Cost per Hire: Formula, Benchmarks and What Screening Automation Changes
How to calculate cost per hire: what counts as internal and external cost, a worked example, and the recruiter screening time most teams leave out.
Cost per hire is what you spend to make one hire: your internal recruiting costs plus your external recruiting costs for a period, divided by the number of hires in that period. It is the standard formula, published by SHRM with the American National Standards Institute in 2012 (ANSI/SHRM 06001.2012), and the same one most recruiting dashboards use.
The formula is easy. The hard part is counting honestly, because the biggest cost in most hiring teams, people's time, never arrives as an invoice. This guide covers both buckets, a worked example, why benchmarks disagree, and what automating the first round changes and doesn't.
What is the cost per hire formula?
Cost per hire = (internal recruiting costs + external recruiting costs) ÷ number of hires
All three figures cover the same period, usually a quarter or a year. A few rules keep the number honest:
- Count the costs of the whole period, including roles you worked on but didn't fill. Unfilled searches still cost money, and spreading them over the hires you did make is what the formula intends.
- Count hires as accepted offers in the period, and say whether you include internal moves.
- Keep the same definitions every time. A cost per hire is mostly useful against your own last quarter, and only if both were counted the same way.
What goes into internal costs?
Internal costs are what hiring costs inside your own organization:
- Recruiter time: pay and benefits for the share of their hours spent recruiting. For a dedicated recruiting team, that is most of their cost.
- Hiring manager and interviewer time: hours spent reviewing applications, interviewing and debating candidates, at each person's loaded hourly rate.
- Referral bonuses paid to employees.
- Recruiting technology: the share of your applicant tracking system, scheduling tools and other software that goes to hiring.
- Overhead: the share of office, equipment and management cost that goes to the recruiting function, if you allocate it.
What goes into external costs?
External costs are payments to outside parties:
- Job board and advertising fees
- Agency and executive search fees
- Background and reference checks
- Assessments and skills tests
- Career fairs, events and campus visits
- Candidate travel and relocation, if you pay it
- Sign-on bonuses, if your organization counts them here
A worked example
A team made 30 hires in a quarter. The figures below are illustrative, not benchmarks:
| Cost | Amount |
|---|---|
| Recruiter time (two recruiters, the share of their quarter spent recruiting) | $42,000 |
| Hiring manager and interviewer time | $18,000 |
| Referral bonuses | $6,000 |
| Share of recruiting software | $4,500 |
| Internal total | $70,500 |
| Job boards and advertising | $12,000 |
| One agency placement | $18,000 |
| Background checks | $1,500 |
| External total | $31,500 |
Cost per hire = ($70,500 + $31,500) ÷ 30 = $3,400.
Notice where the money is. Internal time is more than twice the external spend, and most teams that only count invoices would report a cost per hire of about $1,050, less than a third of the real figure.
What are typical cost-per-hire benchmarks?
Published averages vary so much that quoting one number would mislead you. Figures differ by year, by whether the role is executive or not, by whether the source reports an average or a median, and by what each survey counted. Before using any outside benchmark, check three things: which costs it included, whether it reports a mean or a median, and which roles it covers.
The comparison that pays off is your own: cost per hire by role family, quarter on quarter, counted the same way each time. If it rises, the breakdown shows which bucket moved.
What is the hidden cost of first-round screens?
Recruiter time on first-round screens rarely appears as its own line, yet in high-volume hiring it can be the largest single internal cost. Work it out:
Screening hours = candidates screened × minutes per screen ÷ 60
Count the whole screen: scheduling it, the call itself, and writing it up. A 15-minute call often takes 25 to 30 minutes once the emails and notes are included.
Screening cost = screening hours × loaded hourly rate
For example, a recruiter screening 40 candidates a week at 30 minutes each spends 20 hours a week on screens, half their working week. At a loaded rate of $65 an hour, that is $1,300 a week, or roughly $5,600 a month, before a single hiring manager interview. The free screening cost calculator runs these numbers with your own inputs.
That time also stretches time to hire: a recruiter booked solid with screens can't respond to new applicants quickly, and slow responses cost candidates.
Which recruiter productivity metrics go with cost per hire?
Cost per hire tells you what hiring costs; a few companion metrics tell you why:
- Time to first screen: days from application to the first conversation. A long wait usually means the first round is the bottleneck.
- Interviews per hire: how many interviews it takes to make one hire. Gem's 2025 benchmarks report this rose from 14 to 20 between 2021 and 2024 (Gem, a vendor report). Our guide to the interview-to-hire ratio covers how to count it.
- Pass-through rate by stage: the share of candidates who move from each stage to the next. A stage that passes almost everyone isn't filtering; one that passes almost no one may be screening on the wrong things.
- Hires per recruiter: useful within one team over time, misleading across teams with different role mixes.
- Offer acceptance rate: a late "no" wastes everything spent before it.
What does automating the first round change?
Automating first-round screens changes the internal side of the formula. When candidates take a structured AI interview on their own schedule, the scheduling disappears and the recruiter's time per candidate becomes review time: reading a scorecard and listening to the parts of the recording that matter. Recruiter hours per hire fall, and the first screen happens sooner.
It doesn't change the external side: job boards, agency fees, background checks and offers cost the same. It doesn't remove the hiring manager's interviews, and it doesn't make decisions. Someone still has to read the evidence and choose, and the time that takes belongs in the formula too.
DIO, Dio's AI interviewer, is built for that first round. Candidates open a link and take a structured voice interview in the browser, usually in about 15 minutes, and the team gets a recording, a transcript and a scorecard in which each competency score quotes the candidate's own words. A person on the team makes every decision. If you are comparing tools, the guide to choosing AI interview software lists the questions to ask.
