Loan Payoff Time Calculator
Loan Payoff Time Calculator
Given a starting balance, an interest rate, and a fixed monthly payment, there's a precise number of months required to reach zero — this calculator solves for that directly using the same math lenders and credit card companies use internally.
People carrying credit card or personal loan debt use this to see the real payoff timeline, which is often much longer than expected once compounding interest is factored in — a key reason minimum-payment-only strategies can take years or even decades to clear a balance.
- Payment Must Exceed Interest: Your monthly payment must be greater than the first month's interest charge, or the balance will never reach zero.
- Small Rate Changes, Big Time Differences: Because interest compounds monthly, a few percentage points of rate can add months or years to the payoff timeline.
- Same Math as Credit Cards: This is the exact calculation behind the "minimum payment warning" disclosures required on credit card statements.
Why does my calculator show an error or blank result?
If your monthly payment doesn't exceed the interest accruing on the balance each month, the loan mathematically never gets paid off — increase the payment amount above the monthly interest charge.
Why do credit card minimum payments take so long to pay off a balance?
Minimum payments are often set just above the monthly interest charge, meaning very little goes toward the actual balance each month — this calculator shows exactly how many months that translates to.
