Debt Snowball vs Avalanche: Which Payoff Method Is Better?
Both methods start the same way: pay the minimum on every debt, then send all your extra money to one target debt. When that debt is paid off, you roll its payment into the next target. The only difference is the order in which you attack your debts.
The avalanche method
With the avalanche method you target the debt with the highest interest rate first. Because high-rate debt grows fastest, paying it down first usually minimizes the total interest you pay and can shorten your timeline. The drawback is that your highest-rate debt may also be a large balance, so it can be a long time before you feel any progress.
The snowball method
With the snowball method you target the smallest balance first, regardless of rate. You may pay somewhat more interest overall, but you eliminate whole debts sooner, which shortens your list of bills and frees up their minimum payments. Some behavioral research suggests that early wins help people stay committed to a plan, which matters because a plan only works if you finish it.
An example
Suppose you have a $1,200 credit card at 19%, a $4,500 credit card at 27%, and a $9,000 car loan at 6%. The snowball order is the $1,200 card, then the $4,500 card, then the car loan. The avalanche order is the $4,500 card (27%), then the $1,200 card (19%), then the car loan. Both finish with the car loan, but avalanche attacks the most expensive debt first.
How to choose
If you are motivated by numbers and want the lowest cost, choose avalanche. If you have struggled to stay on track before, or you have several small debts, snowball can be easier to maintain. A hybrid also works: clear one or two tiny debts for quick wins, then switch to avalanche.
What matters more than the method
The amount you pay each month matters more than the order. Even a modest extra payment, kept consistent and rolled forward as debts disappear, changes your payoff date far more than the choice between the two methods. Also avoid adding new balances while you pay down old ones.
Our debt payoff calculator runs both methods on your own balances, rates and extra payment so you can compare the debt-free date and total interest side by side.
