Debt Snowball vs Debt Avalanche: Which Works Best?
If you’re trying to pay off debt UK households commonly struggle with, choosing the right repayment strategy can make a huge difference. Two of the most popular methods are the debt snowball and the debt avalanche. Both work—but they work differently, and the best option depends on your personality, finances, and motivation.
What Is the Debt Snowball Method?
The debt snowball method focuses on paying off your smallest debt first, regardless of interest rate. You make minimum payments on all other debts and throw any extra money at the smallest balance.
Once that debt is cleared, you roll its payment into the next smallest debt—creating momentum, like a snowball rolling downhill.
Example:
- Credit Card A: £500 balance, 22% APR
- Credit Card B: £1,800 balance, 19% APR
- Credit Card C: £4,000 balance, 24% APR
You would pay off Credit Card A first, even though it doesn’t have the highest interest rate.
Pros of the Debt Snowball
- Quick wins keep motivation high
- Simpler and emotionally rewarding
- Great if you feel overwhelmed by multiple debts
Cons of the Debt Snowball
- You may pay more interest overall
- Not mathematically the fastest method
What Is the Debt Avalanche Method?
The debt avalanche method prioritises debts with the highest interest rate first, regardless of balance size. You still make minimum payments on all debts but direct extra money to the most expensive debt.
This approach is mathematically the most efficient way to pay off debt UK households owe on credit cards.
Using the same example:
- Credit Card C (24% APR) would be paid off first
Pros of the Debt Avalanche
- Saves the most money on interest
- Faster overall debt reduction
- Best for high-interest credit card debt
Cons of the Debt Avalanche
- Slower initial progress can feel discouraging
- Requires patience and discipline
Debt Snowball vs Debt Avalanche: Key Differences
| Feature | Debt Snowball | Debt Avalanche |
|---|---|---|
| Focus | Smallest balance first | Highest interest first |
| Motivation | Very high | Moderate |
| Interest saved | Lower | Highest |
| Best for | Behaviour change | Cost efficiency |
