Credit Cards Payoff Calculator
Several cards, one goal: a debt-free date. This credit cards payoff calculator models every balance, APR and minimum together, layers on your extra monthly payment, and returns one combined payoff date, the total interest, and a snowball-vs-avalanche comparison.

How your multi-card payoff timeline is calculated
Each month the calculator runs the same loop lenders’ balances follow, across all your cards at once:
interest = balance × APR / 1200 (per card, each month)
pool = extra + minimums freed by cleared cards
target = highest APR (avalanche) or smallest balance (snowball)
First, interest accrues on every open card. Then each card is paid its minimum (capped at its balance). The leftover — your extra plus any minimums freed up by cards that are already paid off — forms an attack pool that’s applied entirely to one target card: the highest-APR card under avalanche, or the smallest-balance card under snowball. When a card clears mid-month, the remaining pool cascades to the next target. The combined payoff month is when the last card hits zero, and total interest is summed across every card. Assumptions: no new purchases are added, APRs and minimums stay fixed, and the first payment lands one month from today. If a card’s minimum can’t cover its own monthly interest and the attack pool never reaches it, its balance never falls — the calculator flags that rather than pretending it clears.
Three cards, $12,300, three plans
A Visa, a store card and a rewards card — $300 of minimums between them. What changes everything is the $200 on top.
Minimums alone: $300 a month
to debt-free82 months
- Covering only the $300 of minimums keeps all three cards fed for six years and ten months.
- Interest across the three cards reaches $12,189 — nearly the $12,300 that was borrowed.
- The store card, with the highest rate and smallest minimum, hangs on until the very end.
Nothing is missed, nothing is late, and the balances still take almost seven years to clear.

to debt-free34 months
- Adding $200 a month cuts the timeline from 82 months to 34 — four years sooner.
- Interest falls to $4,200, a saving of $7,989 over minimums alone.
- The 26.99% store card goes first, then the Visa, then the rewards card.
The extra $200 does the heavy work; targeting the priciest card first keeps interest lowest.
Load this example (opens in a new tab)The same $200, smallest balance first
to debt-free34 months
- The $2,500 store card clears in 11 months — the first win comes fast.
- Total interest is $4,319: $119 more than avalanche, on the same 34-month clock.
- The Visa, the biggest balance, waits until the end instead of the middle.
For $119, snowball buys an early win — if that keeps the plan alive, it is money well spent.

Clearing several cards, in plain English
- Pay every minimum, always. Missing one triggers late fees and penalty APRs that dwarf any strategy difference — cover all minimums first, then attack one card.
- Avalanche is the cheapest. Targeting the highest APR first, this snowball credit card payoff calculator’s avalanche mode pays the least total interest and usually finishes soonest.
- Snowball builds momentum. Clearing the smallest balance first gives a quick win; if that keeps you paying, the small extra interest can be worth it.
- The rollover is the engine. When a card is paid off, its old minimum joins your extra payment and pours into the next card — payoff speeds up as you go.
- Extra beats order. Raising your monthly payment moves the payoff date far more than switching methods — as a credit card payoff calculator with extra payments shows, an added $100–$200 is transformative.

Frequently asked questions
How should I pay off multiple credit cards at once?
Always cover the minimum payment on every card so none go delinquent, then throw every spare dollar at one target card until it clears. The avalanche method targets the highest-APR card first, which mathematically minimizes interest; the snowball method targets the smallest balance first for quicker psychological wins. When a card is paid off, its freed-up minimum rolls into the next target — that “rollover” is what accelerates payoff. This multiple credit card payoff calculator runs both methods on your real cards so you can pick with your eyes open.
What is the difference between the avalanche and snowball methods for cards?
Avalanche orders your cards by interest rate and attacks the highest APR first, so you pay the least total interest and are usually debt-free the fastest. Snowball orders by balance and clears the smallest card first, giving you a motivating win sooner even though it can cost a bit more interest. The gap is often small — a few hundred dollars on typical balances — so if snowball keeps you on track, the momentum can be worth more than the math. Toggle the two above to see your exact interest-and-time difference.
How much faster will extra payments clear my cards?
Dramatically faster, because credit-card APRs are high and every extra dollar goes straight to principal. On three cards totaling about $12,300 at 20–27% APR, paying only the minimums can take a decade, while adding $200 a month can clear them in roughly three years and save thousands in interest. Enter your own extra amount above — this credit card payoff calculator with extra payments updates the combined payoff date and interest instantly.
Which credit card should I pay off first?
If you want to spend the least, pay the card with the highest APR first (avalanche) — interest is charged on the rate, not the balance, so the priciest debt costs you most every month it stays open. If you want momentum, pay the smallest balance first (snowball). Either way, keep paying every other card’s minimum so nothing slips into default. The per-card timeline above shows the exact order and payoff month for the method you choose.
How much total interest will I pay across all my cards?
It depends on your balances, APRs, and how much you pay above the minimums. The hero number above sums the interest across every card for your chosen method, and the avalanche-vs-snowball comparison shows how much interest each approach costs. Because the calculator assumes no new purchases and fixed rates, treat the figure as a clean “if I stop charging and stick to the plan” estimate.
Does the order I pay my cards in actually matter?
Yes, but usually less than the amount you pay. Ordering by APR (avalanche) versus by balance (snowball) typically changes total interest by a modest amount, while raising your monthly payment changes it a lot. The biggest lever is the extra you can commit each month; the order mainly decides whether you optimize for lowest cost or fastest first win. Run both above and compare the interest and months for your specific cards.
