How It Works

Snowball or Avalanche?

❄️

Debt Snowball

Pay smallest balances first. Each account you close gives you a psychological win that keeps you going.

  • Best for motivation and momentum
  • Win quick — close small debts in weeks
  • The method Dave Ramsey recommends

🏔️

Debt Avalanche

Attack highest interest rates first. You pay the least total interest and get out of debt faster.

  • Mathematically optimal — lowest total cost
  • Best when high-rate debts are large
  • Ideal if you're disciplined and numbers-driven

The bottom line: A Harvard Business Review study found snowball leads to higher completion rates because small wins build momentum. But avalanche saves more money — period. The best method is whichever one you'll actually stick with for 12+ months.

Common Questions

FAQ

How accurate is this calculator?
It uses standard amortization formulas. Actual amounts may vary based on compounding, fees, and payment timing. Use it as a planning tool.
Which method do experts recommend?
Dave Ramsey advocates snowball for motivation. Most financial planners recommend avalanche for math efficiency. Choose what keeps you going.
Should I stop investing to pay off debt?
If APR is above 6-7%, prioritize payoff. Low-rate mortgages under 4% may be worth keeping while investing. Always keep a $1K+ emergency fund.
How much extra should I put toward debt?
Start with $50-100/month if possible. Any consistent amount helps. Redirect bonuses, tax refunds, and side income to highest-priority debt.
Will paying off debt hurt my credit score?
Short-term: closing accounts may slightly lower it. Long-term: lower utilization + perfect payments far outweigh this. Scores usually improve in 6-12 months.
Can I use this for student loans?
Yes! Enter each loan separately. Federal student loans have special payoff options — check with your servicer before changing payments.
