How it works
The formula is:
((Current headcount − Previous headcount) ÷ Previous headcount) × 100
A positive result is growth; a negative result is a reduction. Use the same definition of "headcount" (for example, whether contractors are included) at both points.
Worked example: Going from 80 to 100 people is ((100 − 80) ÷ 80) × 100 = 25% growth, a net change of +20.
For the full background — what it measures, why it matters and how to read it — see the headcount growth guide.
How to read the result
Growth rate puts hiring and attrition into net terms: you can hire steadily and still see flat headcount if departures match arrivals. Read it together with turnover and retention to understand what is driving the net figure.
Compounding matters — a steady percentage adds more people each period as the base grows. Plan capacity, onboarding and management span for the people behind the percentage, not just the percentage.
Common mistakes
- Changing the definition of headcount between the two points (e.g. including contractors only once).
- Comparing periods of different lengths.
- Reading growth without turnover, so churn hidden inside net growth goes unnoticed.
- Planning only for the percentage and not for onboarding and management capacity for the actual people.
