About these estimates
Why your data use can vary
Quality changes everything
Higher video quality, autoplay, downloads, and background refreshes can use much more data.
Apps do not use data alone
The activity cards are separate estimates, not a combined allowance you can use all at once.
Your data stays private
The calculator runs in your browser and does not send your data balance anywhere.
How accurate is this data calculator?
It uses practical average rates. Actual use depends on video quality, app features, ads, downloads, background activity, and your device.
Can I use every estimate at the same time?
No. Each card shows what your full remaining allowance could provide for one activity. Mixing activities reduces the time.
Does 1 GB always mean the same amount?
This calculator uses 1 GB = 1,024 MB, which is commonly used for device data calculations.
