A Simple, Free, Debt Repayment Calculator

Ready to kill your debt? This tool will help you decide between a snowball or an avalanche to get the job done.


Many a YNABer has shown up on our virtual doorstep, motivated by the desire to escape debt. Big debt, little debt, credit card debt, student loan debt, medical debt. All kinds of debt.

And your budget is a critical piece of the picture—strategically giving every dollar a job is the first step towards living within your means and digging yourself out of the hole. If you’ve ever attended YNAB’s classes, Aggressive Debt Pay Down or Master Credit Cards with your Budget, then you know that there’s no trick to debt repayment, it’s all about priorities. And, apparently, snow …

Snowball vs. Avalanche

There are two common strategies for erasing debt, and there’s much debate about which is better:

  • The Snowball Method: With the snowball approach, you pay off your debts in order of size (starting with the smallest). Pay the monthly minimum for each loan, putting any extra dollars in your budget towards the smallest loan. Continue this process until all loans are paid.
  • The Avalanche Method: To create an avalanche, once again, you pay the minimum for each loan. The difference is, you allocate your extra dollars towards the loan with the highest interest rate.

Some people, notably Dave Ramsey, suggest that the snowball approach will motivate you to keep going with early “wins” as you pay off your smaller debts. Others argue that the avalanche approach saves you money in the long run because you’ll pay less interest.

So which way is better? As with most things, the answer is, it depends.
