Bandwidth = [Total of Estimated Page Views (in 30 days) x Average Page Size + Total number of downloads (in 30days) x Average File Size] x Safety FactorThe value of safety factor depends on how ‘safe’ you want your website to be from sudden traffics spikes. A safety factor of 2 to 2.5 should be sufficient. The higher the safety factor, the more equipped your website is to survive in sudden traffics surge.
