Lunch Break Calculator

Calculate paid hours after deducting an unpaid lunch break, or include a paid lunch, using exact start and end times.

Formula

Paid hours = Shift end − Shift start − Unpaid lunch.

Example calculation

Shift 9:00-17:30, unpaid lunch 12:00-12:30. Paid hours = 8h 00m = 8.00 decimal hours.

Common mistakes

  • Treating a paid short break as unpaid.
  • Forgetting state laws that require meal breaks (e.g., California after 5 hours).

About this calculator

What the Lunch Break calculator does

Subtract an unpaid lunch break from a shift to find the paid hours that should be reported on a time card. The tool supports both unpaid and paid lunch scenarios, so you can model what happens when an employer reclassifies a break, or when a state law treats short meals as paid time.

When to use it

Use it whenever your employer deducts a fixed or actual lunch period and you want to confirm the paid hours total. It is also helpful when you are settling a question about a missed lunch, when you are tracking lunch lengths across a week to see if you regularly skip part of a meal, or when you are auditing a stub.

How the calculation works

The calculator computes the shift length, deducts the lunch minutes when the lunch is unpaid, and divides the result by 60 for decimal hours. With the paid lunch toggle on, the lunch length is reported but not subtracted. Overnight shifts are handled with the standard 24 hour adjustment.

How to read the result

The output shows total time at work, the lunch length in minutes, paid time in HH:MM, and the decimal-hour value for payroll. Compare paid time to your stub. If the lunch is paid in your handbook but the stub deducted it, the gap is the lunch length times your rate.

Practical example

A 9:00 AM to 5:30 PM shift with a 30 minute unpaid lunch has 8.5 hours of clock time and 8.0 hours of paid time, or 8.00 decimal hours. A 60 minute lunch in the same shift drops paid time to 7.5 hours. The same 30 minute lunch flagged paid keeps paid time at 8.5 hours and adds 0.5 hours of pay back into the day.

Common limitation or caution

If your state requires a paid rest break, or your employer treats short meals as paid, do not deduct that time as unpaid here. The tool only handles the deduction you choose. California requires premium pay when an employer fails to provide a meal break in a long shift, which the tool does not model.

Frequently Asked Questions

Federal law does not require meal breaks. When provided, breaks under 20 minutes are usually paid; longer meal periods of 30+ minutes are usually unpaid. State rules vary.

Before you use the result

Our calculators give quick payroll-time and pay estimates. Your final paycheck depends on factors this tool does not see, including employer policy, state and local rules, time clock rounding, paid versus unpaid breaks, premium pay, deductions, and how your payroll provider applies them.

  • Confirm pay rules with your employer, payroll provider, or HR team.
  • Overtime, breaks, and rounding rules can change by state.
