Headcount Plan

What is a headcount plan?

Headcount plan (in German: Personalplan, planning of staffing needs and personnel costs) denotes the schedule of which positions a company intends to fill in which month, which area they are assigned to and what full costs they cause. Full costs are the gross salary plus all costs that the employer bears in addition, such as social security contributions and workplace. For each task, the plan thus answers three questions: who, from when and at what price.

The headcount plan is a sub-plan of the financial model. From it, personnel expenses flow into the earnings plan, salary payments into liquidity planning and the capacity of sales and customer service into the revenue plan. In technology companies, personnel usually accounts for the largest part of ongoing costs. The plan therefore largely determines the burn rate (the monthly outflow of funds) and the runway (the number of months for which the available funds last). It is prepared in finance together with the heads of area. In a financing round, it justifies the largest part of the use of funds, that is, the statement of what the capital raised is to be spent on.

Content per position

Planning is by position, not by person. Each line contains the function and cost centre (the area to which the costs are allocated), start month and working time as a full-time equivalent (a full position counts as 1.0, a half position as 0.5). Fixed salary, variable pay on achievement of targets and scheduled salary adjustments follow. Added to these are the ancillary costs: employer contributions to social security, statutory levies (for example for maternity protection and insolvency pay), the contribution to the Berufsgenossenschaft (the statutory accident insurance) as well as workplace, equipment and software licences. One-off costs such as fees of recruitment consultants arise in the start month.

Freelancers are shown separately. Participation programmes do not appear as ongoing salary costs. With virtual programmes (VSOP), which predominate in German growth companies, a payment obligation of the company does arise in an exit, however; it belongs in a side calculation. Real shares or options (ESOP), by contrast, work mainly through the dilution of the shareholders.

From gross salary to full cost

Social security contributions are levied only up to the contribution assessment ceilings, that is, up to salary caps set by law. Up to that point, employers bear around one fifth of gross salary as their share of pension, health, long-term care and unemployment insurance (as of 2026: about 21%, depending on the health insurer's additional contribution). With levies, the Berufsgenossenschaft and workplace costs, the full costs of a position are often 25 to 30% above gross salary. This is an order of magnitude, not a fixed rate: the mark-up that actually applies to a company results from its payroll. No contributions are due on the part of salary above the ceilings, so the mark-up falls for high salaries. Contribution rates and ceilings usually change at the turn of the year and belong in the model with the value for the respective plan year.

Two time-related variables are added. The time to fill comprises search, selection and the notice period with the previous employer, which for specialists and managers is often three months. The ramp-up time is the span until a new person reaches full performance, in sales often three to six months. The costs of the position, by contrast, arise in full from the first working day.

Link to revenue, earnings and liquidity

In integrated financial planning, which arithmetically links the earnings, balance sheet and liquidity plans, the headcount plan is a driver: other plan values are derived from it. After their ramp-up time, sales positions generate a stored number of closed deals. Positions in customer service grow with the number of customers according to a fixed service ratio, for example one person per 50 customers. Development positions follow the product planning. If the revenue plan does not fit this capacity, one of the two plans is wrong.

Personnel costs behave in a step-fixed way: they stay the same until the work requires a further position and then rise in one step. In the short term they act like fixed costs; only commissions and bonuses fluctuate with revenue.

For liquidity, the payment dates count. Net salaries usually flow out at month end. Social security contributions are due already on the third-last bank working day of the current month, and wage tax withheld, with monthly filing, by the tenth day of the following month. Annual bonuses and untaken leave lead to provisions at the balance sheet date. Under Section 248(2) of the German Commercial Code (HGB), a company may recognise as an asset in the balance sheet (capitalise) the development costs of internally generated intangible assets such as software, instead of booking them as expense. This does not apply to research costs. The capitalised share of developers' salaries then improves earnings, but not liquidity.

What investors and buyers examine

Investors use the headcount plan to check whether revenue growth and sales capacity fit together, whether the ramp-up times are realistic and what share of the new funds flows into personnel. A topic of its own is key persons: which management positions are still vacant, for example head of sales or finance, and how dependent the company is on individuals.

In due diligence, the examination of the company before an investment or a purchase, the plan is reconciled with actuals: employee list with start date, pay and notice period, payroll journal (the monthly overview of all payslips), bonus and participation commitments. Buyers also look at the predictability of personnel costs. Notice periods and general protection against dismissal, which applies in establishments with more than ten employees after six months of employment, make rapid reduction difficult. The most effective lever when revenue falls short is therefore to postpone planned hires that have not yet been committed.

Worked example

A software company plans four sales positions, each filled at the start of a quarter in January, April, July and October. The fixed salary is EUR 5,000 a month; variable pay is planned separately. Assumed are 22% employer contributions including levies and Berufsgenossenschaft, a realistic order of magnitude for 2026, and EUR 300 a month for workplace, equipment and software. Each person closes no new customers in the first three months, one a month in months four to six and two a month thereafter.

• Full cost per position and month: EUR 5,000 plus EUR 1,100 employer contributions plus EUR 300 = EUR 6,400
• Over the year: 12 × EUR 6,400 = EUR 76,800, which is 28% more than the gross salary of EUR 60,000
• Months of employment in the plan year: 12 + 9 + 6 + 3 = 30
• Personnel costs in the plan year: 30 × EUR 6,400 = EUR 192,000; calculated with gross salary 30 × EUR 5,000 = EUR 150,000, that is, EUR 42,000 too little
• Closed deals with ramp-up time: position from January 15 (0 + 3 + 12), from April 9 (0 + 3 + 6), from July 3 (0 + 3), from October 0; together 27
• Closed deals without ramp-up time: 30 months of employment × 2 = 60
• Overestimated new business at an annual contract value of EUR 10,000 per customer: (60 minus 27) × EUR 10,000 = EUR 330,000
• Realistic new business in the plan year: 27 × EUR 10,000 = EUR 270,000 annual contract value against EUR 192,000 personnel costs
• Following year: 93 closed deals, because the position filled in October reaches full performance only from April; personnel costs 4 × EUR 76,800 = EUR 307,200

A model without ramp-up time shows, at the same costs, more than twice as many closed deals as are realistic (60 instead of 27). The hires pay off fully only in the following year. For runway, this means: in the first year, the build-up of sales consumes markedly more liquidity than a model without ramp-up time and with gross salaries shows.

Distinctions from related terms

• Budgeting: sets binding cost frameworks for a financial year. The headcount plan supplies the largest single item for it and usually extends over several years.
• Career planning: describes development paths and salary bands for existing employees and thereby determines the salary increases that the headcount plan assumes.
• HR business partner: works out an area's staffing needs together with its head and is thus an important source of the plan.

Common mistakes

• Gross salary instead of full costs. Without ancillary costs, the model often underestimates personnel costs by more than a fifth.
• No ramp-up time. Every hire appears fully productive from the first month, and the revenue plan becomes systematically too high.
• Staff turnover not planned. Turnover is the share of the workforce that leaves in a year. With 40 employees and 15% turnover, six replacement hires a year are to be expected, each with new search and ramp-up time.
• Management positions overlooked. When a team grows strongly, it needs additional team leads, which are often missing from the plan.
• No comparison with actuals. If planned and actual starts are not compared monthly in the forecast, delays in filling positions go unnoticed, and the cost and revenue plans drift apart.

Frequently asked questions

How detailed should a headcount plan be?

One line per position, not per person. For larger teams, one line per role type with the number and start months is enough. Names and individual salaries do not belong in a model that goes to investors.

How is variable pay planned?

Separately from the fixed salary and arithmetically linked to target achievement. In the cautious case, it then falls automatically with the lower revenue.

Do freelancers belong in the headcount plan?

Yes, as a group of their own. Investors ask about them specifically, because a permanent activity subject to instructions can be classified as dependent employment (false self-employment, Scheinselbständigkeit). Social security contributions then have to be paid retrospectively for several years, namely the employer and employee shares, by the employer.

Over what period is planning done?

Over the same period as the financial model, in financing rounds usually three to five years. The first twelve to 24 months are planned monthly, later years summarised by role type.

The Roemer Capital view

In engagements in which Roemer Capital works as a finance function on a temporary basis (fractional CFO), it builds the headcount plan into the financial model as a driver. Each sales position generates closed deals according to a stored ramp-up curve, and each position in customer service follows the number of customers. This allows individual assumptions to be justified and changed in the investor conversation, instead of having to defend a revenue curve as a whole.

In the cautious one of the three cases, Roemer Capital postpones hires instead of merely cutting revenue. The model then shows how long the funds last with slowed growth and demonstrates that management can steer the cost side. The runway of 12 to 18 months that Roemer Capital aims for at the start of a process is always calculated with the complete headcount plan including all ancillary costs.
