Extra Payment Mortgage Calculator

Quick answer: Extra principal can reduce future interest and shorten the payoff timeline, but confirm prepayment terms and cash-flow priorities before sending more than required.

Model a realistic strategy

Try a small monthly amount, a yearly lump sum and a pause during high-expense months. Keep an emergency reserve and compare the guaranteed interest savings with other high-interest debt.

Extra Payment FAQs

How much can an extra mortgage payment save?

The savings depend on balance, rate, remaining term and the timing of each extra principal payment. Use the amortization and extra-payment tabs with your statement figures.

Should extra payments be applied to principal?

Ask your servicer to apply additional funds to principal and confirm the transaction posted correctly. A payment marked as “paid ahead” may not reduce principal as expected.

Can I make one extra mortgage payment each year?

One additional principal-and-interest payment per year can shorten a long loan, but the exact result varies. Compare the annual lump sum with a monthly extra amount in the calculator.
