The one rule: fix your payment
Card minimums decline as your balance declines — a design that stretches payoff into decades. Freezing your payment at any fixed number converts the card into a normal amortizing loan with a real end date. That's the entire trick, and the ladder above prices each step of aggression. For the mechanics of daily compounding and the grace period, read how credit card interest works; for multiple cards, sequence them with the debt snowball calculator.
Frequently asked questions
How long will it take to pay off my credit card?
Divide-and-guess doesn’t work because interest compounds while you pay. Enter your balance, APR, and a fixed monthly payment above: a $5,000 balance at 24% with $200/month takes about 2 years 9 months and roughly $1,600 of interest. The ladder table shows how +$50 or +$100 changes that.
What payment do I need to be debt-free by a target date?
Switch the calculator to goal mode and enter the months: it computes the exact fixed payment using the same amortization math as a loan. Paying a FIXED amount — rather than the card’s declining minimum — is the single biggest accelerator.
Why does paying only the minimum take decades?
Minimums are typically interest + 1% of the balance and shrink as the balance shrinks, stretching the timeline enormously. Your statement’s “minimum payment warning” box shows the issuer’s own projection. See our guide on the minimum-payment trap for the mechanics.
Should I use a balance transfer instead?
A 0% transfer (typical fee 3–5%) stops interest for 12–21 months — mathematically strong if you can clear the balance within the promo window. Compute the payment needed here with goal mode set to the promo length, add the fee, and compare.
Which card should I pay first if I have several?
Highest APR first (avalanche) minimizes interest; smallest balance first (snowball) builds momentum. Our debt snowball calculator compares both on your actual cards, with payoff dates.
Does carrying a small balance help my credit score?
No — that’s a persistent myth. Utilization is reported whether or not you pay interest; paying in full builds the same history for free.
