Define cost-per-hire and its components.

• A. Onboarding training costs paid after hire
• B. Advertising costs
• C. Agency fees
• D. Recruiter salaries

Answer: (D)

Cost-per-hire measures the average expense to fill a position, calculated by dividing the total recruiting costs by the number of hires. Among the options, recruiter salaries best represent the core internal cost of running the recruiting function and typically form a large, ongoing portion of what it costs to hire someone. Advertising costs, agency fees, and onboarding/training are all valid expenses in the hiring process, but the salaries of recruiters are the central internal component that scales with each hire. A complete view would sum all relevant costs, but the recruiter salaries option points to the primary internal cost driving the metric.
