Combine work lost to full absence days with reduced output during presenteeism. This calculator estimates total lost productive hours, their labor value, and the normal-equivalent capacity remaining in the measurement period.
Lost hours = employees × (absence days × day hours + presenteeism hours × reduction rate); value = lost hours × loaded hourly value
The estimate combines fully lost absence time with only the reduced-output portion of presenteeism hours, avoiding treatment of every affected hour as completely lost.
Avoid double counting: presenteeism-affected hours should exclude hours already recorded as absence.
For 120 employees with 5 eight-hour absence days plus 30 affected hours at 25% lower output, lost time is 5,700 hours. At $38 per hour, estimated value is $216,600.
Employees are still working during those hours, so only the selected output-reduction portion is treated as lost.
Yes. Enter zero affected hours or a zero reduction rate to calculate absence-only productivity loss.
Use a loaded hourly cost or another consistent value of productive labor, but document the choice.
No. It values lost productive hours. Coverage premiums and administration can be modeled in the annual cost calculator.
Record the unavailable portion as absence time and include only remaining worked hours in presenteeism inputs.
