DebtZero
Add every balance, set an extra monthly payment, and compare snowball vs. avalanche side by side.
Paying only the minimum on a $5,000 balance at 22% APR can take 25+ years and cost more in interest than the original balance. Doubling the payment usually cuts payoff time by more than half.
Avalanche (highest interest rate first) minimizes total interest paid. Snowball (smallest balance first) clears individual debts faster, which can build momentum even if it costs a little more overall.

Snowball vs. avalanche
Total remaining balance across all debts, month by month.
Snowball
Smallest balance first
Avalanche
Highest APR first
Snowball builds momentum by clearing small debts fast. Avalanche targets the highest interest rate first — it usually costs less overall. Both pay every minimum every month; only where the extra payment goes differs.

Avalanche finishes first: Avalanche saves the most interest
Both strategies use the exact same monthly budget — minimums plus your extra payment. The only difference is which debt the extra goes to first, which is why the total time and interest can differ even though you're paying the same amount each month.
