Live Webcast Bandwidth, Concurrent Viewers & CDN Egress Calculator
Model peak bitrates, total petabyte network egress, concurrent viewer throughput, and CDN cloud bandwidth bills for live webinars, keynotes, and broadcasts.Documentation & FAQs ↓
Step-by-Step Instructions
4 Steps to CompletionEnter your expected peak concurrent viewers (CCU) and total event broadcast duration in hours and minutes.
Select your target video quality profile (e.g., 1080p Full HD at 6,000 kbps, or Adaptive Bitrate distribution).
Configure your cloud CDN egress cost per gigabyte (typically $0.02 to $0.08 per GB depending on contract volume).
View peak throughput requirements (in Gbps), total data transferred (in TB), and estimated CDN egress charges.
Practical Use Cases & Real-World Scenarios
Multi-Resolution Bitrate Ladder Matrix
Models encoding profiles from 720p (2.5 Mbps) and 1080p60 (6.0 Mbps) up to 4K UHD (18.0 Mbps) with companion audio bitrates.
Peak Concurrent Bandwidth Capacity
Calculates instantaneous network pipeline capacity required in Gbps or Tbps to ensure origin and edge CDN connections avoid buffering.
Total Network Egress Volume Estimator
Quantifies cumulative data consumption in gigabytes (GB) and terabytes (TB) across event durations and concurrent viewership curves.
Tiered Cloud CDN Billing Comparison
Projects cloud egress bills based on published enterprise bandwidth tiers from Cloudflare, AWS CloudFront, Fastly, and Akamai.
