# WorksheetFunction.Ispmt (Excel)

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

Make sure that you are consistent about the units that 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.

## Arguments

Arg1, Arg2, ..., Arg4

Arg1 (Double) - Rate - the interest rate for the investment.

Arg2 (Double) - Per - the period for which you want to find the interest; must be between 1 and nper.

Arg3 (Double) - Nper - the total number of payment periods for the investment.

Arg4 (Double) - Pv - the present value of the investment. For a loan, pv is the loan amount.
