How to Use This Calculator

  • Enter your projected business growth rate and expected attrition rate. These two inputs drive everything, so use your most realistic estimates.
  • Input the average annual salary across your workforce. The calculator automatically applies a 1.3x loading factor to account for benefits, taxes, and overhead.
  • Enter your total approved hiring budget for the planning period.
  • Add each department with its current headcount and any open vacancies. If a specific department has a significantly different attrition rate, enter it directly otherwise the calculator uses your company-wide rate.
  • Click Run Gap Analysis to generate your results.

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.
