What it includes
Cost of hire covers direct costs (advertising, agency fees, assessment tools, recruiter salaries) and indirect costs (interviewer time, admin overhead, lost productivity from vacant roles, and failed hires).
Common formula: (Internal Costs + External Costs) / Number of Hires
Useful as a per-hire average. But it underestimates the true cost because it typically excludes the most expensive component: hiring the wrong person.
Visible costs vs hidden costs
Most calculations focus on what's easy to measure.
Visible: Recruiter time, job ads, sourcing tools, agency fees (15–25% of salary), assessment platforms, interview time. These are real and significant. But they're not where the real money is.
Hidden: Failed hires (~30% of first-year salary per mis-hire). Tech stack fragmentation (separate tools that don't connect). Vacancy costs (lost productivity every day a role stays open). Disrupted teams, consumed management time, repeated hiring cycles.
When you include failed hires, a typical 100-hire organisation spends around €800,000 per year on hiring. Most of that is preventable.
The organisations with the lowest effective cost aren't the ones spending the least on recruitment. They're the ones making fewer bad hires.
Why it matters more than most teams realise
Cost of hire is often treated as an operational metric. Something finance cares about but TA reports reluctantly. That misses the point.
It's the metric that connects hiring quality to business impact. Reduce failed hires, and you save multiples of what you spend on better tools. Consolidate your tech stack, and you gain connected data. Reduce time to hire, and you cut vacancy costs.
How to reduce it
Reduce bad hires. The single largest lever. Every mis-hire avoided saves €18,000–35,000+ in direct costs. Structured hiring can roughly double the number of high performers per cohort.
Reduce agency dependency. Strong internal assessment capabilities mean fewer roles need external recruiters. When agencies are needed, structured criteria make their briefs sharper.
Consolidate your tech stack. A typical stack (ATS €40k + assessments €25k + sourcing €20k = €85k) can be replaced by one integrated system.
Cut admin time per hire. Automation can reduce operational time from ~20 hours to ~8 hours per hire.
How to track cost of hire (and build the business case)
Most TA teams report cost per hire as a flat number. That's necessary but not enough. Here's how to make it useful for leadership:
True cost per hire. Include failed hires, vacancy costs, and admin overhead. Not just the line items. The flat formula (internal + external / hires) underestimates by 40–60% for most organisations.
Cost by channel. Which sourcing channels produce hires at the lowest effective cost? Don't just track cost per application. Track cost per successful hire by channel. Agency-sourced hires may cost more upfront but save time. Direct applicants may be cheap but have higher attrition.
Cost of a bad hire. This is the number that moves leadership. ~30% of first-year salary per mis-hire. For a 100-hire organisation with a 15% failure rate, that's €525,000 per year in preventable waste. Track this explicitly.
ROI of structured hiring. The before-and-after that finance needs. Show the full picture:
For 100 hires per year:
Without structured hiring: Manual coordination €70k + agencies €120k + 15 failed hires €525k + tech stack €85k = ~€800k
With Alva: Reduced admin €28k + fewer agencies €60k + 8 failed hires €280k + Alva platform €95k = ~€463k
Net saving: €337k. ROI: 255% within year one.
The largest saving doesn't come from cheaper tools. It comes from making fewer bad hires. That's the slide that gets budget approval.
One of three hiring fundamentals
Cost of hire connects directly to time to hire (every open day costs money) and quality of hire (bad hires are the most expensive line item in any TA budget).
