Debt payoff calculator
The answer
Paying the highest rate first (avalanche), 3 debts totalling $14,400.00 are paid off in 3 yr — around Oct 2029 — with $3,909.86 in interest.
Of the first $520.00, $189.18 is interest and $330.82 comes off what you owe.
On these numbers avalanche costs $919.10 less in interest, and finishes 1 month sooner.

An estimate from the inputs shown, not a promise of a particular date. How we calculate this.
Every debt you owe, in a single plan, with a single date. The answer above is computed from the debts in the calculator and updates as you type. Nothing is saved, and you do not need an account to see it.
Assumptions
- Interest accrues once a month, before that month's payment.
- The APR stays at the rates entered for the whole term.
- No new spending, fees, penalty rate or promotional rate.
- You pay every minimum, plus the extra in full, on time, every month.

What the orders actually change
Both orders pay the same total every month. The only difference is which debt gets the money left over after every minimum is paid. Avalanche sends it to the highest rate, which costs the least interest. Snowball sends it to the smallest balance, which clears a debt sooner and gives you something finished to look at.
Switch the toggle above to see what the choice costs you on your own numbers. On many real sets of debts the difference is smaller than people expect — and on some it is not.
What it does not know
It assumes you keep paying, the rates hold, and you add no new balances. It cannot see a promotional rate ending, a fee, a missed payment penalty rate, or a change in your income. Treat the date as an estimate that is right if the assumptions hold, not a promise.
Several cards at once
Several credit cards are several debts, and this calculator treats them exactly that way: every card keeps its own balance, its own rate and its own minimum, and the money left over after every minimum is paid goes to the card at the front of the order you chose. When that card is cleared, whatever is left that month and its minimum from then on move to the next card in the order. The presets above fill the rows with card-shaped examples; replace them with your own cards to see your own order.
What it cannot see is how your issuer allocates a payment inside a card that carries several rates, or a promotional rate that ends part-way through. Each card is modelled at the single rate you enter.
Questions about this calculator
How many debts can I enter?
As many as you have. Add a row for each with the Add a debt button, and remove the examples you do not need; the page starts with a short list only to stay readable.
Which payoff order should I choose?
Avalanche sends the money left over after every minimum to the highest rate, which costs the least interest. Snowball sends it to the smallest balance, which clears a debt sooner. Switch between them above: the comparison table prints both on your own debts, and says so when they come out the same.
What happens to a minimum payment once a debt is paid off?
It stays in your monthly budget and joins the attack on the next debt in the order. The total you pay each month is held constant for the whole plan, which is why both orders speed up as debts clear.
What if I leave an APR blank?
A blank rate is treated as no interest at all, and the assumptions under the answer name the debt it applies to — so you can see that the estimate is optimistic for that debt if it really does carry a rate.
Where can I see each debt's balance over time?
In the month-by-month schedule under the answer. Each row shows what every debt still owes at the end of that month, the total, and the month each debt is paid off.

Reviewed 2026-09-19. Every figure on this page is produced by the same payoff engine the Dang! Payoff app runs, from the inputs shown, and is an estimate that holds only if the stated assumptions hold. The dates printed here were computed from a plan starting October 2026; the calculator re-anchors to the current month in your browser, so a date you read with JavaScript disabled is the one for that starting month rather than for today.
