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.
