Tackling EMIs and High-Interest Debt: Snowball vs. Avalanche in India

Managing Home Loans, Car Loans, and Dangerous Credit Card Rollovers (36–42% APR)

1. The Silent Menace of Revolving Credit in India

Credit card penetration in India has surged with co-branded cards and UPI integration. However, many users inadvertently fall into the "Minimum Amount Due" trap. What banks promote as an affordable monthly concession actually triggers finance charges of 3.0% to 3.75% per month (equivalent to 36% to 45% APR), compounding daily, with 18% GST levied on top of the interest accrued.

Furthermore, revolving an unpaid balance revokes the standard 45-day interest-free grace period on all subsequent purchases, instantly creating a vicious cycle of compound debt.

2. The Avalanche Method (Mathematical Optimization)

Under the Avalanche methodology, you list all your debts in descending order of interest rate:

1. Credit Card Unpaid Balance (~42% p.a.)
2. Instant Personal Loan (~14–18% p.a.)
3. Used Car / Two-Wheeler Loan (~11–13% p.a.)
4. Home Loan (~8.5–9.25% p.a.)

You allocate strictly the minimum dues across all accounts, but direct every single surplus rupee toward the top obligation. Once cleared, you roll the entire payment capacity into the second highest. This minimizes total interest paid to lenders over time.

3. The Snowball Method (Behavioral & Psychological Mastery)

Finance is behavioral rather than purely mathematical. If you feel overwhelmed by multiple collection notices, list debts by smallest outstanding balance regardless of interest rate. Liquidating a small ₹15,000 balance in 30 days provides an immediate dopamine surge, eliminates an entire monthly statement, and simplifies your mental dashboard.
