Steps
Calculate net worked hours (Gross shift time minus unpaid break)
Split into standard regular hours (up to 8h) and overtime hours
Compute total earnings: (Reg Hours × Wage) + (OT Hours × Wage × 1.5)
Quick Answer & Understanding Your Result
A Work Hours calculator determines your total billable working time by subtracting unpaid lunch breaks from your clock-in and clock-out t×tamps across daily shifts and weekly payroll cycles.
Standard Shift & Payroll Benchmarks
- Daily Net Hours: Clock Out - Clock In - Unpaid Meal Break.
- Regular Hours: Up to 40.0 hours per week (standard full-time threshold).
- Overtime Hours (1.5x Pay): All hours worked exceeding 40.0 hours in a single 7-day workweek under Fair Labor Standards Act (FLSA) regulations.
- Gross Pay: ( Regular Hours × Hourly Rate) + ( Overtime Hours × Hourly Rate × 1.5).
Enter your daily start t×, end t×, and lunch breaks above to calculate your total weekly hours and gross earnings.
Formula & Calculation Logic
Mathematical FormulaEvaluates timesheet hours against the 40-hour FLSA weekly overtime statutory threshold.
Step-by-Step Guide
Input Daily Start and End Times
Enter clock-in and clock-out times for Monday through Sunday.
Enter Meal Breaks
Deduct unpaid lunch breaks (e.g., 30 min, 60 min).
Enter Hourly Wage
Input standard hourly pay rate ($/hr or VND/hr).
