How it works & common questions
How to calculate net hours and overtime
Tracking payroll hours requires converting clock times into decimal hours while properly subtracting unpaid meal breaks:
- Net shift hours:
(Clock Out − Clock In − Unpaid Break Minutes) / 60 minutes. For example, 8:30 AM to 5:00 PM with a 30-minute unpaid lunch equals 8.0 hours net work time (8.5 total clock hours minus 0.5 break hours). - Overnight shifts: When a worker clocks in during the evening and clocks out the following morning (e.g. 10:00 PM to 6:30 AM), 24 hours are added to the checkout time to compute the true elapsed shift length.
- Overtime split: Hours above your entered weekly threshold use your entered overtime multiplier.
A worked example
Suppose an employee works five shifts during a weekly pay period at a base rate of $20.00/hr:
- Monday through Thursday: 8:30 AM to 5:30 PM with a 30-minute unpaid lunch = 8.5 net hours per day (34.0 hours total).
- Friday: 8:30 AM to 5:30 PM with a 30-minute unpaid lunch = 8.5 net hours.
- Total hours worked: 42.50 hours.
- Regular pay: 40.00 hours × $20.00/hr = $800.00.
- Overtime pay: 2.50 hours × ($20.00 × 1.5 = $30.00/hr) = $75.00.
- Total gross pay: $875.00 before payroll taxes.
Common mistakes
Do not confuse clock minutes with decimal hours: 7 hours and 15 minutes is 7.25 hours, not 7.15 hours. Enter only unpaid breaks that apply to your workplace. This tool does not determine break or overtime eligibility.
