Practical guide
Using the Debt Snowball Strategy Calculator well
Who this is for
Borrowers who stay motivated by clearing small balances first.
Worked example
Three cards with balances $400, $2,200, and $6,000—snowball attacks the $400 first while paying minimums elsewhere, then rolls the freed payment upward.
Behavior is part of the math
If avalanche looks better on interest but you abandon plans, snowball’s early wins can be the rational choice. Compare both with the same surplus.
Common pitfalls
- Ignoring a crushing high-APR balance when the interest gap is huge
- Stopping the plan after the first win
