Bandwidth Calculator
Calculate exactly how long it will take to upload or download a file based on your internet connection speed.
How to use this tool
- Enter File Size: Input the size of the file you want to transfer (e.g., 10 GB for a movie, or 50 MB for a document).
- Select Speed: Enter your connection speed in Mbps (Megabits per second).
- Average US Speed: ~200 Mbps
- Fiber Optic: 1000 Mbps (1 Gbps)
- 4G LTE: ~40 Mbps
- 5G: ~150 Mbps+
Understanding bits vs Bytes
Internet speed is measured in bits (Megabits, Gbps), while file storage is measured in Bytes (Megabytes, Gigabytes).
- 1 Byte = 8 bits
- This is why a 1 Gigabit connection (1000 Mbps) only downloads at ~125 Megabytes per second (MB/s).
- Our calculator handles this conversion automatically.
[!TIP] Pro Tip: Real-world speeds are often 10-20% slower than advertised due to network overhead.
