ISPMT functionThe ISPMT function calculates the interest paid during a particular period of an investment.

Parts of an ISPMT formula

ISPMT(rate, period, number_of_periods, present_value)

Part
Description
Notes

rate
The interest rate.

period
The time frame for which you want to view the interest payment.
Should be number between 1 and number_of_periods.

number_of_periods
The number of payments to be made.

present_value
The current value of the annuity.

Sample formula

ISPMT(15%, 2, 5, 1000)

Notes

Make sure that consistent units are used for the rate, period, and number of periods. For example, a car loan for 36 months may be paid monthly, in which case the annual percentage rate (APR) should be divided by 12 and the number of payments is 36. A different type of loan of the same length might be paid quarterly, in which case the APR should be divided by 4 and the number of payments would be 12.
