How to Calculate Work Hours
What is Work Hours?
A work hours calculator totals your hours worked in a day or week, applying overtime rules. Most countries set 40 hours/week as standard — hours beyond this typically earn 1.5× (time-and-a-half) pay.
Step-by-Step Guide
- 1Total hours = Σ (clock-out − clock-in) for each shift
- 2Overtime = max(0, total hours − 40) × 1.5
- 3Gross pay = (regular hours × rate) + (OT hours × 1.5 × rate)
