About PayOffPal
PayOffPal is a free mortgage extra payment calculator built for homeowners who want to understand the real impact of paying even a little extra toward their principal each month. We believe that mortgage calculators shouldn't be hidden behind paywalls, email gates, or upsells for refinancing services.
Why Extra Payments Matter
On a typical $350,000 mortgage with 20% down at 6.5% interest over 30 years, the total interest paid exceeds $340,000 — nearly as much as the original loan amount. An extra $200 per month directed at principal reduces the payoff timeline by roughly 8 years and saves over $100,000 in interest.
Most homeowners never see this math presented clearly. Banks send amortization schedules, but they don't show you what happens if you pay more. PayOffPal fills that gap with an instant, visual breakdown.
How We Calculate
We use standard amortization formulas — the same math your lender uses. For every extra dollar you add:
- Principal is reduced immediately
- Future interest charges drop (because interest is calculated on the remaining balance)
- The loan term shortens
- Total lifetime interest paid decreases
Our calculator runs these projections to the month, showing you exactly when your mortgage ends with and without extra payments.
Privacy First
All calculations happen in your browser. We do not store, log, or transmit any financial data you enter. There is no account to create, no email to provide, and no data to sell. Your mortgage details stay on your device.
Our Editorial Standards
Our guides are researched and written by the PayOffPal editorial team using standard amortization math and publicly available industry data — including Fannie Mae/Freddie Mac's published loan pricing adjustments and FICO's own scoring research where credit-score topics are covered. We check figures before publishing and update them as rates and terms change.
We are not mortgage brokers, lenders, or financial advisors. Our content is meant to help homeowners understand their options and ask better questions — not to replace advice from a qualified lender or financial advisor for your specific situation.
