How this calculator works
This unicast estimate assumes every viewer receives a full stream for the entire duration. Include audio in the stream bitrate. Caching, adaptive quality, viewer turnover and protocol overhead can change actual server demand.
The formula
Outbound Mbps = bitrate × viewers
GB = Mbps × 1,000,000 × seconds / 8 / 1,000,000,000A quick example
100 viewers at 5 Mbps each require 500 Mbps outbound bandwidth and transfer about 225 GB in one hour.
How to use this calculator
- Enter the labeled values, using a decimal point for fractions.
- Check the units and assumptions.
- Calculate, review the result and copy it if needed.
