how to calculate employee roi
To compute the ROI for hiring employees, we will use our net income and asset investment values using the traditional ROI formula: ROI = $ 197,500 (Net Income) / $ 150,000 (Asset Investment or the Salary of New Hires) x 100.ROI = 131.67%.ence, if the HR group reduces its hiring costs for the current year, this would mean that the companyâs operation has the potential to increase its net income by the amount of the cost reduction initiated by the Human Resources department. The use of this concept in calculating ROI is called Cost Reduction.
