Why your Steam download takes longer
8 bits = 1 byte. A 100 Mbps connection can transfer at most about 12.5 MB/s before real-world overhead. Steam can display bytes per second or bits per second, so check the unit before comparing results.
Network congestion, Steam download region, other devices, server performance and installation or decompression can extend total time. The calculator estimates transfer time; it does not predict installation time or measure your network.

Common questions
How long is 100 GB at 100 Mbps?
Ideal transfer time: 2 hours 13 minutes 20 seconds. At an assumed 80% effective speed: 2 hours 46 minutes 40 seconds. Installation can take longer.
Why does Steam show 10 MB/s instead of 80 Mbps?
They measure the same data rate: 10 megabytes per second = 80 megabits per second. Check whether Steam is set to display download rates in bits or bytes.
Does 100 GB of disk space always mean a 100 GB download?
No. Installation size, patch size, compression and download size can differ. Use your launcher's current download estimate where available.
