Employee Return on Investment Calculator
What is employee ROI?



How is employee ROI calculated?
Our employee return on investment calculator takes into account how much investment that team member has from the company and the output of the employee to calculate the overall cost of that employee to the business.
To do this, we consider a range of different factors:
- Average salary
- Average number of work days per year
- % cost to your organisation (including national insurance, pensions, and benefits costs)
- Average number of days absent per employee per year
Daily value from my employees
This number helps us understand the cost of being sick more than national average
Employee working at 75% productivity
Employee working at 50% productivity
Employee working at 25% productivity
Employee working at 0% productivity

Onebright understands that sickness days are a fact of life and we will all need to take them now and again. We also know that stress or ill mental health are the top reason to take time off – both short term and long term.
