Backed by World Bank life expectancy data, PubMed research, and Google Digital Wellbeing statistics, this tool offers a scientifically grounded perspective on digital habits. It's particularly relevant during Digital Detox challenges or when reassessing screen time habits. The calculator also highlights opportunity costs – every hour spent scrolling is an hour not spent reading, exercising, socializing, or traveling.

The Math Behind the Scenes

Core Formula

Total Screen Time = Daily Hours × 365 × (Life Expectancy − Current Age)

Daily Hours = Hours spent on phone per day
Life Expectancy = World Bank data by country
Current Age = Your age in years

Step-by-Step Example

Scenario: A 25-year-old in the United States (life expectancy: 79.1 years) spending 3 hours daily on their phone

Step 1: Remaining years = 79.1 − 25 = 54.1 years

Step 2: Total screen hours = 3 × 365 × 54.1 = 59,239 hours

Step 3: Total years lost = 59,239 ÷ (24 × 365) = 6.76 years

Step 4: Total days lost = 59,239 ÷ 24 = 2,468 days
