Debt Snowball vs. Debt Avalanche: Which Should You Choose?
What is the Debt Snowball Method?
The debt snowball method has you pay off debts in order from smallest balance to largest, regardless of interest rate. You make minimum payments on everything, then throw all extra money at your smallest debt. Once that's paid off, you roll its payment into the next smallest, building momentum like a snowball rolling downhill.
What is the Debt Avalanche Method?
The debt avalanche method has you pay off debts in order from highest interest rate to lowest, regardless of balance. You make minimum payments on everything, then direct extra money at whichever debt has the highest APR. This minimizes the total interest you pay over the life of your debt.
Comparing the Two Methods
Snowball
Best for staying motivated. Early wins from paying off small debts quickly can keep you committed to the plan, even if it costs slightly more in interest overall.
Avalanche
Best for saving money. Mathematically optimal - you'll pay less total interest and often become debt-free slightly faster, but the first debt paid off may take longer to see results.
Example: Snowball vs. Avalanche in Action
Say you have two debts: a $1,500 personal loan at 10% APR with a $75 minimum payment, and a $4,000 credit card at 26% APR with a $100 minimum payment. You can put an extra $150 per month toward whichever one you prioritize.
- Snowball would target the personal loan first since it has the smaller balance, even though the credit card's rate is much higher. You'd clear the personal loan quickly, but interest keeps accumulating on the high-rate credit card in the meantime.
- Avalanche would target the credit card first since 26% is the higher rate. You'd take longer to see your first debt disappear, but less interest builds up overall because the expensive debt shrinks sooner.
In a case like this - where the smaller balance also happens to have the lower rate - avalanche typically comes out ahead on total interest, though usually by a modest amount over a couple of years rather than a dramatic one. Plug your own numbers into the calculator above to see the real difference for your situation, since the gap depends heavily on your specific balances, rates, and how much extra you can pay.
Important Considerations
Before choosing a strategy, consider:
- How much extra you can realistically commit to paying each month
- Whether you're motivated more by quick wins or by minimizing cost
- Any high-interest debt that's growing faster than you can pay it down
- Whether consolidating some debts first could lower your rates before you start either method
