Manufacturing Shift Pay Calculator
Factory and plant workers on rotating shifts need a calculator that handles both shift differentials and weekly overtime accurately. Enter your schedule to see exactly what you'll earn — no guessing, no surprises on payday.
Weekly schedule
Enter your total hours for each day. If the shift included overtime or a differential (evening, night, weekend, or holiday), use the dropdown to select the shift type — the pay split is calculated automatically.

How Manufacturing Shift Pay Is Calculated
Second and Third Shift Differential Rates
- • First shift (6am–2pm): base rate only, no differential
- • Second shift (2pm–10pm): $0.50–$1.50/hr flat or 5%–10% of base
- • Third shift (10pm–6am): $1.00–$2.50/hr flat or 10%–15% of base
- • Unionized facilities: differentials set by collective bargaining, often higher
- • 12-hour rotating shifts: many plants use flat-rate premiums regardless of time of day
FLSA Overtime for Factory Workers
Non-exempt manufacturing workers earn overtime at 1.5× their regular rate of pay for any hours over 40 in a workweek. The regular rate of pay includes shift differentials — so a $1.50/hr third-shift premium raises both your straight-time effective rate and the base from which overtime is calculated. Unionized workers should check their CBA for any more favorable overtime terms.
Rotating Schedules: Calculating a Mixed Week
A common manufacturing scenario: Monday–Wednesday on first shift (no differential), Thursday–Friday on third shift ($1.50/hr differential), plus one Saturday overtime. Enter each day with the correct shift type, log your hours, and set the differentials. Shift Diff Calculator applies the right differential per day and overtime for the Saturday hours in a single calculation.
Do Differentials Change With Your Base Rate?
If your differential is percentage-based, it scales automatically when your base rate changes. A 10% second-shift differential at $18/hr = $1.80/hr extra. After a raise to $20/hr, the same 10% differential becomes $2.00/hr — no renegotiation needed. Flat-rate differentials ($1.50/hr) stay fixed until changed by policy or contract.
Questions, answered
Frequently asked questions
What is a typical shift differential for second and third shift manufacturing workers?
Second shift (afternoon/evening) differentials in manufacturing typically run $0.50–$1.50/hr flat or 5%–10% of base pay. Third shift (overnight) differentials commonly range from $1.00–$2.50/hr or 10%–15%. Heavy industrial and unionized facilities often offer higher premiums due to collective bargaining agreements.
How does the FLSA calculate overtime for manufacturing shift workers?
Under the FLSA, non-exempt manufacturing workers earn overtime at 1.5× their regular rate of pay for hours worked over 40 in a workweek. The regular rate includes shift differentials — meaning a $1.50/hr night premium raises your regular rate and therefore your overtime rate as well.
If I rotate between shifts, how do I calculate my pay for the week?
Log each day with the correct shift type in Shift Diff Calculator. For example, Monday–Wednesday on day shift and Thursday–Friday on night shift. The calculator applies the correct differential to each day, sums total hours, applies overtime if you exceed 40, and gives you your gross pay for the full week.
Do differential rates change when a factory changes production schedules?
Shift differential rates are set by employer policy or union contract, not by production schedule. If your employer changes shift hours without adjusting the differential, your previous rate still applies to the hours that qualify. Any changes to differential rates require a policy update or contract renegotiation.
Does shift differential pay apply to overtime hours in a factory setting?
Yes. If you work overtime during a differential-eligible shift (like overnight), the differential still applies to those hours. Your overtime multiplier (1.5×) is calculated on your base rate, and the differential is paid separately on top of it.
