One credit equals to one show-up to your visitor; Looping messages do not lead to further credit use until the visitor leaves the page or refresh.

Sample calculation 1
Each message group can contain up to 15 speech balloons. As each message group's maximum number of loop is 99 times:

15 x 99 = 1485 speech balloon displays = 1 Stream Credit

15.000 Stream Credits = 15.000 x 1485 = 22.275.000 speech baloon displays

This calculation is based on the maximum allowed numbers of 15 speech balloons per message group and 99 times of loop.

Sample calculation 2
If a user defines 5 speech balloons for a message group and allows for loop up to 7 times, then the Stream Credit calculation will be as follows:

5 x 7 = 35 speech balloon displays = 1 Stream Credit

15.000 Stream Credits = 15.000 x 35 = 525.000 speech baloon displays
