How to use
The PMT function can be used to figure out the future payments for a loan, assuming constant payments and a constant interest rate. For example, if you are borrowing $10,000 on a 24 month loan with an annual interest rate of 8 percent, PMT can tell you what your monthly payments be and how much principal and interest you are paying each month.
- The payment returned by PMT includes principal and interest but will not include any taxes, reserve payments, or fees.
- Be sure you are consistent with the units you supply for rate and nper. If you make monthly payments on a three-year loan at an annual interest rate of 12 percent, use 12%/12 for rate and 3*12 for nper. For annual payments on the same loan, use 12 percent for rate and 3 for nper.
