Cost Per Hire for Small Business: How to Calculate It
Ask a small-business owner what their last hire cost and you'll usually hear the price of a job board listing. That's the smallest part of the bill. The real cost includes hours of screening, phone calls, and interviews by people whose time is worth a lot more than an ad — often the owner's own. Knowing the real number tells you which part of hiring to fix first.
The standard formula
The widely used cost-per-hire standard, developed by SHRM and ANSI, is:
Cost per hire = (external costs + internal costs) ÷ total number of hires
For a small business making a few hires a year, it's often more useful to calculate cost for each role individually, since one difficult hire can distort an average across only three or four.
External costs: what you pay outside vendors
- Job board postings and sponsored listings
- Recruiter or agency fees
- Screening and interviewing software
- Background checks and drug tests
- Assessment or skills-testing tools
- Candidate travel, if you pay for it
- Signing bonuses and relocation
Internal costs: what your own time costs
This is the part most small businesses leave out. Estimate hours for each step, then multiply by a loaded hourly rate (pay plus a reasonable estimate for payroll taxes and benefits) for each person involved:
- Writing and posting the job
- Reading and sorting applications
- Phone screens
- Interviews, including prep and scoring
- Reference checks
- Making the offer and negotiating
- Referral bonuses paid to employees
A worked example
Say an owner valued at $75 an hour hires a customer service representative. The owner spends 6 hours screening 120 applications, 3 hours on 12 phone screens, 5 hours on four interviews including prep, and 1 hour on references and the offer: 15 hours, or $1,125 in time. An office manager valued at $35 an hour joins two interviews for 2 hours: $70. A job board listing costs $300 and a background check $50.
Total: $1,125 + $70 + $300 + $50 = $1,545 for one hire. The ad is under 20% of it. These are illustrative numbers — plug in your own — but the pattern holds for most small businesses: the owner's time dominates.
What benchmarks say
SHRM's 2025 benchmarking data, released in October 2025, puts average cost per hire at $5,475 for nonexecutive roles and $35,879 for executive roles. SHRM also reported that screening and interviewing each average 8 to 9 days of the hiring process. Treat these as context rather than a target: SHRM's data reflects organizations of all sizes, including large employers with recruiting teams and agency spend that most small businesses don't have.
What cost per hire leaves out
Cost per hire measures what it took to fill the seat, not whether you filled it well. A cheap hire who leaves in three months is far more expensive than a slightly costlier one who stays. Two other costs are worth tracking alongside it:
- Vacancy cost: the work that doesn't get done, or gets done by an overloaded team, while the role is open.
- Mis-hire cost: the cost of replacing someone who didn't work out, which we cover in the real cost of a bad hire.
Count the costs people forget
A few items rarely make it into small-business estimates but belong there:
- Re-posting. If a listing expired and you paid to run it again, both postings count.
- Interviews that went nowhere. Time spent on candidates who dropped out or weren't a fit is still part of the cost of the hire you made.
- Failed offers. If your first choice declined and you restarted, the whole first round counts.
- Covering the work. Overtime paid to other staff while the seat is empty is a vacancy cost, worth tracking separately.
Track it without an HR system
You don't need special software to know your cost per hire. A simple spreadsheet with one row per role works. Record:
- The role, date posted, and date the offer was accepted (that gives you time to fill).
- Every external cost, with the vendor.
- Rough hours spent by each person at each stage, logged weekly while the search is open. Estimates are fine; they don't need to be exact.
- Number of applicants, phone screens, and interviews.
- Whether the hire was still with you at 90 days and at one year.
After three or four hires, patterns show up. You might find that one job board produces most of your hires and another produces only noise, or that one role always takes twice as long because the requirements are unrealistic. The last column matters most: a search that was cheap but produced someone who left in two months wasn't cheap.
Where small businesses can lower it
- Fix the job post. Clear requirements and pay range mean fewer unqualified applicants to sort.
- Standardize screening. A written must-have list cuts screening hours sharply.
- Shorten the funnel. Fewer, better-chosen interviews cost less than many loose ones.
- Lean on referrals. Employee referrals often bring candidates who already understand the job.
- Automate the front of the process. Screening and first-round interviews are where owner hours pile up.
Where ReqGenius fits in the math
ReqGenius takes on the screening and first-round interview hours: it screens every applicant against the job (resume filtering is free), AI-interviews the best candidates, and delivers a ranked shortlist with evidence. A role costs $249 for 45 days, or $299 a month for up to three roles at once. You still make the hiring decision. Compare that against your own internal-cost estimate on the pricing page.
