Most companies budget for engineering hiring like they're buying office supplies: a line item to minimize. Then they wonder why every hire takes four months and half the offers get rejected.
After analyzing hiring data from 200+ companies, I've found that the average engineering hire actually costs $28,400—but that number hides massive variation. A seed-stage startup hiring their first engineer faces completely different economics than a Series C company scaling to 100 engineers.
Let me break down what you should actually budget, based on real data.
The True Cost Components
Most hiring budgets only capture direct costs. Here's the full picture:
| Cost Category | % of Total | What's Included |
|---|---|---|
| Direct Costs | 35-45% | Recruiter fees, job posts, tools, assessments |
| Interview Time | 25-35% | Engineering hours spent interviewing |
| Vacancy Cost | 20-30% | Lost productivity while role is open |
| Onboarding | 5-10% | Training, ramp-up, reduced productivity |
The math that surprises everyone: A senior engineer role open for 8 weeks costs roughly $15,000-25,000 in lost productivity alone—before you've spent a dime on recruiting.
Budget Benchmarks by Company Stage
Seed Stage (1-10 engineers)
Annual hiring budget: $50,000-100,000 Cost per hire: $15,000-25,000
At this stage, founder time is your biggest cost. Expect to spend:
| Item | Annual Cost |
|---|---|
| Job boards (LinkedIn, Wellfound) | $5,000-8,000 |
| One sourcing tool | $6,000-12,000 |
| Part-time coordinator | $25,000-35,000 |
| Contingency for agency hire | $20,000-40,000 |
Critical insight: Don't hire a full-time recruiter until you're making 15+ hires per year. The economics don't work below that threshold.
Series A (10-50 engineers)
Annual hiring budget: $200,000-400,000 Cost per hire: $20,000-30,000
This is where you professionalize:
| Item | Annual Cost |
|---|---|
| Full-time recruiter (1 FTE) | $90,000-130,000 |
| Recruiting stack (ATS, sourcing, scheduling) | $25,000-40,000 |
| Employer branding | $15,000-30,000 |
| Interview training | $5,000-15,000 |
| Agency fees (20% of hires) | $40,000-80,000 |
Rule of thumb: One recruiter can handle 20-30 engineering hires per year. If you're growing faster, add headcount before you burn out your team.
Series B+ (50-200 engineers)
Annual hiring budget: $600,000-1,500,000 Cost per hire: $25,000-40,000
At scale, you need infrastructure:
| Item | Annual Cost |
|---|---|
| Recruiting team (3-6 FTEs) | $350,000-700,000 |
| Full recruiting stack | $60,000-120,000 |
| Employer branding & events | $80,000-150,000 |
| University recruiting | $40,000-80,000 |
| Referral bonuses | $100,000-200,000 |
| Executive search (leadership roles) | $100,000-250,000 |
Where Companies Waste Money
After auditing dozens of hiring budgets, I see the same mistakes repeatedly:
Mistake #1: Over-investing in job boards
Typical waste: $15,000-30,000/year
Job boards generate high volume but low quality for engineering roles. The best engineers aren't browsing Indeed—they're being sourced directly or coming through referrals.
Better allocation: Shift 60% of job board budget to referral bonuses. Data shows referral hires perform better, stay longer, and close faster[^1].
Mistake #2: No budget for interview training
Hidden cost: $50,000-150,000 per bad hire
Untrained interviewers make inconsistent, biased decisions. A single bad hire costs 6-9 months of salary when you factor in recruiting, onboarding, management time, and eventual separation[^2].
What to budget: $500-1,000 per interviewer annually for training and calibration.
Mistake #3: Using agencies as primary strategy
Excess cost: $20,000-40,000 per hire
Agencies charge 20-25% of first-year salary. For a $200,000 engineer, that's $40,000-50,000. You could hire a full-time recruiter for the cost of 2-3 agency placements.
When agencies make sense:
- Urgent backfill (someone quit, project at risk)
- Specialized roles (ML, security, niche technologies)
- Executive search
When they don't: Standard engineering hiring that you do repeatedly.
Calculating Your Budget
Here's the formula I use with clients:
Annual Budget = (Planned Hires × Base Cost) + (Recruiting Team × $110,000) + Infrastructure
Base cost by level:
| Level | Base Cost per Hire |
|---|---|
| Junior | $12,000-18,000 |
| Mid-level | $18,000-25,000 |
| Senior | $25,000-35,000 |
| Staff+ | $35,000-50,000 |
| Director+ | $60,000-100,000 |
Example: Company planning 30 hires (10 senior, 15 mid, 5 junior):
- Senior: 10 × $30,000 = $300,000
- Mid: 15 × $22,000 = $330,000
- Junior: 5 × $15,000 = $75,000
- 2 recruiters: $220,000
- Infrastructure: $50,000
- Total: $975,000 (~$32,500 per hire)
Metrics to Track
Don't just set a budget—measure whether it's working:
| Metric | Target | Red Flag |
|---|---|---|
| Cost per hire | $25,000-35,000 (senior) | >$50,000 |
| Time to fill | 45-60 days | >90 days |
| Offer acceptance rate | 75-85% | <60% |
| Quality of hire (6mo) | 90%+ meeting expectations | <80% |
| Recruiter capacity | 25-30 hires/year | <15 hires/year |
The ROI Argument
When finance pushes back on hiring budget, here's the math:
A strong senior engineer generates $500,000-1,000,000 in annual value (salary + multiplier effect on team + revenue impact)[^3]. Spending an extra $10,000 to find the right person—instead of settling for whoever's available—is always worth it.
The real question isn't "How do we spend less on hiring?"
It's "How do we spend enough to get the people who will 10x their cost?"
