Definition of 'Double-Cycle Billing'
A method used by creditors, usually credit card companies, to calculate the amount of interest charged for a given billing period.

Double-cycle billing can add a significant amount of interest charges to customers whose average balance varies greatly from month to month.
Also referred to as "two-cycle average daily balance".
