What this tool does
Calculate download time from technical measurements. Network rates are bits per second while file sizes are bytes. Estimate assumes steady throughput.
How to use the Download Time Calculator
- Enter or select file size (decimal gb).
- Enter or select connection rate (mbps).
- Enter or select usable throughput (%).
- Read the calculated result; change any measurement to compare alternatives.
Formula
seconds=size GB×8000/(Mbps×usable throughput/100)
- size
- File size (decimal GB)
- speed
- Connection rate (Mbps)
- efficiency
- Usable throughput (%)
Network rates are bits per second while file sizes are bytes. Estimate assumes steady throughput.
Worked example
For download time calculator, the following measurements illustrate the exact method: File size (decimal GB): 10; Connection rate (Mbps): 100; Usable throughput (%): 90.
Inputs
- File size (decimal GB)10
- Connection rate (Mbps)100
- Usable throughput (%)90
Result
- Estimated transfer seconds888.89
- Estimated minutes14.81
Results explained
- Estimated transfer seconds
- Estimated transfer seconds from the formula above. Network rates are bits per second while file sizes are bytes. Estimate assumes steady throughput.
- Estimated minutes
- Estimated minutes from the formula above. Network rates are bits per second while file sizes are bytes. Estimate assumes steady throughput.

Units appear in input and result labels. Keep lengths, pixel counts, bitrate and time units consistent.
Mathematical results follow the stated model; actual lenses, compression, viewing preferences and device specifications may differ.
