Extra payroll earnings for designated shifts, usually added as a premium amount or adjusted rate on qualifying hours.
A shift differential is extra pay for working a designated shift, such as nights, weekends, or another schedule the employer treats as qualifying for premium treatment.

An employee works 20 night-shift hours with a $2 per hour shift differential.

| Qualifying hours | 20 |
| Differential earnings | $40 |
Payroll adds the $40 to the employee’s other earnings and may show it as a separate line on the pay stub.
