By inserting the necessary inputs, CUMIPMT enables you to gauge the interest accumulations during designated periods with precision. You simply need to furnish details concerning the interest rate, total payment periods, initial loan amount, starting and ending periods for interest assessment, and the payment type — whether payments are due at the beginning or end of each period.

Examples

Let's say you take out a loan of $50,000 with an annual interest rate of 4% over 5 years. You want to calculate the cumulative interest paid between the 3rd and 12th payment. The CUMIPMT formula would be: =CUMIPMT(4%/12, 5*12, 50000, 3, 12, 0) This will return the total interest paid between the 3rd and 12th payment period of the loan.

Imagine you invest $10,000 at an annual interest rate of 6% compounded monthly. You wish to determine the cumulative interest earned between the 8th month and the final maturity at 24 months. The CUMIPMT formula would be: =CUMIPMT(6%/12, 24, -10000, 8, 24, 0) This will yield the cumulative interest earned for the specified investment periods.
