From the work hours guides
Short, practical guides for the questions a weekly total cannot answer by itself.
Start here / 3-minute check
When the numbers differ, compare the date range first, then each clock-in, clock-out and unpaid break. A 09:00–17:30 shift with a 30-minute meal is 8:00 worked; a 60-minute deduction would create a 0:30 gap. Compare exact minutes before the payroll system’s decimal display.
Open the step-by-step checklist →01 / Decimal hours
Convert minutes by dividing by 60, and see why adding rounded daily decimals can differ from the exact weekly total.
02 / Two-week pay
A 38-hour week plus a 45-hour week makes 83:00 worked and five overtime hours at a 40-hour threshold.
03 / Night shifts
Work through 22:00–06:30 and learn when crossing the workweek boundary calls for a manual split.
04 / Breaks
See how an unpaid meal changes worked time, and why the calculator cannot decide whether a break was paid.
02 / Check the math
Each shift is calculated in minutes before it is added to the week. A 9:00–17:30 shift with a 30-minute unpaid meal equals 8:00 worked. Five of those shifts total 40:00; an additional four-hour Saturday shift brings the week to 44:00.
The calculator shows both 44:00 and 44.00 decimal hours. The decimal number is useful when comparing a time card with payroll software, while hours and minutes are easier to check by eye.
See every calculation step →03 / Know the limits
The default overtime threshold is 40 hours per week, with a simple 1.5× pay estimate. For a two-week period, the calculator keeps the overtime split separate for each week. It does not decide which breaks are paid, whether a worker is exempt, or whether state rules require daily overtime. The start of a workweek can also change where an overnight shift belongs.
Use the guides to check those cases before comparing this estimate with a pay statement.

Start with the dates in the pay period, then compare each recorded shift and unpaid break. Check whether a shift crossed midnight or a fixed workweek boundary. Finally, compare total minutes before converting to decimal hours. The time card review checklist walks through this order without asking you to upload private payroll records.
Total worked is elapsed shift time minus the unpaid breaks you entered. Regular and overtime are separated within each fixed seven-day workweek. The default is 40 hours and 1.5× overtime; change those inputs only if they match the rule you want to check. An overnight Sunday shift is assigned across the week boundary by calendar date.
Decimal hours show the same total divided by 60. A displayed 7.50 means seven hours and 30 minutes, not seven hours and 50 minutes. See the conversion guide and the calculation method.
The eight-hour span includes any lunch taken during it. Subtract only an unpaid meal. With 30 unpaid minutes, 9 to 5 yields 7:30 worked.
No. The calculator separates each seven-day workweek before adding a two-week total.
An end time earlier than the start is treated as the following day. A shift across the last day of a workweek is allocated across the boundary by calendar date.
No. It calculates the settings you choose. Check official guidance for exemptions, daily rules and pay adjustments.
