How Warehouse Overtime Pay Is Calculated
The 4×10 Schedule and Federal Overtime
Four 10-hour shifts equal exactly 40 hours — right at the federal overtime threshold. Any additional hours trigger time-and-a-half. Work a fifth day or extend a shift past 10 hours and you start earning 1.5× your base rate for every extra hour. At $20/hr, even four extra hours of overtime adds $120 to your paycheck.
Typical Warehouse Differential Rates
- • Evening shift (3pm–11pm): $0.50–$1.50/hr flat or 5%–8% of base
- • Overnight/third shift (11pm–7am): $1.00–$2.50/hr flat or 8%–15% of base
- • Weekend premium: $0.50–$1.00/hr flat or 5%–10% of base
- • Peak season bonus: varies widely by employer — enter as a base rate adjustment
How Differentials Affect Your Overtime Rate
Under the FLSA, shift differentials are included when calculating your regular rate of pay for overtime purposes. If you earn $20/hr base plus a $1.50/hr night differential, your effective regular rate for overtime is higher than $20. That means your 1.5× overtime rate is calculated on the blended rate — which is why your overtime check can vary based on which shifts generated those overtime hours.
California Warehouse Workers: Daily OT Rules
California warehouse workers earn overtime after 8 hours in any single day — meaning a standard 10-hour shift already generates 2 overtime hours. Four 10-hour shifts = 8 overtime hours per week even with no extra shifts. Select CA as your state and the calculator applies daily overtime automatically.
Questions, answered
Frequently asked questions
How is overtime calculated on a 4×10 warehouse schedule?
On a standard 4×10 schedule you work 40 hours a week — right at the federal overtime threshold. Overtime kicks in only if you exceed 40 hours (e.g., a fifth shift or extra hours). In California, daily overtime applies after 8 hours in a single day, so four 10-hour shifts generates 8 overtime hours per week even with no extra shifts.
Does a shift differential affect my overtime rate in a warehouse?
Under the FLSA, your overtime rate is 1.5× your regular rate of pay. Shift differentials are paid on top of the overtime multiplier — so a $2/hr night differential still applies to any overtime hours you work during that shift.
Is my employer required to pay a night shift differential?
Federal law does not require shift differentials — they are set by company policy or a collective bargaining agreement. However, if your employer has a policy or contract specifying a differential, they must honor it. Warehouse employers commonly offer $0.50–$2.00/hr for overnight shifts to attract workers.
What happens to my overtime if I switch between day and night shifts mid-week?
Overtime is calculated on total hours worked in the week, not per shift. If you work 30 day-shift hours and 15 night-shift hours, you have 5 overtime hours for the week. The shift differential applies only to the night hours; the overtime multiplier applies to all hours over 40.
How do I calculate pay for a week where I cover a colleague's shift?
Just log the extra hours in Shift Diff Calculator under the appropriate shift type (day, night, or weekend). The calculator handles both the overtime math and the differential for each shift type automatically, so covering extra shifts gives you an accurate gross pay total in seconds.
