Psychology vs. Math

The debate between Snowball and Avalanche is the oldest argument in personal finance. The math says Avalanche wins every time. But the human brain runs on dopamine, not spreadsheets.

The Two Contenders

  • ❄️ Snowball (Behavioral): Target the smallest balance. Ignore rates. When it's gone, roll its payment into the next one.
    Why it works: Quick wins build momentum. You feel "success" sooner.
  • 🏔️ Avalanche (Mathematical): Target the highest rate. Ignore balances.
    Why it works: Reduces the Weighted Average Rate, saving total interest.
Case Study: The "Stuck" Borrower

Mark had $100k in debt. He tried the Avalanche method for 2 years but felt like he was making no progress on his giant $40k loan. He quit.

The Pivot: He switched to the Snowball, paid off a small $2k loan in 3 months, and felt a rush of victory. That energy carried him to pay off the next $5k loan. He finished debt-free 1 year *faster* than the Avalanche projection simply because he actually stuck to the plan.

Strategy FAQ

Why does Dave Ramsey love the Snowball?

Because personal finance is 80% behavior. Eliminating a specific debt completely reduces the number of bills you receive, reducing mental clutter and anxiety.

Is there a 'Hybrid' method?

Yes. Knock out any tiny annoying debts (under $1,000) using the Snowball to clean up your dashboard, then switch to the Avalanche for the heavy lifting on high-interest loans.
