Description
rate
Required

Return Value

Numeric.

Example

The following expression returns -2111.64 as the monthly payment amount of a loan:
PMT( 0.01, 10, 20000 )

Notes

To calculate interest rate earned in each period, divide the annual rate by the number of payments made in a year. For example, if you make monthly payments at an annual interest rate of 15%, the rate is 15%/12. If you make annual payments, the rate is 15%.
The payment value is negative because these are amounts that you pay.
