Data Usage Calculator
Estimate how much internet data your everyday streaming, calls and browsing use each month — and see whether your plan's cap can take it.
Enter how many hours per day you spend on each activity. We estimate your monthly data and compare it to your plan cap.
How much data do your activities use?
Your internet speed (measured in Mbps) and your monthly data usage (measured in GB) are two different things. Speed is how fast data arrives; usage is how much arrives over a month. This calculator focuses on the second: it multiplies your daily hours of streaming, calling and browsing by realistic per-hour data rates, then scales to an average month (30.44 days) so you can see whether your plan's cap is comfortable, tight or already blown.
The estimates below are typical figures — your real usage varies with quality settings, the apps you use and how much you download. Treat the result as a planning guide, not a meter reading.
Typical data use per hour
| Activity | Approx. data per hour | Notes |
|---|---|---|
| HD video (1080p) | ~3 GB | Netflix, YouTube and similar at high definition |
| 4K / Ultra HD video | ~7 GB | The single biggest data consumer |
| Video call | ~1.3 GB | Zoom/Meet group HD call; lower for audio-only |
| Music streaming | ~70–150 MB | Depends on quality; lossless is much higher |
| Browsing & social | ~100–250 MB | Heavier when feeds autoplay video |

Frequently asked questions
How much data does streaming video use?
Roughly 3 GB per hour for 1080p HD and around 7 GB per hour for 4K, though this drops sharply at lower quality settings. 4K streaming is the fastest way to use up a data cap, so lowering the resolution is the easiest saving.
How much data do video calls use?
A group HD video call uses roughly 1.3 GB per hour. Turning your camera off or using audio-only can cut that to a fraction, which is useful on a capped or mobile connection.
Why does this show GB and not Mbps?
GB is a volume — the total amount of data you move in a month, which is what data caps limit. Mbps is a speed — how fast data arrives at any moment. A fast connection can still hit a low monthly cap, so the two are measured separately.
How accurate is this data usage estimate?
It uses typical per-hour figures and assumes an average 30.44-day month, so it is a planning estimate rather than an exact meter. Your real total depends on streaming quality, the apps you use and any large downloads or updates.
How can I reduce my monthly data use?
Lower streaming quality from 4K to HD or HD to SD, download media on Wi-Fi instead of streaming on mobile, turn off video autoplay in social apps, and use audio-only for routine calls. Streaming quality is by far the biggest lever.
