Work Hours Calculator

What Is a Work Hours Calculator?

A work hours calculator helps you track total hours worked across a day or week by calculating the difference between start times, end times, and break deductions. It is useful for freelancers tracking billable hours, employees verifying timesheets, or employers calculating payroll.

How to Calculate Work Hours

The basic formula for daily work hours is:

$$\text{Work Hours} = \text{End Time} - \text{Start Time} - \text{Break Duration}$$

For example, if you work from 9:00 AM to 5:30 PM with a 30-minute lunch break, your work hours are: 8.5 - 0.5 = 8 hours.

Converting Minutes to Decimal Hours

Payroll systems often use decimal hours. To convert minutes to decimal, divide by 60:

• 15 minutes = 0.25 hours
• 30 minutes = 0.5 hours
• 45 minutes = 0.75 hours

Tracking Overtime Hours

In the United States, hours beyond 40 per week are typically paid at 1.5× the regular rate (time and a half). Track your daily hours and weekly total to know when you cross the overtime threshold.
