Paying off debt can feel overwhelming, especially when you have multiple balances with different interest rates and minimum payments. To make things easier, we created a Debt Snowball & Avalanche Calculator — a free online tool that helps you plan your debt repayment, see how much interest you’ll save, and get a clear month-by-month plan.

Whether you prefer the Debt Snowball method (tackling the smallest balance first for quick wins) or the Debt Avalanche method (targeting the highest interest rate first for maximum savings), this calculator gives you a clear roadmap to becoming debt-free.

How the Debt Snowball & Avalanche Calculator Works

The tool takes your debt balances, interest rates, minimum payments, and extra monthly payment amount. Then, it simulates your repayment schedule using the method you choose.

It shows:

Total debt
Total minimum payments
Payoff time (months and years)
Total interest paid
Total amount paid
Interest and time saved compared to paying only minimums
Payoff order of debts
A monthly payment plan for the first 12 months

Step-by-Step Guide to Using the Calculator

- Even $50 extra can save you hundreds in interest.
Add Your Debts
- For each debt, fill in:
  - Name (e.g., “Credit Card 1,” “Auto Loan”)
  - Balance ($)
  - Minimum monthly payment ($)
  - Interest rate (%)
- You can list up to 5 debts.

Example: Snowball vs. Avalanche

Scenario:
You have:

Credit Card 1: $2,500 balance, $75 min payment, 18.99% interest
Personal Loan: $5,000 balance, $150 min payment, 12.5% interest
Credit Card 2: $1,200 balance, $40 min payment, 22.99% interest
Auto Loan: $8,000 balance, $250 min payment, 6.5% interest
Extra payment: $200/month

Debt Snowball Method:

Pay off Credit Card 2 first (smallest balance), then Credit Card 1, Personal Loan, and finally Auto Loan.
Motivational “quick wins” from knocking out debts early.

Debt Avalanche Method:

Pay off Credit Card 2 first (highest interest), then Credit Card 1, Personal Loan, and finally Auto Loan.
Saves more on interest but may take longer before your first debt is gone.

With both methods, your debt-free date will come much sooner compared to paying only minimums — and you’ll save thousands in interest.

When to Use Debt Snowball vs. Debt Avalanche

Debt Snowball is best if you:
- Need early motivation and quick psychological wins
- Have trouble staying consistent with debt repayment
- Don’t mind paying a little more interest for momentum
Debt Avalanche is best if you:
- Want to save the most money in interest
- Can stay disciplined even without early “small wins”
- Have high-interest debt that is costing you the most

Extra Tips for Using the Calculator Effectively

Re-calculate after each major change. If you pay off a debt early or get extra income, update the numbers.
Set realistic extra payments. It’s better to commit to an amount you can maintain.
Consider debt consolidation. If your interest rates are very high, explore whether consolidation could lower them.
Track progress monthly. Staying aware of your payoff timeline keeps motivation high.
