Debt snowball vs avalanche: which method wins?

Two popular payoff strategies show up in almost every personal-finance conversation. They use the same monthly budget. They differ in which debt you attack first.

Debt snowball

List debts from the smallest balance to the largest, regardless of interest rate. Pay minimums on everything, and throw every extra dollar at the smallest balance. When it is gone, roll that payment into the next-smallest debt.

• Pros: early wins, simpler motivation for many people.
• Cons: you may pay more interest than avalanche if high-APR debts sit untouched.

Debt avalanche

List debts from the highest interest rate to the lowest. Minimums on everything; extra money goes to the highest APR first.

• Pros: usually the lowest total interest if you stick with it.
• Cons: the first “win” can take longer if the high-APR balance is large.

Which should you pick?

If you will quit without quick progress, snowball’s psychology can matter more than a few dollars of interest. If you are steady and the APR gap is wide (for example 22% cards vs 6% student loans), avalanche usually costs less. The only honest way to decide for your debts is to run both with the same extra payment and compare the debt-free date and interest.

For multiple debts, you need a timeline that rolls freed-up minimums into the next target. That is what a snowball/avalanche spreadsheet is for.
