Understand the cost of revolving credit

Credit card calculators that explain the trade-offs

Compare payment plans, interest charges, balance transfers, utilization and payoff timing. These estimates use the APR and terms you enter—not a lender quote or credit-score prediction.

Results are educational estimates. Issuer daily-balance calculations, payment allocation, fees, promotional terms, and variable rates may change actual charges.

Payoff balance chart

After calculating a fixed-payment payoff, this chart shows the estimated balance declining month by month. It is based on monthly APR/12 interest and payments at month end.

How to use these calculators responsibly

Start with the balance, APR and payment amount from your latest statement. Use the fixed-payment tool to see how long your current payment might take. Next, use the target-date calculator to compare a shorter payoff plan. If you're considering a balance transfer, compare the transfer fee with interest saved during the introductory period and confirm the post-promotion APR separately.

Utilization is a ratio, not a guarantee about a credit score. The minimum-payment tool is a simplified scenario: real card issuers can use different minimum-payment formulas, add fees, and change rates. Always use the issuer's required minimum payment and statement disclosures for actual obligations.
