Credit Card Payoff Calculator
The minimum payment isn't designed to help you pay off a balance. It's designed to keep you in it longer. On a $5,000 balance at 22% APR, a minimum payment that barely clears $125 a month can drag the payoff out to nearly three years and cost you over $1,300 in interest — none of which reduces what you originally owed. This calculator shows you the real timeline and real interest cost of any fixed monthly payment, so you can make an informed decision rather than a default one. Enter your balance, your card's APR, and what you plan to pay monthly.
How It Works
Credit card interest is calculated monthly on whatever balance remains. Each payment first covers the interest that accrued that month; the rest reduces principal. When your payment is only slightly above the minimum, the interest portion eats most of it — which is why balances can feel like they barely move.
This calculator iterates month by month through that math until the balance reaches zero. It uses simplified monthly accrual (APR ÷ 12), which is a close approximation to most cards' actual daily compounding method. The payoff month count and total interest figure give you a real basis for deciding whether to pay more, pay less, or consolidate.
Worked Examples
Example 1 — the slow road. Balance: $5,000. APR: 22%. Payment: $125/month. Payoff: 62 months (over 5 years). Total interest: ~$2,744. You pay more in interest than half the original balance.
Example 2 — accelerated payoff. Same $5,000 at 22%. Payment raised to $200/month. Payoff: 32 months. Total interest: ~$1,349. Paying $75 more per month saves $1,395 in interest and 30 months.
Example 3 — smaller balance. Balance: $2,500. APR: 19%. Payment: $100/month. Payoff: 30 months. Total interest: ~$488.
When to Use This Calculator
Run this calculator before you decide what to pay each month — not after:
- To see the true cost of the minimum — the total-interest figure is the number that motivates change, not the balance.
- To test a higher payment — try several payment amounts to find the threshold where payoff shortens meaningfully. Often adding $50–$75 makes a dramatic difference.
- When comparing payoff to a personal loan — a personal loan at a lower rate with a fixed term can beat years of credit card interest. Run this first, then compare with the Personal Loan Calculator.
- To prioritize which card to pay off first — if you have multiple cards, run each and focus on whichever combination saves the most total interest.
Frequently Asked Questions
Why does the minimum payment barely reduce my balance?
Because credit card interest is calculated on the outstanding balance every month. If your balance is $5,000 at 22% APR, you're accruing about $91.67 in interest per month. A $125 minimum payment leaves only $33.33 to reduce the actual balance. That's not a bug — it's how revolving credit is structured.
What happens if my payment is less than the monthly interest?
Your balance grows every month even though you're making payments. This is called negative amortization. If the calculator tells you your payment is too low, it means you're not making forward progress — the balance is increasing. You need to raise your payment above that month's interest charge to start reducing the principal.
Would consolidating onto a personal loan actually help?
Often yes. Personal loans typically carry lower APRs than credit cards, and they have a fixed end date — something revolving credit doesn't guarantee. Use the Personal Loan Calculator to estimate a monthly payment on the same balance at a lower rate, then compare total interest paid. The difference can be substantial.
