The calculator uses the following formula's:

Traffic in megabytes per day =
VisitorsPerDay * PagesPerVisitor * PageSize / 1048576
Traffic in gigabytes per month =
VisitorsPerDay * PagesPerVisitor * PageSize * 30.41 / 1073741824
Traffic in megabytes per visitor =
PagesPerVisitor * PageSize / 1048576
Minimum bandwidth needed =
VisitorsPerDay * PagesPerVisitor * PageSize * 8 / (86400 * 1000)
Maximum bandwidth needed =
VisitorsPerDay * PagesPerVisitor * PageSize * 8 * 3 / (86400 * 1000)
Visitors per second =
VisitorsPerDay / 86400
Visitors per day =
(input field)
Visitors per month =
VisitorsPerDay * 30.41
Pages per second =
VisitorsPerDay * PagesPerVisitor / 86400
Pages per day =
VisitorsPerDay * PagesPerVisitor
Pages per month =
VisitorsPerDay * PagesPerVisitor * 30.41
Download time per page =
86400 / (VisitorsPerDay * PagesPerVisitor)
Simultaneous visitors =
VisitorsPerDay * PagesPerVisitor / 1440
