Stream Upload Headroom Calculator

Check whether your internet upload speed can safely sustain a stream bitrate — with the safety margin live streaming needs.

Upload used by stream (%)
Headroom remaining (Mbit/s)

Streaming bitrate should use no more than about half your real upload speed — the rest absorbs bandwidth dips, other devices and protocol overhead. A 6.16 Mbit/s stream on a 10 Mbit/s upload uses 62%, which is risky; you want headroom so a momentary dip doesn't drop frames mid-stream. Test your real upload, not the plan's headline number.

Rule / Formula

upload used = total bitrate ÷ upload speed; keep streaming bitrate ≤ ~50% of measured upload
References: Live-streaming bandwidth headroom best practice
