Core calculators
Calculate download time or required speed
Use the download time calculator when you know your internet speed, or use the download speed calculator when you know how quickly you want the file to finish.
Download Time Calculator
Enter a file size and download speed to calculate an estimated download time for a file, game, video, software package, or other transfer.
Calculate download timeDownload Speed Calculator
Enter a file size and target download time to calculate the theoretical internet speed required in Mbps and MB/s.
Calculate required speedDownload planning
Understand the relationship between file size, speed, and time
Larger files take longer to download at the same connection speed. Increasing your download speed reduces the time needed to transfer the same amount of data.

What download speed do you need?
The internet speed you need depends on the size of the files you download and how quickly you want them to finish. Smaller files can be downloaded comfortably at lower speeds, while large games, high-resolution videos, software, and backups can take much longer without a faster connection.
Internet plans commonly advertise download speeds in Mbps, or megabits per second. File sizes are commonly shown in MB and GB, which measure megabytes and gigabytes. Since one byte contains eight bits, Mbps and MB/s represent different measurements.
DownloadGauge provides two calculators so you can approach the same problem from either direction: calculate how long a file will take at a known speed, or calculate the speed required to finish a file within a target time.
