Credit Card Payoff Calculator
Credit card debt behaves differently from a loan because you choose the payment. This calculator shows how long a balance takes to clear at a fixed monthly amount, and how much of that amount is being swallowed by interest before it touches the balance.

How the credit card payoff calculator works
Each month, interest = balance × APR ÷ 12. Whatever remains of your payment reduces the balance: new balance = balance + interest − payment.
The calculation loops until the balance reaches zero, which is why the payoff time responds so sharply to small increases in payment.
Minimum payments are typically 1–3% of the balance plus interest. Because the minimum shrinks as the balance shrinks, it stretches the payoff over years.
Worked example: 5,000 balance at 22% APR
- Monthly interest rate: 22 ÷ 12 = 1.833%. First month's interest = 5,000 × 0.01833 = 91.67.
- Paying 150: only 58.33 reduces the balance. Clearing the debt takes about 47 months and roughly 2,000 in interest.
- Paying 250: 158.33 hits the balance in month one, and the debt clears in about 24 months for roughly 1,000 in interest.
- An extra 100 a month halves both the time and the interest.
Common mistakes to avoid
Paying the minimum and assuming progress
At a 2% minimum on a 22% card, most of the payment is interest and fees. A 5,000 balance can take well over a decade to clear this way.
Believing new purchases share the promo rate
Cards apply promotional 0% terms to specific balances. New spending often accrues at the standard purchase APR immediately, and payments may be allocated to the cheapest balance first.
Overlooking the grace period
Carrying any balance usually forfeits the interest-free window on new purchases, so the card starts charging from the transaction date.
Frequently asked questions
How long will it take to pay off my credit card?
It depends entirely on the fixed amount you commit to. Enter a payment above the minimum and hold it steady — the payoff time falls much faster than the payment rises.
Should I use the snowball or avalanche method?
Avalanche (highest APR first) costs less mathematically. Snowball (smallest balance first) clears accounts sooner and keeps motivation up. The gap is usually small, so the method you will actually finish wins.
Does a balance transfer really help?
It can, if you clear the balance inside the 0% window. Factor in the 3–5% transfer fee and check what rate applies afterwards.
Why did my balance grow even though I paid?
Interest is added before your payment is applied, and cash advances or fees can exceed a small payment. If the payment is below the monthly interest, the balance rises.
Is it better to pay down cards or build savings first?
A small emergency buffer prevents new card debt, so most planners build one month of essentials, then attack the cards, then finish the fund.

The minimum payment is designed to shrink as your balance shrinks. That single feature is what turns a modest balance into a decade of payments.
