Your plan: Telus Share Plus 55
Data add on: $30(1GB + 1GB)
Close date of your bill cycle: 25
Activation Date: December 31, 2013
Step 1: $55(plan) + $30(add-on) = $85
Step 2: $85/30(days in 1 bill cycle) = $2.83
Step 3: $2.83 * 25(days remaining before the close date of bill cycle) = $70.83(Partial Charge from 12/31/13 - 01/25/14)
Step 4: $70.83 + $85(Whole month of service from 01/26/14 - 02/25/14) = $155.83
**Note: If you would like to calculate the partials for the plan or the add on/s only, just follow the same steps but make sure to start with Step 2. By the way, correct me if I'm wrong with the calculations I would greatly appreciate it. XD
first bill is composed of partial charge and one full month charge. when you first up your account, you were given your own billing cycle which date is nomally different on the date you started your servcie. for example: you started your service june 1 but your billing cycle close date is june 10.
partial charges are the usage from june 1-10 + the one full month charge considered as month in advance. this kind of biling happens everytime you make some changes on plan or features ( data add-on for example)
if your plan is $55 your charge will be like this: $55 devided by 30 days multiplied by 9 days (1-10) = 416.50 + $55 month in advance.
computaion is same with feature.
