This calculator is designed primarily for fixed-rate, fully amortizing mortgages. Results for other mortgage structures may differ. Estimates are for educational purposes only and are not financial advice.

A downloadable month-by-month payoff plan with lump-sum and target-date strategies is in development.
What Is a Mortgage-Free Date?
Your mortgage-free date is the date on which your scheduled mortgage balance reaches zero under the assumptions you enter — your current balance, your interest rate, your remaining term, your monthly principal and interest payment, and any extra payments you plan to make. Change any of those assumptions and the date moves.
How Does a Mortgage Payoff Calculator Work?
A payoff calculator amortizes your loan. Each month, interest is charged on the outstanding mortgage balance at one twelfth of the annual interest rate. Whatever is left of your monthly payment after that interest reduces the principal. Any additional principal payment reduces the balance further. Repeat until the balance is zero, and the number of months is your remaining term.
The fixed-rate mortgage payment formula
M = P × [ r(1+r)ⁿ / ((1+r)ⁿ − 1) ]
- M
- — the scheduled monthly principal and interest payment
- P
- — the principal, i.e. the amount currently owed
- r
- — the monthly interest rate (annual rate ÷ 12)
- n
- — the number of monthly payments remaining
This formula applies to fixed-rate, fully amortizing mortgages. Interest-only, balloon, adjustable-rate and some non-US products compound or reset differently and are not modeled here.
How Much Can Extra Mortgage Payments Save?
Every extra dollar applied to principal permanently removes the interest that dollar would have generated for the rest of the loan. Because the effect compounds, small consistent overpayments matter more than their size suggests.
Worked example
A $300,000 balance at 6.5% with 24 years and 6 months remaining carries a scheduled principal and interest payment of roughly $2,030 a month. Paying an extra $250 each month retires the balance around three and a half years earlier and cuts tens of thousands of dollars of interest. Enter your own numbers above — the comparison table shows both schedules side by side.
How Much Faster Can I Pay Off My Mortgage?
There is no single answer, because the result depends on your outstanding balance, your interest rate, your remaining term, your regular payment, how much extra you add each month, and when any lump-sum payments land. A lump sum made early in the loan removes far more future interest than the same amount paid near the end.
Mortgage Payoff vs. Mortgage-Free Date
The two terms describe the same event from different angles. “Mortgage payoff” usually refers to the act of clearing the debt and the payoff amount your lender quotes. Your “mortgage-free date” is the calendar date that event is projected to happen. A payoff calculator and a mortgage-free date calculator run the same amortization; one reports an amount, the other reports a date.
Important Things to Check Before Paying Off Your Mortgage Early
- Prepayment penalties. Some mortgages charge a fee for overpaying, or cap annual overpayments. Check your mortgage documents.
- How extra payments are applied. Tell your lender that extra amounts should reduce principal. Otherwise they may be held as a prepaid future installment, which does not shorten the term.
- Opportunity cost. Cash used to pay down a mortgage is not available for other debts, investments or goals.
- Tax treatment. Mortgage interest deductions and reliefs vary by country and by year.
- Emergency fund. Home equity is not liquid. Most guidance suggests keeping accessible savings before overpaying.
These are general considerations, not personalized financial advice.
Frequently Asked Questions
How do I calculate my mortgage-free date?
Enter your current balance, interest rate and remaining term. The calculator amortizes the loan month by month — interest first, then principal — and reports the month in which the balance reaches zero. That month, projected forward from today, is your mortgage-free date.
Does paying extra on my mortgage save interest?
Yes, when the extra amount is applied to principal. Interest each month is charged on the outstanding balance, so a smaller balance means less interest accrues every month that follows.
How much faster will I pay off my mortgage if I pay an extra $100 a month?
It depends on your balance, rate and remaining term. On a $300,000 balance at 6.5% with 24 years and 6 months left, an extra $100 a month shortens the term by roughly a year and a half. Use the what-if buttons to see your own figure.
How much interest can I save by paying extra?
The calculator shows the difference between total interest on your scheduled payments and total interest with extra payments applied. Savings grow with a higher rate, a longer remaining term and a larger extra payment.
Does this calculator include property taxes and homeowners insurance?
No. It models principal and interest only. Escrow items such as property taxes, homeowners insurance and HOA fees are real costs, but they do not change how your loan principal amortizes.
Can I use this calculator for a 15-year mortgage?
Yes. Enter the remaining term as 15 years, or whatever portion of it is left.
Can I use it for a 30-year mortgage?
Yes. Any fully amortizing fixed-rate term works, including 30, 25, 20 and 10 years.
Can I make a one-time lump-sum payment?
Yes. Enter the amount in the one-time extra payment field and choose the month it is applied. The lump sum reduces principal in that month and the remaining schedule is recalculated.
What happens if I make biweekly payments?
Paying half your monthly amount every two weeks produces 26 half-payments — 13 monthly payments' worth — each year. The option models that as an extra one-twelfth of a payment each month. Confirm with your lender how biweekly payments are actually applied.
Can I use the calculator outside the United States?
Yes. Amortization math is currency-independent, and you can display results in USD, AED, AUD, CAD, CHF, CNY, EUR, GBP, INR, JPY, MYR or SGD. The currency setting changes the display only — no conversion is applied. Some markets, notably Canada and the UK, use different compounding or fixed-rate periods, so treat the result as an estimate.
Does the calculator work for adjustable-rate mortgages?
Not reliably. It assumes a single fixed rate for the whole remaining term. With an adjustable-rate mortgage the result is only valid for as long as your current rate holds.
Should I pay off my mortgage early?
That depends on your rate, your other debts, your savings and your tax situation, and this page cannot advise you. Weigh the guaranteed interest saved against keeping cash available, and check your mortgage documents for prepayment rules.
