You will benefit from an interest-free grace period as noted above on any new purchases appearing on your account statement for the first time if you pay off your balance in full by the payment due date.
To calculate interest charges on cash advances, we multiply the daily closing balance of your cash advances by the daily cash advance interest rate, which is equal to the annual cash advance interest rate divided by 365.
