Add up a household's monthly data consumption and compare it against the allowance on your broadband plan.
Consumption is the product of time, rate and concurrent users, scaled to a 30-day month. The allowance comparison matters because overage is usually billed at a far higher effective rate than the plan itself. Data caps are enforced silently until they are breached, and a single 4K household connection can consume more than an entire household did a few years ago.
