Credit Card Payoff Calculator: Minimum vs. Fixed Payments
How long a balance takes to pay off, what it costs in interest, and the month your utilization drops under 30% and 10% — the point where paying down starts to show in your score.
Paying down a card does two things for someone building or rebuilding credit: it stops the interest, and it lowers the utilization ratio that scoring models read from your statement balance. This calculator shows both. Enter the balance, the APR from your statement, and what you plan to pay each month. Add the card’s credit limit to see when your reported utilization crosses the 30% and 10% lines.

Minimum payment is modeled as the % of the balance plus that month’s interest, or the floor, whichever is more — a formula many large issuers use. Your card’s agreement states its own formula; change the two fields to match it.
Enter a balance, APR and payment.
| Plan | Monthly payment | Months to pay off | Total interest | Under 30% util. | Under 10% util. |

Interest is charged monthly at APR ÷ 12 on the balance after each payment; issuers that use the average daily balance will differ by a few dollars. Assumes no new purchases, fees or rate changes. Estimate only.
Why the minimum takes so long
A minimum payment that is a percentage of the balance shrinks as the balance shrinks, so most of each payment keeps going to interest. On the default example — $3,000 at 24.99% with a minimum of 1% plus interest — the first minimum is about $92, and only $30 of that reduces the balance. The rest is interest. Because the payment falls with the balance, the last few hundred dollars are paid at the $25 floor for months.
A fixed payment works the other way: the interest portion falls each month while the payment stays the same, so more and more of it goes to principal. That is why a fixed $150 on the same card finishes in 27 months with about $921 of interest, while the minimum stretches to roughly 15 years and about $5,100 of interest — more than the original balance. Run your own numbers above; the table shows the exact gap.
Federal law makes your statement show this too. Under the Truth in Lending Act as amended by the Credit CARD Act of 2009, a card statement must include a minimum-payment warning: how long it would take to pay off the balance making only minimum payments, the total you would pay that way, and the monthly payment that would pay it off in 36 months, along with the total cost at that payment. The calculator’s 36-month row is the same idea, so you can check it against your statement.
What paying down does to your score
Amounts owed is the second-largest part of a FICO Score (FICO weights it at 30%), and the main measure inside it is revolving utilization: the balances reported on your cards divided by their limits. Two details matter for timing:
- It is the reported balance that counts. Most issuers report the statement balance once a month. Paying down mid-cycle lowers what is reported only if the payment posts before the statement closes. See the credit utilization guide for the pay-before-close method.
- Utilization follows what is reported now. Once a lower balance is reported, the utilization part of a score reflects it on the next pull — unlike a late payment, which stays for seven years. Newer “trended data” models such as VantageScore 4.0 also look at how your balances have moved over recent months, which is one more reason a steady paydown helps. The 30% and 10% columns tell you roughly which month’s statement first shows each line crossed.
30% and 10% are rules of thumb, not cut-offs a scoring company publishes. Lower generally scores better, as long as at least one card reports a small balance. If you have several cards, both the overall ratio and each card’s ratio can matter; the utilization calculator handles more than one card.
Ways to shorten the payoff
- Pay a fixed amount, not the minimum. Even the minimum’s first-month figure, kept constant, cuts years off. Set it as an automatic payment so a missed due date never adds a late fee or a 30-day late mark.
- Target the highest APR first if you carry balances on more than one card (the “avalanche”). It minimizes interest. Paying the smallest balance first (the “snowball”) costs more interest but closes accounts’ balances sooner; pick the one you will stick to.
- Ask for a lower APR. After 6–12 months of on-time payments, a call to the issuer costs nothing. Enter the new rate above to see what it saves.
- A balance transfer or consolidation loan can lower the rate, but transfers usually charge a fee of 3%–5% of the amount moved and need good credit to qualify, and a new loan or card adds a hard inquiry. Compare the fee to the interest the calculator shows before applying.
- Stop new charges on the card while you pay it down, or the payoff date moves. Keeping the card open with a small automatic charge preserves its limit and age; see closing a credit card before you close anything.
FAQ
How is the minimum payment on a credit card calculated?
Each issuer sets its own formula in the cardholder agreement. A common one is 1 percent of the balance plus that month's interest and any fees, or a dollar floor such as 25 or 35 dollars, whichever is more. Some issuers use a flat 2 to 3 percent of the balance. The calculator lets you set both the percentage and the floor.
Why does my statement show a different payoff time?
Statements use the issuer's own minimum-payment formula and daily interest on the average balance, and they assume you make no new purchases. Small differences in the formula or in how interest is compounded change the months and the total by a little. If the gap is large, check that the APR and minimum formula entered here match your agreement.
Does paying off a credit card raise my credit score?
Lowering the reported balance lowers your utilization, which is part of the amounts-owed category, the second-largest factor in a FICO Score. The change usually shows after the issuer reports the lower statement balance. It will not remove late payments or other negative items already on the report.
Should I close the card once it is paid off?
Usually not if it has no annual fee. Closing removes that card's limit from your total available credit, which raises utilization on any other cards with balances. A paid-off card with no fee costs nothing to keep open.
Is it better to pay twice a month?
Paying part of the bill before the statement closes lowers the balance that gets reported, which helps utilization, and it slightly reduces interest on cards that charge on the average daily balance. The total you pay each month matters far more than how many payments you split it into.
