If you're juggling multiple credit cards right now, you've probably heard two pieces of advice that sound completely opposite.
One says pay off your smallest balance first to build momentum.
The other says attack the highest interest rate first to save the most money.
You list every debt by interest rate, highest to lowest, and throw every spare dollar at the top one while making minimum payments on the rest.
Once it's gone, you roll that payment into the next highest rate.
Because credit card APRs are sitting near record highs — many store cards are still north of 29% — knocking out the priciest balance first usually means paying less total interest and finishing sooner.
You ignore rates and target the smallest balance, regardless of what it charges.
Then you roll that payment to the next smallest.
The dollar savings are often smaller, but the psychological payoff comes fast — sometimes in just a few weeks.
For people who've started and quit payoff plans before, that quick win is the whole point.
Say you owe $400 at 18%, $2,000 at 24%, and $6,000 at 28%, with $500 a month to put toward debt.
The avalanche clears the $6,000 card first and typically costs less overall.
The snowball kills the $400 card in month one, then the $2,000 card.
You'll likely pay somewhat more in interest, but you'll see two debts disappear within the first year.
If you're disciplined and motivated by numbers, go avalanche.
If you've bounced between plans and need visible progress to stay in the game, the snowball's early wins may keep you consistent — and consistency is what actually gets people out of debt.
A few practical moves matter no matter which route you take.
Call every card issuer and ask for a lower rate; it works more often than people expect.
Set the minimums on autopay so a late fee never derails you.
And when a balance hits zero, resist the urge to celebrate by spending — redirect that entire payment to the next debt.
One more option worth checking: a 0% balance transfer card.
Moving a high-rate balance to a card with a 15- to 21-month interest-free window can pause the interest clock entirely, as long as you can pay it off before the promo ends.
The typical transfer fee runs 3% to 5%, and any leftover balance after the promo period gets hit with the regular APR.
Whichever method you choose, the plan only works if the money actually goes out the door each month.
A payoff strategy you abandon in February beats nothing.
Our take: the avalanche usually wins on paper, but the snowball wins for real people who need to feel progress before they believe in the process.
Final Thoughts
Pick the one you'll still be following six months from now — that's the version that saves you the most.
