What Is Shift Differential Pay?
Shift differential pay is additional compensation offered to employees who work outside standard daytime hours. This includes night shifts, evening shifts, weekends, and holidays.
How Shift Differential Is Calculated
There are two common methods:
1. Percentage-Based Differential
New Rate = Base Rate × (1 + Differential Percentage)
2. Flat Rate Differential
New Rate = Base Rate + Flat Premium Amount

|---|---|---|---|
| $20 | 10% | 8 | $176 |
| $18 | $2 | 8 | $160 |
