The core rule: order debts from smallest balance to largest. Keep every required minimum current. Send only genuinely available extra money to the smallest active debt.
How the debt snowball works
List every active debt
Record the balance, minimum payment, APR, and due date. Leave recurring household bills out of the payoff order.
Sort by balance
The smallest remaining balance becomes the target. APR does not determine the snowball order.
Pay every minimum
Keep all active accounts current while directing extra money to one target.
Roll the payment forward
When a debt reaches zero, add its old monthly payment to the next target instead of absorbing it into everyday spending.
A six-debt snowball example
| Order | Debt | Balance | Minimum |
|---|---|---|---|
| 1 | Medical bill | $420 | $35 |
| 2 | Store card | $780 | $45 |
| 3 | Personal loan | $2,100 | $110 |
| 4 | Credit card | $4,600 | $145 |
| 5 | Auto loan | $9,800 | $325 |
| 6 | Student loan | $18,500 | $210 |
If $100 extra is available, Debt 1 receives $135 per month. After it is paid, Debt 2 receives its $45 minimum plus the freed $35 and the same $100 extra, for $180 per month. The payment grows as each debt disappears.
Snowball versus avalanche
Snowball
Orders debts by balance. It can produce faster visible wins and free small monthly payments sooner.
Avalanche
Orders debts by APR. The math may show lower total interest, especially when the highest-rate balance is large.
Neither method excuses late essential bills or missing minimums. A hybrid approach can address an urgent high-rate debt first, then return to smallest-balance order.
Minimum payments are not failure. Paying minimums on the non-target debts is part of the method. It protects the plan while one target receives the extra money.
When extra payments are safe
Before sending more to debt, account for the bills assigned to the current paycheck and basic living costs. A small emergency buffer can keep one car repair from going back onto a paid-down card. The math shows the payoff opportunity only after those needs are visible.
Frequently asked questions
What if two debts have the same balance?
Use the higher APR, smaller minimum, or whichever account creates the clearest win as a tie breaker. Consistency matters more than the tie.
Should I close a card after paying it off?
That decision can affect credit utilization and account history. Consider fees, temptation to reuse the card, and your credit goals before deciding.
Can the snowball include BNPL balances?
Yes, if they are debts with remaining balances. List each active plan clearly so small payments do not disappear from view.
