Mortgage amortization calculator

Build an amortization schedule and compare 25 vs 30-year amortization: payment, total interest and balance at the end of each term.

Updated October 7, 2026

How is it calculated?

Amortization is how long it takes to repay the mortgage at the current payment; the term is how long your rate and contract last. A longer amortization lowers the payment but raises total interest.

What should I do with the result?

Use it to set a budget or a target rate, then let lenders bid on your actual mortgage. Bids include rate, penalty method, prepayment and fees, so you can compare the full cost.

Frequently asked questions

Can I get a 30-year amortization?
