Networking & IT Infrastructure
Download Time Calculator — File Size vs Connection Speed
Time (s) = (file MB × 8) ÷ Mbps; accounts for megabit vs megabyte conversion.
Convert file size and link speed into estimated transfer time. Planning estimates only — verify with production tools and vendor pricing where applicable.

How this calculator works
Convert file size and link speed into estimated transfer time. Planning estimates only — verify with production tools and vendor pricing where applicable. Time (s) = (file MB × 8) ÷ Mbps; accounts for megabit vs megabyte conversion. Example: 5 GB file at 100 Mbps → ~6.8 minutes.
Time (s) = (file MB × 8) ÷ Mbps; accounts for megabit vs megabyte conversion.
Example: 5 GB file at 100 Mbps → ~6.8 minutes.
When to use this Bandwidth & Download Time
Common use cases
- Convert file size and link speed into estimated transfer time.
- Sanity-check with this case: 5 GB file at 100 Mbps → ~6.8 minutes.
- The relationship is: Time (s) = (file MB × 8) ÷ Mbps; accounts for megabit vs megabyte conversion.
Localized examples
- Networking & IT Infrastructure: the example on this page uses the same formula as the widget.
What you get
- Fields: File size (MB), Connection speed (Mbps), Protocol overhead (%)
- Time (s) = (file MB × 8) ÷ Mbps; accounts for megabit vs megabyte conversion.
- Example on the page: 5 GB file at 100 Mbps → ~6.8 minutes.
How to Calculate Bandwidth & Download Time Step-by-Step
- 1Enter File size (MB), Connection speed (Mbps), Protocol overhead (%). Use the values you have, not a catalog average, unless that is all you know.
- 2Time (s) = (file MB × 8) ÷ Mbps; accounts for megabit vs megabyte conversion.
- 3Worked case: 5 GB file at 100 Mbps → ~6.8 minutes.
- 4Compare the result to last month’s invoice or a vendor calculator before you commit capacity.
Governing formula
Time (s) = (file MB × 8) ÷ Mbps; accounts for megabit vs megabyte conversion.
5 GB file at 100 Mbps → ~6.8 minutes.
Example: set File size (MB) = 5,000, Connection speed (Mbps) = 100, Protocol overhead (%) = 10, then read the result.
Variable definitions

Very usable on mobile. Would love a save/export option later, but the math feels solid.
