How much data does Zoom use? Costs per hour in rand

If you tutor online, work remotely or go to interviews on Zoom, your calls can eat data faster than you expect.

This guide turns Zoom's own bandwidth numbers into data per hour, shows what an hour costs in rand on a real South African bundle, and lists the settings that save the most.

How Zoom's numbers work

Zoom publishes a recommended bandwidth for each kind of call: how fast your connection should be, in kilobits or megabits per second, for the call to run well.

To turn that into data per hour, multiply by 3,600 seconds and divide by 8 (there are 8 bits in a byte). We add the upload and the download together, because your bundle counts both.

Zoom also says it adjusts to your network, whether you're on mobile data, Wi-Fi or a wired line. So treat the numbers below as a guide for budgeting. Your phone's data usage screen shows what a real call used.

Zoom data use per hour

A few more of Zoom's numbers are worth knowing:

• Gallery view with 25 people on screen needs 2.0 Mbps just to receive the video. That's double the download speed Zoom recommends for a high-quality group call.
• Screen sharing with no video needs only 50 to 75 kbps, a small fraction of what video needs.

So the camera, HD and gallery view are what push your data up. Audio and a shared document use very little.

What an hour costs in rand

Here's an example using one real price. MTN's SuperFlex 10GB contract went up to R329 a month from 1 February 2026, according to MTN's price list. That works out to about R33 per GB.

At that price, an hour on Zoom costs about:

• R2.40 for audio only
• R18 for one-on-one video in high quality
• R24 for a group video call in high quality
• R36 for one-on-one video in 720p HD
• R65 for a group call in 720p HD

Prices differ a lot between networks, prepaid bundles and specials, so work it out with the price you pay. Our calculator does it for you.

A worked example: an online tutor

Say you tutor five one-hour lessons a week on one-on-one video in high quality.

• That's about 2.7 GB a week, or about 11.7 GB a month.
• At R32.90 a GB (R329 for 10GB), that's about R385 in data each month.
• The same lessons on audio only would use about 1.56 GB a month, or about R51.

That gap is why it pays to know when video really matters. Some lessons need it. Many don't need it the whole time.

Ways to use less data on Zoom

1. Switch your camera off when no one needs to see you. Zoom suggests this when your connection is slow, and audio uses far less data than video.
2. Turn off HD video. In the Zoom app's settings, open the video settings and switch HD video off. Zoom says HD uses more bandwidth.
3. Stop incoming video when you only need to hear people or see a shared screen. In a meeting, Zoom lets you stop all incoming video for your own view only. Others aren't affected.
4. Use speaker view in big meetings. Gallery view receives many video feeds at once.
5. Share a document or slides instead of playing a video over Zoom.
6. Pause big downloads, cloud backups and streaming on your phone and laptop during the call.

Why this matters for earning

Stats SA's General Household Survey 2025 found that 78.9% of households access the internet on mobile devices, while 20.6% have fixed internet at home. For many people, that means calls are paid for out of mobile data.

If your income depends on video calls, data is a real business cost:

• Tutoring? See what the work involves on our online tutoring page.
• Looking at remote jobs? The remote job readiness checker helps you check your setup, and how to become a virtual assistant covers work where many calls can be audio only.
• Want work with fewer calls? Look at ways to make money with your phone.
