Credit Card Minimum Payment Payoff Calculator (2026)

How the minimum payment formula actually works

Three pieces drive the minimum payment number you see on your statement:

1. The percentage of balance. Most issuers use 1% of the principal balance. A few (notably Chase and American Express) use 2% on certain card lines. The cardholder agreement spells out the exact percentage; this is publicly disclosed under Regulation Z.
2. Plus interest and fees. Add the accrued interest for the cycle (the APR divided by 365, multiplied by the average daily balance, multiplied by cycle days) and any late fees or over-limit fees.
3. Floor. If the calculated minimum is below $25 to $35 (issuer-specific), the minimum becomes the floor amount. This is why a $50 balance still triggers a $25 or $35 minimum.

On a $5,000 balance at 22.30% APR with no fees: 1% of $5,000 is $50, plus roughly $93 in interest, equals $143. That $143 starts as 65% interest and 35% principal. As the balance falls, the interest portion falls faster than the principal portion, but the total minimum payment also falls, which is what produces the long tail.

Why minimum-only stretches to 196 months on a $5,000 balance

The declining minimum payment formula creates an asymptotic curve: the payment chases the interest accrual downward, and the principal reduction never accelerates. Modeling the full trajectory cycle by cycle:

• Cycle 1: balance $5,000, minimum $143, interest $93, principal reduction $50, new balance $4,950
• Cycle 12: balance $4,348, minimum $124, interest $81, principal reduction $43, new balance $4,305
• Cycle 60: balance $2,510, minimum $72, interest $47, principal reduction $25, new balance $2,485
• Cycle 120: balance $1,225, minimum $35 (floor active), interest $23, principal reduction $12
• Cycle 180: balance $440, minimum $35 (floor), interest $8, principal reduction $27
• Cycle 196: balance clears

The total interest paid: $7,184. The total cash outflow: $12,184 on an original $5,000 borrowed. This is the CFPB-documented outcome that the CARD Act 36-month rule was designed to make visible.

What the CARD Act 36-month disclosure actually says

Section 1637(b)(11) of Title 15 U.S. Code requires every monthly credit card statement to display:

1. The number of months to pay off the current balance making only minimum payments.
2. The total cost (principal plus interest) under minimum-only payment.
3. The monthly payment that would clear the balance in 36 months.
4. The total cost under the 36-month accelerated plan.

The disclosure has been mandatory since February 2010 and appears on every statement in a standardized box. The pillar calculator at ccpayoffcalc.com matches the methodology issuers use for this disclosure, so the months-to-payoff figure on your statement should match what the calculator returns when you set “minimum only” mode.

How to run minimum-only on the pillar tool

The pillar calculator supports minimum-only mode. To replicate your statement’s CARD Act disclosure:

1. Enter your current statement balance.
2. Enter your APR (purchase APR, not cash-advance or penalty APR unless those are active).
3. Set payment mode to “minimum only” and choose the minimum formula (1% + interest, 2% + interest, or specify a custom formula from your cardholder agreement).
4. The output shows months to payoff and total interest. Compare this directly to your statement’s disclosure box.

For the side-by-side comparison most readers want, run minimum-only and any fixed payment in adjacent tabs. The dollar savings between the two are usually large enough to justify the discipline.

Worked minimum-only scenario by balance

At 22.30% APR with the 1% + interest minimum formula:

The non-linear scaling is the most counterintuitive aspect of the minimum-payment trap. A 5x increase in starting balance produces a 1.7x increase in months-to-payoff but a 9x increase in total interest. Larger balances pay disproportionately more interest under minimum-only.

The “save by switching to fixed” delta

For each starting balance, the savings from switching to a fixed payment equal to roughly 2x the initial minimum:

Switching from minimum-only to a fixed payment at twice the starting minimum produces interest savings of $390 to $29,095 depending on balance. This is the single largest improvement available to a cardholder paying only the minimum.

The smallest possible upgrade from minimum-only

If you are currently paying only the minimum and feel unable to add much, the smallest useful upgrade is: pay your starting-cycle minimum, every month, as a fixed dollar amount, even after the formula minimum drops.

On a $5,000 balance starting at $143 minimum, holding $143 fixed (rather than letting it decline) produces:

• Months to payoff: 56 (vs 196 minimum-only)
• Total interest: $3,008 (vs $7,184 minimum-only)
• Savings: 140 months and $4,176

The cash outflow is identical to the minimum in cycle 1; the savings come entirely from refusing to let the payment shrink. This is the lowest-friction upgrade available and captures roughly 60% of the available interest savings. See round up payment calculator for how to formalize this as a behavioral commitment.

When the minimum is genuinely all you can afford

If the contractual minimum is the absolute ceiling of your monthly capacity, three options reduce the burden without paying more:

1. Hardship program. Most issuers (Chase, Citi, Capital One, Discover, American Express) offer 6-to-12-month hardship programs that reduce the APR to 6% to 10%, waive late fees, and sometimes reduce the minimum payment. The hardship program is the structural response to short-term income disruption. See what to do if you cannot afford credit card minimum payment.
2. Non-profit credit counseling and debt management plan. NFCC-member agencies negotiate APRs down to a 6% to 10% range and consolidate all minimum payments into one monthly payment. The plan typically lasts 3 to 5 years. See debt management plan calculator.
3. Balance transfer to 0% intro APR. If your FICO is 670+, transferring high-APR balances to a 0% intro card eliminates interest accrual for 15 to 21 months. The 3% to 5% transfer fee is usually recouped within 2 to 3 months of saved interest. See 0 APR balance transfer calculator.

Minimum payments and credit score effects

Paying the minimum on time keeps your account in good standing with respect to payment history, which is 35% of the FICO score per FICO’s published score weighting. However, the high balance maintained under minimum-only payment produces high credit utilization (balance divided by credit limit), which is 30% of the FICO score. A $5,000 balance on a $6,000 limit card produces 83% utilization, which suppresses FICO by 60 to 100 points compared to a paid-down balance.

Paying above the minimum reduces utilization faster, which directly improves the score. Most cardholders who switch from minimum-only to fixed-double-minimum see FICO improvements of 30 to 70 points within 6 to 12 months.

Minimum payments during a 0% intro APR window

During a 0% intro APR period (typical on balance-transfer cards), the minimum payment formula still applies, but the interest portion is zero. So the minimum becomes effectively just 1% of the balance (or the $25 to $35 floor, whichever is greater). Paying only the minimum during a 0% intro window does not accrue interest, but it almost guarantees the balance survives past the promo deadline.

Once the promo ends, the remaining balance reverts to the regular APR (typically 22% to 28% on retail balance-transfer cards). The CFPB documents that approximately 40% of balance-transfer users carry a balance past the intro period, which converts the transfer from “interest-free” to “delayed interest at standard rates.” See what happens after 0 APR ends for the post-promo math.

Frequently asked questions

What is the minimum payment formula on most credit cards?

Most issuers calculate the minimum as 1% of the principal balance plus accrued interest and any fees, with a floor of $25 to $35. A few issuers (notably Chase and American Express) use 2% of the balance. Your cardholder agreement spells out the exact formula. On a $5,000 balance at 22.30% APR, the typical minimum is $143.

How long does paying only the minimum actually take?

On a $5,000 balance at 22.30% APR, paying only the contractual minimum (which declines as the balance falls) takes approximately 196 months (16.3 years) and costs $7,184 in total interest. The CARD Act of 2009 requires issuers to disclose this figure on every monthly statement so cardholders can see the trap clearly.

Why is minimum-only payoff so much longer than 36 months?

The 36-month figure on your statement assumes a fixed payment held constant for 3 years. The actual minimum payment formula declines as the balance falls (1% of a shrinking balance plus shrinking interest produces a shrinking payment). That declining formula extends payoff to 12 to 25 years on most starting balances above $1,500.

Does paying the minimum hurt my credit score?

Paying the minimum on time does not directly hurt your credit score. The score depends on payment history and credit utilization, not payment amount. However, minimum-only payment keeps the balance (and utilization ratio) high for years, which suppresses the score by 30 to 80 FICO points compared to a faster-paid account.

When does the minimum payment make sense?

Two scenarios: (1) you are inside a 0% intro APR window with a clear post-promo plan to clear the balance, so paying the minimum during the promo is fine; (2) you have a true short-term hardship and the minimum is all you can afford for 1 to 3 months. Outside those cases, any payment above the minimum produces meaningfully better math.
