Credit Cards: What You Owe and How Fast You Can Pay It Off
A credit card balance isn't a fixed-term loan — it's a revolving line of credit that keeps charging interest on whatever you still owe, for as long as you owe it. This calculator covers both sides of that coin: what a given monthly payment actually costs you today, and how long it takes to reach a zero balance if you stick with it.
Revolving, Not Fixed
Unlike an installment loan, a credit card has no set term. Interest recalculates every month against whatever balance remains, which is why the same payment can take wildly different amounts of time to clear depending on your APR.
Payment vs. Payoff Speed
Small increases in your monthly payment can cut months, even years, off your payoff timeline. Because interest is charged on a shrinking balance, extra dollars paid early do disproportionately more work than dollars paid late.
The Minimum Payment Trap
Issuer-set minimum payments are usually a small percentage of your balance, so as the balance shrinks so does the minimum — which means the payoff drags on for decades and interest quietly compounds the whole time.
APR Is Everything
Credit card APRs are typically far higher than mortgage or auto loan rates. A few points of APR difference between cards can mean thousands of dollars in extra interest on the same balance and payment.
Worked Example
Suppose you carry a $5,000 balance at 22.99% APR and pay a fixed $200 per month:
- Time to pay off: 35 months (just under 3 years).
- Total interest paid: approximately $1,871.08.
- Total paid overall: approximately $6,871.08.
Now compare that to paying only a typical 2% minimum (with a $25 floor): the balance would still be growing interest more than a century from now — over 150 years and roughly $88,000 in interest before it's gone, which this calculator's practical 50-year cap simply reports as "Never."
$200/mo vs. Minimum Only
- $200/mo payoff time: 35 months
- $200/mo total interest: $1,871.08
- Minimum-only total interest: ~$88,282 (150+ years)
Why "Just the Minimum" Is So Expensive
Minimum payments exist to keep an account in good standing, not to help you pay off the debt efficiently. Most issuers set the minimum as a small percentage of your balance (commonly 1-3%) with a dollar floor. As your balance falls, so does the required minimum — which means the payoff schedule stretches out almost indefinitely while interest keeps compounding on whatever remains.
A note on this calculator: the forward simulation iterates your balance month by month using your entered APR and fixed payment, capping at 600 months (50 years) as a practical ceiling — if your payment doesn't clear the balance within that window (or doesn't even cover the interest accruing on day one), the calculator flags it instead of looping forever.
Key Takeaways
- Payment Must Beat Interest: Your monthly payment has to exceed the interest accruing on your balance, or you'll never make progress — this calculator checks for that before running the numbers.
- Small Increases, Big Impact: Bumping your fixed payment even modestly can shave years off a high-APR balance.
- Minimum-Only Is a Trap: Paying only the issuer's minimum can turn a five-figure balance into a lifetime of interest payments.
