Follow these steps to determine how the Monthly Recurring Charge (MRC) is determined for a plan change:

1. Divide the monthly service charge by the number of days in the billing period to get the daily service charge

(Note: There can be 28 to 31 days in a billing period depending on the calendar month. Usually the number of days in the billing period will equal the number of days in the month when the billing period begins. For example, billing periods beginning in March and ending in April will have 31 days because there are 31 days in March.)

2. Multiply the daily service charge by the number of days the plan was active to get the partial monthly service charge
3. Repeat step 2 for each plan to determine the total monthly service charges for the billing period
