Everyday Life
Phone Data Usage Calculator
Divide your plan's data allowance by your average daily use to see when you will run out.
Formula
Days = plan allowance / daily usage.
How it works
Video streaming eats data fastest — an hour of HD video can use several gigabytes, while messaging and maps use very little.
If your plan runs out early in the month, check which apps use the most in your phone's settings before buying a bigger plan.
FAQs
How much data does streaming use?
Roughly 1 GB per hour at standard quality and 3 GB or more per hour in HD, depending on the service.
Does Wi-Fi usage count?
No — only mobile data counts against your plan. Using Wi-Fi at home stretches the allowance a lot.
What happens when the plan runs out?
It depends on your provider: speeds may drop, extra charges may apply, or data may stop until the next cycle.
