Debt Snowball Calculator
Pay off the smallest balance first, then roll those freed payments to the next — see exactly when each debt gets eliminated and when you'll be debt-free.
Snowball method: Pay minimums on all debts, then direct all extra money at the smallest balance first. Once it's paid, roll that payment to the next smallest.

How the calculation works
Step 1: List debts from smallest to largest balance.
Step 2: Pay minimums on all debts every month.
Step 3: Direct all extra money at the smallest balance until it's gone.
Step 4: Once a debt is paid, roll its freed payment to the next smallest — the "snowball" grows with each payoff.
The snowball method is psychologically powerful because it produces quick wins. It costs slightly more in interest than the avalanche method but keeps more people on track to completion.
Frequently Asked Questions
- Behaviour matters as much as math. Paying off a debt completely creates a motivational win that keeps people committed. Research shows the snowball method leads to higher debt-elimination success rates than the mathematically optimal avalanche method.
- Snowball: smallest balance first. Avalanche: highest interest rate first. Avalanche saves more total interest. Snowball delivers quicker wins. For most people with moderate debt, the snowball is the better choice because sustained motivation prevents giving up.
- Most debt advice excludes the mortgage from the snowball — focus on consumer debts (credit cards, personal loans, car loans, student loans) first, then tackle the mortgage separately once other debts are eliminated.
- Pay off the one with the higher interest rate first among equal balances — this is a hybrid approach that respects the snowball logic while slightly reducing interest cost. This calculator orders strictly by balance.
- Even $50–100/month extra makes a significant difference. More is better — consider selling unused items, taking on extra hours, or cutting discretionary spending temporarily. The faster the first debt falls, the bigger the snowball grows.
