If you owe money across multiple cards or loans, the order you pay them off in changes both how much you pay overall and how likely you are to stick with the plan. There are two dominant strategies, and they optimize for different things.
Debt avalanche: minimize total interest
The avalanche method sorts your debts by interest rate, highest to lowest. You pay the minimum on everything except the highest-rate debt, which gets every spare rupee until it's gone. Then you roll that entire payment into the next-highest-rate debt, and so on.
This is mathematically optimal — for any fixed extra payment amount, the avalanche method always produces the lowest total interest paid and, usually, the fastest overall payoff. A credit card at 36% APR is costing you far more per rupee of balance than a personal loan at 12%, so clearing the card first is objectively the cheaper path.
Debt snowball: minimize time-to-first-win
The snowball method sorts debts by balance, smallest to largest, ignoring interest rate entirely. You throw every spare rupee at the smallest balance first, then roll that payment into the next-smallest, and so on.
This is not the cheapest method on paper — you'll typically pay somewhat more in total interest than with the avalanche. But it produces a payoff win faster, often within the first month or two, because small balances disappear quickly. That early win is the entire point: behavioral research on debt payoff (popularized by Dave Ramsey, among others) consistently finds that people are more likely to complete a payoff plan when it delivers visible progress early, rather than the largest, slowest-moving debt sitting untouched for a year.
The actual difference is usually small
For most realistic debt loads (a few cards plus maybe one personal loan), the total interest difference between snowball and avalanche is a few thousand rupees, not lakhs — because you're paying off everything within a year or two either way, and the gap only compounds meaningfully over long timelines. The real deciding factor is which one you'll actually finish.
A simple way to decide
- If your highest-rate debt is also your smallest balance, there's no tradeoff — do that one first under either method.
- If you've started and abandoned a debt payoff plan before, take the snowball. The early momentum is worth more to you than the interest savings.
- If you're disciplined about sticking to plans regardless of visible progress, take the avalanche and save the extra interest.
- Either way, keep making minimum payments on every other debt — missing even one minimum payment can trigger penalty APRs and hurt your credit score more than the interest difference between the two strategies.
Model your own payoff
Our Credit Card Payoff Calculator lets you plug in your actual balances, rates, and extra payment amount to see exactly how many months either strategy takes and how much interest each one costs — so you can decide with real numbers instead of a rule of thumb.
