Data Usage Calculator. Enter your monthly online habits — emails, web surfing, music streaming, video streaming, gaming, and more — into the Data Usage Calculator to get your estimated total monthly data consumption in GB. See a breakdown of how each activity contributes to your usage so you can choose the right internet plan. Also try the Recessed Lighting Calculator.
For light users (email, occasional browsing), 5–10 GB/month is typically sufficient. Moderate users who stream SD video and browse social media regularly may need 20–50 GB. Heavy users who stream HD/4K video, game online, and video call frequently can easily use 100–500 GB or more per month. Use the calculator above to get a personalized estimate.

It depends on the video quality. An SD movie (~2 hours) uses approximately 1.4 GB, an HD movie uses around 6 GB, and a 4K UHD movie can consume up to 14–20 GB. If you watch several movies per week, video streaming will likely be your biggest source of data consumption.
Multiplayer online gaming typically uses between 40–150 MB per hour depending on the game. While this is much less than video streaming, downloading game updates and patches can use several gigabytes at once. The calculator estimates roughly 75 MB per hour for gaming sessions.
Each activity has a known average data rate (e.g., HD streaming ≈ 3 GB/hr, music streaming ≈ 72 MB/hr). You multiply the data rate by your hours or number of uses per month, then add up all activities. The formula is: Total Usage = Σ (Activity Rate × Monthly Quantity) for all activities.
Mobile data usage refers to the total amount of data transferred over a cellular or Wi-Fi connection while browsing, streaming, gaming, or using apps. It is measured in megabytes (MB) or gigabytes (GB). Exceeding your plan's data cap can result in throttled speeds or overage charges depending on your provider.
Standard-quality music streaming uses approximately 43–72 MB per hour. At high quality (320 kbps), this rises to about 150 MB per hour. Streaming 2 hours of music per day for a month at standard quality would use roughly 2–4 GB.
Yes — video calls use roughly 0.5–1.5 GB per hour depending on the platform and video quality. A one-hour HD Zoom or Teams call can consume about 1.2–1.5 GB. If you work remotely and attend multiple video meetings daily, this can add 20–40 GB to your monthly usage.
Social media usage with photos and short video clips typically uses about 90 MB per hour of active scrolling. Photo-heavy platforms like Instagram consume more than text-based ones. Heavy social media use of 2–3 hours per day can add up to 5–8 GB per month. You might also find our calculate Grocery Recommended Monthly Grocery Budget useful.
