Why Use This Calculator
Choosing the right debt payoff strategy can save you thousands in interest and get you debt-free months or years sooner. The snowball method provides quick psychological wins by eliminating small debts first, while the avalanche method mathematically minimizes total interest. This calculator shows you exactly how each method performs with your specific debts.
Frequently Asked Questions
The snowball method targets the smallest balance first for quick wins and motivation. The avalanche method targets the highest interest rate first, saving the most money. Both use the same extra payment — only the order of payoff differs. Choose based on whether you need motivation (snowball) or math optimization (avalanche).
Pay as much as you can afford while still covering essential expenses. Even small extra payments make a big difference. For example, an extra $100/month on $15,000 of credit card debt at 20% APR can save over $4,000 in interest and pay off the debt 2+ years earlier.
This calculator works best for high-interest consumer debt like credit cards, personal loans, and auto loans. Mortgages typically have lower rates and longer terms, so they're usually handled separately. Focus your extra payments on debts with the highest interest rates first.
