How is interest charged on my Barclaycard account?
If full payment is not received, interest is charged based on an Average Daily Balance on the account. This is calculated by adding up the outstanding balance on your account each day and dividing by the number of days in the month. The sooner you make a payment to your account, the lower your Average Daily Balance will be and the less interest you will pay.
For details of interest rates relating to your account, please refer to your Terms and Conditions.
