How the Bandwidth Calculator works.
bandwidth (Mbps) = file bytes × 8 ÷ seconds ÷ 1,000,000File size is converted to bytes; time is elapsed seconds; the output is decimal megabits per second.
Worked example for the Bandwidth Calculator.
A 1 GB decimal file transferred in 100 seconds requires 80 megabits per second because 1 GB is 8,000 megabits.
How to read this result.
The result is the ideal average link rate needed to move the entered payload within the entered time.
How this tool gets the answer
bandwidth (Mbps) = file bytes × 8 ÷ seconds ÷ 1,000,000. File size is converted to bytes; time is elapsed seconds; the output is decimal megabits per second. The result is the ideal average link rate needed to move the entered payload within the entered time.
A useful example
A 1 GB decimal file transferred in 100 seconds requires 80 megabits per second because 1 GB is 8,000 megabits. A quick way to verify the calculation is: Convert the file size to bytes, multiply by eight for bits, divide by seconds, then divide by one million for Mbps.
What the result tells you
The result is the ideal average link rate needed to move the entered payload within the entered time. Decimal MB and GB use powers of 1,000; binary MiB and GiB use powers of 1,024. Network rates are conventionally stated in bits per second.
Where the answer can go wrong
Transfer time must be greater than zero, and protocol overhead, retransmission, encryption, and competing traffic are not part of the payload calculation. A real connection should be provisioned above the ideal rate because advertised throughput and application payload throughput are rarely identical.
Privacy and practical use
The calculation runs locally in your browser and FigureNest does not send the entered values to a calculation service. Keep the source value and its unit with any result you save so you can reproduce the calculation later.

Reference guidance and methodology.
Bandwidth Calculator questions.
What does the Bandwidth Calculator do?
Calculate the ideal transfer rate required to move a file in a specified time.
How can I check the result?
Convert the file size to bytes, multiply by eight for bits, divide by seconds, then divide by one million for Mbps.
Which units and assumptions matter?
Decimal MB and GB use powers of 1,000; binary MiB and GiB use powers of 1,024. Network rates are conventionally stated in bits per second. A real connection should be provisioned above the ideal rate because advertised throughput and application payload throughput are rarely identical.
Are the entered values sent or stored?
No. The calculation runs locally in your browser and FigureNest does not send or store calculator inputs.
