How This Calculator Works
Enter the card balance, its APR, and the fixed amount you intend to pay every month. The calculator charges interest on the balance each month, subtracts your payment, and repeats until the balance reaches zero — counting the months and adding up the interest. It also warns you when a payment is too small to ever clear the debt.
The Formula
Debt Payoff Time
B = balance, P = fixed monthly payment, r = monthly rate (APR ÷ 12), n = months to clear
Worked Example
A $5,000 balance at 21.5% APR paid down at $200 a month clears in 34 months. Along the way you pay about $1,691 in interest, so the $5,000 borrowed costs roughly $6,691 by the time the card is paid off.
Key Insight
Credit card APRs are high enough that a small payment barely dents the balance. Paying even a little more each month cuts both the time and the interest dramatically, because a larger share of every payment goes to principal.
The minimum payment trap: 30+ years to pay off
Credit card minimum payments are designed for the card issuer's profit, not the cardholder's escape. Typical minimum: 1-3% of balance + interest, or $25 floor — whichever is higher. On a $10,000 balance at 22% APR with 2% minimum payment, payoff takes 31 years and costs $20,500 in interest — more than 2× the original balance.
Worked comparison on the same $10,000 / 22% APR balance: Minimum payment only ($200 start): 31 years, $20,500 interest. Doubling minimum ($400/month): 4 years, $4,500 interest. Aggressive payoff ($600/month): 1.8 years, $2,000 interest. The difference between minimum and aggressive payoff: $18,500 in interest saved — a 'salary' you give yourself by paying faster.
Why this works: credit card interest compounds DAILY. Each day you carry a balance, the issuer charges (annual rate / 365) × balance. Today's interest is added to tomorrow's principal. Even small extra principal payments substantially reduce total interest because they shrink the daily-compounding base.
Avalanche vs Snowball: math vs psychology
Two main strategies for multiple credit card debts. AVALANCHE: pay minimums on all, throw all extra cash at the HIGHEST INTEREST RATE card first. Mathematically optimal — minimizes total interest paid. Best for analytical people who can stay motivated by numbers.
SNOWBALL: pay minimums on all, throw all extra cash at the SMALLEST BALANCE card first. Mathematically slightly worse, but psychologically powerful — quick wins (paying off small cards in months) build momentum. Research (Olson, Northwestern) shows snowball users have HIGHER completion rates than avalanche users for credit card debt elimination.
Hybrid that often works: 'Avalanche with first quick win.' Pay off your smallest card first for psychological momentum (1-2 months), then switch to highest-interest cards. This captures snowball's motivation boost without sacrificing too much interest savings. The right method is the one you'll actually finish — completion rate beats theoretical optimality.
Balance transfer 0% APR: the math that works and the trap that doesn't
0% APR balance transfer offers (12-21 months) can save massive interest if used correctly. Math: transfer $10,000 from 22% APR card to 0% card with 12-month promotional period and 3% transfer fee. Transfer fee: $300. If you pay off in 12 months: total cost $300 (vs $1,500-2,000 interest on the old card). Net savings: $1,200-1,700.
Critical execution: actually pay off the balance during the promotional period. If you don't, the post-promotional APR (often 18-25%) kicks in on the REMAINING balance — sometimes RETROACTIVELY for the entire 12 months ('deferred interest' clauses). Read fine print: 'No interest if paid in full by [date]' = retroactive interest if not. 'Special promotional APR' usually means only the remaining balance gets the high rate.
Common balance transfer mistakes that erase savings: (1) continuing to spend on the OLD card (creates new debt at high APR alongside the transferred balance), (2) missing a single payment (often voids the 0% offer instantly), (3) not paying enough to clear by promotional end (high APR kicks in), (4) opening multiple new cards for transfers (damages credit score, complicates payment management). The 0% offer is a tool — useful when used precisely, dangerous when used carelessly.
Payoff time and interest by monthly payment ($10,000 balance, 22% APR)
How dramatically different payoff times and total costs change with payment amount. Even small payment increases over minimum produce large interest savings.
| Monthly payment | Payoff time | Total interest paid | Total cost |
|---|---|---|---|
| $200 (~minimum) | ~31 years | $20,500 | $30,500 |
| $300 | ~5 years | $5,800 | $15,800 |
| $400 | ~3 years 4 months | $3,700 | $13,700 |
| $500 | ~2 years 6 months | $2,800 | $12,800 |
| $1,000 | ~1 year 1 month | $1,200 | $11,200 |
Each extra $100/month dramatically reduces both payoff time and total interest. Doubling the minimum (from $200 to $400) shortens payoff from 31 years to 3 years and saves $16,800 in interest. The math is brutally clear: minimum payments are a wealth-destroying trap.
Frequently Asked Questions
Why does paying the minimum take so long?
The minimum payment is set low, often close to the monthly interest. With little left to reduce principal, the balance falls slowly and interest keeps accruing on a barely shrinking amount.
What if my payment is below the interest?
Then the balance grows rather than falls and the card is never paid off. The calculator flags this and asks you to raise the payment above the monthly interest charge.
Does this assume no new purchases?
Yes. The calculation assumes you stop adding to the card. New charges restart interest on a higher balance and push the payoff date further out.
How much should I pay each month?
As much as your budget allows above the minimum. Try larger monthly payments in the calculator to see how sharply the months and the total interest fall.
Is the APR fixed?
Most credit card APRs are variable and move with the prime rate. The calculator uses one fixed APR, so re-run it if your card's rate changes.

Methodology & Review
The payoff is simulated month by month: interest is charged on the balance, the fixed payment is deducted, and the months are counted until the balance clears. New purchases and fee changes are not modeled.
