Social Media Data Calculator

Why social media eats so much data

Modern social apps are video-first: feeds autoplay reels, stories and clips the moment you open them, often in high definition. An hour of casual scrolling can quietly consume close to a gigabyte on the most video-heavy apps. This calculator uses published average usage rates per app to turn your daily screen time into a monthly data figure.

Data usage per hour by app

• TikTok: about 840 MB per hour — the hungriest mainstream app.
• Instagram: about 720 MB per hour, mostly reels and stories.
• Snapchat: about 600 MB per hour.
• Facebook: about 400 MB per hour.
• X (Twitter): about 300 MB per hour — the lightest of the group.

The formula

Data used = app's hourly rate × (minutes per day ÷ 60)

Example

One hour of TikTok a day: 840 MB × 1 = 840 MB per day, which is about 25 GB over 30 days. Two hours daily pushes it past 50 GB a month — more than many mobile plans include.

Tips to cut social data use

• Switch on each app's data-saver mode to lower video quality on mobile data.
• Turn off video autoplay where the app allows it.
• Do your heavy scrolling on Wi-Fi and keep mobile sessions short.
• Stop apps refreshing in the background in your phone's settings.

Figures are estimates based on typical usage; your real numbers depend on how much video you watch.
