WebRTC Video Costs: TURN, SFU & the Egress Bill Nobody Models
A 1:1 video call is cheap: peer-to-peer WebRTC, minimal server cost. A 50-person call is a different business: every participant uploads once and downloads 49 streams -- or your SFU (Selective Forwarding Unit) routes it all, and you pay egress per GB. At $0.09/GB (AWS), a 1-hour 50-person call at 1 Mbps per stream moves ~20GB = $1.80 in egress alone. Scale to 10,000 daily meeting-hours and egress is $18,000/month -- the line item that kills video startups.
The architecture decisions: P2P mesh (free servers, dies past 4-6 participants as each client uploads N-1 streams), SFU (server routes streams; scales to hundreds; you pay bandwidth + servers -- LiveKit, Daily, Twilio), MCU (server mixes into one stream; lowest client bandwidth, highest server CPU). TURN servers: needed when symmetric NATs block P2P (~15-25% of calls) -- coturn on a $20 VPS handles thousands of relayed minutes, but relayed traffic costs YOU egress both ways. Most teams under-provision TURN and get mysterious call failures on corporate networks.
Cost optimization levers: simulcast/SVC (send multiple quality layers once; SFU forwards appropriate layer -- saves 40-60% downstream bandwidth), audio-only fallback, pagination (show 9 videos, not 49 -- the streams you do not render you do not pay for), region placement (egress varies 2-3x by cloud region; serve users from nearest PoP), and managed vs self-hosted SFU (LiveKit Cloud ~$0.004/participant-minute vs self-hosted at ~$0.001 -- the crossover is around 2M minutes/month when your DevOps cost justifies itself). The calculator models participants, duration, architecture, and region into true per-minute costs.

Practical Worked Example — WebRTC LiveKit / Agora SFU & TURN Relay Cost Calculator
Benchmarking 10k daily meeting-hours with WebRTC LiveKit / Agora SFU & TURN Relay Cost Calculator
Sample Input: Monthly Video Call Hours: 25 k hours (Range: 1–1000 k hours) | Avg Participants per Room: 4 users (Range: 2–50 users) | Managed Rate per 1k Participant-Mins: 3.5 USD (Range: 0.4–12 USD)
Sample Output: Total Monthly Participant-Minutes: 6 M mins | Managed WebRTC Platform Bill: 21,000 USD/mo | Self-Hosted LiveKit + Egress Est: 2,145 USD/mo
Using the baseline configuration (Monthly Video Call Hours = 25 k hours, Avg Participants per Room = 4 users, Managed Rate per 1k Participant-Mins = 3.5 USD), WebRTC LiveKit / Agora SFU & TURN Relay Cost Calculator yields Total Monthly Participant-Minutes = 6 M mins and Managed WebRTC Platform Bill = 21,000 USD/mo. Scaling Monthly Video Call Hours to 37.5 k hours shifts Total Monthly Participant-Minutes to 9 M mins.
Platform Scenarios
- 10k daily meeting-hours: Self-hosted SFU + simulcast: ~$8k/mo egress+servers vs $25k+ managed.
- Telehealth 1:1s: P2P mostly, TURN fallback: pennies per call. Architecture matches the use case.
Technical Scope, Assumptions & Limitations of WebRTC LiveKit / Agora SFU & TURN Relay Cost Calculator
- Calibrated specifically for Monthly Video Call Hours values between 1 and 1000 k hours and Avg Participants per Room between 2 and 50 users; extreme outlier values outside these bounds may exhibit non-linear variance.
- Outputs generated for Cloud FinOps & GPU Infra (Total Monthly Participant-Minutes and Managed WebRTC Platform Bill) represent deterministic engineering/financial estimates and should be verified against your specific vendor contract or local jurisdiction rules.
- Because all calculations run statelessly in local browser RAM, closing the tab resets custom slider positions unless you export the CSV report first.

WebRTC Cost FAQs
What is a TURN server?
A relay for WebRTC traffic when direct P2P fails (symmetric NATs, firewalls) -- ~15-25% of calls. Cheap to run (coturn), but relayed bytes cost egress twice.
SFU or MCU?
SFU for most: scales well, moderate bandwidth. MCU when clients are weak (mixes to one stream) at higher server cost.
