Interest is estimated monthly (balance × APR ÷ 12). Your lender may compound daily or add fees, so real figures can differ slightly. A planning estimate, not financial advice.
The Debt Payoff Planner does the same snowball vs avalanche vs minimums comparison in an .xlsx file for Excel, Google Sheets and Apple Numbers, with a month-by-month schedule for up to 8 debts over 20 years, the balance left at the end of each year and a progress bar. $5, instant download, no subscription.

Or the Personal Finance Bundle ($9): debt payoff planner + monthly budget planner + savings goals tracker.
Both methods use the same monthly budget. You pay the minimum on every debt, then put the extra amount on one target debt. When that debt is gone, its minimum rolls over to the next target, so the amount you attack debt with keeps growing.
Debt snowball: target the smallest balance first. You close accounts sooner, which many people find easier to stick with.
Debt avalanche: target the highest APR first. It never costs more interest than the snowball with the same budget, and usually costs less, especially when a large balance also has a high rate.
If the two results are close, pick the one you are more likely to keep doing. If the avalanche saves a lot, it is worth the slower first win.
Why does it say a debt never gets paid off? If a minimum payment is lower than the monthly interest on that debt, paying minimums only will never clear it. Add an extra payment or check the minimum.
