This is an estimate. Actual usage varies based on
video quality, device, app behaviour, network conditions, downloads,
autoplay features and content consumed.

What affects my estimate?
Video quality, autoplay, downloads, app settings, device type and network conditions can all change actual usage. Enter what you normally do; the calculator converts it into a monthly guide rather than an exact bill.

How Data Calculator Works
- 1 hour of social media = 330 MB
- 1 hour of web browsing = 60 MB
- 1 hour of Instant Messaging = 160 MB
- 1 hour of streaming music = 125 MB
- 1 hour of video streaming (SD) = 350 MB
- 1 hour of video streaming (HD) = 1.2 GB
- 1 hour of video streaming (4K) = 2.4 GB
- 1 hour of video calls = 160 MB
Note: Data estimates are not based on time alone. For apps like WhatsApp, usage also depends on the volume and type of content shared — such as images, videos, voice notes, and files, especially in group chats.
Roaming note: This calculator does not reflect roaming network conditions, allowances or charges. Check your roaming plan before travelling.

Frequently asked questions
How accurate is the Data Calculator?
The Data Calculator provides an estimate of your monthly data consumption based on the information provided. Actual usage may vary depending on video quality settings, device type, application behaviour, network conditions, downloads, autoplay features and content consumed.
What is headroom?
Headroom is a buffer added to your estimate for app updates, background activity, unexpected downloads and heavier-than-usual usage.
Why does video quality matter?
SD uses less data, HD uses more, and Ultra HD/4K can consume data much faster because it streams higher-resolution video.
Can I use this for multiple devices?
Yes. Increase the number of devices and the calculator will estimate usage across all selected devices.
