FAQ
Q: How do I calculate headcount needed for a team? A: Required Headcount = Total Work Volume (hours) ÷ (Available Hours per Employee × Utilisation Rate). For example: 10,000 hours of annual work ÷ (1,750 hours per FTE × 0.80 utilisation) = 7.14 FTEs, rounded up to 8. Always add an attrition buffer — if annual turnover is 15%, add 15% to your headcount to maintain capacity.
Q: What is the difference between headcount and FTE? A: Headcount is the raw number of people on payroll. FTE (full-time equivalent) converts all employees to a full-time baseline. A part-time employee working 20 hours per week equals 0.5 FTE. Two 20-hour part-timers = 1 FTE. Headcount matters for office space and benefits; FTE matters for workload capacity and budget planning.
Q: How do I plan headcount for a growing company? A: Start with your current capacity, map it against your projected workload for 12–24 months, then apply your growth rate assumption. Factor in ramp time (typically 60–90 days before a new hire is fully productive), attrition rate, and any planned automation. Our calculator models all of these inputs simultaneously to give you a hire-by-quarter roadmap.
