SnowballAvalanche

The difference in one sentence

The snowball orders debts by balance (smallest first) to win sooner; the avalanche orders them by interest rate (highest first) to pay less. Everything else, including the minimums on every debt and the rollover of freed payments, is identical.

Questions people ask

Is the debt snowball or avalanche better?

The avalanche is cheaper, always or tied. The snowball gets your first debt paid off sooner in most cases. The best method is the one you keep doing every month, so compare your real numbers above and look at how big the dollar gap actually is.

How much more does the snowball cost?

Often less than people expect. With the example debts on this page, the difference is under $200 over more than two years. It grows when a large balance has a much higher rate than your small ones.

What does the research say?

Studies by researchers at Kellogg School of Management and published in Harvard Business Review found people who focused on paying off whole accounts, or concentrated payments on one account, made more progress and felt more motivated. These are behavioural findings; mathematically, highest-rate-first is still cheapest.

Can I combine the two?

Yes. A common hybrid is to clear one or two tiny debts first for momentum, then switch to highest-rate order for the rest. Another is to snowball but make an exception for a card whose promo rate is about to expire.
