How do I calculate how long it will take to upload a video or file?

Enter file size (in MB or GB) and your internet upload speed (in Mbps or KB/s) to calculate estimated transfer time in hours, minutes, and seconds.

Why is upload time slower than download time on home internet?

Most residential broadband connections are asymmetrical (e.g. 100 Mbps download but only 10 Mbps upload), making file uploads take up to 10x longer.

How long does it take to upload a 5GB video on a 20 Mbps connection?

A 5GB file (40,000 Megabits) on a 20 Mbps connection takes approximately 33 minutes and 20 seconds under optimal network conditions.

Does network overhead affect real-world transfer speed?

Yes. TCP/IP packet headers and Wi-Fi latency typically add 5% to 10% overhead, which the calculator factors into real-world estimates.

Can I calculate upload times for YouTube, Google Drive, and Dropbox?

Yes. Includes preset connection speed benchmarks (Fiber 1Gbps, 5G, 100Mbps, 25Mbps, 10Mbps, 4G LTE).

Can I calculate download times as well?

Yes. Toggle between upload and download estimation modes.

Mathematical Formula & Technical Methodology

\text{Transfer Time (s)} = \frac{\text{File Size (MB)} \times 8}{\text{Speed (Mbps)} \times \text{Efficiency (0.9)}}

Formula Variables Explained:
Accounts for TCP/IP protocol overhead and packet latency (~90% real-world efficiency).

Step-by-Step Worked Example

Uploading a 5GB video on a 25 Mbps broadband connection takes approximately 29 minutes.
