SHIFT PAY GUIDE
What Is Shift Differential? Rates, Examples & How to Calculate It
Shift differential is extra pay for working hours most people don't want to work — evenings, nights, weekends, and holidays. It's not required by federal law; it's an incentive employers use to staff hard-to-fill shifts. If you work nights in a hospital, a plant, a warehouse, or a 24/7 call center, differential pay is probably a meaningful slice of your paycheck — and the part most likely to be calculated wrong.
How shift differential works
A differential is added on top of your base hourly rate for the hours you work inside a defined window. It comes in two flavors: a flat dollar amount (for example, +$4.00/hour for hours between 7 PM and 7 AM) or a percentage of your base rate (for example, +15% for night hours).
The key detail: the differential applies to the hours actually worked in the window, not to the whole shift. If your shift runs 6 PM to 6 AM and the night window starts at 7 PM, the first hour pays base rate and the remaining eleven pay base + differential. Overnight shifts split across midnight — each hour lands where it lands.
Typical differential rates
There's no legal standard, but across US employers the common ranges are:
- —Evening (2nd) shift: $0.50–$2.00/hr, or 5–10% of base
- —Night (3rd) shift: $2.00–$7.00/hr, or 10–20% of base
- —Hospital nursing nights: commonly $3.00–$8.00/hr, with some systems paying 15–25%
- —Weekend differential: $1.00–$5.00/hr, often stackable with night differential
- —Charge/preceptor add-ons (nursing): $1.00–$2.50/hr on top of everything else
How differential stacks with overtime
This is where paychecks go wrong. Under the FLSA, overtime is 1.5× your regular rate of pay — and the regular rate must include shift differentials. If your base is $30 and you averaged $2.50/hr in differentials that week, your overtime hours pay 1.5 × $32.50, not 1.5 × $30.
If your employer computes OT on base rate alone, each OT hour underpays you by 1.5× the differential. Over a year of regular overtime that's real money.
Calculating your differential pay
For a single shift: count the hours inside the differential window, multiply by the differential, add your base pay. For a week with overtime: compute base pay + all differential pay, divide by total hours to get your regular rate, then pay 1.5× that rate for hours past 40.
Or skip the spreadsheet: our free shift differential calculator does the stacking correctly, and the ShiftCheck app does it for every shift you paint on the calendar — automatically, all month.

FAQ
Is shift differential required by law?
No. Federal law doesn't require differential pay — it's an employer incentive. But once paid, it must be included in your regular rate when calculating overtime under the FLSA.
Is shift differential taxed differently?
No. Differential pay is ordinary wages and is taxed exactly like your base pay. It can push your withholding up simply because you earned more.
Do salaried employees get shift differential?
Sometimes — many hospitals pay salaried and per-diem staff differentials — but it's less common than for hourly workers. Check your employer's compensation policy.
Does differential apply to my whole shift?
Usually only to the hours worked inside the differential window. A 6 PM–6 AM shift with a 7 PM window start earns differential on 11 of the 12 hours.
