Step-by-step method

Key checks
  • Write down the raw punch times, corrected times, unpaid breaks, paid breaks, schedule date, workweek boundary, and rounding rule before calculating.
  • Calculate the clean version first so the baseline is visible.
  • Apply the rule: Paid hours = 12.0 shift hours - unpaid lunch hours.
  • Adjust for missed punches, meal breaks, paid rest breaks, overnight work, multiple shifts, rounded punches, holidays, and custom schedules only when those details apply.
  • Compare the result with your time clock export, schedule, manager correction, payroll note, or written timekeeping message before using it for a real timesheet correction, payroll question, work-hours estimate, invoice, or schedule check.

What can change the answer

The answer can change when missed punches, meal breaks, paid rest breaks, overnight work, multiple shifts, rounded punches, holidays, and custom schedules 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.

If the result affects pay, PTO, notice timing, or a formal deadline, treat it as a planning estimate until the official source confirms it.

Common mistakes

Key checks
  • Do not treat all 12 hours as paid if lunch is unpaid.
  • Do not subtract paid rest breaks unless your rule says they are unpaid.
  • Do not check overtime until the full weekly paid total is known.
