Both methods get you out of debt. The difference is which debt you attack first, and that choice changes how much interest you pay and how soon you see progress.
- Snowball: pay off the smallest balance first.
- Avalanche: pay off the highest interest rate first.
- Either way, you pay the minimum on everything else.
The Quick Verdict
- Avalanche saves more money ($572 here) and finishes a month sooner.
- Snowball gives you your first win 15 months earlier.
- The best method is the one you’ll actually stick with.

The Example: 4 Debts, $900 a Month
Minimum payments add up to $590. The extra $310 a month goes to one target debt at a time.

The badge shows the month each debt hits $0. Notice the snowball clears two debts before the avalanche clears one.
Total debt remaining, month by month
The lines look close, but the avalanche pays $572 less in interest
What this chart shows
- Both lines start at $20,600 and fall at almost the same speed.
- Snowball (blue) gets its first win in month 4.
- Avalanche (green) waits until month 19 for its first win, but its total stays slightly lower most of the way.
- Avalanche finishes one month sooner (27 vs. 28) and saves $572 in interest.
Why the Avalanche Saves Money
- Your extra money hits the 24.99% card first, the debt growing fastest.
- Less balance sits at high rates for long, so less interest piles up.
- The St. Louis Fed notes that paying the highest-rate debt first “leads you to pay off all the debt faster and save money.”
The catch: in this example, your first payoff doesn’t come until month 19. That’s a long time to stay motivated.
Why the Snowball Still Works
- You pay off your first debt in month 4 and your second in month 11.
- Every paid-off debt frees up its minimum payment to roll into the next debt.
- Research backs the motivation effect. A Northwestern Kellogg study of nearly 6,000 debt settlement clients found that people who closed more individual accounts were more likely to finish paying off their debt.
The CFPB’s take: with the snowball, you see quick progress but “may end up paying more in the long run.”
Which One Should You Choose?
Pick the
Snowball if…
- You’ve quit debt plans before
- You need quick wins to stay on track
- Your interest rates are fairly close together
- You have several small balances
Pick the
Avalanche if…
- Saving the most money matters most
- You have one or more high-APR cards
- You’re disciplined without quick wins
- Your biggest balance has the highest rate
Hybrid option: knock out one tiny balance first for a quick win, then switch to the avalanche for everything else.
How to Start Either Method in 5 Steps
Write down the balance, APR, and minimum payment for each card and loan.
Decide the total you can pay each month. Everything above the minimums is your extra payment.
Smallest balance first (snowball) or highest APR first (avalanche).
Send every extra dollar to your target debt. Never skip a minimum.
When a debt hits $0, add its full payment to the next debt on your list.
Frequently Asked Questions
Is the debt avalanche always cheaper?
When everything else is equal, paying the highest rate first costs the least interest. The gap is small when your rates are close and larger when one debt has a much higher APR.
Can I switch methods halfway through?
Yes. Your payment budget stays the same. You just change which debt gets the extra money.
Should I include my mortgage or student loans?
Most people leave the mortgage out and focus on high-interest consumer debt. Federal student loans have their own repayment options, so check those before folding them into a payoff plan.
What if I can only pay the minimums?
Then the order doesn’t matter yet. Look for any extra amount you can add, even $25 a month, and send it to one debt.
