Debt Snowball vs. Avalanche: Which Is Better? (With a Worked Example)

If you have more than one debt, the hardest question isn't whether to pay extra. It's where the extra dollar goes first. The two most popular answers are the debt snowball and the debt avalanche. Both work. They just reward different things.

The two methods in one sentence each

• Debt snowball: pay the minimum on everything, then put every extra dollar on the smallest balance. When it's paid off, roll that payment into the next-smallest.
• Debt avalanche: pay the minimum on everything, then put every extra dollar on the highest interest rate (APR). When it's paid off, roll that payment into the next-highest rate.

The mechanics are identical: same total monthly budget, minimums on everything, and paid-off payments roll forward. Only the order changes.

A worked example: same debts, same budget

Here are three made-up debts:

The minimums add up to $275 a month. Say you can find $200 extra, for a total of $475 a month. We ran both orders month by month. Interest accrues monthly at APR divided by 12, minimums are paid first, and the extra goes to the focus debt.

Avalanche saves about $350 and finishes a month sooner. Snowball gives you your first win six months earlier.

For comparison, if you paid the same $275 with no extra (but still rolled each finished payment forward), the same debts would take about 59 months and roughly $6,340 in interest. Finding even a modest extra payment matters more than which method you pick.

Illustrative estimate. Your lenders' interest calculation, fees, and minimum-payment rules will differ.

So which is better?

• Choose avalanche if the APRs are far apart, you're motivated by the math, and the highest-rate debt isn't so large that you'll lose steam before you see progress.
• Choose snowball if you've tried before and stalled, the APRs are similar, or one small balance is the thing nagging at you every month.
• When it's a near tie (like the one-month difference above), pick the one you'll stick with. Consistency beats optimization.

A common hybrid is to snowball one tiny balance for a quick win, then switch to avalanche.

How to make your own debt payoff plan

1. Gather your numbers. Each statement shows the balance, APR, and minimum payment.
2. Find your extra amount. Even $25–$50 changes the timeline. Look at subscriptions, dining, or a side income.
3. Choose an order (snowball or avalanche).
4. Automate the minimums, and make the extra payment by hand so you see it happen.
5. Recalculate when something changes: a raise, a 0% balance-transfer offer, a new debt.

Do this on your phone, without linking your bank

Spreadsheets are powerful, and a lot of people abandon them by week three. We built Payoff Path so the plan is one tap away:

• Enter balances, APRs, and minimums. Payoff Path turns them into a payoff estimate.
• Pick avalanche or snowball, adjust your extra monthly payment, and watch the estimated time and interest change.
• Log payments and see which debt to tackle next.
• No bank login. Your numbers stay on your device. Payoff Path calculates a plan; it never moves money.

Track up to three debts free. Payoff Path Pro ($4.99 one-time, U.S.) unlocks unlimited debts, the full month-by-month schedule, the side-by-side avalanche-versus-snowball comparison, and CSV export. Choosing one path is available before that upgrade. The comparison of both, side by side, is part of Pro.
