How It Works
Weekly hours come together from each day's shift start and end times, minus any unpaid breaks. Tracking them precisely is what separates regular pay from overtime and keeps payroll correct.
Each shift is measured as End Time minus Start Time minus Break Duration, which yields the hours worked that day. Those daily figures are then added up across the week. Hours above 40 in the week are counted as overtime and, if you enter an hourly rate, paid at 1.5 times that rate. The 40-hour weekly threshold is fixed, so daily overtime rules such as California's are not applied.
Accuracy hinges on the details. AM/PM designations are an easy place to slip, so confirm them on every shift. Break durations matter too, even short ones, and the unpaid lunch break is the entry people most often leave out, which quietly inflates the weekly total.
Example: A Week of Shifts
- 1 Input the following for a work week in January 2026: Monday: 9:00 AM - 5:00 PM (30 min break); Tuesday: 9:00 AM - 5:30 PM (30 min break); Wednesday: 8:30 AM - 4:30 PM (1 hour break); Thursday: 9:00 AM - 6:00 PM (30 min break); Friday: 8:00 AM - 5:00 PM (1 hour break).
- 2 The calculator will process each day: Monday (7.5 hours), Tuesday (8 hours), Wednesday (7 hours), Thursday (8.5 hours), Friday (8 hours). It then sums these daily totals.
- 3 The total weekly hours are 39 hours. In this scenario, there are 39 regular hours and 0 overtime hours, assuming a 40-hour workweek threshold.
- 4 This breakdown clearly shows your total compensated time, distinguishing between standard work and any potential overtime, which is crucial for verifying your paycheck's accuracy. This example demonstrates how to account for varying shift lengths and break durations over a typical work week.
