Video Streaming Bandwidth Calculator.
Estimate peak delivery bandwidth, monthly data and CDN cost for live or on-demand video from viewers and an adaptive bitrate ladder.
One high-quality stream when the platform transcodes; the sum of all levels when you transcode locally.
- Average bitrate per viewer
- 4,147 kbps
- Monthly data delivered
- 44.79 TB
- Upload needed at the encoder
- 9 Mbps 1.5 × the encoder output, a common safety margin
- Single-server 10 GbE capacity
- 1,929 viewers At 80 % of the port
- Live and on-demand video delivered from one origin rarely scales past a few thousand viewers; a CDN serves cached segments close to viewers.
- Bitrates are your encoding ladder; use the bitrates configured in your encoder or platform.
How to use Video Streaming Bandwidth Calculator
Enter peak viewers, the bitrate and viewer share of each quality level, hours per month and average audience. Add a CDN price to estimate cost.
How it works
Average bitrate is weighted by viewer share; peak bandwidth = peak viewers × average bitrate; monthly data = average viewers × bitrate × hours.
Example
1,000 viewers on a 1080p/720p/480p/360p ladder need about 4.2 Gbps at peak.
Questions about Video Streaming Bandwidth Calculator
Is Video Streaming Bandwidth Calculator free, and do I need an account?
Yes. This tool is free to use in your browser without an account. Processing takes place on your device.
What are the limits and what should I check?
Bitrates are your encoding settings; CDN prices are entered by you. Player buffering and retransmissions are covered only by the overhead percentage. Everything is calculated in your browser; nothing is sent or probed on the network. Review the result before using it in your work.
