| Plan | Monthly payment | Time to pay off | Total interest |
|---|---|---|---|
| Your plan | $200.00 | 2 years, 10 months | $1,749.88 |
| Minimum payment only | $100.00 (starting) | 50+ years | Does not pay off |
Your plan pays this balance off in 2 years, 10 months. More than 50 years — this balance may never be paid off at the minimum, so it never finishes within the modeled horizon.
How credit card payoff time is calculated
With a fixed monthly payment and a constant APR, the number of months to pay off a revolving balance follows the standard amortization formula for months to payoff, where each payment first covers the month's interest and the remainder reduces principal.
n = −ln(1 − rB / P) / ln(1 + r)- n
- Months to payoff
- B
- Starting balance
- P
- Fixed monthly payment
- r
- Monthly periodic rate (APR ÷ 12)
The "minimum payment only" comparison models a more realistic minimum: each month's payment is recalculated as a percent of the current balance (the minimum payment percent set in advanced assumptions), floored at $25, the way many card issuers set minimum payments. Because that payment shrinks as the balance shrinks, payoff can take decades — or never happen within the 50-year model horizon used here.
$5,000 balance at 22% APR, $200 per month
A $5,000 balance at a 22% APR paid down with a fixed $200 monthly payment is debt-free in 34 months (2 years, 10 months), paying $1,749.88 in total interest and $6,749.88 in total payments.
Paying only the minimum on that same balance starts at about $100 (2% of $5,000) and shrinks every month as the balance falls. At that declining pace, the balance never pays off within the calculator's 50-year model horizon — a striking illustration of why minimum payments alone can trap a balance in interest charges indefinitely.
What this calculator assumes
- The entered APR stays fixed for the full payoff period.
- No new charges are added to the balance after the starting point.
- The minimum-payment scenario recalculates the payment as a percent of the current balance each month, floored at $25.
- No annual fees, late fees, or promotional-rate periods are modeled.
- Money values are rounded to the nearest cent for display.
Understanding the Credit Card Payoff Calculator
A credit card is a revolving line of credit, and its interest is calculated in a way that quietly works against you: the APR is applied to your balance every single day, and the interest itself becomes part of the balance the next day. This calculator turns that compounding into a clear timeline — how many months a fixed monthly payment needs to erase your balance, and how much of your money goes to interest along the way.
Its most useful feature is the comparison. Alongside your chosen payment, it models what happens if you pay only the issuer's minimum, so you can see in dollars and years the difference between a deliberate payoff plan and the path the card is designed to keep you on.
Who this calculator is for
- Cardholders carrying a balancewho want a realistic date for being debt-free instead of a vague 'someday'.
- Anyone stuck on minimum paymentswho suspects the minimum is barely moving the balance and wants to see the real cost.
- People budgeting a fixed paymenttesting how much faster $50 or $100 more each month clears the debt.
- Balance-transfer and consolidation shoppersestablishing a baseline payoff cost before comparing a 0% offer or a personal loan.
- Households rebuilding after overspendingwho need a concrete plan to point at and stick to month after month.
Why it matters
- It exposes the minimum-payment trap in real numbers — because the minimum is recalculated as a small percent of a shrinking balance, most of each payment goes to interest and payoff can stretch for decades.
- It shows the payoff date, so an open-ended debt becomes a finite goal you can plan a budget around.
- It quantifies total interest, turning APR from an abstract percentage into a dollar figure you actually pay.
- It rewards small increases — nudging the monthly payment up and re-running it reveals how much time and interest even a modest boost saves.
- It gives you a defensible baseline for deciding whether a balance transfer, consolidation loan, or hardship program is worth pursuing.
How to use this calculator
- Enter your current balance — the full amount you owe on the card today, not the minimum due.
- Enter the APR from your statement. US and Canadian cards commonly run in the high teens to high twenties, and even a few points changes the outcome noticeably.
- Set the fixed monthly payment you intend to make every month, regardless of what the minimum happens to be.
- Under advanced assumptions, adjust the minimum-payment percent (often 1–3% of the balance) if your issuer uses a different figure, so the minimum-only comparison matches your card.
- Read the payoff time and total interest, then compare them against the minimum-only scenario and the full month-by-month schedule.
How to read your result
The headline is the number of months to payoff and the total interest you will pay getting there. Read them together: a payment that clears the balance quickly and one that drags it out can differ by thousands of dollars in interest even though the balance started identical. The month-by-month schedule shows how each early payment is mostly interest and how the principal portion grows as the balance falls.
The minimum-only comparison is the number to sit with. If it shows payoff taking decades — or never completing within the model's horizon — that is not a quirk of the math; it is how minimum payments behave on a high-APR balance. Any fixed payment above the minimum breaks that cycle, and the gap between the two scenarios is the concrete payoff for committing to a set amount.
- New purchases break the plan. The model assumes you stop charging to the card; every new swipe resets progress and extends the payoff date.
- The APR is treated as fixed, but variable-rate cards move with the prime rate, and a missed payment can trigger a much higher penalty APR.
- Minimum-payment formulas vary by issuer — some add that month's interest and fees on top of a percentage — so your real minimum may differ from the model's estimate.
- Fees aren't modeled. Annual fees, late fees, and over-limit fees add to the balance and the interest it generates.
- Paying by the statement due date matters for interest: carrying any balance generally forfeits the grace period, so new purchases start accruing interest immediately.
- Pay a fixed dollar amount, not the minimum. A steady payment keeps chipping at principal while the minimum shrinks alongside the balance and stalls.
- If you hold several cards, direct any extra toward the highest-APR one first (the avalanche method) while paying minimums on the rest — it costs the least interest overall.
- Redirect the freed-up payment. Once the card is paid off, roll what you were paying into savings or the next debt instead of absorbing it back into spending.
Frequently asked questions
How is credit card interest actually charged?
Most issuers use the average daily balance method. Your APR is divided into a daily periodic rate, that rate is applied to your balance each day, and the day's interest is added to the balance — so interest compounds daily. This calculator models it on a monthly basis, which closely approximates the same outcome for a fixed payment.
Why does paying only the minimum take so long?
The minimum is usually a small percent of the current balance (often 1–3%), so as the balance falls the required payment falls too. That keeps a large share of every payment going to interest rather than principal. On a high-APR balance, minimum-only payoff can stretch for decades.
Should I use the avalanche or snowball method with multiple cards?
The avalanche method (paying extra toward the highest APR first) costs the least total interest. The snowball method (smallest balance first) can feel more motivating because you clear accounts sooner. For a single card the distinction doesn't apply; for several, this tool helps you baseline each one.
Will paying off my card help my credit score?
Lowering your balance reduces your credit utilization — the share of your available credit you're using — which is a major scoring factor, so paying down a card generally helps. Keeping the account open after payoff preserves your available credit and account age, which can help further.
Is a balance transfer or consolidation loan a better option?
It depends on the numbers. A 0% balance transfer or a lower-rate consolidation loan can cut interest, but transfer fees, loan origination fees, and post-promo rates matter. Use this calculator to find your baseline interest cost, then compare it against a specific offer before deciding.
