See how much interest you'd save by paying more
See exactly how many years — and how many thousands in interest — you'd save by adding even $100/month to your mortgage. Works for extras, biweekly, or lump-sum payments.
Your loan
Extra payments
Your savings
Base P&I: $2,335Rates, taxes, and insurance can change over time — assumes your extras are applied to principal each month. Estimates only based on national averages. Always confirm with a licensed lender.
Biweekly vs monthly — what is actually happening
A biweekly schedule means 26 half-payments per year. That is 13 full payments instead of 12 — one extra payment entirely.
- Simplest to budget
- No fee programs
- Add extras anytime
- Shaves 4-6 years on 30-yr loans
- Same math as 1/12 extra each month
- Skip 3rd-party fee programs
You beat the interest clock
On a 30-year loan, the first month of interest alone can be thousands of dollars. Every dollar you can shift to principal permanently avoids interest on that dollar for every month remaining in the loan.
That is why early extra payments are worth so much more than late ones — the earlier they happen, the longer they avoid compounding interest.
Three strategies, one view
Monthly extras: the most flexible — stop anytime your budget tightens.
Biweekly equivalent: toggles on 1 extra monthly payment per year.
Lump sum: apply a bonus, tax refund, or windfall to the balance.
You can combine all three to see the compounded effect.
