Game Download Time Calculator
Enter a game size in gigabytes and your measured download bandwidth in Mbps. Get an estimated download duration with optional overhead and a clear distinction between MB/s and Mbps.
Enter download speed in megabits per second (Mbps), not megabytes per second (MB/s). We use decimal gigabytes (1 GB = 8,000 Mb). Your real download may be slower due to servers, install/decompression, Wi-Fi or background traffic. No speed test is performed.
Mbps versus MB/s
Internet plans and speed tests commonly report megabits per second (Mbps); launchers sometimes display megabytes per second (MB/s). Eight bits equal one byte. A 100 Mbps connection can theoretically transfer about 12.5 MB/s before overhead.
Size, bandwidth and time
This calculator uses decimal gigabytes and estimated effective throughput. Example: 80 GB at 100 Mbps with zero overhead takes about 106.7 minutes, not 80 minutes. Actual downloads can take longer during decompression or installation.
Improve a slow download
Check the game launcher bandwidth limit, pause competing downloads, try a wired network and compare results across several intervals. A single speed test cannot guarantee a sustained rate from a specific game platform.
