Your daily scroll habit, converted into years of life, books unread, skills unlearned, and money unmade. Painfully accurate.
Social media platforms are engineered for maximum time extraction. Instagram's algorithms, TikTok-style Reels, YouTube's autoplay, and WhatsApp's social obligation loops are optimized by billions of dollars of engineering to keep you scrolling. The product is your attention. The customer is the advertiser. Understanding this changes how you think about your screen time.
The opportunity cost of screen time isn't just what you could have done instead — it's compound. An hour spent scrolling Instagram at 25 is an hour not spent building a skill, exercising, sleeping, or investing. These alternatives compound: skills learned at 25 pay dividends at 35. Exercise habits at 25 reduce healthcare costs at 55. Time, not money, is the truly scarce resource.
The life-years metric in this calculator is deliberately provocative. If you spend 4 hours/day on social media from age 20 to 60, you spend approximately 6.7 years of your waking life on these platforms. That's not a judgement — it's arithmetic. What would you do with 6 years of life if you could have them back?
The point isn't abstinence. Passive consumption of entertainment is legitimate leisure. The question is intentionality: are you choosing to spend this time on these platforms, or are the platforms choosing to extract this time from you? One is leisure. The other is a tax.
