Download Time Calculator
Enter a file size and your download speed to estimate how long the download will take.
Estimated download time13m 20s
Theoretical file rate12.5 MB/s
Data10 GB
This is an ideal line-rate estimate. Wi-Fi, protocol overhead, storage, congestion and server limits can make the real transfer slower.
Download speed vs file speed
Internet plans are usually measured in megabits per second (Mbps), while download applications often display megabytes per second (MB/s). Because one byte is eight bits, 100 Mbps equals a theoretical 12.5 MB/s.
Why downloads can take longer
Your connection may share capacity with other traffic, and Wi-Fi, remote servers, storage and protocol overhead can reduce sustained throughput.
