Headcount Planning Calculator
Headcount planning translates business growth targets into concrete hiring needs. By combining projected revenue growth, current revenue-per-employee ratios, expected attrition, and planned new roles, HR and finance teams can forecast how many people need to be hired, the required hiring velocity, and the budget impact. This is typically done during annual planning cycles but should be revisited quarterly.

Hiring Needs
Projections assume linear scaling of revenue per employee. Actual hiring needs depend on productivity gains, automation, organizational restructuring, and market conditions.
