Two debt payoff methods dominate every personal finance thread, and they disagree on one crucial point: whether to chase the smallest balance or the highest interest rate first.
The avalanche method targets your highest-rate debt first, since that's where interest quietly eats the most money.
The snowball method ignores rates and knocks out your smallest balance first, so you get a quick win fast.
Say you owe $1,200 on a store card at 26% APR, $4,000 on a credit card at 19%, and $9,000 on a personal loan at 11%.
Put every spare dollar toward the 26% card first, and you'll pay less total interest than any other order.
The savings aren't trivial either — on balances like these, the avalanche can shave hundreds off what you hand over.
But there's a catch the spreadsheets don't capture.
The avalanche often means staring down a big balance for months before anything disappears.
The snowball gives you a finished account in weeks, and that psychological hit of "one down" is why a lot of people stick with it long enough to actually finish.
Studies of real borrowers found that people who paid off smaller balances first were more likely to stay with their plan and clear their debts overall.
Feeling like you're winning matters more than saving a few extra dollars if the alternative is quitting in month three.
There's also a middle path worth knowing.
You can split the difference by making minimum payments on everything, then throwing extra cash at whichever account is both small and high-rate.
That way you get a fast win without ignoring expensive interest.
A few things to check before you pick a lane.
Confirm whether your card issuer charges a prepayment penalty — most don't, but personal loans sometimes do.
Also check whether your extra payments are being applied to principal rather than next month's bill, which some servicers do by default.
Timing your move around a balance transfer offer can also tip the scales.
A 0% intro APR period on a new card can pause interest entirely while you attack the rest, though you'll want to clear the balance before the regular rate kicks in.
Watch the transfer fee too, usually 3% to 5% of what you move.
Whichever route you choose, the biggest factor isn't the strategy — it's whether you keep going.
Automate the extra payment so it leaves your checking account the day you get paid, and you remove the monthly temptation to skip it.
My take: run the avalanche if you're wired for spreadsheets and can tolerate a slow start.
Pick the snowball if you've abandoned payoff plans before, because finishing beats optimizing.

The best method is the one you'll still be doing six months from now.
