EVERY YEAR AT THIS RATE
40 days
That’s more than a month.
FROM NOW TO AGE 80
5 years 6 months
of your life, gone to the screen.
Projected to age 80. No judgement: some of that time is calls, maps and people you love. But this is what all those quick checks add up to.

The average online adult spends well over 2½ hours a day on social media and video platforms.
2h 39m a day × 365 days = 40 days

“It’s only a couple of hours a day.”
That’s what people say. But 40 days a year isn’t “just” anything. Think about what that time could actually be.
- A real holiday somewhere you’ve always wanted to go
- Unhurried time with the people who matter most
- Enough time to start, or properly grow, a side business
- Finally building the thing that’s been living in your head for years
Now ask yourself honestly. Would you choose to spend it scrolling?
And it’s not just the time you lose. It’s:
- The hollow feeling after.
- The brain fog when you need to focus.
- The guilt that builds as the day goes on.
- The doubt it plants about what you’re capable of.
How the calculator works
It takes your daily screen time and multiplies it by 365 to get your hours on screen each year, then divides by 24 to show them as full days. For the lifetime number, it multiplies that yearly total by the years between your age and 80, and shows the result in years and months of full 24-hour days.
80 is a round assumption, close to average life expectancy in many countries. It’s a projection, not a prediction: the point is the size of the number, not its precision. Everything runs in your browser, and nothing you enter is sent or stored.
How to check your real screen time
iPhone: Settings → Screen Time → See All App & Website Activity. Switch to Week to see your daily average.
Android: Settings → Digital Wellbeing & parental controls. The name can vary slightly by phone.
Questions
How much screen time does the average person have?
According to GWI data reported by DataReportal in October 2025, the average online adult spends well over 2½ hours a day on social media and video platforms alone. Total screen time, including work, messaging and everything else, is higher.
How much screen time is too much?
There’s no single number that’s right for every adult. A more useful question is how much of it you would choose on purpose. If your number surprised you, that’s the place to start.
Is all screen time bad?
No. Calls, maps, work and time with people you love all count as screen time. The calculator doesn’t judge any of it. It shows what the total adds up to, so you can decide what’s worth it.
Why does it project to age 80?
It’s a round number close to average life expectancy in many countries, and it turns a daily habit into a lifetime figure that’s easier to feel. Your real number will be different.
Is anything I enter saved?
No. The calculator runs entirely in your browser. Nothing you enter is sent anywhere or stored.

What is CNTRL?
CNTRL is a discipline system for ambitious people who choose self-improvement.
We believe a good day doesn’t start in the morning. It starts the night before.
Quality sleep gives you a clear head. The first hour after you wake sets the tone for everything that follows. Most of us hand both to our phones: the last scroll before sleep, the first scroll before we’re out of bed.
CNTRL gives you a framework to protect them. Your nights, your mornings, and the real day in between, built around when you actually wake up.
And the best part? The first 14 days free. After that, less than two coffees a month. Or a blue tick on IG.
