Home Internet Data Usage Calculator

Add up a household's monthly data consumption and compare it against the allowance on your broadband plan.

About Home Internet Data Usage Calculator

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.
