Streaming Bandwidth Calculator
Estimate aggregate network capacity for simultaneous streams using per-stream bitrate, protocol overhead and additional headroom. It is an early planning figure for a stated traffic scenario.
How to use this calculator
- Enter concurrent streams, bitrate per stream, protocol overhead percentage and additional capacity headroom.
- Check the labels and units before applying the result to a real task.
- Change one input at a time when comparing scenarios.
Formula and method
Required capacity = concurrent streams × bitrate × (1 + overhead%) × (1 + headroom%)
- Required capacity = concurrent streams × bitrate × (1 + overhead%) × (1 + headroom%)
- The estimate does not model caching, adaptive bitrate, traffic bursts, retransmissions, peering, redundancy or service-level requirements.
Worked examples
Worked example
One hundred concurrent 5 Mbps streams, 5% protocol overhead and 25% headroom.
Base traffic is 500 Mbps; with both factors the planned capacity is about 656.25 Mbps.

Frequently asked questions
Why add capacity headroom?
Headroom leaves room for variability and unexpected peaks rather than planning exactly at average payload demand.
Does every user stream the same bitrate?
Real services may switch among multiple bitrates. Use a representative or conservative per-stream value for the scenario you intend to estimate.
Is this a complete network design?
No. It is a throughput calculation only and does not evaluate latency, packet loss, architecture, redundancy or provider capacity.
