Cost Per Hire: How to Calculate It Properly and What It Actually Tells You

Cost per hire is one of the most cited recruiting metrics, and also one of the most commonly miscalculated — most companies count only external costs like job board fees and agency commissions, leaving out the internal cost of recruiter time entirely. That omission usually understates the true cost significantly.

The full formula

Cost per hire = (total external recruiting costs + total internal recruiting costs) ÷ total number of hires in the period. External costs include job board and advertising spend, agency fees, and sourcing tool subscriptions. Internal costs include recruiter and hiring manager time (at a fully loaded hourly rate), referral bonuses, and relocation or onboarding costs directly tied to sourcing.

What most companies leave out

• Recruiter hours spent sourcing and screening, valued at a fully loaded rate — not just their salary divided by hours worked
• Hiring manager time spent in interviews and debriefs, which is real cost even though it isn't billed anywhere
• The cost of thin pipelines: extended time-to-fill has a real cost even when it isn't captured in a per-hire calculation
• Technology costs already being paid for — ATS licenses, sourcing tools — allocated proportionally per hire

Why the number matters beyond reporting

A properly calculated cost per hire is the number that makes the business case for changes to the sourcing process. If recruiter time is the largest hidden cost, a sourcing layer that reduces manual screening time changes the calculation directly — not just by reducing job board spend, but by freeing up the internal hours that were quietly the biggest cost all along.
