The calculator model, coefficients, impact estimates and savings scenarios are based on internal WLLNSS analysis and established research on absenteeism, presenteeism, workplace health and employee productivity.

The model estimates potential health-related productivity loss using company size, average salary, workforce structure, benefits setup and productivity-health challenges. It then estimates the portion of this loss that may be addressable through a structured employee health and wellness program.

Sources considered in the model include WLLNSS internal research, McKinsey Health Institute, WHO Europe, EU-OSHA, Deloitte, Baicker, Cutler & Song, Pelletier et al. and Chapman.

This calculator provides a directional business estimate only. It is not a medical, actuarial or financial audit. Actual results depend on workforce profile, participation, implementation quality and company-specific health and productivity data.
