Mortgage Payoff Calculator

What if you paid just $200 extra on your mortgage each month? This calculator shows you exactly how many years you'd cut off your loan — and how much interest you'd save. The results often surprise people.

What Does This Calculator Do?

Enter your current mortgage details and any extra monthly payment you're willing to make. The calculator computes your new payoff date and total interest savings compared to making minimum payments only.

How to Use This Calculator

2. Enter your interest rate.
3. Enter your remaining loan term in years.
4. Enter the extra amount you want to pay each month.
5. Click Calculate to see your new payoff date and savings.

How Early Payoff Is Calculated

The calculator applies your extra payment to the principal balance each month. A lower balance means less interest accrues, so more of each future payment hits the principal — creating a snowball effect that accelerates payoff rapidly.

Example Calculation

Current balance: $250,000 | Rate: 6.75% | Remaining term: 25 years

• Normal monthly payment: ~$1,741
• Extra payment: $300/month
• New payoff: 19 years 4 months (saves 5 years 8 months)
• Interest saved: ~$62,400

Why Pay Off Your Mortgage Early?

Paying off your mortgage early gives you guaranteed, risk-free "savings" equal to your interest rate. In a 6.75% rate environment, that beats many savings accounts. It also eliminates your biggest monthly expense and frees up cash flow for retirement or other goals.

Common Mistakes to Avoid

• Not labeling extra payments as principal — always tell your servicer the extra is for principal only, not next month's payment.
• Ignoring prepayment penalties — some loans charge a fee for early payoff. Check your loan documents first.
• Paying off low-rate debt before high-rate debt — if you have 20% credit card debt, pay that off first.
• Skipping your emergency fund — keep liquid savings before aggressively prepaying a mortgage.

Frequently Asked Questions

Does it matter if I make biweekly payments instead of monthly?

Yes. Biweekly payments result in 26 half-payments per year — equivalent to 13 full monthly payments instead of 12. That extra payment each year adds up to significant savings over time.

What's better — extra monthly payments or a lump sum?

Both reduce your balance and save interest, but a lump sum applied today saves more than the same amount spread over time, since it starts reducing interest accumulation immediately.

Will paying off my mortgage early hurt my credit score?

Paying off a loan typically causes a small, temporary dip because it closes a long-standing account. For most people, the financial benefit of payoff far outweighs any credit impact.

Should I pay off my mortgage before retirement?

Many financial advisors recommend entering retirement mortgage-free, as it dramatically reduces your required monthly income. Use our Retirement Calculator to model both scenarios.

Can I refinance instead of making extra payments?

Refinancing to a lower rate or shorter term can also save interest. Compare options with our Refinance Calculator.

What if I can only afford a small extra payment?

Even $50 extra per month makes a meaningful difference over a 30-year loan. Small consistent extra payments are more valuable than sporadic large ones.

Conclusion

Paying off your mortgage early is one of the simplest wealth-building moves available. Use this calculator to find an extra payment amount that fits your budget, then commit to it every month. The interest savings will speak for themselves.
