How it works
Use this calculator to estimate how long it will take to pay off a mortgage.
What this calculator does
The mortgage payoff calculator estimates payoff time, total interest, and total paid from your current balance, rate, monthly payment, and any extra payment.
Mortgage Payoff Formula
Each month, interest is added to the balance and the payment reduces principal.
Principal Paid = Monthly Payment - Monthly Interest
Example calculation
If your mortgage balance is 250,000, rate is 6.5%, and you pay 1,800 per month plus 200 extra, the calculator estimates the new payoff timeline.
When to use this calculator
- planning early mortgage payoff
- testing extra monthly payments
- estimating total interest
- comparing payoff strategies
FAQs
Do extra payments reduce interest?
Yes. Extra principal payments usually reduce future interest and shorten the loan.
