Self-Hosted Stream Egress Calculator
For self-hosted RTMP/HLS: estimate the total egress bandwidth and monthly data your server needs for a given bitrate and concurrent-viewer count.
Self-hosting a stream means you pay for every viewer's download. 200 viewers at 4,500 kbit/s is ~0.9 Gbit/s of peak egress and, over 40 hours a month, ~16 TB of data — which is exactly why creators use a CDN or platform instead of their own server past a handful of viewers. This sizes the bill before you commit.
