Hours Comparison (Shift vs Paid vs Break)

How Lunch Break Deductions Work

When you take a meal break of 30 minutes or more and you are fully free from job duties, that time is usually unpaid. Your employer subtracts it from your shift total before calculating your daily pay.

For example, if you work a 9-hour shift and take a 30-minute unpaid lunch, you get paid for 8.5 hours. Short rest breaks (10–20 minutes) are different — the U.S. Department of Labor says those generally count as paid work time under the Fair Labor Standards Act (FLSA).

Some states and countries go further. California requires a 30-minute unpaid meal break for any shift over 5 hours. The UK requires a 20-minute rest break for shifts over 6 hours. Always check your local rules.

Break Time Calculation Formula

The math is simple once you know which breaks are paid and which are not:

  • Total Shift = End Time − Start Time
  • Unpaid Deduction = Unpaid Meal Break + Extra Unpaid Time
  • Net Paid Hours = Total Shift − Unpaid Deduction
  • Daily Pay = Net Paid Hours × Hourly Rate

Example: 9:00 AM to 6:00 PM = 9 hours. Minus 30-min unpaid lunch = 8.5 paid hours. At $18/hr, daily pay = $153.00.

Break Rules Around the World

Break requirements vary widely by country and state. Here are the key rules for common regions:

  • USA (Federal): No federally required meal break. Short rest breaks (≤20 min) must be paid.
  • California: 30-min unpaid meal break required for shifts over 5 hours. Second meal break for shifts over 10 hours.
  • UK: 20-min unpaid rest break for shifts over 6 hours (Working Time Regulations).
  • EU: 11 hours rest between working days. Rest break after 6 hours — amount set by country.
  • Australia: 30-min unpaid meal break after 5 hours under most awards.
  • Canada: Generally 30-min break for every 5 consecutive hours (varies by province).

Always check your specific state, province, or national labor authority for exact rules that apply to your industry and contract.

Frequently Asked Questions

Subtract your shift start from your shift end to get total shift time. Then subtract any unpaid break minutes. Convert the result to decimal hours by dividing remaining minutes by 60. For example: shift is 9 hours, minus 30-minute unpaid lunch = 8.5 paid hours. Multiply by your hourly rate to get your daily pay.
A 30-minute lunch break is typically unpaid, provided you are fully relieved of all work duties during that time. Under the U.S. Fair Labor Standards Act, a meal break of 30 minutes or more where you are free to leave the premises is not considered work time and does not have to be paid. If you are required to stay at your desk or respond to work during lunch, that time should be paid.
A meal break (lunch break) is usually 30 minutes or longer and is unpaid when you are fully off duty. A rest break is a short break of 10–20 minutes, typically taken mid-morning or mid-afternoon, and is generally counted as paid work time. Some employers offer both types — a 30-minute unpaid lunch and two 10-minute paid rest breaks per day.
Yes, automatic deductions are common and legal, as long as you actually take the break you are not working during it. Problems arise when employees work through lunch but the deduction still happens. If this is happening to you regularly, speak with your employer's HR team or contact your state labor board, as you are owed pay for any time you were actually working.
It depends on your location. Under federal FLSA rules, there is no required meal break for a 6-hour shift. However, many states have their own rules. California, for instance, requires a 30-minute meal break for any shift over 5 hours. The UK requires a 20-minute rest break for shifts over 6 hours. Check your specific state or country labor laws for the rule that applies to you.
For overnight shifts, the end time is past midnight, so you need to add 24 hours to the end time before calculating the difference. For example, a shift from 10:00 PM to 6:00 AM is 8 hours total. This calculator handles overnight shifts automatically when you select the overnight option — just enter your normal times and it adjusts the math.

Break Time as a Percentage of Shift

How much of your total shift is unpaid break time, and how much pay you lose per day.

Break Duration 6-hr Shift 7-hr Shift 8-hr Shift 9-hr Shift 10-hr Shift 12-hr Shift

Break % = Break Time ÷ Total Shift × 100. Helps you understand how much of your day is unpaid.

Weekly Pay Difference — Paid vs Unpaid Break
