Credit Card Payoff Calculator
Estimate a fixed-rate payoff and audit every payment to the cent. Your balance and plan stay in this browser.
How to estimate your payoff time
Use the balance and purchase APR shown on your current statement, then enter a monthly amount you can evaluate as a planning scenario. The result reports the estimated number of payments, total interest, total paid, and the exact smaller final payment when the normal amount is more than the final balance plus interest.
If you are working toward a deadline, switch to Pay off in N months. The target solver tests whole-cent payments against the same ledger and verifies that one cent less misses the target. It does not use a separate shortcut formula for the displayed schedule.
How the cent-reconciled schedule works
For each modeled month, interest is the opening cent balance multiplied by the APR and divided by 12, rounded half up to the nearest cent. The actual payment is the smaller of your planned amount or the remaining balance plus that month's interest. Principal equals payment minus interest, so every visible row and the downloaded CSV reconcile to the displayed totals.
A payment at or below the first month's modeled interest does not reduce principal and is rejected as non-amortizing under this model. A payment that decreases the balance but needs more than 600 months is labeled beyond the supported 50-year horizon rather than “never.”
Why your statement can differ
The Consumer Financial Protection Bureau explains that card interest may be based on daily balances and that a daily periodic rate may use a 360- or 365-day divisor. A card can also have separate balances with different APRs, and grace periods or payment allocation rules can affect actual charges.
The two CFPB source links below were rechecked on September 27, 2026. Use your current statement and card agreement for account-specific terms.
This calculator uses one unchanged purchase APR, no new purchases, no fees, and one payment at the end of each modeled month after monthly interest. It does not cover cash advances, balance transfers, promotional or deferred interest, variable rates, issuer minimums, delinquency, debt consolidation, credit-score effects, or personalized financial advice.
Private, browser-only calculation
The payoff calculation, copy receipt, and CSV schedule are created locally in your browser. The tool does not put your balance, APR, payment, target, schedule, or result into the page URL, send it to a payoff service, or save it between visits. Reset clears the form and current result.
Use the schedule as an auditable planning worksheet, then compare it with your latest statement and card agreement. Ask the issuer for exact figures when your account has any condition excluded by this model.
Frequently asked questions
How do I estimate how long it will take to pay off a credit card?
Enter the current balance, purchase APR, and the fixed amount you plan to pay each month. This calculator adds one month of APR/12 interest, applies the payment, and repeats until the cent balance reaches zero or the 600-month limit is reached.
How much would I need to pay each month for a target payoff time?
Choose Pay off in N months. The calculator finds the smallest whole-cent planned payment that clears the modeled balance within your selected 1–600 month target, using the same month-by-month ledger shown in the result.
Why can my credit card statement show different interest?
Issuers may use average daily balances, daily periodic rates, different APR buckets, grace-period rules, fees, and payment timing. This calculator intentionally uses one fixed purchase APR divided by 12, so it is a planning estimate rather than a statement replica.
Is this an exact payoff quote or financial advice?
No. It is a browser-only estimate under the assumptions shown beside the form. Check your statement and card agreement or contact your issuer for exact figures and your current payoff information.
