Frequently asked questions
What is shift differential pay?
A shift differential is extra pay for working a particular schedule, such as nights or weekends. It may be a dollar amount or percentage set by an employer or agreement.
Is shift differential included in overtime?
Shift differentials can be part of the regular rate used for overtime. This calculator includes the entered hourly differential before applying the overtime multiplier.
What if the differential applies to only some hours?
Calculate only the hours worked on that shift here, or separate the rates and use a blended regular-rate calculation.
What this estimate includes
- The differential is a fixed amount per hour.
- It applies to every regular and overtime hour entered.
- The adjusted rate is the applicable overtime regular rate.
- No other compensation changes the rate.
What can change the result
Multiple rates may need a weighted average
If one workweek includes different jobs or differentials, a blended regular-rate calculation may be required.
