How long that 120 GB install is really going to take.
100% assumes you get every bit of your advertised speed. Most connections sit around 80–90% once the download server, other devices and evening congestion take their share.

Enter the size of the download and the speed of your connection to get a realistic estimate. The common trap is that internet speeds are sold in megabits and file sizes are measured in megabytes — eight times larger — so a 50 Mbps connection downloads at roughly 6 MB per second, not 50.
The maths: time in seconds = (size in megabytes × 8) ÷ (speed in megabits per second), adjusted by the efficiency setting. Real downloads are usually slower than the ideal figure — the game's servers, other devices on your connection, evening congestion and the console or PC writing to disk all take a share.
The calculator assumes you get your full advertised speed with nothing else competing for it. In practice the download server has its own limits, other devices share your line, and connections slow down during busy evening hours. Setting efficiency to around 80% gives a more realistic estimate for most connections.
Mbps is megabits per second and is how internet speed is sold. MBps is megabytes per second and is how download progress is usually displayed. One byte is eight bits, so divide your Mbps figure by eight to get the download speed you will actually see.
At a full 50 Mbps, roughly four and a half hours. At 25 Mbps, about nine hours. At 100 Mbps, a little over two. Allow more if your connection does not sustain its full rated speed.
It can matter a great deal. A wired connection generally sustains a speed close to what your line can deliver, while Wi-Fi varies with distance, walls and interference. For a very large download, a cable is worth the inconvenience.
Because downloading and installing are two different jobs. Once the data is down, the console still has to unpack and write it, which is limited by storage speed rather than your connection.
