How it works
Video is the biggest share for most homes. Multiply the hours of video a day by the data used per hour, then by 30 days. Add the data for everything else in a month, such as browsing and email.
The share of the cap is the monthly total divided by the cap, times 100. Stay under 100 percent to avoid extra charges where a cap applies.
Worked example
Watching 3 hours of video a day at 3 GB an hour, plus 50 GB of everything else, uses about 320 GB a month. That is 32 percent of a 1,000 GB cap.
Questions
How much data does an hour of video use?
It depends on quality. Standard definition uses much less than high definition, and 4K uses more. Your service may show a figure.
Where do I find my cap?
Your provider's account page or bill lists the monthly allowance, often in GB.
How can I check my real use?
Your provider's account page or your router may show the data used so far this month. Use that to refine the numbers here.
