Three bills sit on the kitchen counter: a furniture loan, a personal loan and a credit card statement with a balance that never seems to move. You’ve found an extra $200 a month to put toward them. Now you have to decide where that $200 goes first.
There are two popular answers. The snowball method says pay off the smallest balance first. The avalanche method says go after the highest interest rate first.
Both work. The snowball gets you an early win. The avalanche costs less. The right pick is the one you’ll keep paying.
This is general information, not personal financial advice.
Both Methods Start the Same Way
Every month, you pay the minimum on every debt. That part never changes. Missing a minimum can bring late fees and hurt your credit, so it always comes first.
Then you take whatever extra money you have and point all of it at one target debt. When that debt hits zero, its old minimum payment joins the extra money, and the whole amount rolls to the next target. Your payment gets bigger each time a debt disappears.
The only difference between the two methods is how you choose the target.
If the Minimums Alone Are Too Much
Both methods assume you can cover every minimum each month. If you can’t, the order matters less than getting help early. A nonprofit credit counselor can go over your budget with you and may suggest a debt management plan (one monthly payment through the agency, often with lower interest rates the agency arranges with your card companies). The Consumer Financial Protection Bureau (CFPB, the federal agency that oversees consumer loans and credit cards) explains what credit counseling is and how to pick a reputable agency.
The Snowball: Smallest Balance First
With the snowball, you list your debts from smallest balance to largest and ignore the interest rates. The smallest one gets all the extra cash.
The point is speed. You close an account early, sometimes within a few months, and that win can keep you motivated. The CFPB says this approach shows progress quickly but can cost more over time, because your most expensive debt keeps charging interest longer.
There’s some research behind the motivation idea. A study from Northwestern University’s Kellogg School of Management looked at nearly 6,000 people in a debt settlement program (a service that negotiates down what you owe). How many accounts they closed predicted whether they finished the program better than how many dollars they’d paid.
The researchers were careful with that finding. They noted the two measures are hard to separate, and they said starting small makes the most sense when the interest rates on your debts aren’t far apart.
The Avalanche: Highest Interest Rate First
With the avalanche, you list your debts from highest interest rate to lowest. On a statement, look for the APR (annual percentage rate), which is the number to use here. The debt charging the most interest gets the extra cash, no matter its size.
This is the cheapest route on paper. Every extra dollar goes where interest piles up fastest, so you pay less overall and often finish a bit sooner. An explainer from the Federal Reserve Bank of St. Louis walks through a two-card example and lands in the same place: paying the higher-rate card first costs the least in interest.
The catch is patience. If your highest-rate debt is also your biggest, it can take a year or more to close a single account.
A Side-by-Side Example
Here’s a made-up but realistic set of debts:
Furniture financing: $800 at 10% interest, $25 minimum
Personal loan: $3,000 at 15% interest, $90 minimum
Credit card: $4,000 at 24% interest, $100 minimum
That’s $215 a month in minimums. Add the $200 extra, and the monthly debt budget is $415. A 24% card isn’t unusual: the Federal Reserve reported that credit card accounts being charged interest averaged a little over 22% in August 2026.
We ran both methods month by month, assuming fixed minimums and no new charges. Here are the results:
Snowball
Avalanche
First debt paid off
Month 4 (furniture)
Month 16 (credit card)
Debt-free
Month 24
Month 23
Total interest paid
$1,768
$1,404
How it feels
Early win, higher cost
Long wait, then a fast finish
In this case the avalanche saves $364 and one month. The snowball gets you a zero balance a full year earlier. So the real trade is a few hundred dollars for a much faster first win.
Your gap could be bigger or smaller. It grows when your smallest debt has a low rate and your biggest has a high one. It shrinks when your rates are close together.
Which One Fits You
The snowball may suit you if:
You’ve started a payoff plan before and quit partway through.
You have a few small balances you could clear in a couple of months.
Money is tight, and freeing up one minimum payment fast would give you breathing room.
The avalanche may suit you if:
One debt has a much higher rate than the rest.
Watching your total interest drop motivates you more than counting closed accounts.
You’re comfortable waiting a while for your first payoff.
As the St. Louis Fed puts it, the best plan is the one you finish. A cheaper plan you drop in March costs more than a slower one you stick with.
You Can Mix the Two
You can also combine them. A few moves people use:
Start small, then switch: Clear one tiny balance for a quick win, then move to the highest rate.
Watch promo deadlines: If a 0% promotional rate (common on balance transfers and store financing) is about to end and the rate will jump, that debt may deserve to move up the list.
Recheck your rates: Many card rates are variable, which means they can rise or fall over time. Update your list every few months.
Habits That Help Either Plan
Stop adding new balances: The math falls apart if the card keeps getting used. Cash or debit for daily spending can help for a while.
Automate the minimums: Autopay on every minimum means a hectic week can’t cost you a late fee.
Aim the extra payment: On loans, ask your lender how extra payments are applied. If there’s a choice, ask for them to go toward principal (the amount you borrowed).
Find the extra money: Small, steady amounts from a side gig, paid surveys or a canceled subscription add up when they all go to one target. Earnings vary, so plan around what you actually bring in.
Your First Move Tonight
Grab your latest statements and write down three things for each debt: the balance, the interest rate and the minimum payment. Sort that list two ways, smallest balance first and highest rate first.
If the same debt lands on top both times, your choice is made. If not, go with the order you’re more likely to stick with, and send your first extra payment this week.
