Christmas is coming, and that means spending is inevitable. You're going to buy presents, food, decorations, and probably a few things you didn't plan on. But here's the thing: that spending doesn't have to be a drain on your finances.
If you've heard of stoozing but never quite got around to trying it, December is actually the perfect time to start. There's a neat bit of financial chemistry you can use right now — a combination of best 0% cards offers, holiday spending that's already happening, and the time value of money that means every pound you earn counts more when you're short on cash in January.
This guide is about making that work for you before the festive period gets into full swing.
What is stoozing, and why December?
Let's start with the basics. Stoozing is using a 0% credit card to earn interest on money you'd spend anyway. You spend on the card, move the money you would have spent into a savings account, and let the interest compound while the card charges nothing.
Most people think of stoozing as a spring or summer activity — something clever you do when the weather's nice and you've got time to plan. But December is actually where it gets interesting.
Why? Three reasons:
First, your spending is genuinely happening. You're not inventing reasons to spend; Christmas demands it. That means stoozing doesn't require you to artificially create expenditure just to hit a card's minimum spending.
Second, January is brutal for most people's finances. If you can turn your December spending into January savings, you've solved a real problem. Stoozing essentially lets you borrow the interest from your bank to offset the New Year cash crunch.
Third, there's still time. If you apply for a 0% card now — in late November — you'll get the card in time, spend through December, and have months of 0% interest stretching into early 2021 while you pay it off at your own pace.
The pre-Christmas stoozing playbook
Here's how to do this properly, step by step.
Step 1: Get the card approval sorted now
The fastest 0% cards right now are offering competitive rates, but the key is applying today, not on December 1st when everyone's thinking about it. You want the card in your hand with a week to go before the gift-buying season peaks.
There are several strong options available right now. Virgin Money is offering 0% for extended periods on balance transfers, and there are balance transfer cards from other lenders that'll give you 16+ months depending on your credit profile. Check the latest offers available to see what's live right now, and use our eligibility checker to see what you're likely to qualify for without impacting your credit score.
The best 0% cards right now can give you anywhere from 12 to 21 months of interest-free spending, which is more than enough to earn meaningful interest and pay the card off gradually in 2021.
Step 2: Calculate your realistic December spending
Don't guess. Get specific. Write down:
- Gifts (be honest about the total)
- Decorations
- Food and drink
- Petrol to visit family
- Christmas cards, wrapping, cards
- Any annual subscriptions renewing in December
- Anything else you'd normally pay for anyway
Most households are looking at £800–£1500 in December spending if you've got a family, or £300–£600 if it's just you. That's the pool of money you're working with.
Step 3: Move your real money to a savings account
Here's the crucial bit: when you spend £500 on the credit card, you need to have £500 sitting in a savings account somewhere. The money has to exist — you're not borrowing to create a balance. You're using the 0% interest-free period as a way to earn interest on your own money.
This sounds backwards, but it works because savings accounts are paying interest (even in late 2020, when rates are low). You put £500 in an easy-access account earning, say, 0.5% AER. That's £2.50 on £500 over a year. Boring, right? But you've also got the credit card statement of £500 that you'll pay off in January, February, or March when you're ready.
The interest you earn is free money that your bank is giving you for the privilege of holding your deposit.
Step 4: Choose where that money lives
The math works best if your savings account is paying meaningful interest. Right now, most easy-access accounts are around 0.5–0.75% AER. If you've got a larger amount to park, you might find notice accounts or fixed-rate bonds paying slightly more.
Put the money somewhere accessible so you can pay the credit card bill without scrambling. The last thing you want is to miss a payment date and lose the 0% rate.
Step 5: Pay off the card strategically in 2021
You don't need to pay the card the moment you get the statement. That's the beauty of the 0% period — you've got months.
The smart move is to:
- Make the minimum payment each month (usually 1–2% of the balance)
- Move the rest of the money from your savings account to the card as you go
- Pocket the interest your savings account earned
Let's work through a real example. You spend £1000 on the card in December. You move £1000 to a savings account at 0.5% AER.
- January statement: pay the minimum (say, £20). Move £980 to the card. Savings account now has interest earned (roughly £4 for December).
- February statement: pay £200 from your savings. Pocket the accumulated interest.
- March: pay another chunk. Interest keeps accumulating.
- April and beyond: finish paying off the balance.
It's not a fortune — we're talking tens of pounds, not hundreds — but it's genuine money you've earned from something you would have bought anyway.
Real offers you can use right now
As of late November 2020, there are several strong bank switch bonuses available that can complement your stoozing strategy. Whilst these aren't directly 0% cards, combining a switch bonus with stoozing gives you an extra kick:
- Nationwide: Currently offering up to £1500 switch bonus through BCWYC
- Virgin Money: £1000 switch bonus available
- First Direct: £250 bonus for switchers
- RBS and NatWest: £175 each
If you're planning a bank switch anyway (and most people switching get a bonus), you could do it in early December, get the bonus in early January, and treat that bonus as bonus interest on top of your stoozing.
The strategy: Switch bank in early December → Use the new account for your 0% spending → Get the bonus in January → Use bonus money to pay down the 0% card faster.
Common pitfalls to avoid
Don't spend beyond what you have
The entire stoozing game collapses if you spend £2000 on the card but only have £1500 in savings to cover it. The unused £500 goes on 0% for a year, but when the 0% expires, it suddenly costs you 18–22% interest. You've lost the game.
Only stooge with money that exists.
Don't miss a payment
One missed payment, and your 0% rate disappears. The card issuer will enforce the standard APR (usually 15–22%), and you're paying interest on the full balance. Mark your calendar, set phone reminders, and treat the card like you're paying a bill — because you are.
Don't max out the card
If your 0% card has a £3000 limit and you spend £3000, you've got no flexibility for emergencies. Keep 20–30% of the limit untouched.
Don't confuse stoozing with overspending
Stoozing makes December spending slightly more profitable, but it doesn't make bad spending good. If you're buying things you don't need just to "make stoozing work," you've missed the point. The goal is to earn interest on spending that's already happening.
Is stoozing worth it?
On £1000 of stoozing across a year, you're looking at roughly £4–5 in interest, plus any bonus money from switching. That's not going to change your life, but it's also genuine money that comes from being strategic about how you handle credit.
If you're someone who's considering a 0% card anyway (because you want a new card, or you're thinking about switching banks), then stoozing adds a real advantage to the decision. It's not the reason to do it, but it's a bonus when you do.
The real value is in the habit: getting comfortable with credit cards as a tool rather than a trap, understanding how to use bank bonuses, and developing a system for your money that works with your spending patterns rather than against them.

Common Questions
Can I stooge if I'm currently in my cooling-off checker period from a previous bank switch?
Yes, absolutely. The cooling-off period only affects your old bank's timeline; it doesn't stop you opening a new 0% credit card. You can be in a cooling-off period and still apply for a card. Just remember that credit applications will show on your file, though they're usually treated gently by lenders when you're clearly doing legitimate switching and financial planning.
What happens if interest rates change between now and January?
They won't affect your card's 0% rate — that's fixed for the duration of your offer. It might affect the savings account interest, which could drop or rise slightly. This is why you want to move money into savings now rather than waiting; locking in the current rate means less downside if rates fall further.
Do I need to use the card regularly to keep the 0% rate?
No. Once you've got the 0% approval, the rate is locked in. You can spend once in December and not use the card again, and the 0% still applies to that balance. Some cards have minimum spending requirements for bonuses, but the 0% rate itself doesn't require ongoing activity.
Can I pay the card off early without penalties?
Yes. 0% cards are usually completely flexible on repayment — there's no penalty for paying early, and no benefit for paying late (beyond the standard interest). Pay it off whenever you want; the 0% applies until you've cleared the balance or the interest-free period expires, whichever comes first.
How much interest will I actually earn?
That depends on the amount, the best savings rates, and how long you hold the money. £1000 in a savings account at 0.5% AER earns roughly £5 over a year. £2000 earns £10. It's not huge, but it's genuine profit from spending you'd do anyway, with no risk to you.
