    Paying off your mortgage early can save tens of thousands in interest and give you financial freedom years ahead of schedule. Even small extra payments made consistently add up to significant time and money saved. This calculator shows exactly how much sooner you will be debt-free and how much interest you will avoid.

    How Extra Payments Reduce Your Mortgage

    Every extra dollar you pay toward principal reduces the balance on which future interest is calculated. Early in the loan this is especially powerful because most of your regular payment goes to interest. An extra $200/month on a 30-year mortgage can often cut 5-7 years off the term.

    Monthly Interest = Remaining Balance × (Annual Rate / 12) Principal Paid = Monthly Payment - Monthly Interest

    Extra payments go entirely to principal, accelerating the payoff timeline significantly.

    Extra Payment Strategies

    There are several ways to pay extra. You can add a fixed amount to each monthly payment, make one extra full payment per year (equivalent to biweekly payments), apply windfalls like tax refunds or bonuses directly to principal, or refinance to a shorter term with a higher required payment.

    Frequently Asked Questions

    Is it better to pay off a mortgage early or invest?

    It depends on your mortgage rate versus expected investment returns. If your rate is 3% and you expect 7% stock returns, investing likely wins mathematically. If your rate is 7%, paying down the mortgage is a guaranteed return equal to that rate. Also factor in tax deductibility of mortgage interest and your personal risk tolerance.

    How do I make sure extra payments go to principal?

    When making extra payments, specify that the extra amount should be applied to principal. Some lenders apply extra payments to the next month's payment instead of reducing principal. Check your loan servicer's instructions and confirm on your statement that the principal balance decreased as expected.

    Does paying off a mortgage early hurt your credit?

    Closing a mortgage account can slightly lower your credit score by reducing your mix of credit types and average account age. However, the financial freedom of being debt-free outweighs this minor, temporary impact for most people.

    What is a biweekly mortgage payment?

    Instead of 12 monthly payments, you make 26 half-payments per year. Because 26 half-payments equal 13 full payments, you effectively make one extra payment per year with no big lump sum. Many lenders offer biweekly programs, or you can do it manually by adding 1/12 of a payment to each monthly payment.
