MAPR Calculator for Closed-End Loans with Known Monthly Payment

Use the calculator to determine the Military Annual Percentage Rate (MAPR) for a loan where you already know the monthly payment. MAPR is a standard calculation used by lenders for loans covered by the Department of Defense's Military Lending Act & Regulation Z. It is similar to a standard APR calculation but includes additional fees in the calculation and limits any loan to a MAPR of no more than 36%. MAPR calculations incorporate these fees into a single rate. While MAPR calculations may vary slightly from lender to lender, all lenders must follow the same rules.
