When eliminating high-interest consumer debt, two methodologies dominate personal finance: The Debt Avalanche and The Debt Snowball.
Method Breakdown
1. The Debt Avalanche (Mathematical Winner)
- Strategy: List debts in order from highest interest rate to lowest, regardless of balance.
- Payoff Focus: Pay minimums on all debts, throw every extra dollar at the highest interest rate (e.g. 27% APR Credit Card).
- Outcome: Minimizes total interest paid and gets you debt-free in the shortest time mathematically possible.
2. The Debt Snowball (Psychological Winner)
- Strategy: List debts from smallest balance to largest balance, regardless of interest rate.
- Payoff Focus: Eliminate smallest balance first to build quick behavioral momentum.
- Outcome: Faster emotional wins that keep struggling borrowers committed to the plan.
Real Example on $45,000 Total Debt
On typical blended credit cards and auto loans, the Debt Avalanche saves $3,800 to $7,200 in pure interest compared to the Snowball approach.
