What is the Debt Avalanche method?

The Debt Avalanche method prioritizes paying off debts with the highest interest rates first, while making minimum payments on all other debts. Once the highest-rate debt is paid off, you roll that payment into attacking the next highest-rate debt. This method minimizes total interest paid and is mathematically optimal.

What is the Debt Snowball method?

The Debt Snowball method prioritizes paying off the smallest balance debts first, regardless of interest rate. This creates quick psychological wins that can build momentum and motivation. While you may pay slightly more in interest, the behavioral benefits often help people stick with their debt payoff plan.

Which debt payoff method should I choose?

If you're motivated by math and saving money, choose Avalanche. If you need quick wins to stay motivated, choose Snowball. Our calculator shows you exactly how much each method costs so you can make an informed decision. Some people even switch between methods as their situation changes.

What is payment rolling?

Payment rolling (or debt stacking) is when you take the monthly payment from a paid-off debt and add it to your payment for the next debt in line. This accelerates your payoff over time because your effective payment grows as each debt is eliminated.

How accurate are debt payoff calculations?

Our calculations assume fixed interest rates and consistent monthly payments. In reality, credit card rates can change, and you might make extra payments some months. Use these projections as a planning tool and roadmap, not as a guarantee.

What if I can only afford minimum payments?

Even with minimum payments only, having a strategy helps. The calculator shows your projected timeline. If it seems too long, look for ways to reduce expenses or increase income to add even $25-50 extra per month—small amounts compound significantly over time.
