Debt Avalanche vs Debt Snowball: Which Payoff Strategy Works?

If you have multiple debts — credit card, personal loan, home loan — you need a systematic payoff strategy. Two methods dominate: avalanche and snowball.

Debt Avalanche

Pay minimum on all debts. Throw every extra rupee at the highest-interest debt first. Once it is paid, redirect to the next highest.

Mathematically optimal. You pay the least total interest. Typically best for disciplined savers.

Debt Snowball

Pay minimum on all debts. Throw every extra rupee at the smallest-balance debt first. Once it is paid, redirect to the next smallest.

Psychologically superior for many people. Quick wins build momentum. Research shows higher completion rates for people who use snowball vs avalanche — because behavior matters more than math when you are in debt.

The Numbers

On ₹10 lakh total debt with a ₹30,000/month repayment capacity:

• Avalanche typically saves ₹40,000–80,000 in interest
• Snowball may take 2–4 months longer

The gap narrows as interest rates converge. If your highest-interest debt also has the smallest balance, both methods are the same.

When to Use Which

• Avalanche: You are motivated, disciplined, and the interest rate spread across debts is large (credit card at 36% vs home loan at 8.5%).
• Snowball: You have multiple small debts that feel overwhelming. The psychological relief of closing accounts matters to you.

High-Interest First Is Non-Negotiable

Regardless of method: credit card debt at 36–42% APR must be eliminated before any discretionary investing. The guaranteed return of paying off 36% debt exceeds any equity return.
