This is a likely scenario when you activate a Base Pack or a Value Pack for the first time, it might not be the 1st of the month. In such a scenario the billing for the first month will be done on a pro-rata basis for remaining days in the month. The illustration below should help you understand how it is calculated:


Activation Date Base Pack / Value Pack Subscription Amount Billing Date Validity period No. of days left in the month * Billing amount
20/09/2016 Infinite Futures Plan 799 1st of every month 30 days 11 293
20/09/2016 Infinite Options Plan 99 1st of every month 30 days 11 36
10/09/2016 Call N Trade Pack 500 1st & 16th of every month 15 days 6 200
25/09/2016 Call N Trade Pack 500 1st & 16th of every month 15 days 6 200

* Pro-rata billing is calculated as (Subscription Amount / Validity Period * No. of days left in the month).

The billing happens on the 1st of every from the second month and in case of Call N Trade Pack it happens on 1st and 16th of every month.
