What is my shift differential pay? Estimate the premium pay you earn for 2nd shift, 3rd shift, weekend, and holiday hours — as a percentage of your base rate or a fixed dollar amount per hour — plus overtime at 1.5×.
The defaults reflect a common scenario: a $22.00/hr base rate, 40 regular hours, and 8 shift hours at a 15% weekend premium. Adjust the values to match your pay stub or offer letter.
Profile: Base rate $22.00/hr, 40 regular hours, 8 shift hours on a weekend shift at a 15% premium, no overtime
Calculation: Regular pay = 40 × $22.00 = $880.00 | Shift pay = 8 × $22.00 = $176.00 | Differential = $176.00 × 0.15 = $26.40
Profile: Base rate $22.00/hr, 40 regular hours, 8 shift hours at 15%, plus 2 overtime hours at 1.5× (no differential applied to overtime)
Calculation: Overtime pay = $22.00 × 1.5 × 2 = $66.00 | Gross = $880.00 + $176.00 + $26.40 + $66.00 = $1,148.40
Profile: Base rate $22.00/hr, 40 regular hours, 8 shift hours at a fixed $3.00 per hour premium, no overtime
Calculation: Differential = $3.00 × 8 shift hours = $24.00 | Gross = $880.00 + $176.00 + $24.00 = $1,080.00
Note: These examples are for illustration purposes only and use the verified formulas built into this calculator. Results may round to cents. Actual shift differential pay varies by employer, union contract, and state law.
Base Rate = Your normal hourly wage before any premiums
Shift Hours = Hours worked on the premium shift (2nd, 3rd, weekend, or holiday)
Premium = The differential, either a % of the base rate or a fixed $ per hour
Overtime = Hours beyond your regular schedule, paid at 1.5× with no differential applied
Effective Rate = What you actually average per hour across all hours worked
| Shift Type | Typical Differential |
|---|---|
| 2nd Shift (evening) | 5-10% |
| 3rd Shift (night) | 10-15% |
| Weekend | 10-15% |
| Holiday | Up to 50% or time-and-a-half |
Enter your base hourly rate, the number of regular hours you work, and the number of hours you work on the premium shift. The calculator separates shift hours from regular hours so the differential is applied only to the hours that qualify.
Select whether your differential is a percentage of your base rate or a fixed dollar amount per hour. In percent mode, use the quick-set buttons for common premiums — 2nd shift 5%, 3rd shift 10%, weekend 15%, holiday 50% — or type your exact premium. Add any overtime hours worked at 1.5× (no differential is applied to overtime in this calculator).
Click Calculate to see regular pay, shift pay, the differential premium, overtime pay, your gross total, and your effective hourly rate. The step-by-step breakdown shows every component with the formula used so you can verify the math against your pay stub.
Remember: This calculator applies the differential only to shift hours, and overtime at 1.5× without a differential. Some employers include the differential in the overtime base rate, and some states require it — check your employee handbook or state wage regulations for the rules that apply to you.
Shift differential pay is additional compensation — usually a percentage of your base hourly rate or a fixed dollar amount per hour — paid to employees who work less desirable or less convenient shifts. It is most common for 2nd shift (evening), 3rd shift (night), weekend, and holiday hours. For example, a nurse earning $30.00/hr who works nights at a 12% differential earns $33.60/hr for those night hours: the differential is added only to the hours actually worked on the premium shift, not to your entire paycheck.
Why do employers pay it? Employers use shift differentials to attract and retain workers for hard-to-fill hours, to compensate employees for the disruption to their personal schedules, and to recognize the higher demand or additional responsibility that evening, overnight, and holiday coverage often carries. Without a differential, most workers would have little incentive to volunteer for night shifts or holiday rotations, so the premium acts as a market-based incentive that keeps critical operations staffed around the clock.
How it differs from overtime. Overtime is a premium for working more hours — under the FLSA, generally 1.5× your regular rate for every hour over 40 in a workweek. A shift differential is a premium for working at a particular time, regardless of how many hours you work. The two can appear on the same paycheck, and they stack: your differential raises the pay rate for the shift hours themselves, while overtime raises the rate for the extra hours, so a night-shift employee who works overtime can earn both premiums in a single week.
Shift differentials vary widely by industry, region, union contract, and employer policy. The ranges below reflect common market practice and are a useful starting point for estimating your own premium — always confirm the exact rate with your employer or collective bargaining agreement.
| Industry | Typical Differential Range |
|---|---|
| Healthcare & Nursing | 10-15% |
| Manufacturing | 5-10% |
| Call Centers | 10-20% |
| Police & Security | 5-15% |
| Warehouses & Logistics | 5-10% |
By shift type, the pattern is equally consistent. Second (evening) shifts typically earn a modest 5-10% premium, while third (night) shifts earn 10-15% because of the greater disruption to sleep and family schedules. Weekend work usually adds 10-15%, and holiday pay is the richest of all — many employers pay up to 50% extra, and some pay time-and-a-half or even double-time for major holidays. Unionized workplaces often negotiate these rates into the contract, so the negotiated premium can be higher or lower than the market typical.
When comparing job offers, look at the total compensation picture rather than the base rate alone. A job with a lower base rate but a generous night differential can out-earn a higher-base-rate day job for employees willing to work the premium shift. Use this calculator to run both scenarios side by side.
Under the Fair Labor Standards Act (FLSA), nonexempt employees must be paid overtime at 1.5× their regular rate for all hours worked over 40 in a workweek. The regular rate is generally the employee's base hourly rate — but the interaction between shift differentials and overtime is one of the most misunderstood areas of payroll, and the rules differ depending on how your employer structures the pay.
Differential excluded from the overtime base. Many employers pay overtime at 1.5× the base rate only, and pay the shift differential separately on top, exactly as this calculator does. In that model, an employee working 8 night hours and 4 overtime hours in a week earns 1.5× base for the overtime hours plus the differential only on the 8 night hours.
Differential included in the overtime base. Some employers — particularly in healthcare and unionized manufacturing — include shift differential earnings when calculating the regular rate used for overtime. This makes overtime more expensive for the employer, which is why it is usually specified in a union contract or company policy. When the differential is included, overtime for a night-shift employee is computed at 1.5× the blended rate that already reflects the premium, resulting in higher overtime pay.
State rules vary. A number of states have their own wage and hour laws that define how shift differentials must be treated for overtime purposes, and some state laws are more generous than the federal baseline. If you believe your overtime was underpaid, check your state's department of labor website or speak with a wage-and-hour specialist — this calculator is an estimate for planning purposes, not legal or payroll advice.
⚠️ Estimate Only: Pay practices vary by employer, union contract, and state law. This tool is an estimate, not legal or payroll advice — check your employee handbook or state wage regulations before relying on any figure it produces.
When reviewing your shift differential pay, confirm the premium rate, which hours qualify (for example, whether a shift that starts at 2:00 PM counts as 2nd shift), and how the differential interacts with overtime, holiday pay, and paid time off. Keep copies of your schedule and pay stubs, and compare the differential line item on each check against your agreed rate. If you spot a discrepancy, bring it to your payroll department promptly — most employers will correct errors quickly, but only if you flag them.
