About This Calculator
The Mortgage Payoff Calculator helps you determine how making extra payments can accelerate your mortgage payoff and save thousands in interest. Enter your current loan balance, interest rate, monthly payment, and any extra payment amount to see the impact.
This calculator shows you exactly how much time and money you can save by making additional principal payments each month, helping you make informed decisions about paying down your mortgage faster.
Formula & Calculation Method
Mortgage Payoff Calculation:
Monthly Interest = Remaining Balance × (Annual Rate ÷ 12 ÷ 100)
Principal Payment = Total Payment - Monthly Interest
New Balance = Remaining Balance - Principal Payment
Process repeats until balance reaches zero
Extra payments directly reduce the principal balance, which reduces future interest calculations and accelerates payoff time.

Frequently Asked Questions
How much can I save with extra payments?
Extra payments can save thousands in interest and reduce payoff time significantly. Even $100 extra per month on a $300,000 mortgage at 6.5% can save over $30,000 in interest and reduce payoff by 3-4 years.
Should I make extra payments or invest?
Compare your mortgage interest rate to potential investment returns. If your mortgage rate is higher than expected investment returns, paying extra may be better. Consider your overall financial goals.
Do extra payments reduce my monthly payment?
No, extra payments reduce your principal balance and payoff time, but your regular monthly payment stays the same unless you refinance.
Can I make lump sum payments?
Yes, many lenders allow lump sum principal payments. This calculator shows monthly extra payments, but lump sums work similarly by reducing principal immediately.
