CUMIPMT function

This article describes the formula syntax and usage of the CUMIPMT  function in Microsoft Excel.


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


CUMIPMT(rate, nper, pv, start_period, end_period, type)

The CUMIPMT function syntax has the following arguments:

  • Rate    Required. The interest rate.

  • Nper    Required. The total number of payment periods.

  • Pv    Required. The present value.

  • Start_period    Required. The first period in the calculation. Payment periods are numbered beginning with 1.

  • End_period    Required. The last period in the calculation.

  • Type    Required. 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.

  • 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.


Copy the example data in the following table, and paste it in cell A1 of a new Excel worksheet. For formulas to show results, select them, press F2, and then press Enter. If you need to, you can adjust the column widths to see all the data.




Annual interest rate


Years of the loan


Present value





Total interest paid in the second year of payments, periods 13 through 24



Interest paid in a single payment in the first month



  • Divide the interest rate by 12 to get a monthly rate. Multiply the years the money is paid out by 12 to get the number of payments.

  • In Excel Online, to view the result in its proper format, select the cell, and then on the Home tab, in the Number group, click the arrow next to Number Format, and click General.
