2nd of January, the repayment is deducted from the loan balance of the previous day and included in the interest calculation from the 2nd of January. For month end interest capitalization purposes, the loan repayment on the 2nd will therefore be included in the monthly interest calculation for a period of 30 days.
All interest calculations are automatically performed based on the transactions that are recorded on the Statement sheet. As we've mentioned before, it is imperative that all transactions are recorded in the correct date sequence (ascending date order), otherwise the interest calculations may not be accurate. All interest calculations are performed based on the balances calculated in the Transaction Closing Balance column by applying the appropriate interest rate and the number of days that the balance is in effect to this amount.
The calculated interest is capitalized to the loan account balance when you enter an Interest Capitalization transaction for the last day of the appropriate calendar month. Note that if you don't enter this transaction, the interest calculated for the particular month will not be added to the loan account balance and your loan account statement will not be accurate! It is therefore imperative that you add an Interest Capitalization transaction to the Statement sheet for every month that forms part of the loan period.
Also note that this transaction has to be dated on the last day of the month - if you use any other date, the interest calculation will not be accurate. We have implemented conditional formatting in column A to highlight the interest capitalization transactions that are not dated on a month end date in orange. When you change the transaction date to the appropriate month end date, the formatting is automatically removed.
Interest capitalization transactions can be recorded by entering the appropriate month end date, selecting transaction type 4 and entering a nil amount in the Transaction Amount column. The calculated interest is reflected in column F and is automatically added to the outstanding loan balance in column G.
Interest Rate Changes
This template accommodates an unlimited number of interest rate changes. An interest rate change can be recorded on the Statement sheet by simply entering the effective date of the interest rate change in column A, selecting transaction type 5, entering the appropriate new interest rate in column D and entering a nil amount in the Transaction Amount column. You'll notice that the interest rate in column H (used in all interest calculations) will change to the new interest rate that has been recorded. Interest on all subsequent transactions will be calculated based on the new interest rate (until the next interest rate change transaction is recorded).
As we've mentioned before, the first transaction that should be recorded on the Statement sheet is an interest rate change transaction. This transaction establishes the interest rate that should be used to calculate interest from the beginning of the loan period. If you omit this transaction, the interest rate that will be used to calculate interest on the initial loan balance will be nil and no interest will therefore be calculated and capitalized to the initial loan account balance until an interest rate is defined.
Interest rate changes can only be recorded by using transaction type 5 - if you enter a new interest rate in column D and select any other transaction type, the interest rate change will not have any effect on interest calculations.
Other Loan Costs
As we've mentioned before, other loan costs (like admin fees and insurance) can be recorded by using transaction codes 6 and 7 or adding the appropriate transaction codes to the TransCode sheet and selecting the appropriate transaction type from the list box in column B on the Statement sheet. These transactions usually relate to costs that are charged to the loan account and should therefore be entered as positive values in the Transaction Amount column. Financial institutions typically include these costs in scheduled loan repayments and the costs are therefore deducted from the loan account balance when you record scheduled loan repayments (transaction type 2) on the Statement sheet.
Loan Account Statement
All loan transactions should be entered on the Statement sheet in accordance with the guidance provided in the previous section. After reading through the previous section, you should therefore be able to record all the appropriate transactions on the Statement sheet and we'll now provide guidance on the calculated columns (columns with a light blue column heading) on this sheet.
The transaction description in column C has been included on the Statement sheet so that it is easy to identify the transaction types that are selected from the list boxes in column B. The list boxes only include the transaction type numbers - we've therefore included the description in column C to enable users to review the transaction type that has been selected.
The calculated interest in column F represents the amount of interest that is capitalized to the loan account at the end of every calendar month. All scheduled loan repayments consist of an interest and capital portion - this column includes the interest portion that is calculated based on the daily loan account balances during the particular monthly period. This column should therefore only contain one calculated interest amount per calendar month.
The monthly interest amount that should be capitalized is the total of all the accrued interest amounts in column L for the particular month. The accrued interest is calculated from the interest rate in column H, the interest days in column J and the transaction closing loan balance in column K.
The outstanding loan balance on each transaction date is calculated in column G. This amount represents the capital balance that is still outstanding on the loan.
The monthly capital portion of the loan repayments can be calculated by adding the interest and other costs together and deducting the sum of the scheduled loan repayments and the ad hoc loan repayments from this amount. Note that it may therefore be easier to calculate this amount from the totals on the Summary sheet.
Loan Account Summary
The Summary sheet includes a complete breakdown of the movements on the loan account for all monthly periods. All the totals on this sheet are calculated from the transactions that are entered on the Statement sheet. No user input is required on this sheet - users are only required to extend the Excel table for the appropriate number of new rows in order to add the required number of monthly periods to the summary.
Note: The contents of this sheet have been included in an Excel table. The table can be extended by clicking the arrow in the bottom right corner of the table and dragging the table border downwards for the required number of rows. All the formulas that are included in the table will be copied automatically.
The first monthly period on the Summary sheet is determined by the transaction date of the first transaction on the Statement sheet. The transaction date in row 4 on the Statement sheet therefore determines which monthly period is displayed in the first row of the Summary sheet. All subsequent monthly periods on the Summary sheet are calculated based on the first monthly period.
The Loan Advance column is calculated based on all the transactions with a transaction type of 1 on the Statement sheet. Scheduled loan repayments (transaction type 2), ad hoc repayments (transaction type 3), interest capitalized (transaction type 4), admin fees (transaction type 6), insurance premiums (transaction type 7) and other costs (all transaction types greater than 7 that have been added to the TransCode sheet) are also calculated based on the transaction types of the transactions that are recorded on the Statement sheet.
The number of repayments in column K is calculated by counting the number of scheduled loan repayments (transaction type 2) on the Statement sheet. This number should agree to the loan period that has elapsed at any given point in time - if the number is not correct, you should add the appropriate scheduled loan repayment on the Statement sheet (use a nil amount if no actual repayment has been effected). The number of repayments also forms part of the remaining loan period calculation for forecasting purposes (refer to the Loan Review section).
As we've mentioned before, an interest capitalization transaction should be recorded for the month end date of every monthly period that forms part of the loan period in order to calculate interest accurately. If this transaction has been omitted for any monthly period, the number of repayments calculation in column K on the Summary sheet will contain an error ("month end?") that will be highlighted in orange. This error can be corrected by simply entering an interest capitalization transaction (transaction type 4) for the particular month on the Statement sheet.
Note: The number of repayments on the Summary sheet should increase in increments of 1 for every subsequent monthly period. If this is not the case (two monthly periods reflect the same number), it means that a scheduled loan repayment (transaction type 2) has not been entered for the particular month (the second month with the same number of repayments). This problem can be rectified by simply entering a scheduled loan repayment amount (use any date during the particular monthly period) on the Statement sheet. A nil amount can be recorded if an actual loan repayment has not been effected during the month.
The Summary sheet can be used to analyze all loan account transactions on a monthly basis for the duration of the loan period. It is therefore an extremely useful tool for reviewing the loan account transaction and balance history.
The monthly periods that are included on the Summary sheet also determine which periods are available for selection on the Review sheet. It is therefore important to keep the Summary sheet up to date based on the transactions that have been recorded on the Statement sheet. As we've mentioned before, users simply need to extend the Excel table in order to copy all the formulas on the Summary sheet downwards so that the appropriate number of monthly periods are included on the sheet.
Loan Review
The Review sheet enables users to compile a comprehensive loan analysis for the entire loan period. The transactions that are recorded on the Statement sheet are compared to an initial loan amortization table before a forecast that is based on the remaining loan repayment period is added to the actual transactions that have been recorded on the Statement sheet in order to compile a loan analysis that covers the entire loan period. The actual loan forecast is then also compared to the initial amortization forecast and is calculated on two forecast bases - a standard amortization basis and an ad hoc repayments basis (refer to the Loan Repayment Forecasts section for more guidance on the forecast features).
The only user input that is required on the Review sheet is selecting the appropriate loan review date. The loan review date input cell (cell B3) contains a list box that includes all the monthly periods on the Summary sheet. You can review the actual and initial loan amortization balances based on any monthly period that is selected from the list box. All the calculations on the Review sheet are automatically updated based on the review date that is selected. If a monthly period is not included in the list box, it means that you have not added the appropriate period to the Summary sheet.
The loan history calculations include all the transactions that are recorded on the Statement sheet and are dated before the loan review date that is selected. The initial amortization column also only includes amounts before the review date. The loan history calculation therefore facilitates a comparison of the initial loan terms and the actual loan account movements up to the review date.
The remaining loan repayments section includes three calculations - an initial loan amortization, a forecast calculation that is based on a standard amortization table and a forecast calculation that is based on an amortization table that incorporates ad hoc loan repayments. Refer to the Initial Loan Amortization and Loan Repayment Forecasts sections for more guidance on these calculations.
The forecast calculations for the remaining loan repayment period are based on the number of remaining loan repayments (cell B7) which is calculated by deducting the number of actual loan repayments in cell B6 from the loan period in cell B5. The number of actual loan repayments is determined by the number of scheduled loan repayment transactions that have been recorded on the Statement sheet - it is therefore imperative that a scheduled loan repayment (transaction type 2) is recorded on the Statement sheet for every month during the loan period, even if no actual loan repayment has been effected (use a nil value under these circumstances).
The loan period summary section calculates the total interest and capital repayment balances over the entire loan period for all three calculation bases. This section also includes a comparison between the interest charges of the initial loan amortization calculation and the standard forecast amortization calculation as well as a comparison between the interest charges of the standard forecast amortization and the ad hoc forecast amortization calculations.
An effective annual interest rate over the entire loan period is also calculated for all three calculation bases. You'll probably notice that the effective interest rate for the ad hoc forecast is in most instances significantly lower than the interest rates that were entered on the Statement sheet and included on the ForecastAmort sheet - this is because the effective interest rate is calculated over the entire loan period and ad hoc repayments result in a loan being repaid over a shorter loan period. It therefore does not mean that a lower interest rate is achieved by effecting ad hoc repayments, but simply represents the interest savings that result from a shorter repayment period. The effective interest calculation result should therefore be interpreted in this context.
Initial Loan Amortization
An initial loan amortization calculation has been added to the template in order to facilitate a comparison between actual loan balances and the initial loan repayment terms. This comparison is especially useful for measuring the effect of interest rate changes. The initial loan amortization table is included on the InitialAmort sheet.
This amortization table is calculated based on the initial loan amortization input values that are specified at the top of the sheet. Note that the loan period is limited to 360 months (30 years) and the monthly periods are determined based on the repayment commencement date that is specified in cell D6.
The loan principle amount (cell D3) should be the same as the total of all the loan advances that have been recorded on the Statement sheet (refer to the Summary sheet in order to calculate the total of all actual loan advances). Note that if there is a difference, the loan principle amount will be highlighted in orange. The interest rate and loan period per the initial loan agreement should be entered in cells D4 and D5 respectively.
In most instances, the repayment commencement date (cell D6) will be the same as the first transaction date that is entered on the Statement sheet. However, the repayment of some loans (like building loans) only commence on a later date and by including this input cell, we're therefore able to base the periods that are included in the initial amortization table on a user defined date so that the initial amortization calculation will match the commencement of actual loan repayments.
Loan Repayment Forecasts
The template also includes two separate loan repayment forecasts that are used to calculate loan balances and interest charges for the remaining loan repayment period. Note that the remaining loan repayment period is calculated based on the loan review date that is selected on the Review sheet (cell B3). The period that is selected from this list box therefore determines which repayment periods are based on actual transactions (all the periods before the loan review date) and which repayment periods are based on the forecasts (all the periods after the loan review date). The loan repayment forecasts are added to the actual loan account transactions in order to compile a loan review for the entire loan period. The forecasts consist of a standard loan repayment amortization table and an ad hoc loan repayment amortization table. Both amortization tables are included on the ForecastAmort sheet.
Both amortization tables are based on the calculated values that are displayed at the top of the ForecastAmort sheet. The review date is selected from a list box on the Review sheet and the outstanding loan balance and interest rate is determined by looking up the appropriate values on the Statement sheet based on the loan review date that has been selected.
The number of remaining loan repayments is calculated on the Review sheet by subtracting the number of actual loan repayments from the initial loan period. The number of actual loan repayments is calculated by counting the transaction type 2 transactions on the Statement sheet that are dated before the loan review date. The initial loan period is specified on the InitialAmort sheet.
The standard amortization table (column K to P) calculates the remaining monthly loan repayment amounts and the interest that will be incurred over the remaining loan period. The total interest and capital repayments that are calculated are included on the Review sheet in the "Actual Loan: Standard" column and compared to the initial loan amortization table.
The ad hoc forecast amortization table (column A to I) also calculates the remaining loan repayments and interest but enables users to include ad hoc loan repayments in the calculation. These ad hoc loan repayments should be recorded on the ForecastPmt sheet and are automatically included in the appropriate monthly periods on the amortization table. Note that the monthly periods on the ForecastPmt sheet are determined by the monthly periods on the Summary sheet and extended to include 360 months. You'll also notice that the loan review date that is specified on the Review sheet is highlighted in orange in column A on the ForecastPmt sheet.
Ad hoc loan repayments that are dated before the review date (on the ForecastPmt sheet) will not form part of the ad hoc forecast amortization table (on the ForecastAmort sheet) because the amortization table starts in the month following the review date. If an ad hoc loan repayment is dated before the loan review date, it should however be included in the transactions that are recorded on the Statement sheet if the payment has been effected and it will therefore already be taken into account in the loan analysis of the entire loan period.
The ad hoc amortization table accepts both lump sum repayments and increased instalments and enables users to calculate the interest savings that result from effecting these types of repayments over the remaining loan repayment period. Note that the monthly loan repayment amounts that are calculated on the ad hoc amortization table are not adjusted to take the effect of ad hoc loan repayments into account - the ad hoc loan repayments are allocated directly against the outstanding capital balance of the loan, thereby resulting in a shorter loan repayment period and a significant saving in interest.
The ad hoc forecast amortization table is therefore a comprehensive, flexible loan repayment analysis tool that can be used to analyze the effect of ad hoc loan repayments on interest charges. The interest saving is calculated by comparing the ad hoc forecast amortization table (the "Actual Loan: Forecast" column) to the standard forecast amortization table (the "Actual Loan: Standard" column) on the Review sheet. As we've mentioned before, both of these amortization tables are calculated based on the remaining loan repayment period.
Loan Amortization Table Calculations
The loan amortization calculator on the CalcAmort sheet can be used to perform your own loan repayment and interest calculations by simply specifying the appropriate input values in the cells with a yellow cell background at the top of the sheet.
This calculator can be used to perform any loan repayment calculation over a maximum loan period of 30 years. For example, if you want to determine the new monthly loan repayment amount after a change in the annual loan interest rate:
- Enter an interest rate change transaction on the Statement sheet (in accordance with the guidance that we provided in the Loan Account Transactions section).
- Calculate the outstanding loan balance on the effective date by adding the accrued interest amounts for the particular month (in column L) on the Statement sheet to the outstanding loan balance in column G.
- Enter the outstanding loan balance and the new interest rate in the appropriate input cells on the CalcAmort sheet.
- Enter the remaining loan period in the appropriate input cell on the same sheet.
- The new loan repayment amount is calculated in column D on the CalcAmort sheet.
Add any other monthly loan costs (for example admin fees and insurance premiums) to this amount. The calculated monthly loan repayment amount should equal the amended loan repayment amount that is deducted on the next account statement that is received from the appropriate financial institution.
