Toolkit Feature

See how extra mortgage payments pay off

Even a small increase to your monthly payment can shave years off a mortgage and save thousands in interest. See exactly how much, for your loan.

Small increases, big impact

Because mortgage interest compounds against a shrinking balance, extra payments made earlier in a loan have an outsized effect on total interest paid. The extra payment calculator shows exactly how much time and money a given increase saves.

What you'll see

  • Shortened loan term — how many months or years earlier the loan is paid off.
  • Interest savings — total interest saved over the life of the loan.
  • Updated payoff date — a clear, new timeline based on your extra payment amount.

Pairs well with the mortgage calculator

Start with the mortgage calculator to see your baseline amortization schedule, then use this tool to test how different extra payment amounts change the outcome.

Who it's for

Homeowners looking to pay off their mortgage faster, and buyers deciding between a shorter loan term or extra payments toward a longer one.

Frequently asked questions

How much can extra payments actually save?

It depends on your loan amount, rate, and how much extra you pay, but even modest additional payments can shorten a 30-year loan by several years and save a significant amount in total interest — the calculator shows your exact numbers.

Can I model one-time or recurring extra payments?

The extra payment calculator lets you see how additional payments affect your loan term and total interest, whether you're planning an ongoing increase to your monthly payment or an occasional lump sum.

Does paying extra always make sense?

Not necessarily — it depends on your interest rate compared to other financial priorities. The calculator shows the interest and time savings clearly so you can weigh that against other uses for the money.
