Employee Return on Investment Calculator
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.
Measuring employee return on investment (ROI) is not an exact science. But our free online ROI calculator below can help you to enhance your HR strategy by calculating the cost of absenteeism and presenteeism.
Our employee return on investment (ROI) calculator takes into account how much investment that team member has from the company (salary, NI, benefits) and the output of the employee (days worked).
What is employee ROI?
Employee ROI measures how much employees are costing a business and whether they are worth the financial investment.
Engaged employees, working in a healthy environment and a thriving culture, are happy and productive, having a positive impact on your company. Our free employee ROI calculator enables you to see exactly what that impact is.
Onebright’s workplace mental health services are designed to help prevent prolonged periods of absence and presenteeism and increase return to work rates.

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
- % cost to your organisation (including national insurance, pensions, and benefits costs)
- Average number of work days per year
- Average number of days absent per employee per year

Why is well-being important for employee ROI?
People are at the forefront of any business and are a vital part of keeping things operating smoothly. However, we know that people also suffer from work stress, burnout, and anxiety. Poor mental health and employee well-being can result in high employee turnover and long-term sickness absences.
By looking after the mental health and well-being of your employees, you can address issues such as employee burnout, ultimately reducing sickness absences and improving staff retention.
Offering your staff good mental health and well-being support can also:
- Improve company culture
- Improve employee output
- Improve productivity and focus
- Improve employee engagement
Therefore, fostering a healthy, supportive workplace environment and advocating for your employees’ mental health can ultimately help you improve employee return on investment.
