The Shift Differential Calculator helps employees and employers calculate additional pay for working non-standard hours. Shift differentials are extra compensation paid to employees who work evening, night, weekend, or holiday shifts beyond their regular schedule.
What is Shift Differential Pay?
Shift differential pay is additional compensation offered to employees who work hours outside the standard 9-to-5, Monday through Friday schedule. This premium pay recognizes the inconvenience of working less desirable hours and compensates employees for disrupting their normal sleep patterns and personal lives.
