How does a 0% purchase credit card work?

If you're looking to make an expensive purchase but aren't in a position to cover the cost upfront, a credit card that offers a 0% deal on spending can help you spread the cost over a longer period.

These cards won't charge any interest on purchases for an initial period of between three and 21 months. However, to really benefit you'll need to steadily repay the debt before the promotional period ends; otherwise, you'll be charged interest on the remaining balance at the card's standard APR - typically around 24%.

This guide reveals the best 0% purchase deals plus everything you need to know about how to use the cards effectively.

Is an interest-free purchase credit card better than a personal loan?

In some circumstances, a 0% credit card may be better suited to your needs than a personal loan.

With an interest-free credit card, you don't have to commit to anything higher than the minimum repayment each month. It's also a form of 'revolving credit', so what you pay back you can spend again. 

In contrast, when you take out a personal loan you will need to make fixed monthly repayments for as long as you've asked to borrow for and won't be able to use that money again.

The best 0% purchase credit cards offer up to 21 months interest-free but even with the cheapest loan, you will have to pay interest. The best personal loan deals  for £5,000 spread across three years is around 7.3% APR right now. 

The amount you can borrow may also differ. You can choose to borrow smaller amounts with a credit card - even if you are given a big limit. In contrast, the smallest amount you can get with a personal loan is £3,000 and the rates aren't as competitive compared to borrowing larger amounts.

The table sets out some of the main differences to consider.

Credit cardPersonal loan
You can borrow smaller amounts at competitive ratesThe smallest amount you can borrow is £3,000 and rates aren't as good compared to borrowing more
Repayments are flexibleRepayments are fixed
You can avoid paying interest for a number of months on a 0% purchase dealYou will have to pay interest on the money you borrow even on the cheapest personal loans
You get revolving credit so you can spend what you pay backYou can't spend any more than you originally borrow

How to use a 0% purchase credit card effectively

If you're planning to take out a 0% purchase credit card make sure you know the golden rules that will help you get the most out of the deal.

1. Only borrow what you need

With a 0% purchase credit card it's important to just borrow what you need and can afford to pay back.

So even if you get a credit card with a high limit of £10,000, you shouldn't max out your borrowing if you may be unable to clear the balance after the 0% period.

2. Make at least the minimum repayment each month

Even if you plan to delay repaying the bulk of what you borrow on a 0% purchase credit card you'll need to make at least the minimum repayment on time each month.

If you don't, you'll not only incur a late payment fee (typically around £12) but could lose the 0% deal altogether. To avoid getting caught out, set up a direct debit to cover this amount.

The minimum on a credit card is usually around 1% of the outstanding balance but can be more so double-check your card's terms and conditions.

If you can afford to pay back more than the minimum repayment you should.

3. Have a plan to repay the debt

The key to making the most of a 0% purchase credit card is to ensure you have no remaining debt when the interest-free period comes to an end.

A simple way to do this is to divide the total you've spent on your credit card by the number of months that your 0% deal lasts for and set up a direct debit to pay off that amount each month, in the same way you would pay off a loan.

Provided you don't make any more purchases, this will ensure you don't pay interest on what you've borrowed.

If you have some debt remaining after your card's promotional period ends, consider shifting this to a card that offers a 0% interest deal on balance transfers.

4. Don't withdraw cash on your card

You should avoid withdrawing cash using your 0% purchase credit card.

If you do you will be charged interest from the day you take the money out and usually at a much higher rate.

That's because your 0% deal is only for new purchases you make with the card online and in shops or restaurants - not for taking cash out of an ATM or for any other cash advance such as buying travel money.

Some providers also report when you make a cash withdrawal on your credit record, as it suggests you may be in financial difficulty.

How we analyse credit cards

Sam Wilson, credit card expert

Sam Wilson, credit card market analyst, says: 'At Which? we put credit card products and providers under the microscope to help you save time when shopping around for a new deal.

'We run a survey each year to gather the experiences of customers to help us find the best providers and we keep a close eye on the credit card market to determine which deals are the best in their category.'

Here's some more information about our research and the terms we use in this guide.

Customer score

Our provider customer scores are based on an online survey of 3,775 members of the public, conducted in October 2023. 

Customer scores are worked out using a combination of overall satisfaction and the likelihood of recommending the provider to a friend.

Which? Best Buys

To become a Which? Best Buy, a credit card must have been one of the top five cards in its category and must also satisfy specific criteria for the type of card such as the size of balance transfer fee or length of 0% period. A provider must have also achieved a provider score of over 65% in our latest credit card provider customer satisfaction survey. 

We also update our analysis regularly, which means we will withdraw Best Buys if providers make adverse changes to APRs, 0% periods or fees.

Which? Recommended Providers

We award Which? Recommended Providers to the lenders that meet our benchmarks on customer service and product offering.

To become a Which? Recommended Providers a lender must have:

  • a provider score of at least 75%
