How to Reduce Cost-per-Hire with Automation and Assessments

The average cost-per-hire is €4,000-€7,000. With smart automation and assessments, you can halve that. Here's how.

The cost-per-hire formula

Cost-per-hire is one of the most widely used metrics in recruitment, and simultaneously one of the most misleading. The standard formula is:

Cost-per-hire = (internal costs + external costs) / number of hires

The average cost-per-hire in the Netherlands is between €4,000 and €7,000 for standard positions. For specialized or senior positions, it can rise to €15,000-€25,000. And if you engage an external recruitment agency, you're easily looking at €10,000-€20,000 per placement.

But this formula doesn't tell the full story. It misses two crucial elements:

1. The quality of the hire, a cheap hire who leaves after 6 months is ultimately far more expensive

2. Hidden internal costs, the hours of hiring managers and team members that rarely get counted

In this article, we show how to structurally reduce cost-per-hire without sacrificing quality, and how with the right investments, you can actually make better hires at lower costs.

Where does the money go?

To reduce cost-per-hire, you first need to understand where the money goes. Costs break down into two categories:

External costs

  • Job board ads: €500-€2,000 per vacancy on Indeed, LinkedIn, or industry-specific boards. With multiple boards and sponsored listings, this quickly rises to €3,000-€5,000 per vacancy
  • Recruitment agency fees: 15-25% of annual salary. For a €60,000 position, that's €9,000-€15,000, the largest external cost item
  • Assessment tools: €200-€500 per candidate with [generic providers](/artikelen/generic-assessments-dont-work). At 10-20 candidates per vacancy, that's €2,000-€10,000
  • Background checks: €50-€200 per candidate
  • Employer branding: career page, content creation, events
  • Internal costs (often underestimated)

  • Recruiter hours: average 30 hours per hire, of which 60-70% goes to screening
  • Hiring manager time: 10-15 hours per hire on briefings, interviews, and decision-making
  • Team interview time: 5-10 hours per hire, multiple team members are involved
  • Administration: contracts, onboarding documents, IT requests
  • Onboarding: 40-80 hours of guidance from colleagues in the first weeks
  • At an internal hourly rate of €75 for a recruiter and €100 for a hiring manager, internal costs already reach €4,000-€6,000 per hire, excluding external costs.

    The hidden money wasters

    Additionally, there are costs almost nobody counts:

  • Candidate drop-off: you invest in sourcing and screening, but 40-60% of candidates drop out due to [poor candidate experience](/artikelen/high-converting-job-pages) or slow processes
  • Re-hiring: when a hire fails, you start over. Re-hiring costs are rarely attributed to the original hire
  • Tooling overlap: the average recruitment department uses 4-7 separate tools that partially overlap
  • The five levers for lower cost-per-hire

    Lever 1: automate screening (biggest impact)

    Most recruiter time goes to screening: reading CVs, phone screening, conducting first interviews. This is repetitive, time-consuming, and inconsistent work.

    With AI, you automate the heavy lifting:

  • [AI CV screening](/artikelen/ai-replacing-cv-screening): automatic parsing, skills matching, and ranking. Saves 10-15 hours per vacancy on manual CV reading
  • Pre-assessments: candidates are automatically tested on relevant competencies. 60-70% are automatically filtered, so recruiters only see the best candidates
  • [AI pre-interviews](/artikelen/ai-pre-interviews-future): replaces phone screening calls. Saves 15-25 hours per vacancy on phone calls
  • Total savings: 60-80% of screening time, which translates to 15-25 hours per vacancy. At an internal hourly rate of €75, that's €1,125-€1,875 per vacancy.

    Lever 2: better assessments = fewer bad hires

    This is the lever most often overlooked. Every bad hire costs €50,000-€150,000. If you improve hire quality, you save multiples of the assessment investment.

    Calculation example at 100 hires per year:

    ScenarioFailure rateBad hiresCost of bad hires

    |----------|-------------|-----------|-------------------|

    Without assessments20%20€2,000,000 With generic assessments15%15€1,500,000 With [custom assessments](/artikelen/valid-reliable-assessment)8-10%8-10€800,000-€1,000,000

    The difference between generic assessments and custom assessments is €500,000-€700,000 per year, a return that justifies any investment in your own system.

    Lever 3: increase job page conversion

    An average job page has a conversion rate of 8-12% (visitors who actually apply). With an optimized job page, you can increase that to 30-50%.

    What does this mean for cost-per-hire?

  • You need less job board spend to generate the same number of applicants
  • At a spend of €2,000 per vacancy and a doubling of conversion, you effectively save €1,000 per vacancy
  • Bonus: a better candidate experience leads to less drop-off later in the process
  • Lever 4: reduce dependency on recruitment agencies

    Recruitment agencies are the most expensive way to hire. At a fee of 20% on a €60,000 salary, you pay €12,000 per placement. If 30% of your hires go through agencies (at 100 hires = 30 placements), that's €360,000 per year.

    With your own hiring system, you can drastically reduce that dependency:

  • Better direct sourcing through automated screening and assessments
  • Higher conversion on your own job pages
  • Faster processes so candidates don't drop out
  • Better employer branding through a professional candidate experience
  • A reduction of agency dependency from 30% to 10% saves: 20 placements x €12,000 = €240,000 per year.

    Lever 5: own system vs. SaaS stack

    The average recruitment department uses a fragmented stack:

    ToolMonthly cost

    |------|-------------|

    ATS (Greenhouse, Lever, etc.)€500-€2,000 Assessment tool (TestGorilla, Harver)€200-€500 Scheduling tool€100-€200 CRM/sourcing tool€200-€500 Video interview tool€100-€300 Analytics/reporting€100-€300 Total€1,200-€3,800/month

    That's €14,400-€45,600 per year on separate tools that don't work together optimally. With your own integrated system:

  • One-time investment instead of ongoing licenses
  • Better integration, data flows seamlessly between components
  • No vendor lock-in, you [own your data](/artikelen/own-your-hiring-data)
  • Break-even typically at 12-18 months
  • The full picture: halving cost-per-hire

    Let's add everything up for a company making 100 hires per year:

    LeverAnnual savings

    |-------|--------------|

    Screening automation€112,500-€187,500 Better assessments (fewer bad hires)€500,000-€700,000 Higher job page conversion€50,000-€100,000 Fewer recruitment agencies€120,000-€240,000 Own system vs. SaaS stack€14,400-€45,600 Total€796,900-€1,273,100

    Even with conservative calculations, you can reduce cost-per-hire from €5,000-€7,000 to €2,000-€3,000, a halving that directly translates to the bottom line.

    Implementation path: where to start?

    You don't have to do everything at once. The most effective path:

    Phase 1: Quick wins (month 1-2)

  • Optimize your [job pages](/artikelen/high-converting-job-pages) for higher conversion
  • Implement basic pre-assessments to automate screening
  • Analyze your current tooling stack for overlap and costs
  • Phase 2: AI screening (month 2-4)

  • Implement [AI CV screening](/artikelen/ai-replacing-cv-screening) for automatic ranking
  • Introduce [AI pre-interviews](/artikelen/ai-pre-interviews-future) as a replacement for phone screening
  • Start collecting data for [continuous validation](/artikelen/continuous-validation-hiring)
  • Phase 3: Own system (month 4-6)

  • Migrate to an [integrated hiring platform](/ai-hiring-system)
  • Build company-specific assessment models
  • Reduce dependency on external tools and agencies
  • Key takeaways

    Reducing cost-per-hire isn't about cutting quality. It's about smarter investing in your recruitment process:

  • Automate the repetitive work that costs recruiters hours
  • Improve hire quality with [validated assessments](/artikelen/valid-reliable-assessment), every avoided bad hire saves €50,000-€150,000
  • Increase conversion on your job pages to get more from your sourcing budget
  • Reduce agency dependency through a better in-house recruitment process
  • Consolidate your tooling into one integrated system
  • The companies that most effectively reduce their cost-per-hire aren't the ones cutting corners. They're the ones investing in a system that pays for itself.
