At least for me personally, usage varies wildly depending on what’s happening in the real world. On my family plan, my wife and I each use ~8-10 per month, but external factors cause much higher usage. For example, the car is on the account and acts as a WiFi hotspot for all non-cellular devices. We took a 13hr road trip in August and plan usage that month was 42gb.
