What Is Cost Per Hire?
Cost per hire measures the total investment in recruiting a new employee. Learn how to calculate it and benchmark it against your industry.
Key Takeaways
- Cost per hire = total recruiting costs divided by number of hires in the period
- Internal costs (HR time, interview time) are as significant as external costs (agency fees, job boards)
- Referred candidates consistently produce the lowest cost per hire
- Reducing cost per hire through employer brand is more sustainable than cutting job board spend
What cost per hire is
Cost per hire is the total cost your organisation incurs to recruit and onboard a new employee, divided by the number of hires in a defined period. It is one of the foundational HR metrics because recruiting is one of the most significant and often underestimated people costs a business incurs. Understanding it allows you to budget accurately for growth, identify inefficiencies in your recruiting process, and evaluate the ROI of different sourcing channels.
What to include in the calculation
Total recruiting costs include both external and internal costs. External costs: agency fees (typically 15-25% of starting salary), job board and LinkedIn advertising spend, background check fees, and assessments. Internal costs: HR team time for job posting, screening, coordination, and offer management; hiring manager and interview panel time; signing bonuses or relocation packages. Many businesses track only external costs and dramatically underestimate their true cost per hire.
Benchmarks by role type
Cost per hire varies enormously by role type and seniority. Replacement hires for well-defined roles typically cost less because the role specification is clear and the talent pool is broad. Senior and specialist roles cost more — executive search fees alone can reach 30% of salary. Tech roles in competitive markets carry premium costs. Benchmark against businesses of similar size and sector, not generic averages, for the most useful comparison.
Channels with the lowest cost per hire
Employee referrals consistently produce the lowest cost per hire across research. Referred candidates are cheaper to source, faster to close (trust is pre-established), and retain better (they came knowing the culture). Building a robust referral programme — with meaningful incentives, easy submission processes, and quick feedback loops — is one of the highest ROI investments in talent acquisition. LinkedIn sourcing and direct headhunting by internal recruiters also typically beat contingency agencies on cost.
Reducing cost per hire through employer brand
The most sustainable way to reduce cost per hire is to build an employer brand that makes candidates want to work for you — reducing dependence on expensive intermediaries. Investment includes: a careers page communicating culture authentically, employee-generated content on social media, participation in employer awards, and a reputation for treating candidates respectfully. A strong employer brand compounds over time — the recruiting equivalent of organic SEO versus paid advertising.
