Debt snowball calculator
The answer
3 debts totalling $17,500.00 are paid off in 3 yr 1 mo — around Oct 2029 — with $4,533.26 in interest.
Of the first $605.00, $208.55 is interest and $396.45 comes off what you owe.
On these numbers avalanche costs $459.12 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.
The snowball method pays every minimum, then puts everything left over onto the debt with the smallest balance — so a debt disappears sooner and its freed-up minimum joins the attack on whatever follows.
Switch to avalanche to see the same debts attacked by rate, and what the difference costs.

The order is recomputed every month, so a debt that becomes the smallest mid-plan takes over the attack.

What snowball is actually for
Snowball is not the cheapest order and does not claim to be. It is the order that produces a finished debt soonest, which for a lot of people is the difference between a plan they keep and a plan they abandon early.
If you would rather minimise interest, avalanche is the other order — and comparing them on your own numbers is the honest way to choose.

Reviewed 2026-09-17. 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 September 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.
