Mortgage Payoff Calculator
See how extra payments could change your mortgage payoff timeline and estimated interest.
Planning note: Your current principal balance is not the same as an official payoff amount. A servicer payoff quote can include interest through the payoff date, unpaid fees and, in some loans, a prepayment penalty. Confirm how extra payments are applied before relying on the estimate.
Before sending extra principal, check your mortgage terms and servicer instructions. Some loans can have prepayment penalties, and servicers may have specific directions for principal-only payments.
What the mortgage payoff calculator estimates
This tool compares your current principal-and-interest payment plan with a plan that adds extra money toward principal. It is meant to show the direction and size of the difference—not replace your lender’s official payoff statement.
Payoff time
The calculator estimates how many monthly payments it may take to bring the entered balance to zero at the entered interest rate.
Extra payments
A recurring extra payment and a one-time extra payment reduce principal sooner, which can shorten the estimated payoff period.
Estimated interest
The comparison shows how paying principal sooner may reduce total interest over the remaining life of the loan.
Mortgage payoff questions worth knowing
Should I enter my total mortgage payment?
Use the principal-and-interest portion when possible. Property taxes, homeowners insurance, HOA fees and other escrow items do not pay down the loan balance.
Will my lender apply extra money to principal?
Lender procedures vary. Before sending extra money, check how your servicer applies additional payments and whether you need to mark them as principal-only.
Why might my lender’s payoff date be different?
Actual payoff amounts can differ because of payment timing, accrued interest through the payoff date, fees, rounding and the exact terms of your mortgage. Ask your servicer for an official payoff statement when you are ready to pay the loan off.
Is paying the mortgage early always the best choice?
Not necessarily. Emergency savings, higher-interest debt, retirement goals, taxes and other priorities can matter too. This calculator helps compare the mortgage math so you can consider it alongside the rest of your financial picture.
This calculator provides planning estimates only. Confirm payment application, loan terms and an official payoff amount with your mortgage servicer.
