How The Snowball Method Works
Write down all of your debts (except your house) and sort them strictly in order of balance from smallest to largest. Mathematical interest rates do not matter here—we want quick emotional wins.
Make the requisite minimum payments to keep all your big lenders happy. Then, squeeze every single extra dollar you can find in your budget and throw it entirely at the smallest debt at the top of the list.
Once Debt #1 is gone, take its old minimum payment PLUS your extra cash, and aim that massive combined payment straight at Debt #2. Once Debt #2 is gone, roll the entire massive payment to Debt #3.
The Psychology of Debt Elimination
When people first look at debt calculators, they frequently ask: "Why would I pay off a tiny $500 medical bill that has 0% interest instead of my $15,000 credit card with 25% interest? That's mathematically foolish."
The answer lies in human behavior. Harvard Business Review studies have found that consumers who concentrate on paying off accounts with the smallest balances first are significantly more likely to eliminate all their debt eventually. If you try chipping away at a $15,000 credit card for 8 months without seeing it vanish, you lose hope and quit. If you kill off three tiny debts in 3 months, you get an adrenaline rush of success that keeps you fighting.
Snowball vs. Avalanche Comparison
Snowball Method
- Prioritizes balances smallest to largest
- Generates immense psychological motivation
- Frees up cash flow quickly

Avalanche Method

- Mathematically saves more interest money
- Often takes 1-2 years to see the first debt vanish
- Higher abandonment rate by users
Finding "Extra" Cash
The snowball calculator asks for an "Extra Monthly Payment". This is the fuel for your snowball. Without extra money, you are simply treading water against interest charges. Finding this extra money requires setting up a strict zero-based budget, cutting lifestyle expenses (like eating out), selling unused items on eBay, or working a side hustle specifically designed to generate Snowball Fuel.
