Have you ever wondered what kind of network capacity would be required in order to stream a high-quality 1-hour event to 5 million users or how much it would cost? Or, the lowest amount you can charge users for your video content while staying profitable?

This free application offers handy calculations for streaming media professionals, CDN account managers, network engineers and content owners that are using a CDN or are in the process of selecting one.

Use Stream Calc to perform CDN capacity planning for live events (“size of the pipe”, or peak throughput in Gigabytes per second), estimate monthly data transfer (in Gigabytes or Terabytes), or figure out monthly hosting costs based on traffic.
