Monthly Visitors Bandwidth Calculator

Work out how many visitors a bandwidth allowance supports.

About Monthly Visitors Bandwidth Calculator

Dividing the allowance by effective page weight gives the traffic a plan supports. Reducing page weight increases capacity proportionally, which is often cheaper than upgrading hosting. Halving page weight doubles the traffic a fixed allowance supports, which is the most direct link between performance work and hosting cost.

Formula
