How to Calculate Work Hours

Calculating work hours accurately is essential for employees, freelancers, and employers. Whether you're tracking time for payroll, billing clients, or managing your own schedule, our work hours calculator makes the process simple and error-free.

Understanding Work Hours Calculation

The basic formula for calculating work hours is:

Net Hours = End Time - Start Time - Break Time

For example, if you work from 9:00 AM to 5:00 PM with a 30-minute lunch break:

  • Gross hours: 8 hours (5:00 PM - 9:00 AM)
  • Break time: 0.5 hours (30 minutes)
  • Net hours: 7.5 hours

Common Work Hours Scenarios

  • Standard 9-5: 8 gross hours, typically 7.5 net hours with lunch
  • Part-time shift: Calculate exact hours worked for accurate payment
  • Overtime tracking: Identify hours over 8 per day for overtime pay
  • Freelance billing: Track billable hours for client invoicing

Tips for Accurate Time Tracking

  • Record times as soon as you start and end work
  • Include all unpaid breaks in your break time calculation
  • Use the same time format consistently (24-hour recommended)
  • Double-check overnight shift calculations
