How this pay is calculated

From your hourly rate, shift count, breaks, and overtime rules to weekly and annual earnings.

  1. Paid hours per shift

    H=12−break minutes60H = 12 - \frac{\text{break minutes}}{60}

    Each shift is 12 hours. Unpaid breaks reduce paid time.

  2. Split regular and overtime hours

    Regular hours are capped at 8 per shift. Extra paid hours earn 1.5× the hourly rate.

  3. Annualize weekly pay

    Annual pay=Weekly pay×52\text{Annual pay} = \text{Weekly pay} \times 52

    Bi-weekly pay doubles the weekly total. Monthly pay spreads 52 weeks across 12 months.

How to estimate 12-hour shift earnings

Twelve-hour shifts are common in healthcare, manufacturing, security, and logistics. This calculator estimates daily, weekly, monthly, and annual pay from your hourly rate, how many shifts you work each week, unpaid break time, and overtime rules. All math runs in your browser.

Enter your hourly pay rate, shifts per week, and break minutes. Choose whether overtime is counted per shift, per week, or not at all. The tool subtracts unpaid breaks from the 12-hour block, splits regular and overtime hours, and annualizes the weekly total. Managers tracking staffing reliability can pair pay estimates with the absence percentage calculator to see what share of scheduled shifts were missed.

Paid hours per shift

H=12−break minutes60H = 12 - \frac{\text{break minutes}}{60}

A 12-hour shift with a 30-minute unpaid break leaves 11.5 paid hours. Only paid hours count toward regular and overtime pay.

Overtime pay

OT pay=OT hours×hourly rate×multiplier\text{OT pay} = \text{OT hours} \times \text{hourly rate} \times \text{multiplier}

With daily overtime, hours above your per-shift threshold earn the multiplier on top of the regular rate. With weekly overtime, all paid hours in the week are added first, then hours above the weekly threshold earn the multiplier. A multiplier of 1.5 is time-and-a-half; 2.0 is double time.

Annual and monthly estimates

Annual pay=Weekly pay×52\text{Annual pay} = \text{Weekly pay} \times 52

Bi-weekly pay is twice the weekly amount. Monthly pay spreads 52 weeks evenly across 12 months. These are estimates for budgeting; actual paychecks may differ if your employer uses a different pay period or rounding rules.

Frequently asked questions

How are unpaid breaks handled?
Break minutes are subtracted from the 12-hour shift before pay is calculated. A 30-minute unpaid break on a 12-hour shift leaves 11.5 paid hours.
What is the difference between daily and weekly overtime?
Daily overtime applies the threshold to each shift separately. Weekly overtime adds all paid hours across the week first, then pays the multiplier only on hours above the weekly threshold.
What overtime multiplier should I use?
Time-and-a-half is 1.5× the regular hourly rate. Double time is 2.0×. Enter the multiplier your employer or local rules require; this tool does not enforce a specific law.
How is monthly pay estimated?
Monthly pay equals weekly pay multiplied by 52 weeks, divided by 12 months. That assumes you work the same schedule every week of the year.
