What is a credit limit?
A credit limit is the maximum balance you can have on your Barclaycard at any time. To decide what your limit should be, we take a few things into account including how long you've been a customer, and how you’ve used credit cards in the past. You’ll see your limit on your monthly statements, and on the transactions page of the app.
Your 'available credit' is your credit limit minus the amount that’s outstanding on your card.
