Credit Card Payoff Calculator
Credit card interest can turn a manageable balance into a years-long burden. Enter your balance, APR, and monthly payment to see how long payoff takes and how much interest you will pay.

The True Cost of Credit Card Debt
Credit card interest compounds monthly, which means you pay interest on your interest. A $5,000 balance at 21.99% APR with a $200 monthly payment takes about 32 months to pay off and costs roughly $1,330 in interest. That is a 27% premium on top of what you originally charged.
The math gets worse with smaller payments. Drop that payment to $100 per month and you are looking at over 9 years and more than $5,800 in interest, meaning you pay more in interest than the original balance. This compounding effect is why credit card debt is often called the most expensive form of consumer borrowing.
Fixed Payment vs. Fixed Timeline
This calculator offers two approaches. The fixed payment mode answers the question: if I pay a set amount each month, how long until I am done? The fixed months mode flips it: if I want to be debt-free in a specific number of months, how much do I need to pay each period?
The fixed months approach is powerful for goal setting. Deciding you want to eliminate a balance in 12 months gives you a concrete monthly target. Many people find that having a specific deadline and payment amount makes them more committed than an open-ended payoff plan with no clear end date.
Accelerating Your Payoff
Every extra dollar you put toward the balance reduces the principal faster, which reduces the interest charged in the following month. Even an extra $50 per month can shave months off your payoff timeline and save hundreds in interest. Windfalls like tax refunds or bonuses make excellent lump-sum payments.
Negotiating a lower interest rate directly with your card issuer is another underused strategy. A simple phone call citing your payment history and a competing offer can sometimes knock several percentage points off your APR. Combine a rate reduction with increased payments and you can dramatically compress your payoff schedule.
Frequently Asked Questions
How is credit card interest calculated?
Credit card interest is compounded monthly. The APR is divided by 12 to get the monthly rate, which is then applied to the remaining balance each month. The daily periodic rate (APR divided by 365) is what issuers technically use for daily accrual.
What happens if I only make minimum payments?
Minimum payments, typically 1-3% of the balance, keep you in debt for years and cost thousands in interest. A $5,000 balance at 22% APR with minimum payments can take over 20 years to pay off.
What if my payment does not cover the interest?
If your payment is less than or equal to the monthly interest charge, your balance will never decrease. This calculator will show infinity for the payoff time in that case. You need to pay more than the interest to make progress.
Should I pay off the highest rate card first?
The avalanche method (highest rate first) saves the most money mathematically. The snowball method (smallest balance first) provides psychological wins. Both work as long as you stick with the plan.
Does a balance transfer help?
A 0% balance transfer can save significant interest if you pay off the balance before the promotional period ends. Watch for transfer fees (usually 3-5%) and make sure the math works out in your favor.
