A loading factor of 1.3× is applied to average salary to account for benefits, taxes, and overhead. Hiring Priority is ranked by headcount gap as a percentage of current headcount.

How to Read the Results
- The four summary cards give you the headline numbers at a glance: current headcount, required headcount, total hiring gap, and whether your budget covers it.
- Required Headcount is your forward-looking workforce target. It accounts for both your growth ambitions and the natural attrition you should expect to replace.
- Headcount Gap is the number of people you need to hire to close the distance between where you are today and where your business needs you to be.
- Hiring Priority tells you where to focus first. High priority departments have a gap greater than 30% of their current headcount and signal immediate recruitment action.
- The Budget Analysis section tells you whether your approved budget is sufficient. A deficit does not mean you cannot hire it means you need to phase your hiring plan or revisit your budget assumptions.
- Results are sorted by hiring priority so the most critical departments always appear at the top of the table.
