Work Hours Calculator
Work out a working day with lunch and breaks, then see the weekly and yearly totals and your pay.
How the work hours calculator works
Hours worked = finish − start − unpaid breaks. Paid rest breaks (often 10–15 minutes) should not be deducted.
Weekly hours = daily hours × days worked. Yearly hours = weekly hours × 52.
Pay = hours × hourly rate. For overtime and a different time each day, use the time card calculator.

How do I calculate hours worked?
Subtract the start time from the finish time, then subtract unpaid breaks. 9:00 to 5:30 with a 30-minute lunch is 8 hours.
Should lunch breaks be deducted?
In the US, meal breaks of 30 minutes or more are usually unpaid and deducted; short rest breaks of 5–20 minutes are counted as work time under federal rules. Check your state and employer policy.
How many work hours are in a year?
