Workforce Capacity Calculator

Calculate your team's real productive capacity after meetings, admin, and absence — and plan hiring accordingly.

A 40-hour workweek rarely produces 40 hours of productive work. Subtract meetings, admin tasks, email, PTO, sick days, and training. The average knowledge worker has 60–70% net productive capacity — meaning a 10-person team has the equivalent of 6–7 fully productive people.

The Formula

Capacity % = (Hours − Meetings − Admin) ÷ Hours × 100

In plain English

Productive hours = working hours minus meetings minus admin. Capacity % = productive hours / total hours.

Worked Example

40h − 8h meetings − 5h admin = 27h productive. 27/40 = 67.5% capacity. 10 FTE → 6.75 effective FTE.

Why Effective Capacity Matters for Planning

Headcount is a misleading number for capacity planning. When a team of 10 has only 60% effective capacity, you have the equivalent of 6 productive people. Hiring 2 more to solve a capacity problem may only give you 1.2 effective FTE of additional capacity.

The most impactful lever is often reducing meetings. Studies show knowledge workers attend an average of 8–12 hours of meetings per week. Cutting this by 30% (3–4 hours) increases productive capacity by 10–15%.

Common Mistakes

⚠️

Planning projects based on headcount, not capacity

A 6-person engineering team at 65% capacity has 3.9 effective FTE of productive time. Planning a project that requires 6 FTE of work will consistently miss deadlines. Use effective capacity for sprint and project planning.

⚠️

Ignoring context switching overhead

Fragmented schedules (meetings scattered throughout the day) reduce deep work capacity more than the meeting hours alone. A 2-hour meeting that breaks a 4-hour focus block effectively removes 4 hours of productive time.

⚠️

Not accounting for ramp time in new hire capacity

A new hire at 50% productivity for 3 months adds 0.5 FTE of capacity in that period, not 1 FTE. Factor this into your hiring timeline when planning for project coverage.
