Direct answer
Use the best confirmed end time first, mark it as an estimate, subtract unpaid breaks, and compare it with the official correction process.
A missing punch is a record problem before it is a math problem.
Use this answer for estimating a shift total when the end punch is missing or uncertain. Before relying on it, compare the inputs with your time card, schedule, payroll export, or manager-approved timesheet.
Open Hours Worked CalculatorFormula and worked example
Formula: Estimated hours = confirmed or corrected end time minus clock-in time minus unpaid breaks.
Example: If you clocked in at 8:10 AM and your manager confirms a 4:40 PM end time, the raw shift is 8.5 hours before unpaid breaks.
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 clock times, break minutes, schedule dates, rounding rules, and the workweek boundary before calculating.
- Calculate the simplest version first so the baseline is clear.
- Apply the rule: Estimated hours = confirmed or corrected end time minus clock-in time minus unpaid breaks.
- Adjust for unpaid breaks, overnight shifts, split shifts, rounded punches, holidays, weekends, and overtime cutoffs only when those details are part of the real situation.
- Compare the result with your time card, schedule, payroll export, or manager-approved timesheet before using it for a real timesheet, payroll estimate, schedule review, or work-hours note.
What can change the answer
The result can change when unpaid breaks, overnight shifts, split shifts, rounded punches, holidays, weekends, and overtime cutoffs 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 guess an end time and treat it as final payroll data.
- Do not forget unpaid lunch just because the clock-out is missing.
- Do not overwrite the original punch note without keeping the correction reason.
