Debt Snowball vs Debt Avalanche: Which One Should You Use?

When I first looked at my debts I had no idea where to start. Do I pay off the smallest one first? The one with the highest interest? Just throw extra money at all of them?

That confusion is exactly why two simple strategies were created: the debt snowball and the debt avalanche. Both work. Both will get you out of debt. But they work differently, and one might be a better fit for how you think and feel about money.

Let me break both down in plain English.

The Debt Snowball: Start Small, Build Momentum

The snowball method is simple — you pay off your smallest debt first, no matter what the interest rate is.

Here's how it works:

1. List all your debts from smallest balance to largest

2. Pay the minimum on everything

3. Put any extra money toward the smallest debt

4. When that one is gone, take what you were paying and add it to the next smallest

5. Keep going until they're all paid off

The idea behind it is psychological. When you pay off a debt completely even a small one it feels great. That feeling keeps you going. Like a snowball rolling down a hill, your payments get bigger and bigger as each debt disappears.

Quick Example

Let's say you have these three debts:

With snowball and $200 extra per month you'd pay them off in this order:

• Store Card gone — Month 3

• Visa gone — Month 11

• Car Loan gone — Month 28

Total interest paid: around $3,100

The Debt Avalanche: Pay Less Interest Overall

The avalanche method is all about math. Instead of starting with the smallest balance, you start with the highest interest rate.

Here's how it works:

1. List all your debts from highest interest rate to lowest

2. Pay the minimum on everything

3. Put any extra money toward the highest interest debt

4. When that one is paid off, move to the next highest rate

5. Keep going until they're all gone

The logic here is simple — high interest debts cost you the most money every single month. The faster you kill them, the less you pay overall.

Same Example, Different Order

Using the same three debts with $200 extra per month:

• Visa gone — Month 11 (highest rate at 24.99%)

• Store Card gone — Month 14 (second highest at 22%)

• Car Loan gone — Month 26 (lowest at 6.99%)

Total interest paid: around $2,460

Side by Side

The avalanche saves about $640 more in this example. But the snowball gives you your first win 8 months sooner.

So Which One is Better?

Honestly? I switched between, when I wanted to kill the small debts I used snowball once I got motivated I switched to avalanche.

The avalanche wins on paper every time. But here's the thing — a lot of people who start the avalanche method quit before they ever pay off their first debt. It can take months before you see real progress, and that gets discouraging.

The snowball keeps more people going all the way to the finish line. There's real power in seeing a debt completely disappear from your list.

A simple way to think about it:

Pick snowball if:

• You need early wins to stay motivated

• You've tried paying off debt before and stopped

• The interest rate difference between your debts isn't huge

Pick avalanche if:

• You're disciplined and motivated by numbers

• You have one debt with a much higher rate than the others

• Saving the most money is your top priority

Not sure? Start with snowball. You can always switch later.

The One Thing Both Methods Need

Neither strategy works without one key ingredient, extra payments.

Even $50 extra a month makes a huge difference. Here's a real example:

A $3,200 credit card at 24.99% APR with minimum payments only takes over 15 years to pay off and costs you $4,800+ in interest.

Add $100 extra per month and you're done in under 3 years with only $1,200 in interest.

That's $3,600 saved from just $100 extra. The math is wild.

Where Do You Find Extra Money?

Here are some real ways people find extra cash to throw at debt:

• Cancel subscriptions you don't use anymore

• Stop buying coffee and do it at home.

• Start DYI your car maintenence

• Cook at home a few more times per week

• Sell things you don't use on Facebook Marketplace

• Put your tax refund straight toward debt

• Pick up extra hours or a small side gig

• Ask for a raise if you haven't in a while

Even small amounts add up faster than you think.

See Your Own Numbers

The best way to figure out which strategy works for your situation is to run the numbers with your actual debts.

That's exactly why I built Mydebtplanner because I was tired of searching for a simple, free tool that could clearly tell me when I’d finally be debt free and coming up empty every time. So I decided to build it myself. Now, I’m sharing everything I learned along the way so others don’t have to go through the same struggle

Common Questions

Can I switch from snowball to avalanche partway through? Yes, anytime. Some people start with snowball to build confidence and switch to avalanche once they're in a good rhythm.

What if two debts have the same balance or rate? For snowball — pay the one with the higher rate first. For avalanche — pay the one with the lower balance first so you free up cash sooner.

Should my mortgage be included? Most people focus on credit cards and loans first since they have higher rates. Mortgages usually have lower rates and may have tax benefits too.

What if I can barely make the minimums? Call your creditors first. Many have hardship programs that can lower your rate or payment temporarily. A nonprofit credit counselor can also help if you're in a tough spot.

The Bottom Line

Snowball or avalanche — both work. Both will get you debt free.

The avalanche saves more money. The snowball keeps more people motivated. Neither one matters if you never start.

Pick one today. Run your numbers. Make a plan. And remember — every extra dollar you put toward debt is a dollar that stops working against you.

You can do this.
