You have three debts and one monthly budget to throw at them. Do you clear the smallest balance first for a quick win, or attack the highest interest rate first to pay the least? These two methods have names: the debt snowball and the debt avalanche. Here is how they actually compare, using one worked example.
The two methods in one minute
Debt snowball: pay the minimum on every debt, then put all extra money on the smallest balance. When it is cleared, roll that whole payment onto the next smallest.
Debt avalanche: pay the minimum on every debt, then put all extra money on the debt with the highest interest rate. When it is cleared, roll that payment onto the next highest rate.
A worked example
Suppose you carry three debts and can pay ₹15,000 a month in total towards them:
| Debt | Balance | Interest rate (per year) | Minimum payment |
|---|---|---|---|
| Credit card A | ₹60,000 | 42% | ₹3,000 |
| Credit card B | ₹30,000 | 36% | ₹1,500 |
| Personal loan | ₹1,00,000 | 14% | ₹3,500 |
Minimums add up to ₹8,000, so ₹7,000 a month is the extra. Here is what happens with no new borrowing, interest charged monthly, and the extra always aimed at one target:
| Snowball (smallest balance first) | Avalanche (highest rate first) | |
|---|---|---|
| Order of attack | Card B, then Card A, then the loan | Card A, then Card B, then the loan |
| Time to be debt-free | 15 months | 15 months |
| Total interest paid | About ₹29,200 | About ₹28,200 |
These numbers come from a simple month-by-month model, so treat them as an illustration rather than a quote from any lender. The honest takeaway: the avalanche wins on cost, but here only by roughly ₹1,000, and both methods finish in the same number of months.
Why the gap is so small here
The two methods only differ in which debt gets the extra money first. In this example both credit cards carry very high rates (42% and 36%) and are cleared early either way, so the order barely changes the total interest. The gap grows when your balances and rates are spread further apart, for example a large high-rate balance sitting behind a small low-rate one.
So which should you choose?
On pure arithmetic, the avalanche never costs more interest than the snowball. But the best method is the one you will actually stick to. The snowball clears whole debts sooner, which gives early wins and can keep you motivated. If the interest difference is small, as it is above, the snowball’s motivation can be worth more than the extra ₹1,000. If your highest-rate debt is also large, the avalanche usually saves meaningfully more and is the better default.
Whichever you pick, three habits matter more than the method: stop adding new spending to the cards, keep paying the minimum on every debt so nothing goes delinquent, and put every spare rupee on your chosen target.

FAQ
Is the debt avalanche always cheaper than the snowball?
In total interest, yes: by definition it targets the most expensive debt first, so it never costs more. The difference can be small, as in the example above.
Which method is faster?
Neither is guaranteed faster. In the example both took 15 months. The snowball clears individual debts sooner, while the avalanche reduces total interest sooner.
Should I include my home loan?
Usually not. Home loans carry much lower rates and tax benefits, so most people focus these methods on credit cards and personal loans.
What if two debts have the same interest rate?
Then pay the smaller balance first. It costs the same in interest and clears a debt sooner.
