American Express has launched an instalment option called Plan It for its credit card customers to offer a new way to spread the cost of purchases.
It will allow you to select certain purchases of more than £100 and choose to pay for them in three, six or 12-month instalments for a monthly fee instead of paying interest.
Here, Which? explains how the new feature works, if it’s worth using and how it compares with similar instalment initiatives from Barclaycard, Monzo, NatWest and Virgin Money.

How does Plan It work?
You can use the Plan It feature if you have one of the following cards:
Platinum Cashback Everyday Credit Card
Platinum Cashback Credit Card
American Express Preferred Rewards Gold Credit Card
British Airways American Express Credit Card
British Airways American Express Premium Plus Card
The Platinum Card
Nectar Credit Card
Marriott Bonvoy
American Express Card
Vitality American Express Credit Card
British Airways American Express Accelerating Business Card
Those with an eligible card can select a transaction, or an amount from their most recent statement and put it in an instalment plan. It must be more than £100.
The instalment plan options are three, six and 12 months.
You’ll be charged a fixed monthly fee for your instalment plan, but you won’t be charged interest on the balance in your plan.
Your monthly instalment amount will be part of your minimum payment due on your billing statement. The first instalment will appear on the first statement after you create a plan.
You’ll earn rewards on your purchase as usual.
You can have multiple instalment plans, but the amount you can have at once will depend on your card and credit limit.
Amex said the monthly fee charged will be comparable to the interest you would pay if you carried the balance without creating an instalment.
You can use its calculator to see how much it would cost, which assumes an interest rate of 30%. However, you may be charged less/more depending on your card's APR.
Your monthly instalment amount will include the monthly plan amount and the monthly fee.
Here’s how much it would cost to use Plan It versus having no instalment plan for £100 using all three plans.

As you can see from the tables, the amount of money you save is minimal when using the instalment plan.
But you may find it gives you more flexibility with how you manage your spending on a credit card. You can split purchases you know will take a while to pay off from your everyday spending and have different strategies for paying off each.

Amex is a Which? Recommended Provider and achieved a provider customer score of 79% – putting in second in our table behind Tesco Bank.It scored five stars for its mobile app and clarity of statement and four stars for its transparency of charges, application process and customer service.
It also has three cards tha have our Best Buy endorsement – the American Express Rewards Credit Card for airmiles, the American Express Platinum Cashback Credit Card and the American Express Platinum Everyday Credit card for cashback.
Several other providers offer the option to pay down your credit card bill with instalment plans.
Here's how the Plan It by American Express compares with similar schemes, ordered alphabetically.
Provider scheme
Minimum amount
Instalment term offered
How is monthly fee calculated?
American Express Plan It
£100
3, 6, 12 months
Equivalent to interest rate of card (fo example, 30% APR)
Barclaycard Instalment Plan
£100
3 to 24 months
Monthly fee 1% to 8%, subject to credit limit
Monzo Flex
£30
3, 6, 12 months
No fee if 3 month option selected, 29% APR for 6 or 12
NatWest credit card instalment plans
£50
3, 6, 12, 24 months
Less than the equivalent interest rate of the card, typically 11.9% rather than 18.9% APR
Virgin Money Slyce
£30
3, 6, 9, 12 months
No fee for 3 and 6 month plans. 9 month charged at 7.5%, 12 months charged at 10%
Monzo Flex and Virgin Money have the most competitive offer as you can get 0% interest on purchases with no monthly fee for at least three months (Virgin Money Slyce offers six months).
These options are similar to buy now, pay later schemes where you don't pay interest on purchases if you can pay back what you borrow withing a short period.
American Express said that using Plan It would provide ‘flexibility and control, taking the guesswork out of your payments’ allowing customers to have fees that are 'clearly outlined' at the start of their plan.
While this is true, we’re struggling to think of any more reasons to use this feature as you won’t save much in interest in the long run.
With reward credit cards, we recommend paying off the balance in full every month to avoid hefty interest charges that are common with these types of cards.
These cards won’t charge interest for a set period of time (typically between three and 21 months right now). However, if you don't manage to pay off the amount within this period, you'll be charged interest on the remaining balance at the card's standard APR – typically around 20%.
