Often customers are not sure how to estimate their bandwidth usage and just ask us to increase their bandwidth. Our practice at A B Host when we receive a non specific request to change bandwidth is to estimate your current daily bandwidth usage and multiply by 31 days. Then we add a 15% cushion and round up to next tier. If your bandwidth usage varies greatly by season or promotions, you may wish to give us more specific instructions.
Bandwidth is charged on a calendar month basis. You may check your current bandwidth usage in your cPanel or the details section of my services in your client area.
