💳Credit Card Payoff Calculator: Debt-Free Date & Interest

How credit card interest works

Credit cards charge interest daily on your average balance. The APR is divided by 365 to get a daily rate, applied to the balance each day, and added up at the end of the billing cycle. On a $6,500 balance at 24.99% APR, that's about $135 a month in interest before you've paid a cent of principal. This calculator uses monthly compounding (APR ÷ 12), which lands within a dollar or two of your statement.

Because interest is charged on the remaining balance, every extra dollar you pay this month reduces every future interest charge. That's why increasing a $200 payment to $300 doesn't just shorten the payoff by a third, it shortens it by more than that.

Why minimum payments are a trap

Most issuers set the minimum at 1%–3% of the balance plus that month's interest, with a floor around $25–$35. Since the minimum shrinks as the balance shrinks, the payoff stretches over decades. A $6,500 balance at 24.99% paid at 2% + interest takes over 20 years and costs more in interest than the original debt. The calculator shows this scenario next to yours, so you can see what a fixed payment saves.

The single most effective move: fix your payment at today's minimum (or higher) and don't let it drop as the balance falls.

Strategies to pay it off faster

• Balance transfer: move the balance to a 0% intro APR card (usually 12–21 months). The 3%–5% transfer fee is almost always cheaper than months of 24% interest, *if* you pay it off before the promo ends.
• Debt consolidation loan: a personal loan at 8%–15% replaces card debt at 22%+ with a fixed schedule. Run it in the loan calculator.
• Ask for a lower rate: a five-minute call to the issuer succeeds surprisingly often for customers with on-time history.
• Pay twice a month: splitting your payment reduces the average daily balance, trimming interest slightly and making it harder to spend the money elsewhere.
• Multiple cards? Use the debt payoff planner to order them by avalanche or snowball.

Should you save or pay off cards first?

Keep a small emergency cushion ($1,000 or one month of essentials) so a surprise doesn't go straight back on the card, then throw everything at the card. No savings account pays anything close to 24%, so every dollar toward the card is a guaranteed 24% return.
