Credit Card Payoff Calculator
Minimum payments keep a credit card alive for decades. Enter your balance, APR and the monthly payment you can afford, and this calculator shows your debt-free date, total interest, and exactly how much you save by paying a fixed amount instead of the minimum.
Debt-Free With Your Fixed Payment
How It Works
A credit card balance shrinks slowly because most of each payment goes to interest, not to the balance. Every month, interest is charged on the full balance at your APR divided by 12 — on a $6,000 balance at 22.36% APR, that is $111.80 of interest in the very first month. Only the part of your payment above that interest reduces what you owe. This calculator walks through the balance month by month, charging interest and subtracting your payment, until the balance reaches zero. That is how the payoff time and total interest are found — no shortcuts, just the same arithmetic your issuer uses.
The comparison that matters is against the minimum payment. Most issuers set the minimum at roughly the month's interest plus 1% of the balance, with a $25 floor — this calculator uses that common formula and says so plainly, because formulas vary by issuer. The trap is that the minimum falls as the balance falls, so you pay less and less each month and the debt drags on. A fixed payment does the opposite: it stays the same, so more and more of it attacks the principal as the interest charge shrinks.
Worked Example
Take a $6,000 balance at 22.36% APR — the Federal Reserve's average for accounts assessed interest in the third quarter of 2026. Paying a fixed $200 a month clears the card in 45 months (3 years and 9 months), with $2,869.63 of interest, for a total paid of $8,869.63. Paying only the minimum instead takes 249 months — 20 years and 9 months — with $10,104.54 of interest and a total paid of $16,104.54. The first minimum payment would be $171.80, which feels easier than $200, but it buys two decades of debt. The fixed payment saves $7,234.92 of interest and 204 months compared with minimum payments on the same card.
Assumptions
- No new purchases are added to the card. Every new charge restarts part of the clock.
- The APR stays fixed. Real card APRs are usually variable and can rise or fall with the prime rate.
- The minimum payment follows the common issuer formula: that month's interest plus 1% of the balance, with a $25 minimum. Your issuer's formula may differ — check your statement.
- Payments are made on time every month. Late fees and penalty APRs are not included.
- Interest is charged monthly on the balance at the start of the month, with no grace period applied.
What this calculator leaves out: balance-transfer offers, 0% introductory periods, fees, penalty rates, and the effect of paying more in some months and less in others. It also assumes a single card — if you carry several, the avalanche method (highest APR first) or the snowball method (smallest balance first) decides the order.
Small increases in the fixed payment pay off far out of proportion, because every extra dollar goes straight to principal. The table below shows the same $6,000 balance at 22.36% APR at four payment levels:
| Fixed monthly payment | Time to pay off | Total interest |
|---|---|---|
| $150 | 75 months (6 yr 3 mo) | $5,113.29 |
| $200 | 45 months (3 yr 9 mo) | $2,869.63 |
| $250 | 33 months (2 yr 9 mo) | $2,027.03 |
| $300 | 26 months (2 yr 2 mo) | $1,577.40 |
| Minimum only | 249 months (20 yr 9 mo) | $10,104.54 |
Going from $150 to $300 a month cuts the payoff time by nearly two-thirds and saves over $3,500 in interest. Even the step from $150 to $200 saves more than $2,200. That is the power of a fixed payment at a high APR: the interest saved is worth far more than the extra cash each month.
How to Use This Calculator
Enter your current card balance and the APR from your statement — the default 22.36% is the national average, but your card's own rate is what matters. Then enter the fixed monthly payment you can realistically sustain. The headline result is your debt-free date with that payment, with the total interest and total paid underneath, and the minimum-payment comparison beside it so you can see what the easy option really costs. If your payment does not even cover the monthly interest, the calculator tells you so: the balance would grow forever, and you need a larger payment or a lower rate.
Use the table and the CSV download to experiment. Try your payment $50 higher and $50 lower, and watch how much the payoff date moves. If you have a 0% balance-transfer offer, run the numbers at 0% APR for the length of the offer to see what the transfer is worth — remembering that the transfer fee, usually 3% to 5% of the balance, is a real cost the calculator does not add.
Tips and Practical Advice
Automate the fixed payment. The minimum-payment trap works because the easy amount is the default — your statement highlights it, and paying it feels like progress. Setting an automatic payment for your fixed amount removes the monthly decision and keeps the payoff on schedule even in a busy month.
If you carry more than one card, pay the minimum on all of them and throw every spare dollar at the highest APR first. That is the avalanche method, and it is the cheapest way out in pure maths. The snowball method — smallest balance first — costs a little more in interest but gives faster wins, which helps some people stick with the plan. Either is far better than minimums on everything.
Finally, call your issuer and ask for a lower APR. It takes one phone call, it often works — especially if you have a good payment history — and even a few points off the rate can save hundreds of dollars. If the answer is no, a balance transfer to a 0% card or a personal loan at a lower rate can do the same job, as long as you do not run the card balance back up.

Frequently Asked Questions
How long does it take to pay off a $6,000 credit card?
At 22.36% APR, a fixed $200 monthly payment clears it in 45 months (3 years 9 months) with $2,869.63 of interest. Paying only the minimum takes 249 months — over 20 years — with $10,104.54 of interest. The payment amount matters more than the balance.
What is the average credit card APR in 2026?
The Federal Reserve's G.19 release for the third quarter of 2026 put the average APR at 22.36% on accounts assessed interest, and 21.19% across all accounts. Your own card's APR is printed on your statement and is the figure to use here.
Is it better to pay a fixed amount or the minimum?
A fixed amount, by a wide margin. Minimum payments shrink as the balance shrinks, stretching the debt over decades. A fixed payment stays constant, so an ever-larger share of it attacks the principal. On the $6,000 example, the fixed $200 payment saves $7,234.92 of interest.
What happens if my payment is less than the monthly interest?
The balance grows instead of shrinking, and the card is never paid off. On a $6,000 balance at 22.36%, the first month's interest alone is $111.80, so any payment below that makes the debt larger. The calculator warns you if your payment is too low.
Should I pay off my credit card before saving?
Usually yes, after keeping a small emergency cushion. Credit card interest at 22% or more is far higher than any safe savings return, so every dollar of card debt you clear is a guaranteed 22% return. Keep enough cash for genuine emergencies, then attack the card.
