To calculate your required network bandwidth, take into consideration the number of concurrent WiFi-enalble devices connected to your network and the internet apps WiFi users are using. Then, multiply this value by a certain amount of Kbps, as follows:
Number of concurrent devices (light usage) x 500 Kbps
Number of concurrent devices (medium usage) x 900 Kbps
Number of concurrent devices (heavy usage) x 2000 Kbps
You need to take into consideration the resources that your website uses, the average hits that it has, sometimes there are many users browsing the website at the same time etc. You can check the statistics of the previous month through your control panel and accordingly upgrade or downgrade the bandwidth that you will require accordingly.
Its really hard to predict the bandwidth which will be consumed by a website. It depends upon the below factors :-
1) Content of the website.
2) Concurrent users on the website.
3) Activity of each user and time for which he stays on the website.
4) Monthly users/traffic/hits expected.
