Frequently Asked Questions

What is the debt snowball method?
The debt snowball method focuses on paying off your smallest debts first, regardless of interest rate. You make minimum payments on all debts, then put any extra money toward the smallest balance. When that debt is paid off, you roll its payment to the next smallest, creating a 'snowball' effect.
What is the debt avalanche method?
The debt avalanche method focuses on paying off debts with the highest interest rates first. You make minimum payments on all debts, then put any extra money toward the highest-APR debt. This method saves the most money on interest over time but may take longer to see your first debt fully paid off.
Which debt payoff method is better: snowball or avalanche?
The avalanche method mathematically saves you the most money because it targets high-interest debt first. However, the snowball method provides psychological wins by eliminating small debts quickly, which helps many people stay motivated. The best method is the one you'll stick with consistently.
How does a debt payoff calculator work?
A debt payoff calculator simulates both the snowball and avalanche methods using your debt details (balance, APR, minimum payment) plus any extra monthly payment you can afford. It calculates total interest paid, months to debt-free, and generates a visual comparison chart so you can see which method works best for your situation.
