Bandwidth vs Download/Upload Transfer Time Sizer
Calculate how long a file transfer will take given a connection's advertised bandwidth in bits per second.
Your inputs
Change any value to update the result instantly.
Estimated transfer time
1,000 seconds
Effective throughput
10 MB/s
Transfer time (minutes)
16.6667 min
Rated bandwidth
100 Mbps
ISPs advertise speeds in megabits (Mb) while file sizes are usually shown in megabytes (MB) — divide Mbps by 8 to get MB/s.
Formula and working
Time (s) = File size (bits) ÷ Bandwidth (bits/sec); File size (bytes) × 8 = bits
- 1
Collect the inputs
File size (GB) = 10; Connection speed (Mbps) = 100; Real-world efficiency factor = 80 %
- 2
Apply the formula
Time (s) = File size (bits) ÷ Bandwidth (bits/sec); File size (bytes) × 8 = bits
- 3
Result
Estimated transfer time = 1,000 seconds
