Paying off credit cards feels like trying to empty a bathtub while the faucet is still running.
With the average card rate hovering near 20%, minimum payments barely chip at the principal.
Two popular methods promise a way out, and they disagree on one crucial point: which balance you attack first.
The avalanche method targets the highest interest rate first.
You pay minimums on everything else, then throw every spare dollar at the priciest card.
Once it's gone, you roll that payment into the next highest rate.
Mathematically, this saves the most money and clears debt fastest.
The snowball method, popularized by Dave Ramsey, ignores rates and targets the smallest balance first.
You still pay minimums elsewhere, but you knock out the little card fast, then move to the next smallest.
Researchers at Harvard Business School and Boston College tracked real borrowers and found the snowball method often wins in practice, even though it costs more on paper.
The reason: people who close an account early feel progress and keep going.
Quitting is the real enemy, not interest.
The gap between the two isn't always huge.
If your balances are similar in size, or your rates are close, the difference in total interest may be a few hundred dollars.
But if you're carrying a $9,000 card at 24% and a $600 store card at 26%, the snowball gets you a win in weeks while the avalanche grinds for months.
Run the numbers on your own debt before choosing.
List every balance, its rate, and its minimum payment.
Then decide what you'll actually stick with.
A slightly slower plan you finish beats a perfect plan you abandon in month three.
One hybrid move works for many households: knock out one tiny balance for the psychological boost, then switch to avalanche order for the rest.
You get the early win and the long-term savings.
Either way, two habits matter more than the method.
First, stop adding new charges to the cards you're paying down.
Second, automate the payments so you can't talk yourself out of them.
A windfall like a tax refund or bonus can erase months of progress if you send it straight to the target balance.
Our take: the avalanche is the better tool on paper, but the snowball is the better tool for human beings.
Final Thoughts
Pick the one you'll still be doing in six months, not the one that looks smart in a spreadsheet.
