Subtract only unpaid break time
First calculate the elapsed time from clock-in to clock-out. Then subtract the unpaid lunch duration. Do not deduct a paid break, and never let the deduction reduce worked time below zero.
Example: 8:30 AM to 5:15 PM is 8 hours 45 minutes elapsed. Subtracting a 45-minute unpaid lunch gives exactly 8:00 worked, or 8.00 decimal hours.
Important limitation
Break rules vary by workplace and location. Confirm whether a meal period is paid and how official records round time.
