How this shift differential calculator works
This calculator applies the shift differential percentage to the regular hourly rate, then multiplies the premium and total rates by the number of hours worked.
Shift differential pay = hourly rate x (differential % / 100) x hours worked
It is helpful for estimating night-shift, weekend-shift, or off-hours pay when your employer pays a percentage premium above the base rate.
Examples
Example 2
A 15% differential on a $24 hourly rate adds $3.60 per hour to the shift.
Example 3
If the differential is 0%, the total shift pay equals the regular shift pay with no added premium.
