Hourly Rate ($)

Shifts per Week

Shift Differential ($/hr extra for nights)

Night Shifts per Week

OT Multiplier

OT Threshold (hrs/week)

Formula:
Weekly Hours = Shifts × 12
OT Hours = max(0, Weekly Hours − 40)
Regular Pay = min(Weekly Hours, 40) × Rate
OT Pay = OT Hours × Rate × OT Multiplier

12-Hour Shift Schedules

Common in healthcare, manufacturing, and public safety, 12-hour shifts typically follow patterns like DuPont (4-on/4-off rotating), Pitman (2-3 on/2-3 off), or Panama (2-2-3). Most average about 42 hours per week, triggering 2 hours of overtime.

Overtime Rules

Under FLSA, non-exempt employees earn at least 1.5× their regular rate for hours over 40/week. Some states (like California) also require daily overtime after 8 or 12 hours.
