APR Calculator
The real APR (Annual Percentage Rate) of your mortgage depends a lot on the life expectancy of the loan itself. If you are not planning to let the mortgage run to its official term, it is highly recommended to recalculate the APRs of all the offers you are considering using the most likely real period of time.
Unlike the Interest Rate, the APR does not get locked, leaving the borrower quite vulnerable to the lender’s whim to change closing costs and origination fees at the very last moment. If it happened to you, you can at least see what APR it turns into.
