What Does It Really Cost to Hire Someone? (Most Organisations Are Wrong by a Factor of Two)
Most organisations think they know what it costs to hire someone. Most of them are wrong by a factor of two or three — and the gap is where the real waste lives.
Ask most HR Directors or heads of talent what their cost-per-hire is and they’ll give you a number. Usually it’s a figure based on what they paid to job boards, or the agency fee they invoiced last quarter. It’s not wrong exactly — but it’s incomplete. And incomplete cost-per-hire data leads to decisions that look sensible on paper and are quietly expensive in practice.
Why the Standard Calculation Falls Short
The most common approach to cost-per-hire is to take your external recruitment spend — job board fees, agency commissions, advertising costs — and divide it by the number of hires. The problem is that external spend is only one part of what hiring actually costs. It ignores the internal costs entirely — and in high-volume hiring organisations, those internal costs are often larger than the external ones.
When you only measure what you invoice for, you optimise for invoice value. The actual cost of filling a role — the full operational load it places on your organisation — stays invisible.
The True Cost-Per-Hire Formula
A complete cost-per-hire calculation has four components. All four need to be measured before you have a number worth making decisions from.
1. External Spend
Job board fees, agency commissions, advertising costs, LinkedIn Recruiter licences and any third-party cost directly associated with sourcing candidates. Most organisations track this. The issue is attribution — they know what they spent, but not which hires it produced.
2. Internal Time Cost
Every hour a member of your team spends on recruitment has a cost. To calculate: take the fully-loaded hourly cost of every person involved in a hire, multiply by the hours spent, and sum the total.
3. Vacancy Cost
Every day a role sits unfilled has an operational cost. Take the day rate of the role and multiply by the number of days the vacancy was open.
4. Onboarding and Ramp Cost
The period between a new hire’s start date and the point at which they’re fully productive. For most roles this is 4–12 weeks. For specialist or regulated roles the deficit is more significant — and should be counted in any honest cost calculation.
The Structural Problem Underneath the Number
Here’s the uncomfortable truth this exercise usually reveals: most recruitment marketing inefficiency isn’t in the advertising — it’s in the system around it. The vacancy duration is long not because there aren’t enough candidates, but because screening workflows are manual and slow. The cost-per-hire is high not because advertising is expensive, but because the same spend is producing fewer qualified applicants than it should.
These are structural problems. They require structural solutions — not more spend on the same channels that are already underperforming. A recruitment marketing audit maps exactly where your system is losing money — which channels are underperforming, where your spend is going without return, and what the 90-day path to fixing it looks like.
