The costs associated with a vacant position often arise before they become apparent in the form of lost revenue, project delays, increased workload for the team, or customer churn.
Key Points at a Glance
- The costs associated with a vacant position include lost value creation, the burden on the team, management overhead, and recruiting costs.
- Formula: daily value contribution of the position × number of days the position has been vacant × role factor.
- As a conservative estimate, calculate based on annual salary plus employer costs; for sales or key roles, calculate based on the expected value contribution.
- The biggest mistake: underestimating the length of the vacancy—the business impact of a vacancy often begins before the job posting goes out and doesn’t end until the new hire is fully productive.
- A vacant position typically incurs higher costs than the salary saved—which justifies additional recruiting resources or outside assistance.
At first glance, a vacant position seems like a missing salary on the expense side. In practice, this is rarely the case. You save on the salary in the short term. At the same time, value creation suffers, work gets spread across overburdened teams, projects fall behind schedule, leads go unaddressed, managers spend hours in endless coordination loops, and candidates drop out because the process takes too long.

Why a Job Opening Is Rarely Just an HR Problem
A vacancy arises in the recruiting department. The costs are incurred in the business. That is the point that is often overlooked in many cost analyses.
In a sales role, there’s a lack of meetings, pipeline, deals, and pressure to secure renewals. In a software engineering role, releases are delayed. In finance, gaps emerge in reporting, forecasting, or closing processes. In HR, recruiting capacity declines, which prolongs the time it takes to fill new vacancies. An open position is like a small crack in a window: from the outside, it looks stable until pressure builds up.
The Federal Employment Agency uses the “time to fill” as a metric for the period between the desired hire date and the date a reported job opening is closed. According to the methodology, a long vacancy period indicates a more difficult search and potential skilled-worker shortages. The same logic applies within a company: the longer a key position remains unfilled, the greater the economic damage.
What costs are associated with a vacant position?
Vacancy costs are the economic costs resulting from an unfilled position. These include lost value creation, productivity losses within the team, additional expenses for management and recruiting, external interim solutions, delays in projects, and risks associated with losing customers or quality issues.
Anyone who wants to determine the costs associated with a vacant position should factor these effects into a model. The model is not a substitute for a financial audit. It provides a reliable basis for decision-making regarding prioritization, budgeting, and recruiting capacity.
The Four Cost Categories Associated with a Vacancy
- Loss of value creation: The position does not produce any output, even though there is a need, a budget, and tasks to be performed.
- Team workload: Colleagues take on additional tasks, work more slowly toward their own goals, or accumulate overtime.
- Management Effort: Managers coordinate transitions, prioritize conflicts, and fill operational gaps.
- Recruiting and opportunity costs: Job postings, sourcing, service providers, interview time, and lost candidates all increase the total cost.
Many companies track advertising costs, agency fees, and interview hours. That’s good practice, but it doesn’t go far enough. The most expensive costs often arise where no invoice is received: in lost new business, in delayed product launches, and in the extra workload placed on a team that’s already working at its limit.
How can you determine the cost of a vacant position?
The simplest formula is:
Vacancy Cost = Daily Value Contribution of the Position × Number of Vacancy Days × Role Factor
This formula is simple. It works if you define the inputs clearly. The daily value contribution can be derived from salary, revenue contribution, contribution margin, productivity impact, or a role-based multiplier. The role factor takes into account the extent to which the position contributes to revenue, risk, team performance, or customer loyalty.
Start conservatively. A model that’s too aggressive is rarely convincing. A well-reasoned range will win over Finance, HR, and the business unit. That’s exactly why our vacancy cost calculator uses multiple assumptions rather than a seemingly exact number.
Conservative estimate of salary and non-wage labor costs
For many specialist and staff roles, a conservative starting point based on employer costs is appropriate:
Annual Salary × Employer Cost Factor ÷ Workdays × Days of Vacancy
Here’s an example: A controller position is budgeted at 72,000 euros in annual salary. With an employer cost factor of 1.25, this results in 90,000 euros in annual employer costs. Based on 220 working days, the daily cost is approximately 409 euros. If the position remains vacant for 120 days, this results in conservative vacancy costs of 49,080 euros.
This calculation does not reflect the full extent of the damage. It is suitable for discussions in which you want to use a conservative lower limit. It is rarely sufficient for role-based value creation.
Calculation Based on Value Added
The next step in the calculation asks: What economic contribution would that person have made?
In Sales, you can see this difference right away. An account executive with an annual quota of 800,000 euros doesn’t generate a loss equal to their salary, but rather one equal to the expected contribution margin or revenue contribution. In Customer Success, retention is what counts. In Product and Engineering, speed, technical debt, and revenue milestones are what matter. In Finance, what counts is the quality of management, error prevention, and the ability to close the books.
Assuming that these roles generate revenue systematically leads to an underestimation. Revenue is the price of labor, not necessarily its value contribution.
Sample Calculation: How Much Does an Unfilled Sales Position Cost?
Let’s take a senior sales role at a SaaS company. The base salary is 80,000 euros, and the target compensation is 120,000 euros. The annual quota is 900,000 euros. Internally, the company estimates a 70 percent realistic target achievement rate and a 75 percent gross margin.
The expected annual gross contribution is 472,500 euros. Based on 220 working days, this amounts to approximately 2,148 euros per working day. If the position remains unfilled for 120 days, the calculated shortfall in gross contributions is 257,760 euros. Even if you conservatively estimate only half of that amount, the vacancy still amounts to approximately 129,000 euros.
Now compare this amount to external recruiting costs. In this context, additional sourcing capacity, an interim recruiter, or a focused active-sourcing project doesn’t seem expensive—it seems like a rational decision.
What key figures you need for the calculation
A good calculation doesn’t need 30 variables. Too many assumptions reduce acceptance. In our projects, we work with a small number of transparent inputs.
| Key Metric | Why it is relevant | Typical source within the company |
|---|---|---|
| Projected Annual Salary | Basis for conservative employer costs | Budget, compensation band, HRIS |
| Employer Cost Factor | Takes into account payroll overheads and internal cost logic | Finance, Payroll, Controlling |
| Days of Vacancy | Measures the duration of economic loss | ATS, Department, Workforce Planning |
| Role Factor | Distinguishes between sales roles, key roles, and staff roles | HR, Business Unit, Executive Management |
| Time to Hire | Shows the speed of the process until the contract is accepted | Recruiting Reporting |
| Time to Productivity | Tracks ramp-up after launch | Department, Performance Data |
If this data is missing, start with approximate values. It’s better to have a transparent estimate than to rely on a hunch. It’s important to disclose your assumptions and refine them over time. The cost of a vacant position can still be reasonably estimated even with an incomplete data set, as long as the assumptions are clearly documented.
The biggest calculation error: Estimating the vacancy period too short
When calculating the cost of a vacant position, the duration is often underestimated. Companies expect it to take 60 days because, in theory, the process should be completed in 60 days. The market doesn’t work according to plan.
The IAB Job Vacancy Survey reported approximately 1.03 million job openings nationwide for the third quarter of 2025. Labor demand was thus lower than in the previous year, but job openings remain a key management issue.
When it comes to hard-to-fill roles, the focus shifts. In IT, engineering, finance, sales, or specialized leadership roles, it’s not so much the number of applications that matters, but rather the number of suitable candidates who are ready to make a career move. Bitkom reported approximately 109,000 unfilled IT positions in Germany by 2025. This figure explains why generic campaigns in IT recruiting projects often generate little traction.
The recruitment process doesn’t begin with the job posting
In many companies, the need for a new hire arises before the recruiting process begins. The need arises when an employee resigns, a project is approved, or a team loses its ability to deliver. The job posting often follows weeks later. In between, there are approval processes, profile alignments, budget reviews, and internal discussions.
For a complete calculation, we therefore recommend two values:
Recruiting vacancy: Time from approval to contract acceptance. Business vacancy: Time from actual need to the new hire’s productive contribution.
The second figure is almost always higher. It is more relevant to management.
“Time-to-Hire” Is Not a Sufficient Metric
Time-to-hire measures the speed of the recruiting process. Hiring costs measure economic loss. These two metrics are related, but they answer different questions.
A position can be filled in 45 days and still result in high vacancy costs if the ramp-up takes six months. Conversely, a 90-day search may be economically justifiable if the position contributes little to direct revenue and can be effectively covered internally.
At Kooku, we typically combine these key metrics to create a robust management system:
- Time-to-Approve: How long does approval take?
- Time to Shortlist: When Will Suitable Candidates Be Available?
- Time to Interview: How quickly does the department respond?
- Time to Offer: When Is a Specific Offer Made?
- Offer Acceptance Rate: How often do you close a deal after making an offer?
- Time to Productivity: When will the new employee be fully productive?
If you want to refine your metrics, take a look at our article on the most important recruiting KPIs. Hiring costs are part of this set because they translate recruiting into business terms.
Costs of Unfilled Positions by Role: Sales, IT, Finance, HR
A one-size-fits-all formula for all roles leads to misplaced priorities. A vacant office management position incurs different costs than a vacant VP of Sales role. Both positions can be important, but the economic logic behind them differs.
Sales: Lost Pipeline Instead of Saved Salary
In sales, what matters are quotas, pipeline development, probability of closing, and sales cycle length. An open position doesn’t just hurt at the end of the month. It hurts as soon as new sales calls stop coming in. Especially in B2B SaaS, there’s a delayed effect: a lack of new business in April impacts revenue in September.
When calculating the costs of a vacant sales position, do not use the fixed salary as a basis. Instead, use target compensation, quotas, realistic target achievement rates, margins, and the average sales cycle. For leadership roles in sales, factor in team leverage: forecast quality, coaching, performance management, and deal support.
For specialized sales roles, you can find further information on our page about headhunters for sales professionals and sales executives.
IT and Engineering: Delayed Delivery Costs the Market Window
When it comes to tech roles, many companies focus primarily on team capacity. That’s not enough. The absence of a senior engineering role can delay architectural decisions, slow down code reviews, hinder junior teams, or prolong security risks.
This calculation needs to be tied to a specific project. Which releases are tied to this role? Which customers are waiting? Which internal automations will be delayed? Which technical debts are accumulating? In addition to salary data, we therefore often use sprint goals, roadmap dependencies, and escalation costs.
Finance: Errors, Delays, and Lack of Oversight
Finance vacancies may seem less noticeable, but they can quickly become very costly. Monthly closings, liquidity planning, forecasts, BI reporting, audit preparation, and investor reporting all depend on reliable routines. When a key person is absent, executives have to take on operational tasks. Strategic financial management loses momentum.
When it comes to finance roles, it is not enough to simply evaluate the workload. When determining the costs of a vacant position, risks should also be taken into account: delayed financial closings, poor decisions based on weak data, external consulting costs, and the burden on the CFO level.
For leadership and specialized roles in the finance sector, you’ll find guidance in our offerings for finance headhunting and CFO-related roles.
HR and Talent Acquisition: The Number of Open Positions Is Skyrocketing
A vacant recruiting position has an impact that many companies underestimate. When there is no Talent Acquisition Manager, other hiring processes take longer. One vacancy leads to five slower processes.
The budget should therefore account for open positions in the hiring plan. If a recruiter manages six search projects per month and the position remains open for three months, it’s not just HR services that are missing. Shortlists, interviews, job offers, and new hires are also missing across several departments.
In such situations, companies often turn to on-demand recruiting as a flexible resource because obtaining internal approval for headcount takes too long.
Why Averages Can Be Misleading
Average vacancy costs provide a general guide. They are no substitute for a role-based calculation. StepStone estimated the average vacancy costs in Germany for 2023 at around 49,500 euros. This figure indicates the order of magnitude, not your specific situation.
An open junior marketing position in a stable team incurs different costs than not having a Head of Engineering ahead of a product launch. An average value smooths out precisely the differences that matter most for your decision. Use benchmarks as a plausibility check, but let your internal calculations guide you. You know your pipeline, roadmap, customer risks, and team workload better than any market study. And that’s exactly why a role-specific analysis of the costs of a vacant position provides a better basis for decision-making than any industry figure.
A table for initial prioritization
The following matrix helps sort open positions by economic risk. It is not a substitute for a detailed calculation, but it provides clarity for the hiring plan and budget discussions.
| Roll Type | Typical Cost Driver | Appropriate calculation logic | Priority in the event of a bottleneck |
|---|---|---|---|
| Revenue Roles | Lack of pipeline, closed deals, retention | Ratio × Goal Achievement × Margin × Vacancy Duration | High |
| Key Roles in Tech | Release Delays, Technical Risks, Team Obstacles | Project value, roadmap costs, salary multiplier | High |
| Finance and Controlling | Delayed reporting, mismanagement, external costs | Employer costs plus risk factor | Moderate to high |
| HR and Recruiting | Delays in Filling Other Roles | Impact on the Hiring Plan and Time-to-Hire | High during periods of growth |
| Operations | Process bottlenecks, delivery issues, quality costs | Throughput, defect costs, team workload | Medium to high |
| Staff Roles | Management overhead, delays, service quality | Employer costs plus a moderate multiplier | Context-dependent |
Costs of Unfilled Positions in Small and Medium-Sized Businesses
In small and medium-sized businesses, a vacant position often carries more weight than it does in large corporations. Teams work more closely together. It is less common to have two people filling the same role. A single senior-level position encompasses knowledge, customer history, and responsibility for processes.
For small and medium-sized businesses, we recommend a pragmatic approach:
- Start with the planned annual salary, including employer costs.
- Determine the realistic length of time a business position remains vacant, from the time the need arises until the employee becomes productive.
- Rate the role using a factor between 1.0 and 3.0.
- Include any direct additional costs, such as freelancers, consulting, advertising, or service providers.
- Document qualitative risks separately, rather than artificially converting them into euros.
Management would rather accept five clear assumptions than 18 variables based on a limited data set. In small and medium-sized businesses, determining the cost of a vacant position means, above all, keeping things clear and understandable.
We show what this breakdown looks like compared to the fees charged by a recruiting agency for small and medium-sized businesses on our page about recruiting for small and medium-sized businesses.
What Job Openings Have to Do with Employer Branding
Long-term vacancies send a message. Internally, teams wonder why no one is stepping in to lighten the load. Externally, candidates see job postings that remain online for months. That rarely comes across as appealing. The situation becomes particularly critical when candidates don’t receive feedback for weeks after an interview.
Employer branding doesn’t start with the tagline on the careers page. It starts with the experience of the process. Those who communicate quickly, clearly, and respectfully earn trust. Those who are slow to respond lose qualified candidates to competitors.
If you’d like to evaluate your employer brand from a recruiting perspective, our article on the Employer Branding Score and fill rate provides a helpful in-depth look.
How to Reduce the Costs of Unfilled Positions Without Compromising the Quality of Your Hiring Process
Filling a position quickly only helps if the person is a good fit. Speed without quality shifts costs to the probationary period. Quality without speed means missing out on opportunities. The key lies in managing the process.
Refine the briefing before the search begins
Many processes are delayed by two to three weeks because the requirements remain unclear. Is leadership experience absolutely required? Which tech stacks are mandatory? What industry knowledge really matters? What is the approved salary range?
A good briefing reduces wasted effort. It increases the success rate in sourcing and prevents interviews with candidates who were never realistic prospects.
Check the candidate market before starting your search
An ideal candidate profile is not the same as a market profile. An analysis of the candidate market is particularly worthwhile for specialized roles. It shows how large the addressable market is, what salaries are realistic, which locations are viable, and what factors influence candidates’ decisions.
This analysis also reveals the other side of the equation: How much will it cost if you start with unrealistic requirements?
Using Active Sourcing Strategically
Job postings reach active candidates. In roles with a shortage of candidates, that’s rarely enough. Active sourcing opens up the market of professionals who are passively looking to change jobs. The quality depends on understanding the target audience, timing, and the approach.
At Kooku, we use straightforward communication, clearly state the company’s name, and provide specific role details. This helps reduce mistrust. Candidates are more likely to respond when they understand what the opportunity is about. Learn more on our Active Sourcing Agency page.
Condense the interview process
Four interview stages, two case studies, and a three-week gap between feedback sessions rarely align with the candidate market. A streamlined process does not mean less care. It means clearly defined roles for each interview, fixed decision-making windows, and binding feedback deadlines.
To improve operations, we recommend a six-step candidate journey. A well-designed candidate journey reduces dropouts and helps maintain your hire rate.
Use Weekly Reporting
The costs associated with unfilled positions decrease when teams identify early on where the process is stalling. Too few suitable candidates? A low response rate? Slow responses from the hiring department? Rejections after salary discussions? Each cause requires a different solution.
Our data-driven approach combines sourcing metrics, pipeline status, and process feedback. If you’d like to learn more about this topic, read our article on data-driven recruiting.
When External Recruitment Support Makes Financial Sense
External support is worthwhile if the cost of the vacancy is higher than the cost of the additional recruiting capacity. That sounds obvious, but it’s rarely calculated accurately.
Here’s an example: A vacant engineering position costs, at a conservative estimate, 800 euros per day. An external recruiting sprint shortens the hiring process by 30 days. The avoided cost amounts to 24,000 euros. If the support costs less and improves the quality of candidates, the numbers clearly speak in its favor.
Anyone who understands the cost of a vacant position no longer compares a service provider’s fee based on gut feeling, but rather on the lost revenue that is avoided.
For companies experiencing short-term spikes in workload, interim recruiting or on-demand recruiting is a good option if you need additional capacity without adding permanent headcount.
How Kooku Makes It Easier to Manage Open Positions
We support companies that need to fill critical positions or whose recruiting teams are temporarily understaffed. Our work rarely begins with “Let’s start looking.” It begins with the question: Which role is causing which business pressure, and which recruiting strategy will realistically close the vacancy the fastest?
Our recruiters integrate with client tools, work with weekly KPI reports, and assess early on whether the approach, target market, and process are a good fit. This prevents trial-and-error. This early clarity is especially important for roles in tech, sales, finance, product, HR, marketing, design, and operations.
If you’d like to develop a specific staffing plan based on cost considerations, we’d be happy to discuss your open positions. Schedule an appointment through our page for recruiting consulting and project planning.
I look forward to an exchange on the topic

Your next decision: assess, prioritize, act
A vacant position doesn’t just cost money at some point in the future. It costs money today. The question isn’t whether a vacant position incurs costs, but whether you are aware of those costs and can manage them.
Start with three roles that are noticeably missing within the company. Begin by estimating the costs of the unfilled positions using a conservative lower bound. Add the economic value contribution. Estimate the realistic duration of the vacancy, including the ramp-up period. This will help you determine which search requires priority attention, budget, or additional recruiting capacity.
Looking at the cost of a vacant position doesn’t provide the whole truth. It helps you make a better decision. And that’s exactly what recruiting is all about: not more activity, but more impact per week.

Frequently Asked Questions About the Costs of Unfilled Positions
StepStone estimated the average cost of a vacant position in Germany for 2023 at approximately 49,500 euros per unfilled position. An average figure is not sufficient for your own planning. It makes more sense to use a calculation that takes into account the role, salary, value contribution, vacancy duration, and ramp-up period.
Depending on the role, a vacant position costs anywhere from a few hundred to several thousand euros per day. The cost of a staff position can often be calculated based on salary and employer costs. A sales, IT, or management role requires a value-contribution analysis because revenue, project delays, or team leverage can increase the financial impact.
Vacancy costs are all the economic costs associated with an open position: lost productivity, team overload, management overhead, recruiting costs, project delays, and risks arising from quality or customer issues. Calculating these costs translates the impact of a vacant position into a reliable cost range.
For an initial estimate, use the following formula: daily value contribution of the position × number of days the position is vacant × role factor. For a conservative estimate, use the annual salary plus employer costs. For revenue-generating or key roles, you should use the expected value contribution.
Yes, recruiting costs are part of the overall picture. These include job postings, sourcing, service providers, interview time, and internal coordination. The larger cost is often the lost value contribution. Recruiting costs should therefore never be evaluated in isolation.
The most effective approach involves clear briefings, realistic market analysis, active sourcing, short feedback cycles, and confirmed interview slots. Additional recruiting capacity is worthwhile if it reduces the time to fill a position by more than it costs.
