How to Use This Tool
Enter your average daily total screen time, selecting whether the value is in hours or minutes. Add your typical screen time within one hour of bedtime, and choose your primary type of screen use from the dropdown menu.
Input your average daily sleep duration in hours, then select your current screen break habits. Click Calculate to see your personalized impact breakdown, or Reset to clear all fields and start over.

Formula and Logic
Results are calculated using commonly referenced lifestyle and sleep research benchmarks:
- Sleep impact estimates assume every 30 minutes of screen time within one hour of bed delays sleep onset by 5 minutes.
- Productive screen time is calculated by applying a fixed productivity percentage to total screen time based on primary activity: Work/Education (80%), Reading (70%), Social Media (20%), Streaming/Gaming (10%), Other (50%).
- Weekly screen time is total daily screen time multiplied by 7.
- Digital Wellbeing Score (1-10) is derived from sleep duration, bedtime screen use, break habits, productive time, and total daily screen time, with a base score of 5 adjusted by category-specific factors.
Practical Notes
Adjust your inputs to reflect weekend vs. weekday usage for more accurate results. If you use multiple devices, sum total screen time across phones, tablets, computers, and TVs.
- Screen time before bed includes any device use within 60 minutes of your intended sleep time, including scrolling, streaming, or reading.
- Productivity percentages are estimates; adjust your primary activity selection if you use screens for mixed purposes (e.g., work and social media) by choosing the dominant activity.
- The Digital Wellbeing Score is a relative metric, not a clinical assessment. Use it to track changes in your habits over time, not as a diagnostic tool.
- For accurate sleep duration input, use your average over the past 2 weeks, including naps if they are part of your regular routine.
Why This Tool Is Useful
Many people underestimate how daily screen habits affect sleep, productivity, and overall routine. This calculator provides a quick, personalized snapshot of your current screen time impact without requiring account sign-ups or data tracking.
Use the results to identify small, actionable changes: for example, reducing bedtime screen time by 30 minutes can cut sleep delay by 5 minutes, or adding regular breaks can improve your wellbeing score.
It is designed for general consumers, parents tracking family habits, and anyone looking to balance digital use with personal planning and home life.
Frequently Asked Questions
Is this calculator clinically validated?
No, this tool uses general lifestyle research benchmarks to provide estimates. It is not a substitute for medical or sleep professional advice. Consult a healthcare provider for concerns about chronic sleep issues or screen addiction.
Can I use this for my child’s screen time?
Yes, but adjust inputs to reflect child-specific guidelines: the American Academy of Pediatrics recommends no more than 1-2 hours of recreational screen time for children over 2, and consistent limits for all ages.
Why does my wellbeing score change when I adjust break habits?
Regular screen breaks reduce eye strain, improve focus, and lower mental fatigue, all of which contribute to higher digital wellbeing. The score rewards consistent break habits with higher ratings.
Additional Guidance
Start by tracking your screen time for 3 days using your device’s built-in screen time tracker to get accurate input values. Small changes, like setting a 30-minute screen curfew before bed, can have measurable impacts on sleep quality.
- Use the weekly screen time estimate to set monthly limits: for example, if your weekly total is 50 hours, aim to reduce by 2-3 hours the following week.
- Pair screen breaks with non-digital activities: a 5-minute walk, stretching, or hydration can boost the benefits of regular breaks.
- Re-calculate your results every 2 weeks to track progress as you adjust your screen habits.
