If you’re staring at multiple debts and don’t know where to start, the hardest part isn’t maths. It’s motivation.
Credit cards, overdrafts, personal loans, buy now pay later balances. When they stack up, it feels overwhelming.
The snowball method is designed to fix that.
Here’s how it works, whether it’s right for you, and how to use it properly in the UK.
What is the debt snowball method?
The snowball method is a way of paying off multiple debts by focusing on the smallest balance first, regardless of interest rate.
You:
- List your debts from smallest to largest
- Pay the minimum on all debts
- Put any extra money toward the smallest debt
- Once that’s cleared, move to the next smallest
- Repeat until everything is gone
As each debt disappears, the amount you can throw at the next one grows. Like a snowball rolling downhill.
Why the snowball method works psychologically
On paper, paying the highest interest rate first often saves more money. That’s called the avalanche method.
But money isn’t just maths. It’s behaviour.
The snowball method works because:
- You see quick wins
- You reduce the number of accounts faster
- You build confidence early
- You feel progress within months rather than years
If you’ve tried paying off debt before and given up, the issue usually isn’t intelligence. It’s momentum.
The snowball method creates that momentum.
An example of the snowball method
Imagine you have these debts:
- Store card: £125
- Credit card: £350
- Overdraft: £400
- Payday loan: £550
- Student loan: £11,000
If you were focusing on interest rates (the avalanche method), you’d start with the most expensive debt, which might be the student loan or the payday loan.
But it could take years before you feel any progress.
With the snowball method, you’d start with the £125 store card. You’d clear it quickly, feel a sense of achievement and then move on to the credit card.
Each debt cleared gives you motivation to keep going.
The psychology of debt
The snowball method plays to human behaviour as much as it does to numbers.
- Quick wins matter: Paying off a small debt fast feels like progress, which motivates you to stick with it.
- Habit reinforcement: Each cleared debt is positive reinforcement for your new habits of budgeting and cutting back.
- Confidence boost: Instead of being overwhelmed by a huge balance, you feel in control.
Dave Ramsey, who popularised the method, often says that success with money is 80% behaviour and 20% knowledge.
That rings true: If willpower is your weak spot, the snowball approach can help you keep going.
Step by step: How to use the snowball method in the UK
Step 1: List every debt
Include:
- Credit cards
- Overdrafts
- Personal loans
- Store cards
- Buy now pay later
- Catalogues
Write down:
- Balance
- Minimum payment
- Interest rate
Don’t skip anything. Clarity matters.
Step 2: Order debts from smallest to largest balance
Ignore interest rates for now. Focus only on balance size.
Example:
- Overdraft: £450
- Credit card: £1,200
- Personal loan: £4,500
Step 3: Pay minimums on everything
You must stay current on all accounts. Missing payments damages your credit score and adds fees.
Step 4: Throw every spare pound at the smallest debt
Cut subscriptions. Sell unused items. Take on overtime. Redirect that money to the smallest balance.
Step 5: Roll the payment into the next debt
Once the smallest is cleared, take the amount you were paying and add it to the next one.
That’s the snowball effect.
How the snowball method plays out
Let’s say you have:
- Credit card A: £800 minimum £40
- Credit card B: £2,000 minimum £75
- Loan: £5,000 minimum £150
You have £300 per month available.
You pay:
- £40 to card A
- £75 to card B
- £150 to the loan
- That totals £265
You have £35 extra. You add that to card A, paying £75 per month.
- Card A clears first.
- Now you roll that £75 onto card B.
- Card B now receives £150 per month.
- When that clears, you roll everything onto the loan.
Your total monthly payment doesn’t increase. But the impact does.
Pros and cons of the snowball method
Pros
- Easy to understand and implement
- Builds momentum and motivation
- Reduces the number of debts quickly
- Improves confidence and money habits
Cons
- May cost more in interest compared with other methods
- Not the most mathematically efficient strategy
- Requires strict discipline to keep rolling payments forward
Snowball vs avalanche: which is best?
The avalanche method focuses on highest interest rate first. Mathematically, it usually saves more in interest.
The snowball method focuses on smallest balance first. Behaviourally, it often leads to higher completion rates.
If you:
- Struggle with motivation
- Feel overwhelmed
- Have abandoned repayment plans before
The snowball method is often more sustainable.
If you:
- Are highly disciplined
- Want to minimise interest
- Can stick to long-term plans
The avalanche method may suit you better.
Choose the method you’re most likely to complete.
When the snowball method might not be right
The snowball method isn’t ideal if:
- You’re facing court action
- You’re behind on priority debts
- You have very high interest payday loans
Priority debts in the UK include:
- Rent or mortgage arrears
- Council tax
- Energy arrears
- Court fines
- TV licence
These must be addressed first. The snowball method works best for non-priority unsecured debts.
UK-specific tips and resources
- Balance transfer cards: Consider moving credit card balances to a 0% card to buy breathing space (watch for fees and expiry dates).
- Debt charities: StepChange, Citizens Advice, National Debtline offer free, impartial guidance.
- Emergency fund: Build a £500–£1,000 buffer to stop new expenses from derailing your plan.
- Budget planners: MoneyHelper and MoneySavingExpert tools can help track spare cash for snowballing.
Final thoughts: Progress beats perfection
The biggest risk with debt isn’t paying too slowly. It’s giving up.
The snowball method focuses on momentum rather than optimisation. That makes it powerful.
If you’re serious about clearing debt, pick a strategy and commit to it for at least six months.
Watching your first balance hit zero changes how you feel about money. And once that happens, the next one feels possible.
Snowball method FAQs
1. Will the snowball method cost me more in interest compared with other methods?
Yes. Because it ignores interest rates, you might pay more overall. But many people find the motivational benefits outweigh the extra cost, especially if other methods haven’t worked for them.
2. Can I use the snowball method if I don’t have extra money beyond minimum payments?
Yes. It may take longer, but once you clear a small debt, the minimum you were paying on it can be added to the next debt, creating momentum over time.
3. How should I handle unexpected expenses while snowballing?
Build a small emergency fund first. Having £500–£1,000 set aside means a car repair or boiler breakdown won’t send you back into debt.
4. Is the snowball method better than the avalanche method for UK borrowers?
It depends on your personality. Snowball is better if you struggle with motivation. Avalanche is better if you’re disciplined and want to save the most interest. Some people blend the two.
5. Where can I get free debt help in the UK?
Charities like StepChange, National Debtline, and Citizens Advice provide free, confidential debt advice and can help you set up repayment plans.
