Understanding the result
Example: For $1,000 at 5% ($50 min) and $8,000 at 20% ($200 min) with $100 extra, both plans take 34 months but avalanche pays $2,634.58 interest versus $2,768.13 — saving $133.55.
Frequently asked questions
If both strategies take the same time to pay off, why does avalanche save money? Avalanche directs extra payments to the highest-interest debt first, so less total interest accrues along the way even when the overall payoff timeline matches snowball's.
Why would anyone choose snowball if avalanche saves more money? Snowball pays off the smallest balance first, delivering an early psychological win that can help people stay motivated, even though it usually costs a bit more in total interest.
