How to Calculate Work Hours & Overtime

⏱️ How Work Hours Are Calculated

Total work hours for a day = (Time Out - Time In) - Break Duration. Our calculator converts all times to decimal hours for accurate calculations. For example, working from 9:00 AM to 5:00 PM with a 1-hour lunch break equals 7 work hours.

⏱️ Overtime Calculation Formula

Overtime Hours = Max(0, Total Hours - Overtime Threshold)
Regular Hours = Min(Total Hours, Overtime Threshold)
Gross Pay = (Regular Hours × Hourly Rate) + (Overtime Hours × Hourly Rate × Overtime Multiplier)

Example: 45 total hours, $20/hour, 40-hour threshold, 1.5x overtime
Regular Hours = 40 → Regular Pay = 40 × $20 = $800
Overtime Hours = 5 → Overtime Pay = 5 × $20 × 1.5 = $150
Total Gross Pay = $950

Work Hours Calculator FAQs

How do I enter time correctly?
Use 12-hour or 24-hour format (e.g., 9:00 AM, 1:30 PM, or 9:00, 13:30). Our calculator automatically converts times to decimal hours for accurate calculations.

What is considered overtime?
In the US, the Fair Labor Standards Act (FLSA) requires overtime pay (1.5x) for hours worked over 40 in a workweek. Some states have daily overtime rules (over 8 hours per day). Adjust the threshold in our calculator to match your situation.

Should I include lunch breaks?
Yes! Unpaid meal breaks (typically 30-60 minutes) should be deducted from total work hours. Use the "Break Duration" field for each day.

What's the difference between regular and overtime pay?
Regular pay is your standard hourly rate. Overtime pay is typically 1.5× (time and a half) or 2× (double time) for hours exceeding the threshold.

Can I use this for multiple weeks?
This calculator is designed for a single workweek. For multiple weeks, calculate each week separately or reset after each week.

💡 Pro Tip: Always keep accurate time records for payroll compliance. Many labor laws require employers to maintain timesheet records for 2-3 years. Use our calculator to verify your paycheck calculations.
