Based on your results — what to do next:
Could a lower rate save even more?
Extra payments save $107,611 — but refinancing from 6.75% to a lower rate might save even more with no extra cash required.
What if you invested instead of paying extra?
$200/mo extra vs. investing it — compare the guaranteed mortgage savings against market growth at 7%.
Build a payoff lump-sum faster
A $10,000 lump sum shortens your mortgage. Plan how long it takes to save that amount.
A mortgage payoff calculator shows how making extra payments against your principal reduces the total interest you pay and shortens the life of your loan. Enter your current balance, interest rate, and how much extra you can pay — this tool calculates your new payoff date, total months saved, and exact dollar savings using the same amortization math your lender uses.
How Early Mortgage Payoff Is Calculated
When you pay extra each month, the entire extra amount goes directly to principal — not interest. This reduces the balance on which next month's interest is calculated, creating a compounding effect that accelerates payoff. The calculation uses the standard amortization formula to find the new term given a higher monthly payment.
| Variable | Definition |
|---|---|
| n | Number of months to payoff (what we solve for) |
| P | Current remaining principal balance |
| r | Monthly interest rate = Annual rate ÷ 12 |
| M | Total monthly payment (regular + extra) |
Example: $280,000 balance at 6.75%, paying $2,016/month ($1,816 regular + $200 extra). The formula gives n = 280 months (23 years 4 months) vs. the original 360 months (30 years) — saving 80 months and about $64,000 in interest.
💡 Expert Pro-Tip
Apply extra payments as "principal only" — always verify with your lender. Some servicers apply extra payments to future scheduled payments (prepaying next month's bill) rather than reducing principal immediately. This is a costly mistake. Call your servicer or use their online portal to ensure any extra payment is designated "applied to principal only." This single step ensures every extra dollar immediately reduces the balance on which interest is charged.
Frequently Asked Questions
How much does an extra $200/month save on a 30-year mortgage?⌄
On a $280,000 mortgage at 6.75%, adding $200/month extra saves approximately $64,000 in interest and cuts 6+ years off your loan. Exact savings depend on your remaining balance and rate — enter your numbers above.
Is it better to pay extra on my mortgage or invest?⌄
Paying extra gives a guaranteed return equal to your mortgage rate (e.g., 6.75%). Investing in stocks has averaged 7–10% historically but with volatility and risk. Many advisors recommend: max out 401(k) employer match first, then split extra cash between mortgage prepayment and taxable investing.
Does making bi-weekly payments pay off a mortgage faster?⌄
Yes — bi-weekly payments create 26 half-payments per year (13 full payments), shaving 4–5 years off a 30-year mortgage. To achieve this without a fee, simply make one extra full payment per year, applied to principal.
Can I pay off my mortgage early without penalty?⌄
Most U.S. mortgages originated after 2014 have no prepayment penalty. Check your loan documents for 'prepayment penalty' language. Loans from major conventional lenders (Fannie/Freddie) and FHA/VA loans typically have no penalty.
