Snowball vs avalanche explained

Both strategies use the same total monthly payment. The difference is where the extra money goes. Snowball directs it to the smallest balance — you get the satisfaction of closing accounts quickly. Avalanche directs it to the highest interest rate — you pay less overall.

For most people with credit card debt at 20%+, the avalanche method saves a meaningful amount. But if you've struggled to stay motivated before, the snowball's quick wins can be worth the extra interest cost.

Example: 3 debts, $600/month total payment

Min payments: ~$480/mo

The avalanche method pays off debts from highest interest rate to lowest. It minimizes the total interest you pay over time and is the mathematically optimal strategy for saving money.

The avalanche method always saves more in total interest paid. The snowball method may be better if you need motivational wins to stay on track, since eliminating accounts quickly provides momentum.
