ISPMT function
The 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.
