Direct answer
Add the night differential to the qualifying hours, then combine that premium with regular gross pay.
Night premium needs separate tracking if the shift also has overtime or holiday pay.
Before you use the number, tie it to the actual source in front of you: schedule, punch record, pay stub, PTO system, invoice terms, or policy note.
Open Shift Differential CalculatorFormula and worked example
Formula: Gross pay = regular gross pay + qualifying night differential pay.
Example: Example: 40 regular hours at 18 plus 10 night hours with a 2 premium adds 20 gross premium pay.
Keep the worked example visible while you change the inputs. It makes wrong assumptions easier to spot than a single final number.

Step-by-step method
Key checks
- Write down the hours, rate, salary, pay frequency, commission, bonus, tips, deductions, taxes, and unpaid time before calculating.
- Start with the clean version of the calculation, then add the unusual part: paid break, split shift, premium rate, holiday, or closure.
- Apply the rule: Gross pay = regular gross pay + qualifying night differential pay.
- Adjust for gross versus net pay, taxable tips, commission timing, bonus withholding, unpaid leave, deductions, premium rates, and pay frequency only when those details apply.
- Compare the result with your pay stub, offer letter, commission plan, benefits election, payroll setting, or deduction notice before using it for a real paycheck estimate, job comparison, raise review, payroll question, or budget note.
What can change the answer
The answer can change when gross versus net pay, taxable tips, commission timing, bonus withholding, unpaid leave, deductions, premium rates, and pay frequency are part of the real situation.
The calculator is still useful; the important step is matching the inputs to the record, schedule, paycheck, or policy you are checking.
When the result changes money, time off, or a deadline, write down the assumption that moved the number and verify it against the official record.
Common mistakes
Key checks
- Do not apply the premium to every hour worked.
- Do not treat the differential as take-home pay.
- Do not forget that overnight hours may cross two dates.

Use Shift Differential Calculator when you want to test this question with real inputs instead of doing the math from memory.
Copy the result with the assumptions beside it: dates, hours, pay rate, break treatment, deduction period, or policy detail.
Use the related guides when the next question is different from the first one. A time-card answer can become a paycheck question; a PTO answer can become a deadline question.
