Your Net Work Hours & Pay

How This Lunch Break Calculator Works
This calculator focuses on net paid hours and simple pay estimates for US workers. It does not replace legal advice or full payroll software.
First, the tool converts your clock-in and clock-out times to minutes, including overnight shifts when you select "Next day."
Unpaid lunch and unpaid rest breaks are deducted from your total shift length to arrive at net paid working time.
If you provide an hourly rate, the tool multiplies your net paid hours by that rate to estimate daily and weekly pay. It also checks if projected weekly hours exceed 40 and flags this for potential overtime.
For detailed salary conversions, use our Hourly to Salary Calculator or Weekly Pay Calculator.
What US Workers Need To Know About Lunch Breaks
Federal Law: FLSA Meal & Rest Break Basics
Under the Fair Labor Standards Act, employers are not required to provide lunch or rest breaks at all. If employers do offer breaks, FLSA sets rules on when that time counts as paid work time.
Short rest breaks of 5 to 20 minutes must be paid and counted as hours worked. Meal periods of 30 minutes or more can be unpaid if the employee is completely relieved of all duties during the break.
States With Mandatory Meal Break Laws
Many states go beyond federal minimums. States such as California, Colorado, Connecticut, Delaware, Illinois, Kentucky, Maine, Massachusetts, Minnesota, Nebraska, Nevada, New Hampshire, New York, North Dakota, Oregon, Rhode Island, Tennessee, Vermont, Washington, and West Virginia have meal break rules for adult workers.
Requirements vary by state, industry, and shift length. For example, California generally requires a 30-minute off-duty meal period by the end of the fifth hour for most non-exempt employees.
Paid vs Unpaid Time
If your lunch break is truly off-duty and at least 30 minutes, it can be unpaid. If you answer calls, stay at a workstation, monitor equipment, or perform any tasks during the break, that time must be paid.
This calculator separates paid and unpaid time so you can see the impact of policy on your paycheck. Use our Gross Pay Calculator to see total earnings before deductions.
Lunch Breaks and Overtime Risk
Skipped or shortened lunches can push weekly hours over 40. When that happens, non-exempt workers are typically owed overtime at 1.5 times their regular rate.
This tool flags when your projected weekly hours cross 40. For full overtime pay math, combine this with our Overtime Calculator and Salary with Overtime Calculator.

Lunch Breaks, Paid Time & US Law
No. The Fair Labor Standards Act does not require employers to provide lunch or meal breaks at all. If an employer offers a lunch break of 30 minutes or more and you are completely relieved of duties, that time can be unpaid. Short rest breaks of 5 to 20 minutes must be paid and counted as hours worked.
Start with your total shift length and subtract any unpaid break time. For example, if you work 8:00 AM to 5:00 PM (9 hours total) with a 30-minute unpaid lunch, your net paid hours are 8.5 hours. This calculator does the math for you and also includes paid rest breaks when appropriate.
States including California, Colorado, Connecticut, Delaware, Illinois, Kentucky, Maine, Massachusetts, Minnesota, Nebraska, Nevada, New Hampshire, New York, North Dakota, Oregon, Rhode Island, Tennessee, Vermont, Washington, and West Virginia have meal break rules for many adult workers. Details vary by shift length, industry, and age. Always check a current state-specific guide for exact requirements.
A lunch break is unpaid when it lasts at least 30 minutes and you are completely relieved of all duties. If you must answer calls, respond to messages, monitor equipment, or stay at your workstation during the break, that time must be paid under FLSA. This is true even if your employer calls it a "lunch break."
If your unpaid lunch is properly deducted, your weekly paid hours might stay below 40. If lunches are missed or you work through them, those extra hours can push your total above 40. Any hours above 40 in a workweek generally must be paid at 1.5 times your regular rate. Use this tool plus our Overtime Calculator to see the impact.
Federal law does not require 15-minute breaks, but if an employer provides breaks of 5 to 20 minutes, they must be paid. Several states require paid rest breaks in certain industries or after a set number of hours. This calculator assumes short breaks are paid unless you specify otherwise.
Automatic meal period deductions are common in many workplaces, but employers must reverse the deduction if you did not actually take the break or if you worked through it. If your timesheet shows less paid time than you actually worked, raise the issue with your supervisor or HR. Under FLSA, you must be paid for all hours worked.
