Calculate "When Can I Leave?"

Our "End Time" mode is perfect for flexible schedules. If you know you need to hit 40 hours a week but took an extra-long lunch, simply input your start time and goal. The work hour calculator with lunch deduction will tell you the exact minute you can clock out.

Payroll Decimal Conversion

Most payroll software (like ADP or Gusto) requires hours in decimals. 30 minutes is 0.50, while 15 minutes is 0.25. Our tool converts this automatically, preventing rounding errors that can cost you money.

Common Questions

How do I calculate work hours with a 30-minute lunch?

To calculate hours with a 30-minute lunch: 1. Determine total duration (End Time minus Start Time). 2. Subtract 0.5 hours (30 minutes). Our work hours calculator with lunch automates this to ensure your payroll decimals are 100% accurate.

Is lunch break usually paid or unpaid?

Under US FLSA rules, short breaks (5–20 mins) are usually paid, while 'bona fide' meal periods (typically 30+ mins) are unpaid. Our calculator helps you deduct these unpaid periods to find your net billable hours.

What time can I leave work if I started at 8:00 AM?

If you work an 8-hour shift with a 30-minute unpaid lunch, you can leave at 4:30 PM. Use the 'Calculate End Time' tab on our tool to customize this for any shift length.
