§01 ABOUT THIS TOOL
Overview
Hosting plans quote transfer in “GB per month” while network links are sized in Mbps — two units for the same thing. This calculator converts a transfer volume over a period into the sustained bit rate it implies, so you can sanity-check whether a hosting quota, a VPS port, or an office uplink matches your expected traffic.
How to use
- Enter the volume in the Data transferred field and pick its unit (
MB,GB,TB,PB). - Choose the period from the per dropdown (
second,minute,hour,day,month). - Read Sustained bandwidth — the required constant rate, auto-scaled from bps up to Tbps.

Notes
Units are decimal (1 GB = 10⁹ bytes) and a month is fixed at 30 days, matching how most providers bill. The figure is a pure average: it ignores protocol overhead, retransmissions, and daily peaks, so treat it as a lower bound when provisioning capacity.
FAQ
Are my numbers sent to a server?
No. The calculation is simple arithmetic performed entirely in your browser. Nothing is transmitted or stored.
How is the bandwidth calculated?
The data volume is converted to bits (decimal units: 1 GB = 10⁹ bytes, times 8) and divided by the period in seconds, with a month counted as 30 days (2,592,000 seconds). The result is the constant rate that would move that volume in that time.
Why does my server need more bandwidth than this number?
The result is an average. Real traffic is bursty — peak hours can run several times the mean — so capacity planning should apply a peak-to-average multiplier on top of this baseline, often 2x to 5x for typical websites.
