12-Hour Shift Pay Calculator
Print| Per Shift Pay (12 Hours) | $0.00 |
| Annual Gross Pay (52 Wks) | $0.00 |
Working 12-hour shifts is standard across healthcare, emergency services, oil and gas, and continuous manufacturing industries. Schedules such as 3-on / 4-off or the popular 2-2-3 rotating schedule generate unique weekly pay patterns, combining regular hours, daily/weekly overtime premiums, and evening or night shift differential pay.
Our free 12-Hour Shift Pay Calculator computes your total regular pay, overtime compensation, night shift differential earnings, and total weekly gross income.
How to Calculate 12-Hour Shift Pay & Overtime
12-hour shift earnings depend on federal, state (e.g., California daily overtime rules), and employer-specific shift differential policies.
Standard Federal Overtime Rule (FLSA – Weekly Threshold):
Regular Pay = 40 Hours × Base Hourly Rate
Overtime Pay = ( Total Weekly Hours - 40 ) × ( Base Hourly Rate × 1.5 )
California Daily Overtime Rule (Daily Threshold):
In California, working a 12-hour shift automatically incurs daily overtime:
Daily Regular Pay = 8 Hours × Base Hourly Rate
Daily Overtime Pay = 4 Hours × ( Base Hourly Rate × 1.5 )
Shift Differential Premium Formula:
Shift Differential Earnings = Night Shift Hours × Shift Differential Hourly Rate
Common 12-Hour Shift Schedules Comparison
Typical 12-hour work rotas generate alternating bi-weekly pay totals:
| Schedule Pattern | Week 1 Hours | Week 2 Hours | Bi-Weekly Overtime Hours |
|---|---|---|---|
| 3-On / 4-Off (Healthcare / Nursing) | 36 Hours (3 shifts) | 36 Hours (3 shifts) | 0 Overtime Hours (72 total regular) |
| 2-2-3 Pitman Schedule | 48 Hours (4 shifts) | 36 Hours (3 shifts) | 8 Overtime Hours in Week 1 |
| 4-On / 4-Off Rotating | 48 Hours (4 shifts) | 36 Hours (3 shifts) | 8 Overtime Hours in Week 1 |
Step-by-Step Calculation Example
A registered nurse works a 48-hour week (4 × 12-hour night shifts) with the following pay terms:
- Base Hourly Wage: $35.00 / hour
- Night Shift Differential: +$4.00 / hour ($39.00 / hour regular night rate)
- Overtime Threshold: Above 40 hours per week (1.5 × $35.00 = $52.50 OT rate)
- Overtime Shift Differential: +$4.00 / hour ($56.50 total OT night rate)
Step 1: Calculate Regular Pay (First 40 Hours)
Regular Base Pay = 40 Hours × $35.00 = $1,400.00
Regular Night Differential = 40 Hours × $4.00 = $160.00
Step 2: Calculate Overtime Pay (8 Hours Overtime)
Overtime Base Pay = 8 Hours × ( $35.00 × 1.5 ) = 8 × $52.50 = $420.00
Overtime Night Differential = 8 Hours × $4.00 = $32.00
Step 3: Compute Total Weekly Gross Income
Total Weekly Pay = $1,400 + $160 + $420 + $32 = $2,012.00
Frequently Asked Questions (FAQ)
Does shift differential pay get multiplied during overtime hours?
Under the Fair Labor Standards Act (FLSA), shift differential payments must be included in the employee’s “regular rate” when calculating 1.5x overtime premiums.
What is a 2-2-3 schedule (Pitman Schedule)?
The 2-2-3 schedule is a rotating shift pattern where employees work 2 days, take 2 days off, work 3 days, take 2 days off, work 2 days, and take 3 days off over a 2-week cycle, providing every other weekend off.
How many hours is full-time for 12-hour shift nurses?
For most hospital healthcare systems, working three 12-hour shifts per week (36 hours total) is classified as full-time employment with full medical benefits.
