5 Adjust to Compare Scenarios
Try different payment amounts to see how increasing your payment shortens your payoff time and reduces interest costs.
How the Mortgage Payoff Calculation Works
The calculator uses the standard mortgage amortization formula:
Monthly Interest Rate
r=12×100Annual Rate
Payoff Time Formula
n=−ln(1+r)ln(1−rP/A)
Where:
- P = loan amount
- A = monthly payment
- r = monthly interest rate
- n = number of months to pay off
Example Calculation
If your loan amount is $250,000, interest rate 7.5%, and monthly payment $2,000:
- Monthly rate = 0.075 / 12 = 0.00625
- Payoff time ≈ 187 months
- That’s 15 years + 7 months
- Total interest paid ≈ $124,000+
The tool performs this entire calculation instantly for you.
