What it does

• Debt-free month and total interest for both methods
• Payoff order and the month each debt is gone
• How much the avalanche saves vs how fast the snowball gives a first win
• Month-by-month schedules up to 360 months
• Payment tracker with progress bars

Snowball vs avalanche in one minute

Both methods pay the minimum on every debt and put all extra money on one target debt. When it is paid off, its payment rolls onto the next. The only difference is the order:

• Snowball: smallest balance first. You clear a debt sooner, which keeps many people motivated.
• Avalanche: highest interest rate first. Mathematically it pays less interest overall.

What the example in this template shows

With six made-up debts totalling $34,100 and $300 extra per month, the planner computes 38 months to debt-free with the snowball and 37 with the avalanche, and the avalanche saves $274.23 in interest. Both clear a first debt in month 3. Your numbers will differ; the sheet recalculates as soon as you type yours.

What to type in

1. Each debt's current balance, interest rate (APR) and minimum payment.
2. The extra amount you can pay each month on top of all minimums.
3. Then read the Plan tab: debt-free month, total interest and payoff order for both methods.

The schedules assume monthly interest at APR ÷ 12 and the same payments every month. Real statements can differ slightly (daily interest, fees, rate changes). Not financial advice.
