Worked Example: Cost Per Hire Calculation for a Growing Tech Startup

Cost per hire (CPH) is the foundational metric for measuring recruiting efficiency. This walkthrough calculates CPH for a 50-person tech startup using the cost per hire calculator and compares it to the SHRM industry benchmark.

The Scenario

TechCo (50 employees, $5M revenue) hired 12 people in the past year. Their recruiting spend:

Cost Category	Amount
Internal HR/recruiter salary (0.5 FTE)	$50,000
LinkedIn Recruiter seat	$10,000
Indeed job board ads	$4,000
Greenhouse ATS subscription	$9,000
Background checks (12 × $75)	$900
Skills assessment platform	$2,500
Referral bonuses paid (4 × $2,000)	$8,000
Agency fee for 1 senior role (20% of $130k)	$26,000
Candidate travel reimbursement	$1,500
Sign-on bonuses (3 × $5,000)	$15,000
New hire welcome package	$600

Let's calculate TechCo's cost per hire.

Step 1: Calculate Total Recruiting Cost

Add all categories:

$50,000 + $10,000 + $4,000 + $9,000 + $900 + $2,500 + $8,000 + $26,000 + $1,500 + $15,000 + $600 = $128,100 total recruiting cost

Step 2: Calculate Cost Per Hire

Cost per hire = Total recruiting cost / Number of hires Cost per hire = $128,100 / 12 = $10,675 per hire

Step 3: Compare to SHRM Benchmark

SHRM's 2024 Talent Acquisition Benchmark Report cites the average US cost per hire as $4,700.

TechCo's CPH is 2.27x the benchmark — significantly above average. Let's investigate why.

Step 4: Break Down by Cost Category

Category	Amount	% of Total
Internal HR salary	$50,000	39.0%
Agency fee (1 senior role)	$26,000	20.3%
Sign-on bonuses	$15,000	11.7%
Referral bonuses	$8,000	6.2%
Greenhouse ATS	$9,000	7.0%
LinkedIn Recruiter	$10,000	7.8%
Indeed ads	$4,000	3.1%
Skills assessment	$2,500	2.0%
Candidate travel	$1,500	1.2%
Background checks	$900	0.7%
Welcome package	$600	0.5%
Total	$128,100	100%

Step 5: Identify Cost Drivers

Three categories drive 71% of total cost:

1. Internal HR salary ($50k / 39%) — hard to reduce without slowing hiring
2. Agency fee ($26k / 20%) — avoidable for non-senior roles
3. Sign-on bonuses ($15k / 12%) — necessary in competitive tech market

Step 6: Calculate Cost Per Hire by Channel

Different hiring channels have very different costs:

Channel	Hires	Total Cost	Cost Per Hire
Referrals	4	$8,000 (bonus only)	$2,000
Direct application (LinkedIn/Indeed)	5	$24,000 (ads + HR time)	$4,800
Agency placement	1	$26,000	$26,000
Internal promotion	2	$0 incremental	$0
Total	12	$128,100	$10,675 blended

Referrals are 13x cheaper than agency hires — this is the single biggest lever for reducing CPH.

Step 7: Calculate Indirect Costs (Manager Time)

The SHRM benchmark includes only direct costs. Let's add indirect costs (manager interview time):

• Average manager time per hire: 8 hours (resume review, 3 interviews, debrief)
• Average manager hourly cost: $75/hour (loaded)
• 12 hires × 8 hours × $75 = $7,200 indirect cost

Adding this to the direct cost:

Total CPH with indirect = ($128,100 + $7,200) / 12 = $11,275 per hire

Indirect costs add only 5.6% here, but for roles requiring more interviews (executive searches), indirect can be 30%+ of total.

Step 8: Optimization Scenarios

Scenario A: Reduce Agency Dependency

If TechCo replaces the $26k agency hire with a referral ($2k bonus):

New total cost: $128,100 − $26,000 + $2,000 = $104,100 New CPH: $104,100 / 12 = $8,675 (19% reduction)

Scenario B: Build Referral Program

If TechCo doubles referral hires (4 → 8) by raising bonus to $3,000:

New referral cost: 8 × $3,000 = $24,000 New total cost: $128,100 − $8,000 + $24,000 − $4,000 (Indeed savings) = $140,100 Wait — that's MORE cost. Let me recalculate properly.

If 4 more hires come from referrals instead of paid sources:

• Saved: $4,000 Indeed ads (assuming referrals replace them)
• Added: 4 × $3,000 = $12,000 additional referral bonuses
• New total: $128,100 + $12,000 − $4,000 = $136,100
• New CPH: $136,100 / 12 = $11,342

Hmm, that's worse! The issue is that referral bonuses are too generous. Let's try $1,500:

• Saved: $4,000 Indeed
• Added: 4 × $1,500 = $6,000
• New total: $128,100 + $6,000 − $4,000 = $130,100
• New CPH: $130,100 / 12 = $10,842

Still worse. The key is that referrals replace AGENCY hires, not paid job board hires. Let me redo:

If 4 more referrals replace 4 direct applications (each costing ~$4,800):

• Saved: 4 × $4,800 = $19,200
• Added: 4 × $2,000 = $8,000
• New total: $128,100 − $19,200 + $8,000 = $116,900
• New CPH: $116,900 / 12 = $9,742 (9% reduction)

Plus referred hires have 35% higher 2-year retention — compounding savings on turnover cost.

Step 9: Try It Yourself

Enter TechCo's numbers into the cost per hire calculator:

• Internal costs: $50,000 (HR salary) + $9,000 (ATS) = $59,000
• External costs: $26,000 (agency) + $1,500 (travel) = $27,500
• Job boards: $10,000 (LinkedIn) + $4,000 (Indeed) = $14,000
• Background checks: $900
• Other: $2,500 (skills) + $8,000 (referral bonuses) + $15,000 (sign-on) + $600 (welcome) = $26,100
• Number of hires: 12

You should see $10,675 cost per hire.

Step 10: Calculate Time-to-Fill

Time-to-fill is the other key recruiting metric. TechCo's average time-to-fill was 55 days — above the SHRM benchmark of 42 days.

The cost of a vacancy (lost productivity while the role sits unfilled):

• Average role value: $150,000/year revenue per employee
• 55 days at $150k/year = $22,602 in lost productivity per hire
• 12 hires × $22,602 = $271,227 in vacancy cost

Adding this to direct recruiting cost:

Total recruiting + vacancy cost = $128,100 + $271,227 = $399,327 Total cost per hire (with vacancy) = $399,327 / 12 = $33,277

The vacancy cost dwarfs the recruiting cost — slow hiring is more expensive than expensive hiring.

Common Cost Per Hire Mistakes

1. Excluding sign-on and referral bonuses — these are direct recruiting costs
2. Not allocating HR salary correctly — a 0.5 FTE recruiter costs $50k+ loaded
3. Forgetting ATS subscription — annual SaaS costs add up
4. Ignoring indirect costs — manager interview time is real cost
5. Not comparing to industry benchmark — $4,700 SHRM average is the comparison point

Industry CPH Benchmarks

Industry	Cost Per Hire	Time-to-Fill
Retail / QSR	$300-$800	14-21 days
Manufacturing	$3,000-$5,000	35-45 days
Healthcare	$4,000-$7,000	50-70 days
Technology	$5,000-$10,000	45-60 days
Financial services	$8,000-$15,000	50-70 days
Executive search	$20,000-$50,000+	90-120 days

TechCo at $10,675 is at the high end of technology benchmarks — driven by the $26k agency fee.

Key Takeaways

• Referrals are the cheapest source of hires — typically 50-70% cheaper than agency or job board
• Sign-on bonuses count as recruiting cost — don't exclude them from CPH
• Slow hiring is more expensive than expensive hiring — vacancy cost often exceeds recruiting cost
• Track CPH by channel — agency, referral, direct, internal promotion all have different economics
• Build the referral program before reducing agency spend — otherwise you'll just slow hiring
