Answer

Debt snowball vs avalanche: which is better?

Avalanche (highest interest rate first) always costs the same or less: on our four-debt example it saves $349 in interest. Snowball (smallest balance first) pays off the first debt sooner, which keeps many people motivated.

The example

Snowball vs avalanche: four debts, $200 extra a month
SnowballAvalanche
Total interest$4,176$3,827
Debt-free in2 years, 9 months2 years, 8 months
First debt gonemonth 5 (Medical bill)month 11 (Store card)
OrderMedical bill → Store card → Visa → Car loanStore card → Visa → Car loan → Medical bill

Debts: medical bill $1,200 at 0%, store card $2,500 at 27%, Visa $7,000 at 22% and car loan $9,500 at 7%, paying the minimums plus $200 ($760 a month).

When snowball makes sense

If you have several small balances, or you’ve tried and stalled before, early wins can matter more than a few hundred dollars of interest. If the highest-rate debt is also the smallest, both methods are the same.

More questions

Can I mix the two?

Yes: clear one tiny balance for a quick win, then switch to highest-rate-first.

Does the extra amount matter more than the method?

Usually yes: adding even $50–$100 a month shortens payoff more than switching method.
