Amortization Calculator

Amortization is the gradual reduction of a debt over a given period. Our amortization calculator will amortize (show the reduction) your debt (such as a mortgage) and display your payment breakdown of interest paid, principal paid and loan balance over the life of the loan.

It comes as a surprise to some that most of your initial payments on a loan are used to pay interest. For example, in a 30-year mortgage over 83% of your payments are used to pay down interest in the first year, while only 3% of your payments are used to pay down interest in the final year. This is the primary reason why little equity is built in the first few years of a mortgage.
