At $46/hour, a 7 AM–7 PM shift with a 30-minute unpaid lunch is 11.5 paid hours, not 12.
One 12-hour day shift
- Base pay11.5 h × $46.00
- $529.00
- Estimated gross pay
- $529.00
Three of those a week is 34.5 paid hours and $1,587.00 gross — under a 40-hour weekly threshold, so no overtime. Over 52 weeks that's about $82,524.00 before differentials, overtime or pickups (see the hourly to salary calculator).
How 12-hour shift pay works
- Paid hours = 12 minus any unpaid break. A 30-minute unpaid break makes it 11.5; if your breaks are paid, it's 12.
- Overtime depends on your employer. Some pay daily overtime after 8 or 12 hours; many only pay weekly overtime after 40. Three 12s (36 hours) don't reach 40; a fourth usually does.
- Differentials for nights, weekends or charge are added on top. Night 12s (7P–7A) often earn a night differential for all or part of the shift.
For a full week including a pickup shift, use the nurse overtime calculator in "A full week" mode.
Common 12-hour situations
- Day 12 (7A–7P)
- Usually no night differential. Check weekend differential on Saturdays and Sundays.
- Night 12 (7P–7A)
- Turn on night differential; limit it to your employer's night hours if needed.
- Stayed late 30 minutes
- Set the end time to 7:30. With daily overtime after 12, the extra half hour is overtime.
- Fourth 12 this week
- Open Overtime & holiday and set hours already worked this week to 36.
