How the credit card payoff calculation works
Credit card debt behaves differently from a loan, and the difference is why it is so hard to escape. A loan has a fixed payment and a known end date. A credit card has a minimum payment that shrinks as your balance falls, which stretches repayment out almost indefinitely.
Interest is charged monthly on the balance:
Monthly interest = balance × (APR ÷ 12)
On a $5,000 balance at 22% APR, month one accrues $91.67 in interest. Anything you pay above that reduces the balance; anything below it does not.
Compare three payment strategies on that same $5,000 balance:
- Minimum payment (typically 2% of the balance, about $100 at first): because the minimum falls as the balance does, this takes over 200 months and costs more than $5,700 in interest — you repay more than double what you borrowed.
- Fixed $250 a month: the balance clears in about 24 months with roughly $1,200 in interest.
- Fixed $400 a month: about 14 months and roughly $680 in interest.
Going from $100 to $250 a month — an extra $150 — cuts nearly fifteen years and $4,500 off the debt.
There is a hard floor worth knowing. If your payment is less than the monthly interest, the balance grows no matter how long you pay. On that $5,000 at 22%, any payment under $91.67 means the debt never clears. The calculator above flags this case explicitly rather than showing a nonsense payoff date.
Three things that shorten the timeline:
- Always pay a fixed amount, not the minimum. Locking your payment at today's minimum instead of letting it shrink is the single easiest improvement, and it costs nothing extra this month.
- A balance transfer buys real time. A 0% APR promotional period of 15-21 months means every dollar reduces principal. Factor in the 3-5% transfer fee and make sure the balance clears before the promotional rate ends.
- Rate matters less than payment size. Cutting the APR from 22% to 15% on a $250 monthly payment saves about $300. Raising the payment from $250 to $400 saves about $520. Do both if you can, but the payment is the bigger lever.

Frequently asked questions
Why does paying the minimum take so long?
Minimum payments are usually a percentage of the balance, often around 2%, so the payment shrinks as the balance falls. Combined with high interest, most of each payment covers interest rather than principal. A $5,000 balance at 22% can take over 200 months on minimums and cost more in interest than the original balance.
How is credit card interest calculated?
Most issuers charge interest daily on the average daily balance, using your APR divided by 365. The practical effect is close to charging the balance one twelfth of the APR each month, which is what this calculator models. Carrying any balance also removes the grace period on new purchases.
What happens if my payment is less than the interest?
The balance grows every month and the debt never clears - a situation called negative amortization. On a $5,000 balance at 22% APR the monthly interest is about $92, so any payment below that makes things worse. The calculator flags this rather than producing a misleading payoff date.
Is a balance transfer card worth it?
Often yes, if you can clear most of the balance during the promotional period. A 0% APR window of 15 to 21 months means every dollar reduces principal. Weigh the 3% to 5% transfer fee against the interest you would otherwise pay, and confirm what rate applies to any balance left when the promotion ends.
Should I pay off the highest rate or the smallest balance first?
Paying the highest APR first - the avalanche method - costs the least in total interest. Paying the smallest balance first - the snowball method - clears individual cards sooner and many people find it easier to sustain. The mathematically optimal method only wins if you actually stick to it.
Does carrying a balance help my credit score?
No. That is a persistent myth. Your score benefits from on-time payments and low credit utilization, both of which improve when you pay in full. Carrying a balance only adds interest charges without any scoring benefit.
