Frequently asked questions
What is the debt snowball method? ▼
The debt snowball method pays off debts from smallest to largest balance. As each debt is cleared, its payment rolls into the next. This provides psychological wins that motivate continued repayment.
What is the debt avalanche method? ▼
The debt avalanche targets the highest interest rate first. This minimizes total interest paid and is mathematically optimal, though it may take longer to see the first debt disappear.
Snowball vs avalanche — which is better? ▼
The avalanche saves more money. The snowball provides faster psychological wins, which can help with motivation. If consistency is difficult, the snowball may be more effective in practice despite costing more.
How does an extra monthly payment affect payoff time? ▼
Even $100–$200 extra per month dramatically reduces total interest and payoff time. Use the calculator to see exactly how much you'd save with your specific debts.
