Home/Credit card payoff calculator

White Glove tool · credit math

See what the
minimum costs.

Model a credit-card balance at a steady monthly payment and watch payoff time, total interest, and the comparison with a fixed-rate personal-loan scenario change together. The result is context—not a quote or a promise of savings.

The short answer

A payment can look manageable while interest keeps the balance moving slowly.

Credit-card interest is added each period, so the payment amount matters as much as the APR. Use the model to see how a sustainable payment changes the timeline, then compare the actual card agreement or loan offer.

01Payment

How much reaches principal each month.

02Time

How long the balance remains open.

03Interest

The modeled cost of carrying it.

Illustratively, the fixed-rate comparison could reduce modeled total cost by about $5,274.16 if the terms shown were available and the balance were otherwise identical.

Estimate only. It does not account for card issuer minimum-payment rules, daily compounding conventions, fees, promotional rates, late payments, an upfront fee beyond the modeled amount, lender eligibility, prepayment terms, or changes in APR. Review the provider’s full disclosures and your budget.

How to use it

Start with the payment you can keep.

Use the balance you actually carry, then stress-test a payment that fits your budget. A lower payment can extend the timeline; a higher payment can change how much interest compounds before principal falls.

  • Compare APR and fees together.
  • Look at total paid, not only the minimum.
  • Review whether the balance actually amortizes.

Keep the context

A personal loan is not automatically cheaper.

Compare the actual APR, fees, term, payment, and total cost. The calculator is a frame for the conversation, not individualized financial advice.

Questions, answered plainly

How does a credit-card payment affect payoff time?

Each period, interest is added to the balance before the payment reduces principal. A larger payment generally reduces payoff time and total interest, while a payment that does not cover the modeled first-month interest will not amortize the balance.

Is this calculator exact?

No. It is an illustrative model using the APR, balance, and payment you select. Actual card agreements may use different minimum-payment rules, daily balances, fees, promotional rates, and payment timing.

Can a personal loan automatically save money on card debt?

No. Compare the actual APR, origination fees, term, payment, and total cost. A personal loan can have a lower modeled interest cost in some scenarios, but it is not automatically cheaper or better.
