$5,000 at an assumed 22% APR: 230 monthly payments

The assumed minimum is max($25, 1% of the opening balance plus that month's interest). With no extra payment, fees or new charges, monthly APR/12 accrual gives 230 months and $8,099.77 in interest. The 22% rate is an example, not a current market average.

Change the percentage and dollar floor to explore the formula. Check the statement: an issuer may use a different minimum or daily accrual method.

Minimum-payment assumptions

Each month: the greater of the dollar floor or the balance percentage plus that month's interest. Match your issuer's terms; other minimum formulas are not modeled.

Minimum-only comparison using the selected formula: 230 months and $8,099.77 interest. Your plan reduces modeled interest by $0.00.

Estimate assumes a constant APR, monthly interest at APR/12 before payment, no new purchases or fees, and no intermediate rounding. Actual cards may use daily balances, multiple APRs and different minimum rules. This does not model grace periods or confirm that a fixed payment meets your statement minimum.

Why the minimum can shrink as your balance falls

In this example, the first month's interest is $91.67. Adding 1% of the opening balance makes the first payment $141.67. As the balance falls, the modeled minimum falls until the $25 floor applies.

Keeping a fixed payment can reduce the repayment time. The comparison uses the same starting balance and APR, with no new spending or fees. Your issuer's calculation may differ.

Fixed-payment examples: $5,000 at an assumed 22% APR

Payment per month	Payoff cycles	Interest
$100.00	137 months	$8,678.06
$150.00	52 months	$2,798.05
$250.00	26 months	$1,285.72
$500.00	12 months	$574.44
$1,000.00	6 months	$294.02

Interest accrues at APR/12 before each payment; the final payment may be smaller. Values are calculated without intermediate rounding and displayed to cents.

Check the terms before changing your repayment plan

Balance transfer: compare the fee, promotional end date, post-promotion APR and treatment of new purchases. A 0% offer is not necessarily free.
Consolidation loan: compare the written APR, fees and total repayment over the full term. A lower monthly bill can still mean more interest if repayment takes longer.
Multiple cards: compare highest-APR-first and smallest-balance-first using the multi-debt calculator, whose entered minimums remain fixed.

Primary sources and model limits

The model uses one balance, static APR, monthly interest before payments and no fees or new charges. It does not model daily balance changes, multiple APR categories, grace periods or issuer-specific payment allocation.

Credit Card Calculator FAQ

How is credit card interest calculated?

Many issuers calculate interest from daily balances, and different transaction types may have different APRs. This calculator estimates one balance at a constant APR using monthly APR/12 accrual before payments. It does not reproduce every issuer's statement calculation.

How does this calculator set the minimum payment?

It uses the greater of a dollar floor or a percentage of the opening balance plus that month's interest. The example uses a $25 floor and 1% balance percentage. Adjust these assumptions and check your agreement; formulas with other rules are not modeled.

Does paying more than the minimum help my credit score?

Reducing a reported balance can lower credit utilization, but a score change depends on the scoring model and the rest of your credit file. This repayment calculator does not predict a point increase or its timing.

Should I close a paid-off credit card?

Consider fees, spending risk and the effect on available credit. Closing an account can increase utilization, but keeping it open may not suit your circumstances. There is no universal answer or guaranteed score outcome.

What is a credit card grace period?

A grace period is the interval between the billing cycle ending and payment being due. When a card provides one and its conditions are met, paying the purchase balance in full by the due date can avoid purchase interest. Carrying a balance or making cash advances can change this; the calculator does not model grace periods.

Can I ask for a lower credit card APR?

You can ask the issuer about a lower APR or available hardship options. Approval and terms depend on the issuer and your circumstances. If the rate changes, rerun the estimate with the agreed rate; no success percentage is assumed.

Methodology and editorial standards

Each calculator uses its own inputs and method. Review the labels, units and assumption notes shown with the result. Costs, taxes, fees, benefits and other factors are not modeled unless the page or calculator explicitly says they are. A fixed-rate projection is a scenario, not a forecast or personalized recommendation.
