Debt Snowball vs Avalanche: Which Loan Should You Clear First in India?

Which debt should I pay off first? Neither method wins for everyone. The avalanche method — paying the costliest debt first — minimises total interest. The snowball method — paying the smallest balance first — can feel more motivating. In our ₹3.3 lakh Indian illustration, both took 15 months, but the avalanche cost about ₹8,305 less in interest.

A credit card bill of ₹1 lakh, a personal loan of ₹2 lakh, a buy-now-pay-later balance of ₹30,000 — and one fixed monthly budget of ₹25,000 for all three. This is a situation lakhs of young Indian earners recognise, and it forces one question: which debt gets the extra money? Two strategies answer it differently. The debt avalanche attacks the highest interest rate first. The debt snowball attacks the smallest balance first. Generic explainers stop at definitions; this article runs both methods month by month on a fully worked Indian example.

What the Two Methods Actually Are

The avalanche method ranks debts by interest rate, highest first. Every spare rupee goes to the costliest debt while the others get only minimums; once it is gone, its entire payment rolls into the next-costliest debt. Interest compounds fastest on the highest-rate balance, so killing it first stops the most expensive growth. The snowball method ranks debts by balance, smallest first, with the same rollover mechanics. Its argument is psychological: an early "debt cleared" win can keep a borrower motivated through a long payoff journey. Neither method invents money — the monthly outgo is identical in both. Only the order changes, and that can shift the total interest bill by thousands of rupees.

The Indian Scenario: Three Debts, One ₹25,000 Budget

The illustration is deliberately ordinary: Debt A — Credit card: ₹1,00,000 at 42% p.a. (3.5% per month). Indian cards typically charge 3.35%–3.75% per month, roughly 40%–45% annualised. Minimum due: 5% of the outstanding balance. Debt B — Personal loan: ₹2,00,000 at 12% p.a. (1% per month), within the typical 10%–15% p.a. range for salaried borrowers. Debt C — BNPL: ₹30,000 at 0% — interest-free only if every instalment is paid on time; late fees can apply. The monthly debt budget is ₹25,000. Each month, pay every debt's minimum, then put every remaining rupee toward the target debt. The simulation's assumptions, stated plainly: 1. The credit card minimum is 5% of the outstanding balance (or the month's interest, whichever is higher). 2. The personal loan's minimum is that month's interest only, until it becomes the target debt. 3. The BNPL carries no interest and no minimum. 4. Interest rates stay constant, no fees are charged, and no new borrowing happens. 5. GST on card interest (18%) is excluded, so real-world card costs would be higher than shown. 6. All figures are rounded to the nearest rupee. This is an illustration of method mechanics, not a prediction. Want to test your own numbers? Try the live calculator below.

The Avalanche Run: Costliest First

Payoff order: credit card → personal loan → BNPL. Month 1 sets the pattern: the card accrues ₹3,500 in interest and the personal loan ₹2,000. After minimums of ₹7,175, ₹17,825 attacks the card, cutting it from ₹1,00,000 to ₹80,500 in a single month. Key checkpoints along the avalanche path: End of month 1: card ₹80,500; personal loan ₹2,00,000; BNPL ₹30,000. End of month 3: card ₹39,429; personal loan ₹2,00,000; BNPL ₹30,000. Month 5: credit card cleared — the 42% bleed stops here. Month 6 onwards: nearly the full ₹25,000 attacks the personal loan. End of month 10: personal loan ₹77,876. Month 14: personal loan cleared. Month 15: BNPL cleared — debt-free. Total interest paid across the whole journey: approximately ₹29,528.

The Snowball Run: Smallest First

Payoff order: BNPL → credit card → personal loan. The ₹30,000 BNPL is the first target: month 1 cuts it to ₹12,175 and month 2 wipes it out — an early psychological win. Meanwhile the credit card keeps compounding at 3.5% a month, nearly untouched. Key checkpoints along the snowball path: End of month 1: card ₹98,325; personal loan ₹2,00,000; BNPL ₹12,175. Month 2: BNPL cleared — one debt gone. End of month 4: card ₹50,614. Month 7: credit card cleared — two months later than the avalanche. End of month 10: personal loan ₹1,14,516 (versus ₹77,876 under the avalanche). Month 15: personal loan cleared — debt-free. Total interest paid: approximately ₹37,833.

The Verdict: Same Finish Line, Different Price Tag

Here is the comparison, side by side: Months to debt-free: 15 (avalanche) vs 15 (snowball) — a tie in this scenario. Total interest paid: ~₹29,528 (avalanche) vs ~₹37,833 (snowball). Interest difference: ~₹8,305 more under the snowball method. First debt cleared: month 5, the card (avalanche) vs month 2, the BNPL (snowball). The timeline tie surprises many people: the ₹25,000 budget is large relative to the total debt, so the budget — not the method — sets the pace. The interest gap is driven by one fact: under the snowball, the 42% card balance survives two months longer, and 3.5%-a-month compounding on ~₹1 lakh costs roughly ₹3,000–3,500 in interest every month it survives. The trade-off, stated neutrally: the avalanche minimised interest here, while the snowball delivered its first "debt cleared" moment three months earlier. With a huge rate gap — 42% vs 12% vs 0% — the cost of chasing the psychological win is large; with similar rates, the gap shrinks and motivation carries more weight. Which matters more is a personal judgement call.

India-Specific Things to Know Before Choosing an Order

The minimum-due trap is the real enemy. Paying only the 5% minimum due on a credit card barely dents the principal at 3.5% monthly interest. Both methods work only because payments run far above the minimums. Minimum-only repayment is the slowest, costliest path under either method. The true card cost is higher than 42%. GST at 18% applies to the interest charged, pushing the effective annual burden toward 50% on revolving balances — and the simulation above excludes GST. Prepaying a floating-rate loan now costs nothing extra. Under the RBI's (Pre-payment Charges on Loans) Directions, 2025 — effective for loans sanctioned or renewed on or after 1 January 2026 — regulated lenders cannot levy prepayment or foreclosure charges on floating-rate loans. Fixed-rate loans are treated differently, so the loan agreement and Key Facts Statement remain the documents to check. "Settled" and "Closed" are not the same word on your credit report. Repaying a loan in full gets it marked "Closed" — no negative signal. Negotiating a part-payment deal gets it marked "Settled", a negative event that can stay visible on the report for up to around seven years. For borrowers choosing a payoff order, the practical lesson is simple: clearing debts in full protects the credit record in a way settlements do not. BNPL is interest-free only on time. A missed instalment can trigger late fees and, with some providers, credit-bureau reporting — that is how small balances become expensive ones.
