Example data table
Sample values show how the calculator can compare periods or teams.
| Period | Planned Hours | Actual Hours | Productive Hours | Completed Tasks | Quality Score | Efficiency Score |
|---|---|---|---|---|---|---|
| Week 1 | 40 | 41 | 30 | 21 | 88% | 77.60% |
| Week 2 | 40 | 42 | 31 | 22 | 91% | 80.92% |
| Week 3 | 40 | 39 | 33 | 24 | 94% | 87.45% |
Formula used
Available Hours = Actual Hours − Break Hours
Time Utilization = (Productive Hours ÷ Available Hours) × 100
Task Completion = (Completed Tasks ÷ Planned Tasks) × 100
Deep Work Ratio = (Deep Work Hours ÷ Productive Hours) × 100
Meeting Share = (Meeting Hours ÷ Available Hours) × 100
Interruption Score = 100 − (Interruptions × 4)
Rework Score = 100 − ((Rework Minutes ÷ Productive Minutes) × 180)
Schedule Score = 100 − (|Actual Hours − Planned Hours| ÷ Planned Hours × 100)
Overtime Score = 100 − ((Overtime Hours ÷ Planned Hours) × 120)
Overall Efficiency = 22% Time Utilization + 16% Task Completion + 15% Quality + 12% Deep Work + 10% Interruption Score + 10% Rework Score + 8% Schedule Score + 4% Meeting Score + 3% Overtime Score
Scores are limited to practical ranges so a single extreme value does not distort the final result.
How to use this calculator
- Enter the person or team name and the period you want to review.
- Fill planned hours, actual hours, and break hours for the period.
- Add productive hours, deep work hours, and meeting or admin hours.
- Enter planned tasks, completed tasks, interruption count, and rework minutes.
- Set the quality score and overtime hours, then choose a target efficiency.
- Press the calculate button to place the result above the form.
- Review the component scores, efficiency rating, and improvement recommendations.

Frequently asked questions
1. What does the work efficiency score represent?
It combines time use, completion rate, quality, focus, interruptions, rework, scheduling, meetings, and overtime into one performance score.
2. Why track deep work separately?
Deep work highlights uninterrupted execution time. A higher deep work ratio usually supports stronger output quality and faster completion.
3. Can task completion exceed 100 percent?
Yes. It can happen when extra tasks are finished. The display shows the real rate, while the weighted score stays within practical limits.
4. How are interruptions handled?
Each interruption reduces the interruption score. That keeps frequent context switching visible in the final efficiency result.
5. Why include meeting or admin hours?
Meeting load affects available execution time. Tracking it helps explain lower focus, higher overtime, or reduced productive output.
6. What is quality-adjusted output?
It multiplies completed tasks by the quality score percentage. That shows how much finished work still meets your expected standard.
7. Should overtime always be treated negatively?
Not always, but recurring overtime can hide poor planning or overload. The score applies a light penalty to keep workload sustainability visible.
8. When should I use this calculator?
Use it for daily, weekly, or monthly reviews, team check-ins, workload planning, coaching conversations, and process improvement tracking.
