Here is a formula to calculate an estimate on the amount of bandwidth you will need:
Total Bandwidth/Month = Number of pages X .05 MB X Number of Visitors/Month
Note: This formula is based on the notion that each visitor will visit all the pages once. That is not likely to be the case, but the formula should work. Some visitors may view 1/3 of your site, while others may view your site twice. It all averages out.
