Credit Card Payoff Calculator

It depends on your balance, APR, and monthly payment. A $5,000 balance at 24% APR takes about 56 months with a fixed $150 monthly payment. Paying only the minimum (typically 2% of the balance or $25) can stretch the same debt over 40+ years, or never pay it off at all if the payment barely covers the monthly interest. Use the payoff planner above to get an exact schedule for your numbers.

The minimum payment trap is what happens when your required payment is so small that almost all of it goes to interest and nearly none reduces your principal. Many cards set the minimum at 2% of the balance or $25, whichever is higher. On a $5,000 balance at 24% APR, the monthly interest alone is $100, exactly equal to the 2% minimum, so the balance never shrinks. Even at lower APRs, minimum-only payments can keep you in debt for decades while you pay several times the original balance in interest.

Credit card interest is calculated monthly using your APR divided by 12. Each month, the issuer charges (balance × APR ÷ 12) in interest, then subtracts your payment. The remaining balance carries forward and accrues interest again the next month — this compounding is why revolving debt grows so fast. This calculator uses the same monthly method, which is a close estimate for most cards.

If you only pay the minimum, three things happen: (1) payoff takes dramatically longer — often decades instead of years; (2) you pay far more total interest, frequently several times the original balance; and (3) if your minimum is below the monthly interest charge, the balance actually grows. The comparison tab above shows exactly how much extra the minimum-only path costs versus fixed payments.

Paying in full each month is always better: you pay zero interest and avoid debt entirely. If you cannot pay in full, pay a fixed amount well above the minimum — even a modest increase (for example, $150 instead of a $25 minimum on a $5,000 balance) can cut years off the payoff time and save thousands in interest. Only ever pay just the minimum as a last resort to avoid a late fee.

At 24% APR with fixed $150 monthly payments, a $5,000 balance costs about $3,322 in total interest and takes roughly 4 years 8 months to clear. With only minimum payments (2% or $25), the same balance can cost far more and take decades. Enter your exact APR and payment in the calculator for a precise figure.

The payoff time for a fixed monthly payment P on balance B at monthly rate r (APR ÷ 12) is: months = −ln(1 − r·B ÷ P) ÷ ln(1 + r). This only works when P is larger than the monthly interest charge (r·B); otherwise the balance never decreases. The payment simulator tab runs this formula for you, or flips it around: enter your target payoff date and it computes the required monthly payment.

Paying the minimum on time does not directly hurt your score the way a missed payment does, but carrying a high balance for years keeps your credit utilization high, which can suppress your score. High utilization on one or more cards is a major scoring factor, so paying balances down faster generally helps your score recover.

A balance transfer is worth it when the interest you save during the promotional period exceeds the transfer fee. For example, moving $8,000 from a 22% APR card to a 0% card for 18 months with a 3% fee ($240) can save roughly $1,900 in interest if you keep making the same payments. It is not worth it if you cannot pay the balance down before the promo ends and the revert APR is high. Use the balance transfer tab to run your exact break-even.

You break even when (interest you would have paid on the old card) minus (interest you pay on the new card) is greater than the transfer fee. The break-even point in months is approximately: fee ÷ (monthly interest saved). With a 3% fee on $8,000 ($240) saving about $147 per month in interest, you break even in under 2 months — everything after that is pure savings.

On a credit card they are effectively the same number expressed differently: the APR (annual percentage rate) is the yearly cost of borrowing, and the monthly interest rate is simply APR ÷ 12. Unlike loans, credit card APRs generally exclude fees from the rate itself, so the APR is the rate applied to your revolving balance each month.

Each month: (1) interest = balance × APR ÷ 12 is added; (2) your payment is subtracted; (3) the new balance carries forward. With a fixed payment P, the balance follows B(n) = B₀(1+r)ⁿ − P·((1+r)ⁿ − 1) ÷ r. Solving B(n) = 0 gives the payoff month count. Declining payments (percent-of-balance or minimum) shrink as the balance shrinks, which is why they take so much longer — the payment gets smaller exactly when you need it to stay large.

The avalanche method — minimums on every card, all extra cash at the highest APR — minimizes total interest and is mathematically optimal. The snowball method — smallest balance first — clears a card fastest and wins on psychology; people stick with it longer. If your APRs differ by 5+ points, the avalanche's savings are hard to ignore; if they're close, take the snowball's momentum. Either beats paying minimums on all cards.

The grace period is the roughly 21–25 day window between your statement closing date and the payment due date, during which new purchases accrue no interest — but only if you paid the previous statement balance in full. Carry any balance into the new cycle and you lose the grace period: new purchases start accruing interest from the transaction date. This is why "I'll pay most of it" still costs interest on everything you bought that month.

The new card charges 0% (or a low) APR on transferred balances for a promotional period — typically 12–21 months — in exchange for a 3–5% transfer fee added to the balance. Run the break-even first: fee ÷ monthly interest saved = months to break even; the balance transfer tab above does this for you. The two classic traps are failing to pay the balance off before the revert APR (often 20%+) kicks in, and making new purchases on the transfer card — they usually get no grace period and accrue interest immediately.

Utilization — your balances divided by your total credit limits — is about 30% of a FICO score, second only to payment history. Both per-card and overall utilization count. Under 30% is the common guideline and under 10% is ideal; paying a $5,000 balance down from a $10,000 limit (50% utilization) to $2,000 (20%) can lift a score materially within a statement cycle or two, since utilization has no memory — only the latest reported ratio matters.

Yes, and it's worse on every dimension: cash advances usually carry a higher APR than purchases, accrue interest immediately with no grace period, and add a 3–5% upfront fee (often with a $10 minimum). A $1,000 cash advance at 29.99% with a 5% fee costs $50 on day one plus about $0.82 per day in interest. It's among the most expensive ways to borrow — avoid it for anything short of a genuine emergency.
