This table shows sample weekly inputs and estimated net focus hours for different team setups.

Formula Used

1. Gross Team Hours
Gross Team Hours = Team Size × (Workdays − Leave Days) × Hours per Day

2. Interruption Hours
Interruption Hours = Team Size × Workdays × Interruptions per Day × Minutes per Interruption ÷ 60

3. Pre-Switch Productive Hours
Pre-Switch Hours = Gross Team Hours − Meeting Hours − Admin Hours − Collaboration Hours − Interruption Hours

4. Context Switch Loss
Context Switch Hours = Pre-Switch Hours × Context Switch Loss %

5. Net Focus Hours
Net Focus Hours = (Pre-Switch Hours − Context Switch Hours) × Focus Efficiency %

6. Focus Ratio
Focus Ratio = Net Focus Hours ÷ Gross Team Hours × 100

7. Target Gap
Focus Gap = Target Focus Hours − Net Focus Hours

These formulas estimate how much weekly time remains for uninterrupted work after meetings, administration, collaboration, interruptions, and switching penalties.

Frequently Asked Questions

1. What does team focus time mean?

Team focus time is the estimated weekly time available for uninterrupted work after removing meetings, administration, collaboration drag, interruptions, and switching losses.

2. Why include context switching loss?

Context switching reduces usable attention after task changes. Even short interruptions can lower concentration and make remaining hours less productive than planned.

3. Should collaboration always be treated as lost time?

No. Collaboration is valuable, but it still reduces uninterrupted deep work time. This calculator separates it so managers can balance teamwork and concentrated execution.

4. What is a good focus ratio?

A good ratio depends on the role. Knowledge teams often aim for 45% to 65% focus time, while support-heavy teams may operate below that range.

5. How is the deep work score interpreted?

The score combines focus ratio, efficiency, and switching control into one view. Higher values suggest healthier conditions for sustained, high-value work across the team.

6. Can I use weekly instead of daily averages?

Yes. Convert weekly totals into daily averages before entering them. That keeps the formulas consistent and makes scenario comparisons easier.

7. Why are leave days included?

Leave days reduce total available capacity. Including them creates a more realistic weekly estimate, especially for shared teams with shifting attendance.

8. What should I do if focus gap hours are high?

Reduce meeting load, batch admin work, protect larger focus blocks, and limit interruptions. Those changes often improve net focus hours quickly.
