DataUsageCalc estimates how much mobile data you use in a month, so you can choose a plan that fits instead of guessing.
• Enter daily hours for video streaming in SD, HD or 4K, web browsing, social media, music and video calls
• Add monthly downloads and set how many days a month you use your phone
• Adjust the typical MB-per-hour rates to match your own apps
• Start fast with Light, Typical, Heavy or Gamer presets
• See the monthly total, daily average and how much each activity takes
• Compare against your current plan and get a suggested plan size with 10% headroom
• Add family lines: give each person a Light, Typical, Heavy or Gamer habit, your own inputs or a custom GB figure, and check the total against a shared plan
• Compare plan prices: enter the monthly price, included GB and price per extra GB, and see plans ranked by total cost with the cost per GB
• Work out download time from file size and connection speed, in Mbps, MB/s or Gbps, with an optional overhead allowance
• Copy the result to paste into a message or note
• Save scenarios, such as home and travel, and come back to them later
