Debt snowball vs avalanche
Two orders, one mechanism. Both methods pay every minimum and direct all extra money at one target debt; both roll a cleared debt's minimum into the next target. Snowball targets the smallest balance — the earliest finished account. Avalanche targets the highest APR — the least total interest. The CFPB describes both in its debt-reduction guidance; neither is “correct.” They are prices for different things, and the honest move is to show you both prices.
The same debts, both ways
Three example debts, deliberately chosen so the two methods disagree — a store card at $6,000 and 26.99% ($150 min), a credit union loan at $900 and 14.99% ($35 min), and a Visa at $3,000 and 21.99% ($75 min), with $150 extra a month. Snowball starts with the small loan; avalanche starts with the store card. Computed by the same engine as the planner, not typed in by hand:
| ❄️ Snowball | 🏔️ Avalanche | |
|---|---|---|
| First debt cleared | February 1, 2027 | November 1, 2028 |
| Debt-free date | July 1, 2029 | June 1, 2029 |
| Total interest | $4,205.06 | $3,742.63 |
In this example, avalanche costs $462.43 less interest and finishes 1 month sooner, while snowball clears its first account no later than avalanche does. Your debts will produce different numbers, which is why the planner exists.
