Data usage estimates are built from typical per-hour rates for each activity: standard-definition video streaming uses roughly 0.7GB per hour, HD around 3GB per hour, and 4K considerably more at around 7GB per hour, since higher resolution simply means more data has to be sent to render each frame.
Lower-bandwidth activities like music streaming and general web browsing use far less — typically well under 200MB per hour — while video calls sit in the middle, varying with resolution and how many participants' video feeds are being received at once.
These are industry-typical averages rather than measurements of your specific apps and settings, so if you want a precise figure, most phones and routers have a built-in data usage tracker that shows real per-app consumption over the past billing period.
It uses typical published data rates per activity, which vary in practice by app, video resolution/bitrate, and screen size. For an exact figure, check your phone's or router's built-in data usage tracker.
Higher resolution video contains far more visual information per frame, so streaming services send proportionally more data to display it — 4K can use roughly 10x the data of standard definition.
No — this estimates total data consumption regardless of connection type. If most of your usage happens over WiFi at home, only the portion done on mobile data (cellular) counts against a phone plan's data cap.
Run the calculator for each person's habits separately and add the monthly totals together to estimate the combined usage against a shared/family data plan.
