Frequently Asked Questions: Debt Payoff & Credit Card Payoff Calculator

Answers to common questions regarding inputs, calculations, and mathematical methodology.

What is the difference between Debt Avalanche and Debt Snowball?

Debt Avalanche targets debts with the highest interest rate (APR) first, which saves you the maximum amount of money in total interest. Debt Snowball targets debts with the smallest balance first, giving you faster psychological wins as accounts reach zero.

How does the debt rollover (snowball effect) work?

When an individual debt or card is paid off, its required minimum payment is not spent—it is automatically rolled over and added to the payment of the next priority debt, accelerating your progress exponentially over time.
