We can use the excel CUMIPMT function to return the cumulative interest to be paid on a loan from a start to an end period. This function is useful for calculating and verifying the total interest paid between any two payment periods. The steps below will walk through the process.
Figure 1 – How to Use the Excel CUMIPMT Function
=CUMIPMT(rate, nper, pv, start_period, end_period, type)
- Rate– This is the interest rate per period (C6/12)
- Nper– This is the total number of payments for the loan. (C9)
- Pv– This is the present value or the total value of all payments at present (C5)
- Start_period– This represents the first payment in a calculation.
- End_period– This represents the last payment in a calculation.
- Type– When the payments are due. 0 = payment due at the end of a period. 1 = payment due at the beginning of a period.
Setting up the Data
We will set up our table as shown in figure 2. We intend to calculate the cumulative interest paid on the loan amount for 60 months.
- We will place the parameters in the range: B5:B9.
- The figures will be contained in Column C
- The result will be returned in Cell C10
