Credit Card Payoff Calculator — Minimum Payment vs a Real Plan
The minimum payment is designed to shrink as your balance does. That one design choice costs years. Here are both timelines, side by side.
Minimum modeled as interest + 1% of balance, $35 floor — the industry-standard formula.

How it works
A credit card minimum payment is usually computed as that month's interest plus 1% of the balance, with a floor around $35. Read that formula again: only 1% of what you owe actually leaves the debt each month, and as the balance shrinks, the payment shrinks with it — so the last thousand dollars gets paid down almost as slowly as the first. The payment is engineered never to feel heavy, which is exactly why it never finishes.
The defaults show the trap at real scale. On a $6,500 balance at 24.99% APR, the first minimum payment is about $200. Keep paying minimums and the card takes 19 yr 1 mo to reach zero — August 2045 — with $11,948 in interest, almost twice the original balance. Now hold that same first payment steady instead: a fixed $200 every month clears the card in 4 yr 7 mo, by February 2031, with $4,461 in interest. Same starting payment. The only difference is that the plan doesn't shrink — $7,487 less interest, done 14 yr 6 mo sooner.
The chart draws both balances month by month: the red curve is the minimum-payment glide, the green one is the fixed plan diving to zero. If you're juggling several cards, the debt payoff calculator runs the same engine on a whole debt list. ClariFi tracks the real thing — every card payment logged automatically, so the plan you pick here is the plan you can actually watch happen.
The formula
interest (monthly) = balance × APR ÷ 12 minimum payment = max(interest + 1% × balance, $35) ← recomputed as the balance falls fixed plan = the same dollar amount, every month Example: $6,500 at 24.99% APR — first minimum ≈ $200 minimums → 19 yr 1 mo, $11,948 interest, done Aug 2045 fixed $200 → 4 yr 7 mo, $4,461 interest, done Feb 2031 difference → $7,487 less interest — 14 yr 6 mo sooner
Honest assumptions
- Issuer minimum formulas vary — interest + 1% of balance with a $35 floor is the common pattern this page models, but some issuers use a flat 2% of balance or a different floor. Check your statement's fine print for yours.
- No new purchases, annual fees, or late fees are modeled — the card is frozen at today's balance. Every new swipe restarts the math.
- The APR is held constant. Real card rates are variable, and a missed payment can trigger a higher penalty rate.
- The 24.99% default is an example of a typical current card APR, not your card's — type in your real rate from your statement.
- This page is arithmetic, not underwriting.
Questions people ask
Why do minimum payments take decades?
Because the payment is a percentage of the balance, it shrinks every month right alongside the debt — so progress decelerates forever. Early on, most of each minimum is interest; near the end, the $35 floor is the only thing dragging the balance to zero at all. A fixed payment breaks the loop: the dollar amount stays constant while the interest portion falls, so an ever-growing share hits principal each month.
What formula does my issuer actually use?
The most common is the one modeled here — that month's interest plus 1% of the balance, with a floor around $25–$40. Some issuers use a flat percentage of the balance (often 2%) that already includes interest, and a few add past-due fees on top. Your cardholder agreement and the minimum-payment warning box on every statement spell out yours, along with an issuer-computed version of this page's math.
Avalanche or snowball across several cards?
Avalanche pays extra toward the highest-APR card first and always wins on total interest; snowball pays the smallest balance first and wins on momentum, because closed accounts feel like progress. The math gap between them is usually smaller than the cost of quitting halfway. Either way, the mechanic is this page's mechanic: pay minimums on everything, and aim one fixed extra amount at a single target. The debt payoff calculator runs the full-list version.
Is a balance transfer worth it?
The math can work: moving a balance to a card with a 0% promotional period pauses interest, typically for 12–21 months, in exchange for a transfer fee of about 3–5% upfront. On the default $6,500, that's roughly $195–$325 against interest that would otherwise run about $135 in the first month alone. The catch is the deadline — any balance left when the promotional rate ends starts compounding at the card's regular APR. That's a description of the arithmetic, not a recommendation; the fixed-payment plan above works on any card, transferred or not.
