Explanation:

Cost Per Hire is a sum of the resources spent in recruiting a single employee to your organisation. This can include external recruiting costs like job sourcing, background checks, job boards, and marketing costs.
Although hiring costs vary by industry and region, it is always surprising to see the bottom-line figure, after all of the line item costs have been factored in.
There are many individual costs incurred during the hiring process, including advertising costs, in-house recruiters’ salaries, third-party recruiter fees, travel expenses, sign-on bonuses, and employee referral bonuses. For certain high-level jobs, there may be employee relocation costs, as well.
