# Debt Avalanche Calculator
The debt avalanche method attacks your highest-interest debt first — regardless of balance. Mathematically, this is always the cheapest way to eliminate debt because it minimizes the interest that compounds against you every month.
How It Works
- List all debts with APRs — know the interest rate on every balance
- Order from highest APR to lowest — this is your payoff sequence
- Pay minimums on everything — throw every extra dollar at the highest-rate debt
- Cascade down the list — when one debt is paid off, redirect its payment to the next

FAQs
Is avalanche guaranteed to save me money?
Yes — mathematically, paying highest-APR debt first minimizes total interest. The size of the savings depends on your specific debts.
What if I need motivation?
If avalanche feels too slow (your first payoff might take 6-12 months), consider paying off your smallest debt first for the win, then switching to avalanche. This hybrid approach works well.
When should I NOT use avalanche?
Only when you know you'll give up before seeing progress. Snowball has higher completion rates.
