How to Calculate Internet Data Usage
What is Internet Data Usage?
An internet data usage calculator estimates monthly broadband consumption based on daily online activities. Essential for choosing the right data plan and avoiding overage charges on capped connections.
Formula
monthly_usage_gb = (video_hours × bitrate_gbph) + (calls × hours × mbph/1000) + (browsing × pages × mb_per_page)
- video
- Video hours (hours) — Streaming (HD ≈ 3 GB/hr, 4K ≈ 7 GB/hr)
- calls
- Video calls (hours) — Zoom/Teams (1.5 Mbps = 0.68 GB/hr)
- browse
- Browsing (hours) — Web pages (~10 MB/page)
- total
- Total data (GB) — Monthly consumption
