Video streaming bandwidth & CDN egress load calculator.

Estimate monthly data transfer in terabytes, calculate concurrent peak egress bandwidth in megabits per second, and evaluate infrastructure requirements before deploying video players to production.

Engineering Service Rates

We configure video players and CDN edge caching at $125–$200 USD per hour. For streaming platforms transferring over 50 TB monthly, our fixed $3,000 USD monthly retainer provides 20 hours of continuous manifest audits and egress monitoring.

Load Estimator

Adjust your playback metrics to model real-world CDN data transfer. The calculations follow standard streaming transfer formulas with a 25% concurrent burst headroom buffer.

Stated Calculation Formula:
Monthly Transfer (GB) = (Plays × Duration × 60 × Bitrate) / (8 × 1024 × 1024)
Monthly Transfer (TB) = Monthly Transfer (GB) / 1024
Peak Bandwidth (Mbps) = Concurrent Viewers × (Bitrate / 1000) × 1.25
Monthly Data Transfer (Primary Egress)
48.28 TB
Calculated total egress bandwidth across edge distribution nodes.

Includes 25% burst headroom buffer to prevent segment packet drops.

CDN Cache Performance vs. Direct Origin 98.4% Hit Ratio Target
Edge Cache In-Profile Segments (Target) 98.4%
Uncached Video Header Lookups (Origin Penalty) 1.6%
Unmanaged Embed Cache Thrash (Industry Baseline) 24.8%

Uncalibrated video players create origin traffic storms when thousands of clients request new HLS playlist variants concurrently. Our player configuration limits origin requests through strict byte-range caching rules.

Evaluation Criteria

What determines whether your streaming infrastructure requires hourly optimization or a dedicated engineering retainer.

Monthly Egress Bandwidth Recommended Engineering Engagement Estimated Monthly Retainer / Rate
Under 50 Terabytes Standard player configuration and buffer window calibration. $125–$200 / hr (Hourly)
50 to 250 Terabytes Continuous platform maintenance, manifest health audits, and edge caching rules. $3,000 / mo (20 hours)
Over 250 Terabytes Turnkey video project with multi-CDN automated failover routing and origin shielding. $20,000 USD (8–12 wks)
“If your stream fails on mobile WebKit under cellular packet loss, the issue is manifest segment sizing, not network bandwidth.”
