This calculation shows how much overtime pay is due when a covered nonexempt employee earns a base hourly wage plus extra pay for certain shifts. Under the United States federal baseline, the FLSA requires overtime after 40 hours worked in a fixed 168-hour workweek, not after a calendar week, pay period, or schedule cycle.
The key output is the overtime premium based on the employee's regular rate. The regular rate is total compensation for the workweek, excluding statutory exclusions, divided by total hours actually worked in that same workweek. Shift differential pay belongs in that workweek total when it is compensation for hours worked, so base-wage-only overtime understates the result.
A shift differential is not a separate overtime multiplier. It raises the compensation used to find the regular rate, which then raises the overtime premium. The federal baseline requires covered nonexempt employees to receive at least 1.5x the regular rate for hours worked over 40 in the workweek.
Do not average two workweeks to smooth out shift premiums or overtime hours. Each FLSA workweek stands alone, and hours may not be averaged over two or more workweeks to avoid overtime. Federal law also does not create overtime merely because work occurs on Saturdays, Sundays, holidays, or regular days of rest.
Example: a covered nonexempt employee works 45 hours in one FLSA workweek at a $24 base rate. Of those hours, 12 are night-shift hours with a $5 shift differential. Straight-time compensation is 45 × $24, or $1,080. Shift differential pay is 12 × $5, or $60. Total workweek compensation is $1,140.
The regular rate is $1,140 ÷ 45 hours, or $25.33 per hour. Because 5 hours are over 40, the additional overtime premium is 5 × $25.33 × 0.5, or $63.33. Total gross pay for the week is $1,140 + $63.33 = $1,203.33 before taxes, deductions, or policy-based additions.
A one-off calculation is enough when you need to check one workweek, one employee, and a known shift differential. It is also enough for explaining why overtime must use the regular rate instead of only the base hourly wage. Keep the workweek boundary, hours worked, base rate, differential hours, and premium calculation together.
A managed workflow matters when schedules change, differentials vary by shift, or managers need to review overtime before payroll. Everhour Resource Planning shows visual timelines, member and project views, weekly capacity, availability gaps, scheduled time off, and planned-vs-actual time comparisons so teams can spot workload pressure before it becomes payroll cleanup.

Yes. The regular rate is total compensation for the workweek, excluding statutory exclusions, divided by total hours actually worked in that workweek. When shift differential pay is compensation for hours worked, it belongs in the compensation total before the overtime premium is calculated.
For the federal baseline, covered nonexempt employees must receive overtime at not less than 1.5x the regular rate. The regular rate can differ from the base hourly wage because it reflects total workweek compensation divided by total hours worked, including applicable shift premium pay.
The common mistake is paying 1.5x only on the base wage while treating the shift differential as separate flat pay. That misses the regular-rate step. First total the workweek compensation, then divide by total hours worked, then apply the extra half-time overtime premium to hours over 40 when straight time was already paid.
No. The FLSA does not require overtime pay merely because work occurs on Saturdays, Sundays, holidays, or regular days of rest. Under the federal baseline, the trigger is hours worked over 40 in the fixed workweek unless a more protective state law, policy, contract, or agreement applies.
Not under the federal baseline when the time is not worked. The FLSA does not require payment for time not worked, including vacations or federal or non-federal holidays. Holiday, vacation, and similar paid-time benefits are generally set by agreement, employer policy, state law, or a representative or union contract.
Everhour Resource Planning uses visual timelines, member and project views, weekly capacity, availability gaps, scheduled time off, and planned-vs-actual time comparisons. Managers can see where scheduled work is likely to exceed capacity before payroll review turns into a manual overtime correction exercise.
Everhour Overtimes supports daily and weekly overtime limits, 1.5x overtime, and 2x double-overtime tiers. Admins can review overtime in Team Hours, where Everhour surfaces overtime and double-overtime visibility for tracked time before payroll calculations are finalized.
Use Everhour Resource Planning to compare planned assignments with weekly capacity, availability, and scheduled time off before shift coverage turns into unexpected overtime cost.
