# Snowball or avalanche: which way to clear several debts?

> Pay the smallest balance first, or the highest interest first? People argue about it online as if one answer is right. We ran the same four debts through both methods. The gap was ₹1,289. The real lesson is somewhere else.

You have four debts and a little extra money each month. Every rupee you add can only go to one of them. Which one should get it? There are two famous answers, and they have two famous nicknames: **snowball** and **avalanche**.

> **In short**
> - **Snowball**: pay the smallest balance first. **Avalanche**: pay the highest interest rate first.
> - Avalanche never costs more interest. Snowball often costs only a little more and gives quicker wins.
> - In our test both finished in 27 months and the interest differed by ₹1,289 on ₹3.2 lakh of debt.
> - Whatever you pick, keep paying the **full total** each month, even after a debt is cleared.

## The two methods in one picture

**Same money, different order**

| Snowball | Avalanche |
| --- | --- |
| Smallest balance first | Highest rate first |
| Clears a whole debt quickly | Cuts interest fastest |
| Fewer bills to track sooner | Mathematically the cheapest |
| Builds momentum and motivation | First win can take longer |
| May cost a bit more interest | Needs patience if the top-rate debt is large |

*Both methods pay the **minimum** on every debt. They differ only in where the extra money goes.*

## Our four debts

To compare fairly we need one set of debts. Here is the example used for everything below. Interest is charged monthly at one twelfth of the yearly rate, and every month we pay the minimums plus an extra ₹5,000, so ₹14,100 goes out in total.

| Debt | Balance | Interest a year | Minimum payment |
| --- | --- | --- | --- |
| Card A | ₹20,000 | 36% | ₹600 |
| Card B | ₹60,000 | 24% | ₹1,500 |
| Personal loan | ₹1,50,000 | 14% | ₹4,000 |
| Bike loan | ₹90,000 | 10% | ₹3,000 |

*Total owed: ₹3,20,000. Total minimums: ₹9,100. Add ₹5,000 extra and the monthly budget is ₹14,100.*

> **A warning inside the table:** Card A's minimum is ₹600. Its monthly interest is 3% of ₹20,000, which is also **₹600**. Pay only the minimum and the balance never moves. This is how a card can stay on your books for years while you pay on time every month.

**Where your first ₹14,100 goes**

|  | Share |
| --- | --- |
| Interest charged this month | ₹4,300 |
| Actually reduces what you owe | ₹9,800 |

*Almost a third of month one goes to interest. Most of it is from the card at 36 percent and the personal loan.*

## How each method plays out

**Snowball** orders by balance: Card A (₹20,000), Card B (₹60,000), Bike loan (₹90,000), Personal loan (₹1,50,000). **Avalanche** orders by rate: Card A (36%), Card B (24%), Personal loan (14%), Bike loan (10%). In our example the first two are the same in both lists, which is why the early months match exactly.

**When each debt disappears**

| When | What |
| --- | --- |
| Month 4 | Card A is gone. Both methods. It is both the smallest and the most expensive. |
| Month 13 | Card B is gone. Both methods. Its old minimum now joins the pile. |
| Month 20 | Snowball clears the bike loan. Avalanche is still working on the personal loan. |
| Month 25 | Avalanche clears the personal loan. Snowball is still paying it, with the bike loan already finished. |
| Month 27 | Debt-free either way. Snowball finishes the personal loan. Avalanche finishes the bike loan. |

*Snowball has three debts cleared by month 20. Avalanche has two. That is the motivation difference, in a calendar.*

**Total debt left, month by month (thousand rupees)**

| Months | Snowball | Avalanche |
| --- | --- | --- |
| 0 | 320000 | 320000 |
| 3 | 290000 | 290000 |
| 6 | 258200 | 258200 |
| 9 | 224800 | 224800 |
| 12 | 189800 | 189800 |
| 15 | 153200 | 153100 |
| 18 | 115500 | 115200 |
| 21 | 76800 | 76100 |
| 24 | 36700 | 35600 |
| 27 | 0 | 0 |

*The two lines are nearly on top of each other. By month 24 avalanche is ahead by about ₹1,100, and then both reach zero in the same month.*

**Total interest paid until debt-free**

|  | Interest |
| --- | --- |
| Snowball | ₹55,877 |
| Avalanche | ₹54,588 |

*Avalanche saves ₹1,289, about 2.3 percent of the interest. Real, but small next to the bigger choices below.*

## When the choice does matter

Our debts were close in size and the biggest rate belonged to the smallest balance, so the two methods barely differed. The gap grows when the **largest** balance carries the **highest** rate. Then snowball leaves the expensive debt for last and you pay its interest for much longer. If you have a big loan at 30 percent and several small ones at 10, avalanche can save noticeably more.

**Pick by your situation**

| Box | What it means |
| --- | --- |
| Rates are all similar | Snowball is nearly free. Take the quick wins. |
| One debt is far costlier | Avalanche. Attack it first, whatever its size. |
| You tend to give up | Snowball. A plan you finish beats a perfect plan you drop. |
| Small balance and top rate | Both methods agree. Start there. |

*If you cannot decide, begin with the debt that has the highest rate **and** a small balance. It is usually the best of both worlds.*

## Five rules that matter more than the method

1. **Never miss a minimum.** A late fee or penalty rate can wipe out a month of progress.
2. **Keep the total payment fixed.** When a debt is cleared, roll its old minimum into the next target. This is the actual snowball.
3. **Stop adding new debt.** Paying down a card while spending on it is a treadmill.
4. **Keep a small emergency cushion.** Without it, the next surprise bill goes back on the card.
5. **Ask about cheaper money.** A balance transfer or a consolidation loan at a lower rate can help, but check the fees and do the maths first.

> **Make it visible:** Write the debts on a sheet with the payoff month beside each. Cross them off as they go. It sounds childish and it works, because the payoff date is more motivating than the balance.

## Frequently asked questions

### What is the difference between the debt snowball and the debt avalanche?

The snowball pays extra money to the smallest balance first. The avalanche pays it to the debt with the highest interest rate first. Both pay the minimum on every other debt.

### Which saves more money, snowball or avalanche?

Avalanche never costs more interest and usually saves some. In a four-debt example of ₹3.2 lakh it saved ₹1,289, with both methods finishing in 27 months.

### Why does snowball work for many people?

Clearing a whole debt early gives a visible win and removes a bill. That motivation helps people keep going, which is often what decides whether the debt actually gets paid.

### Should I keep paying the same total after one debt is cleared?

Yes. Move the freed-up minimum to the next debt on the list. The total monthly payment stays the same while each debt falls faster.

### Can paying only the minimum on a credit card keep me in debt forever?

It can. If the minimum is about equal to the monthly interest, the balance barely falls. On a ₹20,000 balance at 36 percent the monthly interest is ₹600.
