Streaming Bandwidth Calculator

Calculate the bandwidth and monthly data a set of concurrent video streams needs at a given quality level.

About Streaming Bandwidth Calculator

Concurrent sessions multiplied by per-session bitrate gives the aggregate demand; the overhead factor covers packet headers and retransmissions. Dividing by 8 converts bits per second into bytes to get the data volume. Sizing a link on average usage guarantees congestion at peak, and monthly data volume is what actually triggers a cap or an overage charge on a streaming service.

Formula

Streaming Bandwidth

Bandwidth (Mbps) = Concurrent streams × Bitrate per stream × (1 + overhead)

Concurrent sessions
Bitrate per stream
Sustained bitrate of one session

Worked example

Assumptions and limits

  • The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to 4 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

How is Streaming Bandwidth calculated?

Bandwidth (Mbps) = Concurrent streams × Bitrate per stream × (1 + overhead) Concurrent sessions multiplied by per-session bitrate gives the aggregate demand; the overhead factor covers packet headers and retransmissions. Dividing by 8 converts bits per second into bytes to get the data volume.

Why does Streaming Bandwidth matter?

Sizing a link on average usage guarantees congestion at peak, and monthly data volume is what actually triggers a cap or an overage charge on a streaming service.

What values do I need to enter?

This calculator takes 4 inputs: Concurrent streams, Bitrate per stream, Protocol overhead, Hours of use per day. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
