If you're carrying balances on multiple cards, the math on how to get rid of them is simpler than the industry makes it sound.
There are two well-known methods: the debt snowball and the debt avalanche.
They just work differently, and picking the wrong one for your personality can mean the difference between finishing and quitting.
List every card you owe money on, along with its balance and its interest rate.
The average credit card rate has been hovering near record highs, above 20% for many accounts, so interest is quietly eating a chunk of every payment you make.
The avalanche method targets the card with the highest interest rate first.
You pay the minimums on everything else, then throw every spare dollar at that one card.
When it's gone, you roll that payment onto the next-highest-rate card.
Because you're killing your most expensive debt first, this approach saves the most money in interest and usually gets you debt-free the fastest.
The snowball method ignores rates and goes after your smallest balance first.
Same drill: minimums everywhere else, all extra cash toward the tiny card.
Pay it off, then roll that payment to the next-smallest.
You'll likely pay more interest overall, but you get a quick win early, and that momentum is real.
Studies on real borrowers have found the snowball often keeps people going longer, because seeing a card hit zero feels like progress.
That psychological edge can matter more than a few hundred dollars in interest.
But if you're disciplined and your rates vary a lot, the avalanche can save you real money.
Pick your smallest balance if you need a morale boost to start, or your highest rate if you're motivated by pure savings.
Either way, the key moves are the same: pay at least the minimum on every account, never miss a due date, and put every extra dollar toward your one target card.
A balance transfer to a 0% intro APR card can pause interest for a stretch, though you'll usually pay a 3% to 5% fee and need a plan to clear the balance before the regular rate kicks in.
And a quick call to your card issuers to ask for a lower APR sometimes works, especially if you've been paying on time.
Store cards and buy-now-pay-later plans often carry their own interest and fees, so they belong in your list too.
And a debt consolidation loan only helps if you don't run the cards back up afterward, which is the most common way people end up worse off.
Whichever route you choose, the plan only works if the payments keep going out every month, even the boring ones.
My take: the "best" method is the one you'll actually stick with for the 12 to 24 months it usually takes.
If you've abandoned payoff plans before, start with the smallest balance, bank the win, and let the momentum carry you.
Final Thoughts
If you're steady and your rates are all over the place, let the avalanche save you the cash.
