This simple calculator helps you to estimate the potential financial benefits of an ergonomics intervention that you are planning to make. The calculation is based on the salary of the employee or average salary of the employees when more than one employee will be affected; the number of employees; the expected productivity increase and the cost per employee of the intervention. For your guidance a 1% productivity increase is a performance change of less than 1 minute per hour. A Washington State study of office ergonomics showed the median productivity increase following an ergonomic intervention was 12%.To use the calculator:
The calculator will show you the estimated 1 year and 3 years % return on investment (ROI), and the payback period for the intervention.
