Debt Snowball vs Avalanche: Repayment Order and Trade-Offs
Automated technical check: . Scope and review policy
Debt snowball and debt avalanche differ in which debt receives extra payments. The Consumer Financial Protection Bureau describes both approaches: targeting the smallest balance can provide earlier milestones, while targeting the highest rate addresses the most expensive debt first and can reduce interest.
Open a single-debt payoff example. This tool does not simulate repayment ordering across multiple debts.
A concrete ordering example
These illustrative balances deliberately put the highest rate on a different account from the smallest balance. They demonstrate order only, not payoff dates or total savings.
| Debt | Balance | Annual rate |
|---|---|---|
| Card A | $1,200 | 12% |
| Card B | $4,500 | 24% |
| Personal loan | $8,000 | 8% |
Snowball order: Card A → Card B → Personal loan.
Avalanche order: Card B → Card A → Personal loan.
In both approaches, required payments continue on the other accounts. When an account is repaid, its former payment can be redirected to the next target rather than reducing the total repayment budget.
Why no savings figure is shown
Balances and annual rates alone are insufficient to reproduce a repayment schedule. Minimum-payment rules, payment timing, available extra payments, fees, new borrowing and changing rates also matter. A reliable comparison must hold the total budget and assumptions consistent. We have not run a multi-debt simulation here, so we do not publish a dollar saving or a debt-free date for either ordering.
What the tools can calculate
The Loan Payoff calculator estimates one debt's schedule using a fixed payment and optional extras. The Loan Comparison calculator compares two separate amortizing loans by amount, rate and term. Neither is a multi-account snowball/avalanche planner.
For a reproducible $5,000, 24% fixed-rate example with different monthly payments, see the credit-card payoff guide. A real card's daily interest, minimum rules and fees may differ.
Frequently asked questions
What is the difference between snowball and avalanche?
Snowball targets the smallest balance first. Avalanche targets the highest interest rate first. Both keep required payments on the other debts and redirect available extra payments to the target.
Can this calculator compare both methods across several debts?
No. The Loan Payoff calculator models one debt with a fixed payment and optional extras. Loan Comparison compares two separate amortizing loans, not the order of repaying a debt portfolio.
