Uses the monthly approximation of daily card interest (APR ÷ 12 on the balance). Real statements accrue daily on your average daily balance, so actual figures can differ by a few dollars. New purchases on a card carrying a balance typically lose their grace period and accrue interest immediately.
Credit card debt is the most expensive way most households ever borrow, and the minimum-payment structure is engineered to keep it that way. Enter your balance, APR and payment to see your real payoff date — and what the same balance costs at minimum payment. The second number is the one that should bother you.
Card interest is simple in structure and brutal in effect: a daily rate (APR ÷ 365) applied to your average daily balance, charged monthly. There's no amortization schedule pushing you toward zero the way a car loan has. The payment decides everything. That's why the most useful number on this page isn't the payoff date — it's the gap between what you pay and what the interest alone eats.
n = −ln(1 − rB/P) ÷ ln(1 + r)- n
- months to pay off
- r
- monthly rate (APR ÷ 12)
- B
- balance
- P
- monthly payment
One condition governs the formula: P must exceed the first month's interest (rB). If it does not, the balance grows no matter how many payments you make — the calculator tells you so explicitly rather than returning a nonsense date.
Worked example: $5,000 at 24.99% APR
At 24.99%, the first month's interest alone is about $104. A $150 payment retires the balance in 58 months — nearly five years — at a total interest cost of about $3,600. Pay $200 instead and the payoff drops to 32 months with roughly $1,860 in interest. The extra $50 a month saved about $1,750 and two and a half years. That marginal comparison is the whole game.
| Payment | Months to payoff | Total interest | Payoff date from Oct 2026 |
|---|---|---|---|
| $150 | 58 | ≈$3,600 | mid-2031 |
| $200 | 32 | ≈$1,860 | mid-2029 |
| $300 | 19 | ≈$1,010 | mid-2028 |
Monthly approximation of daily compounding; actual statements differ by a few dollars.
The minimum payment trap, quantified
Minimums are typically 1%–3% of the balance or a small floor, whichever is larger. The structure is the trap: the payment shrinks as the balance shrinks, stretching the tail indefinitely. On the $5,000 example, a 2% minimum is $100 on day one — below the $104 monthly interest, so the balance actually grows before the floor takes over. Regulators force card issuers to warn about exactly this on every statement. Now you've seen why, in numbers.
| Strategy | Months | Total interest |
|---|---|---|
| Fixed $150 | 58 | ≈$3,600 |
| 2% minimum | 100+ | ≈$6,900+ |
Minimum-payment outcome simulated with declining payments; '100+' reflects the floor-dominated tail.
Paying it down faster: what actually moves the number
- Fix the payment, not the balance percentage — a constant dollar amount accelerates automatically as interest shrinks
- Attack the highest APR first (avalanche) if you carry multiple cards — the math is unambiguous
- Consider a 0% balance transfer if you can clear it inside the promo window — but price the 3%–5% fee and know the end date
- Stop adding to the balance — new purchases often lose their grace period while a balance exists, accruing interest from day one
- Redirect windfalls to the balance once — a $1,000 tax refund applied here saves more than it ever earns in savings

Frequently asked questions
How long will it take to pay off my credit card?
It depends on the split between your payment and the monthly interest. Interest accrues daily on most cards at APR ÷ 365, charged monthly. If your payment barely exceeds the interest, the balance crawls; if it is below the interest, it never falls at all. The calculator solves the exact month count.
Why does paying only the minimum take so long?
Minimums are usually 1%–3% of the balance, so the payment shrinks as the balance shrinks — and most of each early payment is interest. On a $5,000 card at 25% APR, minimum payments can take well over a decade and cost more in interest than the original purchases.
How is the payoff date calculated?
With the amortization formula rearranged for the number of payments: n = −ln(1 − rB/P) ÷ ln(1 + r), where r is the monthly rate, B the balance and P the payment. If P is at or below the first month's interest (rB), no solution exists — the balance grows.
What payment clears my balance fastest?
Any dollar above interest goes straight to principal, so the fastest realistic payoff is simply the largest payment your budget survives. The useful exercise is marginal: see what moving from $150 to $200 a month does — on a $5,000 balance at 25%, it cuts roughly a year and hundreds in interest.
Should I use a balance transfer card?
If you can qualify for a 0% promotional APR and can commit to paying the balance off inside the window, a transfer can stop the interest clock entirely. Factor the typical 3%–5% transfer fee, and know that the promo rate ends — often jumping straight to the standard APR.
Does this account for daily compounding?
The calculator uses the standard monthly approximation (APR ÷ 12), which tracks card statements closely for planning. Card issuers charge interest daily on the average daily balance, so actual figures can differ by a few dollars a month. Statement copies show the exact interest charged.
Should I pay off my card or save first?
Almost always the card, after a starter emergency fund. Eliminating a 25% APR balance is a guaranteed, tax-free 25% return — nothing in a savings account compares. The exception is building a small cash buffer so the next car repair doesn't go back on the card.
What is a debt avalanche versus debt snowball?
Avalanche pays the highest-APR debt first — mathematically optimal. Snowball pays the smallest balance first — psychologically motivating, because an early win sustains the habit. The interest difference is usually modest; pick the one you'll actually stick to.
