Game Download Time Calculator
Big games can be 100 GB or more. Enter the download size and your connection speed to see how long you will wait, and how much faster a better connection would be.

How to use it
- Enter the download size from the game store page and choose GB or MB.
- Enter your internet speed. Providers use Mbps, while download managers often show MB/s.
- Read the estimated time. Lower the efficiency if your connection is often busy.
Mbps and MB/s are not the same
Internet plans are sold in megabits per second (Mbps). Game launchers usually show megabytes per second (MB/s). One byte is eight bits, so a 100 Mbps connection can at best download 12.5 MB/s. This tool converts both for you.
Why it is slower than the math
The theoretical time assumes the full line speed. In real life the store servers, Wi-Fi, other devices and your router all take a share, so the tool applies an efficiency of 90 percent by default. Using a cable instead of Wi-Fi and pausing other downloads brings you closer to the best case.
Frequently asked questions
How long does it take to download 100 GB?
At 100 Mbps it takes about two and a half hours, at 300 Mbps about 50 minutes and at 1 Gbps about 15 minutes in good conditions.
What is the difference between Mbps and MB/s?
Mbps is megabits per second and MB/s is megabytes per second. Divide Mbps by 8 to get MB/s.
Why is my download slower than my plan?
Wi-Fi quality, server load, other devices and the distance to the server all reduce the real speed. A wired connection helps.
Does an SSD change download time?
Not the download itself, but a slow drive can limit installation speed on very fast connections.
