Tech calculator
Bandwidth Calculator
Find the Mbps, Gbps, and megabytes per second needed for a transfer deadline.
Required bandwidth
100 Mbps
How the bandwidth calculator works
Calculate the network bandwidth required to transfer a file within a target time.
Moving 1 GB in 80 seconds requires 100 Mbps, or 12.5 MB/s, using decimal units.
Assumptions and limitations
Results describe payload throughput. Protocol overhead, congestion, Wi-Fi conditions, and server limits can make real transfers slower.
Inputs and results stay in your browser. Blank, invalid, or mathematically undefined inputs show a clean placeholder instead of a broken number.
Practical use
Use this tech calculator to explore scenarios quickly, then verify important decisions against the original source data or requirements.
Frequently asked questions
Does the bandwidth calculator send my data anywhere?
No. It runs client-side in your browser and makes no network requests.
Why is the result blank or shown as a dash?
One or more inputs are blank, outside the accepted range, or would make the calculation undefined. Check the labels and enter finite values.
Can I use decimal values?
Yes, where decimals are meaningful. Counts that represent whole items may require integers.
