Data Usage Calculator — Monthly Internet Data Estimator
Find out how much internet data you use each month. Enter your daily hours of video streaming, video calls, music, browsing and gaming — the calculator estimates your total usage and shows which activities consume the most data.

How does this calculator work?
Total data = Σ (hours/day × data rate × days). Key rates: SD video ≈ 0.7 GB/h, HD ≈ 3 GB/h, 4K ≈ 7 GB/h, video calls ≈ 1 GB/h, music ≈ 0.15 GB/h. Video streaming dominates most data budgets; gaming active play is low but game downloads are not counted. Compare your total to your ISP data cap.
Formula
How this is calculated
The calculator multiplies your daily hours for each activity by a typical data rate and by the number of days in the period. Data rates vary significantly: streaming in 4K UHD consumes roughly ten times more data than SD, and video streaming in general dominates most household data budgets. The figures used — SD ≈ 0.7 GB/h, HD ≈ 3 GB/h, 4K ≈ 7 GB/h, HD video calls ≈ 1 GB/h, music ≈ 0.15 GB/h, browsing ≈ 0.05 GB/h, online gaming ≈ 0.05 GB/h — are midpoint estimates widely cited by ISPs and streaming services (Netflix, YouTube, Zoom, Spotify). Actual usage varies with video codec (H.265 uses less data than H.264 at the same quality), compression settings, buffering and platform-specific adaptive bitrates.
Gaming data for active play is low (typically 30–100 MB/h), but this estimate excludes game downloads and updates, which can be tens of gigabytes each and are not captured here. Similarly, the browsing estimate covers typical web activity but does not include file downloads, cloud backups or software updates.
Use the result to check whether your total falls within your ISP data cap. Many ISPs offer unlimited plans above a certain threshold, or throttle speeds once a monthly cap is exceeded. If your estimated usage is close to your cap, reducing HD/4K streaming hours or enabling data-saver modes in streaming apps will have the greatest impact.
Frequently asked questions
Netflix uses approximately 0.3 GB/h in low quality, 0.7 GB/h in SD, 3 GB/h in HD (1080p), and 7 GB/h in Ultra HD (4K). The default "Auto" setting adapts to your connection speed, typically landing around HD on a good connection.
Active online gameplay typically uses only 30–100 MB per hour — far less than streaming video. The big data consumers for gamers are game downloads and updates, which are not included here. A new AAA title can require 50–150 GB for a full download.
The biggest win is switching streaming quality from 4K or HD to SD, or enabling data-saver mode in Netflix, YouTube or Disney+. Downloading content on Wi-Fi instead of mobile data, pausing automatic app and OS updates on cellular, and capping video call quality in Zoom or Teams settings are also effective.
