How to calculate hours worked

  1. Subtract the start time from the end time. 8:00 AM to 5:30 PM is 9 hours 30 minutes.
  2. Subtract unpaid breaks. Take away the 30-minute lunch and the day is 9:00, or 9.00 hours.
  3. Add the days. Five of those days are 45:00 hours for the week.

A shift that ends after midnight is counted to the next morning: 10:00 PM to 6:30 AM with a 30-minute break is 8:00 hours. The calculator works in whole minutes, so the totals are exact.

Converting minutes to decimal hours

Payroll systems usually want hours as a decimal: divide the minutes by 60. 7 hours 45 minutes is 7.75 hours, not 7.45. The results show both formats.

Overtime

Under the federal Fair Labor Standards Act, covered non-exempt employees must be paid at least one and a half times their regular rate for hours worked over 40 in a workweek (U.S. Department of Labor: overtime pay). In the example, 45 hours is 5 hours of overtime, so gross pay is $800.00 regular plus $150.00 overtime = $950.00.

Some states also require overtime after a set number of hours in a day, and some employers pay a different rate or start overtime earlier. You can change the weekly threshold and the overtime rate; daily overtime is not calculated.

Assumptions and limits

  • Breaks you enter are unpaid and are subtracted; paid breaks should be left out.
  • Times are not rounded. Some employers round punches, for example to the nearest quarter hour.
  • Pay is gross, before taxes and deductions, for one workweek at one hourly rate.
  • Whether you are owed overtime depends on your job and your state; this is not legal advice.

Methodology and testing

Automated tests check hand-worked examples, overnight shifts, odd minutes and custom overtime rules, and compare 2,000 random weeks against an independent calculation using calendar date arithmetic. How we build and test calculators.
