Hotspots and data
How much data does Zoom use on a Mac?
Zoom data use depends on what you do and the settings you choose. Check a real session before relying on an estimate.
When to check
- You want to use Zoom on a hotspot or limited connection.
- The data allowance is falling faster than expected.
How much data it uses
- What the provider says. Zoom recommends 600 kbit/s in each direction for high-quality one-to-one video, and 1.2 Mbit/s each way for 720p. If both 720p rates stayed constant for an hour, that would be about 1.08 GB combined. This is an illustration, not a measured or guaranteed hourly rate.
- Higher-quality and group calls. For 1080p Zoom recommends 3.8 Mbps up and 3.0 Mbps down. For group 720p it recommends 2.6 Mbps up and 1.8 Mbps down. The actual rates can differ.
- Why your total differs. Zoom adapts bandwidth to the network. Call layout, video quality, screen sharing and meeting conditions change use.
Measure a session
Open Activity Monitor, choose Network, and find the process for Zoom or its browser.
Note Sent Bytes and Rcvd Bytes before and after a session. Add their changes for a rough total.
Activity Monitor counts processes, not individual browser tabs. Other activity in the same browser affects the result.
A process restart resets its counters. A service can also use helper processes that need separate checks.
Reduce data use
In Zoom video settings, turn off HD when you do not need it. Zoom says HD uses more bandwidth.
Use a short test on the same connection to compare before and after.

Questions
Is there a fixed Zoom data cost per hour?
No. Settings and activity change the amount. Provider figures are estimates or rates, not your carrier bill.
Does a Mac show all hotspot traffic?
No. Other devices and the phone can also use the allowance. Compare with the carrier total.
