Credit Card Calculators

Credit cards are the most expensive form of consumer debt in widespread use. Average APRs hover near 22-26%, and minimum payments are deliberately structured so that paying only the minimum keeps you in debt for 20+ years on most balances. Our credit card calculators are designed to make the real cost of carrying a balance — and the value of paying it down faster — concrete.

The minimum payment calculator shows how long it takes to pay off a balance if you only ever pay the minimum (typically 1-3% of the balance plus interest). The result is usually shocking: a $5,000 balance at 24% APR takes 25+ years to repay at minimum payments, with total interest paid exceeding the original balance several times over.

The credit card payoff calculator inverts the question: given a target payoff date or a target monthly payment, what does the total interest paid look like? Adding even $50 per month to the minimum can shave a decade off the timeline.

Balance transfer calculators help evaluate the math behind 0% intro APR offers. Most balance transfers come with a 3-5% transfer fee — meaningful but often worth paying if you can clear the balance within the intro period. Our calculator computes the break-even point so you know whether the transfer saves money or just delays the problem.

Calculator math follows the standard credit card amortization conventions: monthly interest accrual at APR/12, minimum payment as the greater of (1-3% of balance + interest) or a floor amount (often $25 or $35). Specific minimum payment formulas vary by issuer — Chase, Citi, Capital One, Amex, and Discover each have slightly different rules — so for an exact payoff projection on your specific account, use the disclosure on your statement. Cash advances and balance transfers often carry different APRs from purchases; the calculators here assume a single APR.
