Debt snowball method

The snowball method pays minimums on every debt, then directs all extra money to the smallest balance. When a debt is cleared, its minimum rolls into the extra pool for the next target.

Psychologically, quick wins can build momentum. Mathematically, the avalanche method (highest APR first) often saves more interest — compare both.

Example: three debts ($800 @ 12%, $2,500 @ 18%, $6,000 @ 9%) with $200 extra/month — snowball clears the $800 balance first.
