Accelerate Your Payoff with the Snowball Method

Our Debt Snowball Calculator is designed to simulate the snowball payoff strategy popular in personal finance counseling. By targeting your smallest debt balance first while maintaining minimum payments on all other accounts, you create quick wins that keep you motivated on your financial journey.

How the Debt Snowball Effect Works

The snowball method focuses on behavioral modification rather than pure mathematics. You list your debts in order of balance size:

  1. Maintain minimum payments on all debts except the smallest.
  2. Throw all extra money (from savings, side hustles, etc.) at the smallest debt until it is gone.
  3. Take the entire payment from the paid-off smallest debt and add it to the next smallest debt.

This creates a snowball effect where your payment size grows larger with every eliminated account. For consumer guidelines on credit and debt relief options, check the Consumer Financial Protection Bureau (CFPB) website.

Worked Numerical Example

Let's look at a debt of $15,000 at a 10.0% interest rate over a 5-year term, with an extra allocation of $200/month:

Understanding Extra-Payment Payoff Math

What is the debt snowball method?+

The debt snowball method is a debt payoff strategy where you pay off your debts in order from smallest balance to largest balance, regardless of the interest rate. Once a smaller debt is paid, its entire payment rolls into the next smallest.

Why does the debt snowball work?+

The debt snowball works because of human psychology. Paying off a small debt completely provides a quick win and creates a sense of momentum, helping you stay committed to your debt-free plan over the long term.

What is the difference between snowball and avalanche?+

The debt snowball prioritizes debts by balance size (smallest first) to build psychological momentum. The debt avalanche prioritizes debts by interest rate (highest rate first) to minimize the amount of interest paid.

Should I do debt snowball or debt avalanche?+

If you need quick wins to stay motivated, choose the Debt Snowball. If you want to pay the least amount of interest and save the most money mathematically, choose the Debt Avalanche.

Can I use extra payments with the debt snowball?+

Yes! Extra monthly contributions are added to the minimum payment of your smallest debt first, accelerating the snowball process and clearing your first debt much faster.
