How Much of My Life Do I Spend on Screens?
Multiply your daily screen hours by 365.25 for the year, then divide by 24 for full days. Three and a half hours a day is 1,278 hours a year, about 53 full days. At the global average of 6 hours 38 minutes online a day, 62 years of adult life adds up to roughly 17 years on screens.
How to Use the Screen Time Calculator
- Check your phone's own figure (Screen Time on iPhone, Digital Wellbeing on Android) and enter your hours per day.
- Set days per week, for example 5 if you only count workdays.
- Optionally add your age to compare with WHO and AAP guidance, and an hourly rate to see an illustrative value of the time.
Screen Time Per Year: Quick Table
| Hours a day | Hours a year | Full days a year | Years over 50 years |
|---|---|---|---|
| 1 | 365 | 15.2 | 2.1 |
| 2 | 731 | 30.4 | 4.2 |
| 3.5 | 1,278 | 53.3 | 7.3 |
| 5 | 1,826 | 76.1 | 10.4 |
| 6 h 38 min (global average) | 2,423 | 100.9 | 13.8 |
| 8 | 2,922 | 121.8 | 16.7 |
Formula: hours per year = hours per day × 365.25; full days = hours per year ÷ 24; lifetime years = hours per day × years ÷ 24. The calculator shows the yearly figures; use the last column or the formula for a whole-life total.
Recommended Screen Time by Age
| Age | Guidance |
|---|---|
| Under 2 | No screen time (WHO). The AAP allows video calls with family. |
| 2 to 4 | No more than 1 hour a day of sitting screen time; less is better (WHO) |
| 5 to 17 | No single official number; limit recreational screen time and protect sleep and activity. Under 2 hours is a widely used benchmark. |
| Adults | No official cap; break up long sitting time and meet activity guidelines |
This is general public-health guidance, not medical advice. Talk to a doctor about specific concerns, especially for a child.
About the Optional Dollar Value
Enter an hourly rate and the calculator multiplies it by your yearly screen hours. It's a way to feel the scale of the time, not a real loss: the alternative to screen time might be rest, family or chores, none of which are paid.
Common Mistakes
- Guessing instead of checking. Your phone's built-in report is often higher than a guess.
- Counting only the phone. Laptop, TV and tablet time count too if you want the full picture.
- Treating the dollar figure as lost income. It's illustrative only.
See the same time as squares on your life in weeks grid, or turn an hour a day of scrolling into reading time with the books before you die calculator. Want to cut down? Track a daily screen-free habit in the habit tracker. This tool doesn't read your device data; it only uses the numbers you type.
Who Uses the Screen Time Cost Calculator?
- Personal check-in: turn daily screen hours into days and years to see the real total.
- Parents: compare a child's screen time with recommended limits by age.
- Productivity goals: see what cutting an hour a day would give back in a year.
How the Screen Time Cost Calculator Saves You Time
Converting hours a day into a yearly and lifetime total takes several multiplications. The calculator does them all and shows the figures side by side.
