The billing cycle is once per month. Memberships will be billed on or around the date of activation for the calendar month of the membership.  All memberships are from the 1st of the month until the last day of each month.  For example, if you start on the 15th of a month, you will be billed on the 15th of each subsequent month for your membership ranging from 1st-last day of that month.  Any membership that is canceled will prorated from the 1st until the effective date of cancellation (which is on average 72 hrs following the receipt of cancellation request).  Final month will be billed in its entirety and any prorated refund will be returned within 72 hours following account close out.
