Work Hours Estimate

Calculate hours worked between a start time and end time after subtracting break minutes.

Important estimate limitations

This workplace calculator provides an estimate only and is not legal, tax, payroll, HR, financial, accounting, or employment advice. Pay, overtime, time card, holiday pay, deductions, and final paycheck results can depend on employer policy, payroll records, tax rules, labor rules, and individual facts. Verify important results with your employer, payroll records, official labor guidance, or a qualified professional.

How this work hours calculator works

The calculator finds the time between start and end, then subtracts unpaid break minutes. If the end time is earlier than the start time, it treats the shift as crossing midnight.

The result appears as decimal hours and hours plus minutes. Decimal hours are rounded to two places for display, while the hours-and-minutes line rounds to the nearest minute.

Use this page for one shift. Use the time card calculator for clock times across several days, or the weekly hours calculator when you already know each day's decimal total.

Example work hours calculation

If you start at 9:00 AM, end at 5:30 PM, and take a 30-minute unpaid break, the estimate is 8.00 worked hours.

If you start at 10:00 PM and end at 6:00 AM with a 30-minute break, the estimate is 7.50 worked hours.

When to verify the result

  • Your employer rounds clock punches.
  • Meal breaks are paid or partially paid.
  • You worked an overnight shift.
  • Time records include travel, on-call, or training time.
  • Payroll uses a different timekeeping system.

Break-time caution

Enter only break minutes that should be excluded from worked time. Federal guidance generally treats short rest periods as worked time and applies separate conditions to bona fide meal periods; state rules and the facts of the break can also matter.
