How Capacity Planning Calculator works
The Capacity Planning Calculator computes gross payroll hours, deducts team-wide PTO and holiday hours to find net attendance, applies your productive focus factor percentage, and compares the resulting capacity against your planned demand.
Productive Capacity = ((Team * Days * Hours/Day) - PTO) * (Focus% / 100); Gap = Productive Capacity - Demand.
Also expresses your capacity buffer or shortfall in equivalent Full-Time Equivalents (1 FTE = Days * Hours/Day * Focus%).
Capacity Planning Calculator Quick Reference & Input Guide
Review the input parameters, allowed value ranges, and worked reference cases for the Capacity Planning Calculator below before running your calculation.
| Parameter / Scenario | Default / Sample Value | Rule or Allowed Range | Output / Usage Note |
|---|---|---|---|
| Input: Team headcount (FTEs) | 8 | Range: 1 to 10000 | Required workspace parameter |
| Input: Working days in period | 10 | Range: 1 to 365 | Required workspace parameter |
| Input: Standard hours per workday | 8 | Range: 0.5 to 24 | Required workspace parameter |
| Input: Total team PTO, holidays & leave | 24 | Range: 0 to 100000 | Required workspace parameter |
| Worked Case 1: 2-week sprint for 8 engineers (10 days, 8 hr/day, 24h PTO, 75% focus, 420h demand) | Preloaded / test values | Gross Hours = Team * Days * HoursPerDay; Net Attendance = Gross - PTO; Productive Capacity = Net Attendance * (FocusFactor% / 100); Utilization = Demand / Productive Capacity | Gross hours = 640.0 hr. Subtracting 24.0 hr of PTO leaves 616.0 net attendance hours. At a 75% focus factor, productive capacity is 462.0 hr (57.75 hr/person). Against 420.0 hr of demand, utilization is 90.91% with a +42.0 hr (+0.73 FTE) buffer. |
| Worked Case 2: Spotting a 100% focus-factor trap | Preloaded / test values | Gross Hours = Team * Days * HoursPerDay; Net Attendance = Gross - PTO; Productive Capacity = Net Attendance * (FocusFactor% / 100); Utilization = Demand / Productive Capacity | If the same 8-person team planned 550 hours assuming 100% focus (616h net), their true utilization at 75% focus (462h capacity) would be 119.05% (-88.0 hr / -1.52 FTE deficit). |
How to use Capacity Planning Calculator step by step
Gather your team's upcoming PTO schedule and backlog hour estimates before sprint or quarterly planning.
Enter headcount, working days, and daily hours
Input the number of people on the team, working days in the cycle (e.g., 10 days for a 2-week sprint), and standard hours per day.
Subtract team PTO and set focus factor %
Enter combined vacation/holiday hours for the period and set a realistic focus factor (e.g., 75%).
Compare productive capacity against workload demand
Input your planned project demand in hours and click Calculate Team Capacity to see utilization rate and FTE buffer or deficit.
Worked examples for Capacity Planning Calculator
Compare a balanced 2-week sprint against an over-committed quarterly roadmap.
2-week sprint for 8 engineers (10 days, 8 hr/day, 24h PTO, 75% focus, 420h demand)
Gross hours = 640.0 hr. Subtracting 24.0 hr of PTO leaves 616.0 net attendance hours. At a 75% focus factor, productive capacity is 462.0 hr (57.75 hr/person). Against 420.0 hr of demand, utilization is 90.91% with a +42.0 hr (+0.73 FTE) buffer.
Spotting a 100% focus-factor trap
If the same 8-person team planned 550 hours assuming 100% focus (616h net), their true utilization at 75% focus (462h capacity) would be 119.05% (-88.0 hr / -1.52 FTE deficit).
Deduct company-wide holidays across all FTEs
If a 1-day public holiday falls inside an 8-person sprint, multiply 8 people * 8 hours = 64 hours and add that to your PTO & holiday box.
How to interpret the Capacity Planning Calculator output
Aim for 80% to 90% utilization of productive capacity so unplanned bugs do not derail delivery.
The headline result shows Productive Capacity in hours and your Utilization Rate percentage. Breakdown cards show Gross calendar hours, Net attendance hours after PTO, Capacity surplus or deficit (in hours and FTEs), and Productive hours per team member.
Input limits, assumptions, and related tools
Remember that hours are not interchangeable across specialized roles.
PTO hours must be strictly less than gross team hours so net attendance stays positive. Aggregate hour math assumes tasks can be distributed across team members; if frontend, backend, or QA skills are bottlenecked, run a separate capacity check for each role.

Open toolCapacity Planning Calculator: common questions
Answers about using Capacity Planning Calculator and understanding its results.
What is the difference between gross capacity and productive capacity?
Gross capacity is the raw calendar total (Headcount * Working Days * Hours/Day). Productive capacity subtracts PTO and holidays first, then multiplies by your Focus Factor (typically 70% to 80%) to account for meetings, Slack/email, and administrative overhead.
What is a realistic focus factor for engineering and operations teams?
Scrum and operations benchmarks typically use 70% to 80% (5.6 to 6.4 productive project hours per 8-hour day) for individual contributors, and 50% to 65% for tech leads or staff who handle on-call triage and ceremonies.
How do I interpret a Utilization Rate above 100%?
A utilization rate above 100% means your planned task demand exceeds your team's productive capacity. The calculator displays the exact hour deficit and the equivalent FTE headcount gap so you can de-scope work or add resources.
Should PTO be entered per person or for the entire team?
Enter combined PTO and holiday hours for the entire team in 'Total team PTO, holidays & leave'. For example, if 3 people each take 1 day (8 hours) off during the sprint, enter 24 hours.
