Understand the result
A reproducible bandwidth estimate
10,000 plays × 5 minutes × 60 × 3,000,000 bits/s ÷ 8 ÷ 1,000,000,000 = 1,125 decimal GB
This is a modeled transfer scenario. It excludes protocol overhead and assumes the stated average bitrate throughout the watched duration. A 10% margin makes it 1,237.5 GB; it does not turn the estimate into measured traffic.
Use observed inputs when available
Use watched duration and average delivered bitrate rather than the uploaded source bitrate. Adaptive playback varies quality. Keep storage minutes separate from delivered minutes, and compare features and overage terms as well as the calculated amount.
What this tool can and cannot tell you
Use average delivered bitrate, not source-file bitrate. Adaptive streaming changes quality across viewers. A capacity fit is not feature parity: verify DRM, access controls and overage terms. Prefetch and replay can increase the bill.
Common questions
Is GB the same as GiB?
No. This tool uses decimal gigabytes. Do not compare it to a binary-gigabyte limit without converting units.
Should I add all HLS renditions together?
Not for one viewer's playback estimate. Renditions represent different quality choices; model the actual mix or separate scenarios.
Does the cheapest capacity fit include every feature?
No. Check required features and accepted terms independently before selecting a hosting plan.
