Two Approaches to Debt Payoff
If you have multiple debts, there are two primary strategies for paying them off: the Debt Avalanche (mathematically optimal) and the Debt Snowball (psychologically effective). Understanding both helps you choose the approach most likely to work for your personality and situation.
The Debt Avalanche Method
The avalanche method prioritizes paying off debts in order of interest rate, from highest to lowest. You make minimum payments on all debts, then put every extra dollar toward the highest-rate debt. Once it is paid off, you roll that payment to the next highest-rate debt.
Advantage: Minimizes total interest paid. You will pay less money overall and get out of debt faster in terms of total dollars spent.
Disadvantage: If your highest-rate debt has a large balance, it can take a long time to see progress, which can be demotivating.
The Debt Snowball Method
The snowball method, popularized by Dave Ramsey, prioritizes paying off debts in order of balance, from smallest to largest. You make minimum payments on all debts, then put every extra dollar toward the smallest balance. Once it is paid off, you roll that payment to the next smallest balance.
Advantage: Quick wins. Paying off small debts fast creates momentum and motivation to continue.
Disadvantage: You may pay more in total interest, especially if your smallest debts have lower rates than your larger ones.
Which Method Is Better?
Research in behavioral finance shows that the snowball method leads to higher debt payoff rates in practice, even though the avalanche method is mathematically superior. The psychological boost of eliminating debts keeps people motivated. However, if the interest rate difference between your debts is large (e.g., 5% vs. 25%), the avalanche method's savings can be substantial enough to overcome the motivation gap.
A Hybrid Approach
Many financial advisors recommend a hybrid: use the snowball to eliminate one or two small debts quickly for motivation, then switch to the avalanche for the remaining larger debts. Use our Loan Calculator to model the total cost of different payoff strategies.
