Our free mortgage payoff calculator shows exactly how much interest you can save by making extra payments – and how many years early you can pay off your loan. Enter your loan balance, rate, and extra payment amount to instantly see your new payoff date.
A mortgage payoff calculator uses your remaining loan balance, interest rate, and any extra monthly payment to compute your new payoff timeline. It compares your standard amortization schedule against an accelerated one, so you can see the exact dollar amount of interest you’d save. According to the Consumer Financial Protection Bureau, making even one extra payment per year can shave years off a 30-year mortgage.
Use this mortgage payoff calculator to compare three proven payoff strategies. First, add a fixed extra amount each month – even $100 extra can cut years off a 30-year loan. Second, make one additional full payment per year (a 13th payment), which is the same benefit you get from switching to biweekly payments. Third, make a lump-sum principal payment whenever you have savings available. Enter each scenario into the mortgage payoff calculator above to see exactly which method saves the most for your situation.
On a $300,000 mortgage at 7% for 30 years, your standard monthly payment is $1,996. Adding just $200/month extra saves approximately $87,000 in interest and cuts the loan to about 22 years. Our mortgage payoff calculator runs this math instantly for any balance and rate. The earlier in the loan you start making extra payments, the more interest you save – because more of your payment currently goes to interest rather than principal.
- Adding just $100/month extra to a $300K loan at 7% saves over $40,000 in interest and cuts 4+ years off your loan
- Extra payments in the first 5-10 years of your mortgage have the greatest impact on interest savings
- Always specify that extra payments go toward principal only – not applied to future payments
- A lump-sum payment of $10,000 early in the loan can save 2-3x that amount in interest
- Paying off early may trigger a prepayment penalty on some older loans – check your note first

How accurate is this mortgage payoff calculator?
This mortgage payoff calculator uses standard amortization formulas consistent with how lenders calculate payoff schedules. Results may vary slightly due to rounding and how your lender applies extra payments. Always confirm with your lender before making financial decisions.
Does making extra payments reduce my monthly payment?
No – extra payments reduce your loan balance and payoff timeline, but your required monthly payment stays the same. Use the mortgage payoff calculator to see how additional payments shorten your term rather than lower your required amount.
What’s the fastest way to pay off a mortgage early?
The most effective method shown in our mortgage payoff calculator is combining a consistent extra monthly payment with occasional lump-sum payments from tax refunds or bonuses. This compound approach saves significantly more than either method alone.
How does a mortgage payoff calculator differ from a refinance calculator?
A mortgage payoff calculator assumes you keep your current loan and accelerate payments. A refinance calculator models replacing your loan with a new one at a different rate or term. Use both to decide whether extra payments or refinancing saves more.

Dave Ramsey Mortgage Payoff Calculator
Dave Ramsey is one of the most well-known advocates for paying off your mortgage early. His “Baby Step 6” specifically calls for paying off the home mortgage as the final major debt milestone before building wealth. Use the calculator above to run any of Dave Ramsey’s recommended strategies:
What does Dave Ramsey say about paying off your mortgage early?
Dave Ramsey recommends paying off your mortgage as fast as possible – ideally on a 15-year fixed-rate mortgage from the start. His core philosophy: every dollar you pay toward principal eliminates future interest charges. He recommends throwing all “extra” money at the mortgage once Baby Steps 1–5 are complete (emergency fund, debt payoff, retirement contributions, and college savings). He often talks about making one extra mortgage payment per year or rounding up your payment to the nearest hundred.
How much faster can you pay off your mortgage with extra payments?
One extra monthly payment per year on a 30-year mortgage typically shortens the payoff by 4–5 years and saves tens of thousands in interest. Adding $200/month extra on a $300,000 mortgage at 7% cuts payoff from 30 years to about 22 years and saves approximately $100,000 in interest. Use the calculator above to enter your extra monthly payment amount and see your personal payoff date and savings.
Is the Dave Ramsey mortgage payoff strategy right for everyone?
Dave Ramsey’s approach is psychologically powerful and mathematically sound when mortgage rates are high relative to expected investment returns. The counterargument – made by many financial advisors – is that when mortgage rates are low (under 4%), investing extra money in the stock market often produces better long-term returns than paying down mortgage principal early. At current rates (6–7%+), the guaranteed “return” from paying down your mortgage becomes much more compelling, and Ramsey’s advice aligns with mainstream financial guidance.
How do I use this as a Dave Ramsey mortgage payoff calculator?
Enter your current loan balance, remaining term, and interest rate. Then in the “Extra Monthly Payment” field, enter whatever additional amount you can apply to principal each month. The calculator will show you: your new payoff date, total months saved, and total interest saved. Try Dave Ramsey’s classic suggestion of rounding your payment up to the nearest $100 to see how much of a difference even a small extra amount makes over time.
