Tech calculator
Download Time Calculator
Find out how long a file, game, or update will take to download based on its size and your internet speed.
Estimated download time
—
Ideal estimate. Real-world download speeds may vary.
How does the Download Time Calculator work?
Enter the size of the file you want to download and your internet download speed. Calquo converts both values into compatible units and estimates how long the transfer would take under ideal conditions.
What's the difference between Mbps and MB/s?
Internet speeds are commonly advertised in megabits per second (Mbps), while file sizes and download programs often use megabytes (MB).
That means a 300 Mbps internet connection has a theoretical maximum transfer rate of:
Example: How long does a 100 GB game take to download?
Suppose you are downloading a 100 GB game with a 300 Mbps internet connection.
Why is my actual download slower?
The result is an ideal estimate. Your actual download may take longer because of Wi-Fi conditions, network congestion, server speed, other devices using your connection, protocol overhead, hardware limitations, or your internet provider.
Frequently asked questions
How long does a 100 GB download take at 100 Mbps?
Under ideal conditions, 100 Mbps equals 12.5 MB/s. A 100 GB file would therefore take about 2 hours and 13 minutes to download.
How long does a 100 GB download take at 1 Gbps?
Under ideal conditions, 1 Gbps equals 125 MB/s. A 100 GB file would take about 13 minutes and 20 seconds.
Is 1 Gbps the same as 1 GB/s?
No. Gbps means gigabits per second, while GB/s means gigabytes per second. Since there are eight bits in one byte, 1 Gbps equals a theoretical maximum of 125 MB/s, or 0.125 GB/s.
Can I use this calculator for game downloads?
Yes. You can use it for games, software, operating system updates, videos, backups, cloud files, and other downloads.
