CUMIPMT function

Returns the cumulative interest paid on a loan between start_period and end_period.



Rate     is the interest rate.

Nper     is the total number of payment periods.

Pv     is the present value.

Start_period     is the first period in the calculation. Payment periods are numbered beginning with 1.

End_period     is the last period in the calculation.

Type     is the timing of the payment.



0 (zero)

Payment at the end of the period


Payment at the beginning of the period


  • Make sure that you are consistent about the units you use for specifying rate and nper. If you make monthly payments on a four-year loan at an annual interest rate of 10 percent, use 10%/12 for rate and 4*12 for nper. If you make annual payments on the same loan, use 10% for rate and 4 for nper.

  • Nper, start_period, end_period, and type are truncated to integers.

  • If rate ≤ 0, nper ≤ 0, or pv ≤ 0, CUMIPMT returns the #NUM! error value.

  • If start_period < 1, end_period < 1, or start_period > end_period, CUMIPMT returns the #NUM! error value.

  • If type is any number other than 0 or 1, CUMIPMT returns the #NUM! error value.

Description (Result)


Total interest paid in the second year of payments, periods 13 through 24 (-11135.23)
