How long will that game, app or movie take to download? Enter the file size and your internet speed to get a realistic download time, or find the speed you need to finish by a certain time.
How to use the download time calculator
- Pick an example or type the file size shown in the store (MB, GB or TB).
- Enter your internet plan speed. Most providers quote Mbps; Steam and browsers show MB/s.
- Choose how good your connection is: real downloads rarely hit 100% of your plan speed.
- Switch to “What speed do I need?” to find the plan speed for a deadline.
Mbps vs MB/s: why downloads feel slow
Internet speeds are measured in megabits per second (Mbps), while file sizes use megabytes (MB). One byte is eight bits, so a 100 Mbps plan can download at most 12.5 MB per second. Wi-Fi, busy servers and other devices on your network usually lower that further.
Frequently asked questions
How long does it take to download 100 GB?
On a 100 Mbps connection at typical real-world speed, about 2 hours 37 minutes. On 1 Gbps it takes around 16 minutes.
Why is my download slower than my internet plan?
Wi-Fi distance and interference, server limits, other people streaming on your network and the difference between Mbps and MB/s all play a part. A wired Ethernet connection is usually fastest.
How can I download games faster?
Use a wired connection, pause other downloads and streams, download at night when networks are quieter, and in launchers like Steam choose a nearby download region.
