How It Works

How to Calculate Cost Per Hire

Formula

Cost Per Hire = (External Costs + Internal Costs) / Total Hires

This metric follows the ANSI/SHRM standard formula. External costs include agency fees, job board postings, career fairs, and advertising. Internal costs cover recruiter compensation, ATS software, employee referral bonuses, and interview expenses. Tracking cost per hire helps you optimize recruiting budgets and compare sourcing channels.

Worked Example

A company spent $30,000 on external recruiting and $20,000 on internal recruiting to make 10 hires.

external_costs = 30000internal_costs = 20000total_hires = 10
  1. 01Total Recruiting Cost = $30,000 + $20,000 = $50,000
  2. 02Cost Per Hire = $50,000 / 10 = $5,000
  3. 03External Cost Share = $30,000 / $50,000 x 100 = 60%
