Find out exactly when your loan will be paid off. Enter your balance, rate, and payment to calculate your payoff date and total interest paid.
Knowing exactly when your loan will be paid off provides peace of mind and a tangible goal to work toward. Whether you are paying down a personal loan, auto loan, student loan, or any other fixed-rate debt, this calculator takes your current balance, interest rate, and monthly payment to determine your precise payoff date and total interest paid.
Unlike standard amortization calculators that start from a new loan, this Loan Payoff Date Calculator works with your current remaining balance — perfect for mid-loan analysis. You can see how many payments remain, the exact calendar month you will be debt-free, and how much total interest you will pay from this point forward.
This tool also lets you see what happens if you increase your monthly payment. Even a modest payment increase can shave months or years off your payoff date and save significant interest. Enter different payment amounts to find the sweet spot between affordability and speed.
When you are in the middle of repaying a loan, the original amortization schedule may no longer be accurate if you have made extra payments or missed payments. This calculator gives you an up-to-date projection based on your current balance, showing you exactly when you will be free of this debt and how much more interest you will pay.
Number of payments: n = −log(1 − r×B/M) / log(1+r) Where B = current balance, r = monthly rate (APR/12), M = monthly payment. Payoff Date = Current Date + n months. Total Interest = (M × n) − B. Condition: M must be greater than B × r (monthly interest) or the loan will never be paid off.
Result: Paid off in 38 months (March 2029), $1,275 total interest remaining
With a $12,000 balance at 8% APR and $350 monthly payment, you have 38 payments remaining. The monthly interest starts at $80 and decreases as the balance drops. Total interest from now through payoff is $1,275. Increasing the payment to $400 would reduce the timeline to 33 months and save $141 in interest.
Having a specific, calculated payoff date transforms an abstract debt into a concrete goal. Research in behavioral finance shows that people are more likely to complete goals with specific deadlines. Seeing that you will be debt-free in "March 2029" is far more motivating than knowing you have "a few years left."
The relationship between payment size and payoff date is not linear. On a $20,000 loan at 10%, increasing your payment from $300 to $350 (a 17% increase) reduces the payoff time by 18 months (a 20% reduction). The leverage effect is even stronger at higher interest rates because more of each extra dollar goes to principal reduction.
If your loan has been active for a while, the original amortization schedule may no longer reflect reality — especially if you have made extra payments, had a rate change, or restructured the loan. This calculator gives you an accurate current-state projection regardless of the loan's history.
The calculator uses the loan payoff formula: n = −log(1 − r×B/M) / log(1+r), where B is the balance, r is the monthly rate, and M is the monthly payment. This gives the number of remaining payments, which is added to today's date to determine the payoff month.
If your monthly payment is less than or equal to the monthly interest charge (balance × monthly rate), the payment only covers interest and never reduces the principal. The loan would never be paid off. Your payment must exceed the monthly interest for any principal reduction to occur.
Extra payments reduce the principal faster, which decreases the interest charged in subsequent months. Even small additional payments can shave months or years off the payoff timeline. A $50 increase on a $15,000 loan at 10% can save over 6 months and hundreds of dollars in interest.
This calculator assumes a fixed interest rate. For variable-rate loans, the projection is accurate as long as the rate stays the same. If your rate changes, re-run the calculator with the new rate to get an updated payoff date.
Yes, but credit cards compound daily and have variable minimum payments, making this calculator a rough estimate. For credit card-specific calculations, use a dedicated credit card payoff calculator that accounts for daily compounding and minimum payment formulas.
Use your current actual balance — not the original loan amount — along with your current rate and payment. The calculator works with whatever balance you provide, automatically accounting for any extra payments you have already made.
