Credit Card Minimum Payment Calculator — Payoff Trap
Calculate your credit card's minimum payment using two common issuer formulas, then see how many years paying only the minimum actually takes.
Recalculating this formula every month as your balance declines, it would take 153 months (≈12.8 years) to pay off this balance, and you'd pay $8,605.21 in total interest along the way.
Issuers set their own minimum payment formulas — there is no single federal or Regulation Z-mandated calculation. This tool models the two most commonly cited patterns: "greater of a flat dollar amount or a percentage of the balance, plus that month's interest" and "a percentage of the balance plus interest and fees, itemized." The payoff simulation recalculates the minimum payment from the declining balance every month, the same way a real statement would. Check your card's cardholder agreement for its exact formula before relying on this for a specific payoff date.
Reference Values
Last verified:| Category | Range | What It Means | Status |
|---|---|---|---|
| Flat-dollar minimum floor | $25–$35 | Most issuers guarantee a minimum payment of at least a flat dollar amount even on small balances, most commonly $25 (some cards use $20, $30, or $35). This is the 'flat amount' side of the greater-of formula. | Okay |
| Greater-of percentage of balance | 1%–3% of balance | The percentage side of the greater-of formula — the minimum payment is whichever is larger: the flat-dollar floor, or this percentage of the statement balance. 2% is the most commonly cited figure. | Okay |
| "Percent + interest + fees" percentage | 1% of balance | A separate, common large-issuer pattern (often cited for Chase-style cards): minimum payment = 1% of the balance, plus the interest charged that month, plus any fees — explicitly itemized rather than a single greater-of comparison. | Good |
| Balance below the flat-minimum threshold ★ | Pay full balance | If your statement balance is already less than the flat-dollar floor (e.g. a $20 balance when the floor is $25), the minimum payment is simply the full balance — issuers don't require you to pay more than you owe. | ★ Best |
| Typical late fee if you miss the minimum | $29–$41 | CFPB-tracked ranges for a first missed payment; a second late payment within six billing cycles can trigger a higher fee, often up to $41. Fee amounts are also subject to CFPB rulemaking changes over time. | Poor |
| Typical credit card APR range (used for interest estimates) | 18%–29.99% | The interest portion of a minimum payment formula depends heavily on your card's APR — higher APRs mean a larger share of every minimum payment goes to interest instead of principal. | Poor |
Source: Formula patterns aggregated from NerdWallet 'How Credit Card Issuers Calculate Your Minimum Payment' and CFPB consumer education materials on credit card minimum payments (2026). The CFPB documents that issuers set their own minimum payment formulas — there is no single federal or Regulation Z-mandated calculation — so exact terms vary by card and are disclosed in each cardholder agreement.
Worked Examples
"1% + Interest + Fees" Formula (Large-Issuer Style)
- Balance
- $10,000
- Formula
- 1% of balance + interest + fees
- Interest Charged
- $160
- Fees Charged
- $41
(1% × $10,000) + $160 interest + $41 fee = $100 + $160 + $41 = $301.00. This explicit itemized pattern is commonly cited for large-issuer cards.
"Greater of Flat $ or % of Balance" Formula
- Balance
- $5,000
- Formula
- Greater of $25 or 2% + interest
- APR
- 22%
2% of $5,000 = $100, which beats the $25 flat floor. Monthly interest = $5,000 × (22% ÷ 12) = $91.67. Minimum payment = $100 + $91.67 = $191.67.
Small Balance Below the Flat-Minimum Floor
- Balance
- $20
- Flat Floor
- $25
Since the $20 balance is already below the $25 flat-dollar floor, the minimum payment is simply the full $20 balance — issuers can't require a minimum payment larger than what you actually owe.
The Minimum Payment Trap — With a Dollar Floor
- Balance
- $8,000
- Formula
- Greater of $25 or 2% + interest
- APR
- 24.99%
- Payment plan
- Minimum payments only
Simulated month-by-month, recalculating 2% of the declining balance (with a $25 floor) plus that month's interest each cycle. Total interest paid over the payoff ($7,692.23) is almost as much as the original $8,000 balance.
The Minimum Payment Trap — Percent-Only, No Floor
- Balance
- $10,000
- Formula
- 1% of balance + interest (no dollar floor)
- APR
- 24%
- Payment plan
- Minimum payments only
With no flat-dollar floor, the required paydown shrinks every month right along with the balance (1% of a shrinking number), so the balance approaches zero but never actually reaches it within a realistic simulation window — a textbook illustration of the 'minimum payment trap.'
How to Use This Calculator
- 1
Enter your statement balance and APR
Your current balance and the card's annual percentage rate — both are on your latest statement.
- 2
Choose the minimum payment formula
Pick 'greater of flat $ or % of balance + interest' or the itemized '% of balance + interest + fees' pattern, whichever matches your card's cardholder agreement.
- 3
Fill in the formula's specific numbers
The flat-dollar floor and percentage for the first formula, or the percentage plus the interest and fee amounts shown on your statement for the second.
- 4
Read your minimum payment due
The calculator shows the total minimum payment and how it breaks down into its component parts.
- 5
See the minimum-payment-trap simulation
Below the result, see how many months (or years) it would take to pay off the balance making only the recalculated minimum payment every month, and the total interest that would cost.
What Each Value Means
- Minimum Payment ($)
- The smallest amount an issuer requires you to pay by the due date to keep your account in good standing, calculated using the issuer's own formula — commonly a flat dollar amount, a percentage of the balance, or some combination plus interest and fees.
- Minimum Payment Trap (months / years)
- The slow-payoff effect that happens when a percentage-based minimum payment is recalculated against a shrinking balance every month, causing the required payment (and the pace of payoff) to shrink right along with it — sometimes stretching payoff to decades.
- Total Interest Paid (Minimum-Only) ($)
- The sum of every month's interest charge across the entire simulated payoff period if only the minimum payment is made each month — frequently larger than the original balance itself.
