Interruption impact graph
The chart compares time spent inside interruptions, recovery effort, total daily loss, and projected weekly hours.
Example data table
| Profile | Interruptions/Day | Minutes/Interrupt | Refocus Minutes | Adjusted Daily Loss | Annual Lost Hours |
|---|---|---|---|---|---|
| Light checker | 6 | 2.5 | 4 | 41.40 | 165.60 |
| Average office user | 12 | 4 | 7 | 145.20 | 580.80 |
| Heavy notification user | 20 | 5 | 10 | 286.00 | 1144.00 |
Formula used
1. Daily interruption minutes = Interruptions per day × Minutes per interruption
2. Daily refocus minutes = Interruptions per day × Refocus minutes
3. Base lost minutes = Daily interruption minutes + Daily refocus minutes
4. Complexity factor = 1 + ((Task complexity − 5) × 0.05)
5. Multitask factor = 1 + (Multitasking penalty ÷ 100)
6. Sleep drag minutes = Late-night scrolling minutes × 0.25
7. Adjusted lost minutes = (Base lost minutes × Complexity factor × Multitask factor) + Sleep drag minutes
8. Weekly lost hours = (Adjusted lost minutes × Workdays per week) ÷ 60
9. Annual lost hours = Weekly lost hours × Weeks per year
10. Annual cost = Annual lost hours × Hourly value
11. Deep work loss % = Adjusted lost minutes ÷ Productive daily minutes × 100
12. Fragmentation score combines interruption count, recovery time, alert share, task complexity, and context-switch penalty on a 0 to 100 scale.
How to use this calculator
Enter how often social apps interrupt your day, how long each interruption lasts, and how much recovery time you usually need.
Add your productive hours, focus block length, work schedule, and hourly value to estimate time and money lost over time.
Use notification share, task complexity, multitasking penalty, and late-night scrolling to model hidden attention drag more realistically.

FAQs
1. What does this calculator measure?
It estimates visible and hidden productivity loss caused by social media interruptions. It combines time spent scrolling, recovery delay, task complexity, and schedule assumptions into one impact model.
2. Why is refocus time important?
Most losses happen after the interruption ends. Refocus time captures the minutes needed to mentally return to the original task, which often exceeds the actual scrolling time.
3. What is the fragmentation score?
It is a 0 to 100 indicator of attention instability. Higher values mean more frequent context switching, longer recovery periods, and stronger pressure on deep work.
4. Does this calculator measure only work time?
It is designed mainly for work or study periods. You can still use it for personal productivity by adjusting productive hours, hourly value, and work schedule assumptions.
5. Why include late-night scrolling?
Late-night scrolling can reduce next-day attention quality. This calculator converts part of that behavior into an added focus drag, making the estimate more realistic.
6. What is a good focus block length?
A common range is 25 to 90 minutes depending on task type. Pick the uninterrupted block length you normally consider productive and worth protecting.
7. Can I use salary instead of hourly value?
Yes. Convert your salary into an approximate hourly figure. That makes the annual cost estimate easier to interpret for budgeting, staffing, or performance reviews.
8. How can I reduce interruption severity?
Mute nonessential alerts, batch social checks, separate devices during focus blocks, and protect high-complexity work periods. Even small reductions can recover many hours annually.
