About Mortgage Amortization

An amortization schedule shows how your loan balance decreases over time as you make payments. Each payment consists of both principal and interest.

Making extra payments can significantly reduce the length of your loan and save you thousands in interest payments. Even small additional monthly payments can make a big difference over time.

This calculator helps you see exactly how much time and money you can save by making extra payments toward your mortgage principal.
