Two popular methods
The avalanche method targets the highest interest rate first. The snowball method targets the smallest balance first. One is usually better mathematically. The other can be better psychologically.
When avalanche helps
If motivation is steady and the highest-rate debt is meaningful, avalanche can reduce total interest and speed up the strongest financial result.
When snowball helps
If the number of accounts feels overwhelming, paying off the smallest balance can create momentum. Fewer payments can make the plan feel lighter.
The best method
The best debt plan is the one that survives normal life. Choose the method you can follow for months, not the one that looks perfect for one weekend.
