Direct answer
Calculate base pay for paid hours, then add the night differential only for hours that qualify under the policy.
Some policies apply differential only to certain hours, not the whole shift.
Use this answer for estimating weekly pay when some or all hours qualify for night differential. Before relying on it, compare the inputs with your pay stub, offer letter, payroll setting, benefits record, or employer pay policy.
Open Shift Differential CalculatorFormula and worked example
Formula: Night shift gross pay = base pay + qualifying night hours × differential amount.
Example: 40 hours at $22/hour plus a $2/hour differential for all 40 hours gives $880 base + $80 premium = $960 gross.
Keep the formula and the example visible when you change inputs. That makes it easier to spot whether the difference came from hours, dates, pay frequency, or policy wording.

Step-by-step method
Key checks
- Write down the pay rate, hours, salary, pay period, overtime, premiums, taxes, and deductions before calculating.
- Calculate the simplest version first so the baseline is clear.
- Apply the rule: Night shift gross pay = base pay + qualifying night hours × differential amount.
- Adjust for gross versus net pay, pay frequency, overtime eligibility, tax assumptions, deductions, bonuses, and premiums only when those details are part of the real situation.
- Compare the result with your pay stub, offer letter, payroll setting, benefits record, or employer pay policy before using it for a real paycheck estimate, job offer comparison, raise review, or budget plan.
What can change the answer
The result can change when gross versus net pay, pay frequency, overtime eligibility, tax assumptions, deductions, bonuses, and premiums are involved. That does not make the calculator unreliable; it means the inputs need to match the real rule.
If the result is for planning, a close estimate may be enough. If it affects pay, PTO, notice timing, or a formal deadline, use the official record as the final source.
A good habit is to change one input at a time. That shows whether the schedule, pay rate, date range, or policy detail caused the new result.
Common mistakes
Key checks
- Do not add differential to non-qualifying hours.
- Do not forget overtime if the week exceeds the threshold.
- Do not treat the premium as take-home pay.
