Find out exactly how long it takes to pay off your credit card debt and how much interest you'll pay. Compare minimum payments vs fixed payments to get out of debt faster.
Payoff time, interest cost & minimum payment comparison
This credit card payoff calculator shows the painful math behind minimum payments. On a $5,000 balance at 22% APR — close to the 2025 national average for US credit cards — the minimum payment might start at $100 per month. Pay only the minimum and you'll spend nearly 7 years paying off that balance and hand the bank over $3,800 in interest charges on top of the original $5,000. That's the minimum payment trap: it feels manageable each month while quietly compounding into a much bigger debt problem.
Switching to a fixed payment changes everything. Pay $250 per month on the same $5,000 balance at 22% APR and you're debt-free in about 26 months with roughly $1,100 in total interest — saving $2,700 over the minimum-payment path. Even bumping from $100 to $150 per month slashes years and thousands off your payoff. The avalanche method — directing extra payments to the highest APR card first — is mathematically optimal for reducing total interest across multiple cards.
Credit card issuers set minimum payments at about 1%–2% of your balance — just enough to keep you paying interest almost indefinitely. A $10,000 balance at 20% APR on minimums takes 30+ years to pay off.
The average US credit card APR exceeded 21% in 2025. At that rate, $5,000 in debt costs you about $1,050 per year in interest if you carry the balance — roughly the cost of a domestic flight every month.
Pick a fixed dollar amount you can sustain — even $50–$100 more than the minimum — and stick to it. Consistent fixed payments dramatically reduce total interest and give you a clear payoff date to work toward.
List all cards by APR (highest first) and throw every extra dollar at the top card while paying minimums on the rest. Once the first card is paid off, roll that payment into the next. Saves the most interest mathematically.
