💡 Overtime Rule: In the US, non-exempt employees must be paid 1.5x their regular rate for any hours worked over 40 in a workweek (Fair Labor Standards Act).
How to Calculate Work Hours
Calculating work hours involves finding the difference between clock-in and clock-out times, then subtracting any unpaid breaks.
Daily Hours = (Clock Out - Clock In) - Lunch Break
Weekly Hours = Sum of all daily hours
Overtime = Weekly Hours - 40 (if > 40)
Weekly Hours = Sum of all daily hours
Overtime = Weekly Hours - 40 (if > 40)
Example: Standard 40-Hour Week
| Day | Clock In | Clock Out | Lunch | Hours Worked |
|---|---|---|---|---|
| Monday | 9:00 AM | 5:00 PM | 30 min | 7.5 |
| Tuesday | 9:00 AM | 5:00 PM | 30 min | 7.5 |
| Wednesday | 9:00 AM | 5:00 PM | 30 min | 7.5 |
| Thursday | 9:00 AM | 5:00 PM | 30 min | 7.5 |
| Friday | 9:00 AM | 5:00 PM | 30 min | 7.5 |
| Total | 37.5 hours |
Overtime Pay Calculation
If you work 45 hours in a week at $20/hour with 1.5x overtime:
- Regular Pay: 40 hours × $20 = $800
- Overtime Pay: 5 hours × ($20 × 1.5) = 5 × $30 = $150
- Total Gross Pay: $800 + $150 = $950
Tips for Accurate Time Tracking
- Record daily: Don't rely on memory. Log your hours every day.
- Track breaks: Some states require paid rest breaks (15 min) but unpaid meal breaks (30+ min).
- Keep copies: Save your time cards in case of payroll disputes.
- Know your rights: The FLSA requires employers to keep accurate records of hours worked.
⚠️ Legal Note: This calculator provides estimates only. Actual pay may vary based on your employer's policies, state labor laws, and tax withholdings. Consult HR or a payroll professional for official calculations.
