Zoom Bandwidth and Data Use Calculator

This post explains how much data and bandwidth is required by Zoom.

Enter

  • Time spent in meeting (in minutes and seconds)
  • Meeting type (Voice or Video [High Quality, 720p or 1080p])
  • Number of users
  • Number of calls

The tool will provide

  • Bandwidth
  • Total data consumption

Example Calculations

  • A one minute Zoom voice meeting with a single user consumes 1.5 Megabytes.
  • A one minute Zoom video meeting with a single user consumes 15 MB to 57 MB depending on video quality.

A Zoom video meeting therefore consumes between 10 and 40 times the amount of data relative to a voice meeting. Something to remember if you’re traveling and using your cellular connection with limits on the amount of data used every month.

  • A one hour, single user Zoom video call consumes between 900 MB and 3.4 GB. We can see how this number can add up pretty quickly across even a small organization.

The calculator also allows you to plan your network bandwidth requirements. For instance, with 10 users the total bandwidth consumed is 38 Mbps at the highest quality setting.

Background

Zoom bandwidth consumption depends on whether it is a voice or video meeting and the app settings. We have used Zoom’s recommendation for the best performance settings. Compare requirements for other applications using the table provided here.

What is the Minimum Bandwidth required by Zoom?

Zoom supports three distinct performance levels: high quality video, 720p and 1080p. The minimum requirements are those consistent with high quality video shown in the table below.
