Read the guideHow to use a mortgage payoff calculator
A mortgage payoff calculator helps you work backward from a goal: how much would you need to pay each month to clear your remaining mortgage balance within a chosen number of years? Compare that amount with your scheduled principal-and-interest payment to estimate the additional monthly commitment and the difference in remaining interest.
Start with your remaining balance and term
Enter the principal you still owe, your current annual interest rate, and the years remaining on the loan. Use the remaining term rather than the original term. Then enter your target payoff timeline. A shorter target generally requires a higher payment but reduces the time that interest accrues on the balance.
This tool assumes a constant rate and regular monthly payments. Its “Current scheduled P&I” figure is calculated from your inputs; it is not read from your mortgage statement. Check that it matches your actual principal-and-interest payment before relying on the comparison. Escrow payments for property taxes and insurance are separate.
Understand the payment and interest comparison
The target payment is the amount needed to amortize the entered balance over your selected timeline. “Extra above scheduled payment” is the positive difference between that amount and the payment calculated over your remaining term. Target total interest equals the target payment multiplied by the number of monthly payments, minus the starting balance.
“Interest difference” compares the two modeled repayment paths. It excludes fees and prepayment penalties. Choosing a target longer than your remaining term does not give you permission to lower your required payment; changing the contractual payment would require an arrangement with your lender.
Make sure extra payments reduce principal
Ask your servicer how to designate additional money as a principal payment, and check the next statement to confirm how it was applied. This estimate assumes immediate principal application. A payment applied differently or on a different date can produce a different result. Continue making your required payments on schedule.
For a one-time lump sum or a mixture of monthly and annual extra payments, use the mortgage calculator’s extra-payment options. To inspect individual payments and the changing balance, explore the amortization calculator.
Prepayment penalties: check your loan before paying early
Some mortgages charge a fee for early repayment. Depending on the contract, a penalty may apply to a full payoff, refinancing, or a large lump-sum reduction during a specified period. Smaller extra principal payments usually do not trigger one, but check your loan documents and confirm the terms with your servicer. The CFPB’s explanation of prepayment penalties describes these distinctions. This calculator does not include a penalty, so compare any applicable charge with the modeled interest reduction separately.
Keep the payoff plan within your budget
Compare several target timelines rather than assuming the shortest is best for you. Leave room for emergency savings, other debts, repairs, and ongoing housing costs. Paying off the mortgage does not eliminate property taxes, homeowners insurance, maintenance, or association fees. The calculation shows the payment required by a mathematical model; it does not assess your household’s ability to sustain that payment.
Request an official payoff quote for the final payment
Your statement balance is not necessarily the amount needed to close the loan. A dated payoff quote can include interest through the payment date, unpaid fees, and any applicable penalty. Request it from your lender or servicer when you are ready to repay the loan in full. See the CFPB’s guide to payoff amounts versus current balances. This calculator’s result is a planning estimate, not that final quote.
