ISPMT function

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

Description

Calculates the interest paid during a specific period of an investment. This function is provided for compatibility with Lotus 1-2-3.

Syntax

ISPMT(rate, per, nper, pv)

The ISPMT function syntax has the following arguments:

  • Rate    Required. The interest rate for the investment.

  • Per    Required. The period for which you want to find the interest, and must be between 1 and nper.

  • Nper    Required. The total number of payment periods for the investment.

  • Pv    Required. The present value of the investment. For a loan, pv is the loan amount.

Remarks

  • 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 12 percent, use 12%/12 for rate and 4*12 for nper. If you make annual payments on the same loan, use 12% for rate and 4 for nper.

  • For all the arguments, the cash you pay out, such as deposits to savings or other withdrawals, is represented by negative numbers; the cash you receive, such as dividend checks and other deposits, is represented by positive numbers.

  • For additional information about financial functions, see the PV function.
