The debt snowball method pays off your smallest balance first, regardless of interest rate. Once the smallest debt is paid off, you roll that payment to the next smallest. This creates psychological momentum — quick wins that keep you motivated. Research by Harvard Business School found that people who use the snowball method are more likely to actually eliminate all their debt.
What is the debt avalanche method?
The debt avalanche method targets your highest interest rate debt first, regardless of balance. This minimizes total interest paid over time and is mathematically optimal. However, if your highest-rate debt also has a large balance, it can take many months before you see your first debt paid off — which can reduce motivation for some people.
Which debt payoff method saves more money?
The avalanche method always saves more money in total interest, sometimes significantly. On a typical debt load of $15,000 across 4 accounts, the avalanche can save $1,200–$2,500 compared to the snowball. However, research shows people are more likely to actually complete the snowball method because of the psychological wins from paying off small debts quickly. The best method is the one you will actually stick with.
How much extra should I pay each month to get out of debt faster?
Even $50–$100 extra per month can dramatically accelerate your payoff date. On a $10,000 debt at 20% APR with $250 minimum payments, adding $100/month cuts payoff time from 62 months to 41 months and saves over $2,000 in interest. The key is consistency — even small extra payments compound significantly over time.
Should I pay off debt or invest?
The general rule: if your debt interest rate is higher than your expected investment return (roughly 7–10% for index funds), pay off the debt first. Credit card debt at 20%+ APR should almost always be paid off before investing beyond your employer's 401(k) match. Low-rate debt like student loans at 4–6% is a closer call and depends on your personal risk tolerance.
What if I can't afford the minimum payments?
If you cannot afford minimum payments, contact your creditors immediately. Many offer hardship programs, temporary payment reductions, or interest rate reductions. You can also consider working with a nonprofit credit counseling agency (look for NFCC-certified counselors) for a debt management plan. The Debt Negotiation Scripts guide covers how to have these conversations effectively.
