Selected Data Record:

A Data Record is a set of calculator entries that are stored in your web browser's Local Storage. If a Data Record is currently selected in the "Data" tab, this line will list the name you gave to that data record. If no data record is selected, or you have no entries stored for this calculator, the line will display "None".

About

About the Free Loan Amortization Calculator

This online Free Loan Amortization Calculator will calculate the unknown variable from three known variables -- for all of the most common payment intervals.

Plus, unlike most other loan amortization calculators, the calculator on this page gives you the option to create and print a free loan amortization schedule.

If you are making a monthly payment and you're not interested in printing out any loan amortization tables, please visit the Missing Term Loan Calculator.

Most Commonly Used to Find the Payoff Amount

If you know any 3 of the 4 loan variables (principal, interest rate, monthly payment and number of payments remaining) this calculator will use TVM (time value of money) calculations to calculate the unknown variable.

The most common use for this calculator is to calculate the current payoff amount of existing loans. After all, you usually know the annual interest rate, the number of payments remaining, and the monthly payment amount. What's not always clear is how much money it will take to pay off a loan this month.

That's because the payoff amount cannot be arrived at by simply multiplying the monthly payment amount by the number of payments remaining, as future payments include interest charges that will not apply if the loan is paid off early.
