Headcount Planning Calculator
Calculate FTE requirements from revenue targets.
About this calculator
The Headcount Planning Calculator translates a revenue target into a staffing plan by dividing Target Annual Revenue by Revenue Per Employee and rounding up to the nearest whole person -- the same "revenue-per-FTE" ratio investors and boards use to sanity-check a growth plan's staffing intensity. Raising Target Annual Revenue increases Required Headcount in the same direction, while raising Revenue Per Employee moves the ratio the opposite way: a company that gets more efficient per hire needs fewer new people to hit the same revenue number. Current Headcount and the Fully Loaded Cost per Employee do not change how many people the target requires -- the Fully Loaded Cost only feeds the dollar side, Projected Annual Labor Cost -- but Current Headcount does change how many people you must add, since Net New Hires is the gap between Required Headcount and what you already have.
Annual Turnover Rate is a wholly separate line: it never bears on how many roles the business ultimately needs, but it drives Replacement Hires, the extra recruiting required just to backfill people who leave. Total Hires Needed sums the growth hires and the replacement hires so recruiting can budget for both at once. What this does not account for: seasonality, part-time or contractor mix, hiring lead time, or attrition concentrated in specific roles rather than spread evenly across headcount.

How to Use This Calculator
- Enter your target annual revenue.
- Set the average revenue generated per employee (revenue per head).
- Input current headcount and the fully loaded cost per employee (salary + benefits + overhead).
- Set the expected annual turnover rate and the expected Annual Revenue Growth Rate for Year 2.
- Review the target headcount, headcount gap, projected total labor cost, and the Year 2 Projected Headcount.

Frequently Asked Questions
Why doesn't Annual Turnover Rate change the Required Headcount number?
Required Headcount only measures how many roles the revenue target needs -- Target Annual Revenue divided by Revenue Per Employee. Turnover Rate feeds a separate output, Replacement Hires, which estimates how many additional people you'll recruit just to backfill departures, not how many total roles exist.
What happens if my current headcount already exceeds what the revenue target requires?
Net New Hires is floored at zero, so the calculator never reports a negative hiring need. If Current Headcount is already above Required Headcount, Net New Hires shows 0 -- the tool doesn't recommend layoffs, it only tells you whether more hiring is needed to hit the target.
Why does raising Revenue Per Employee lower the Required Headcount instead of raising it?
Revenue Per Employee is the productivity assumption in the denominator: Required Headcount equals Target Annual Revenue divided by Revenue Per Employee. A higher ratio means each hire is assumed to generate more revenue, so fewer hires are needed to reach the same target -- that's why the two move in opposite directions.
Does the Fully Loaded Cost per Employee affect how many people I need to hire?
No. It only feeds the cost-side outputs -- Projected Annual Labor Cost and Incremental Labor Cost -- and has no effect on Required Headcount, Net New Hires, or Replacement Hires. Use it to see what the plan costs, not how big the team needs to be.
What does the Year 2 Projected Headcount assume?
It reapplies the same Revenue Per Employee ratio to a Year 2 revenue figure grown from Target Annual Revenue by the Annual Revenue Growth Rate you entered. It assumes revenue-per-employee productivity stays constant into Year 2, which will understate headcount needs if productivity is expected to decline as the team scales.
