1
Enter your shift and break details
Input your gross shift length in minutes, lunch break duration, number of rest breaks, and each rest break's length. For example, a 9-hour shift is 540 minutes with a 60-minute lunch and two 15-minute rest breaks.

Tips

Know Which Breaks Are Paid

Under federal law (FLSA), short rest breaks of 5-20 minutes are generally considered paid time. Only bona fide meal periods of 30+ minutes are typically unpaid. In 2026, 21 states have additional break requirements beyond federal law.

Account for Overtime Break Requirements

For shifts over 8 hours, many states require an additional 10-15 minute paid break. A 10-hour shift with a 60-minute lunch and three 15-minute rests yields 495 net minutes (8.25 hrs).

Use Weekly Projections for Budgeting

The insights panel projects your daily break pattern over a 5-day week. For example, 90 minutes of daily breaks equals 450 minutes (7.5 hours) of unpaid time per week -- nearly a full lost shift.

Compare Shift Structures

Run the calculator with different break configurations to find the most productive setup. Two 10-minute rests instead of two 15-minute rests saves 50 minutes per week while still meeting most state requirements.

Understanding Break Time Deductions in 2026

Accurately calculating net worked time is essential for both employees tracking productive hours and employers ensuring fair payroll.

In 2026, the U.S. Department of Labor reports over 167 million workers affected by break time policies.

This calculator subtracts your lunch and rest breaks from the gross shift to reveal exactly how many minutes -- and hours -- you are actually working.

The Break Time Deduction Formula

The core calculation is straightforward subtraction.

The calculator sums all break durations, then removes that total from the gross shift time.

Net Worked Minutes = Gross Shift Minutes - Lunch Break Minutes - (Number of Rest Breaks x Each Break Minutes)

Shift Type	Gross Minutes	Lunch	Rest Breaks	Total Breaks	Net Minutes	Net Hours	Paid %
Standard 8-hr	480	30	2 x 10	50	430	7.17	89.6%
Full 9-hr	540	60	2 x 15	90	450	7.50	83.3%
Healthcare 12-hr	720	30	3 x 15	75	645	10.75	89.6%
Part-time 6-hr	360	30	1 x 10	40	320	5.33	88.9%

💡 Under the FLSA, short rest breaks (5-20 minutes) are generally paid time. Only enter truly unpaid breaks for the most accurate net paid time calculation. Check your state's 2026 labor code for specific requirements.

How Break Ratios Impact Your Annual Earnings

Small differences in daily break time compound significantly over a year.

Understanding the financial impact helps you make informed decisions about shift structures and break policies.

For a worker earning $25/hour over 260 workdays in 2026:

30 min daily breaks: 7.50 hrs/day paid, $48,750/year
60 min daily breaks: 7.00 hrs/day paid, $45,500/year
90 min daily breaks: 6.50 hrs/day paid, $42,250/year

The difference between a 30-minute and 90-minute daily break schedule is $6,500 per year -- equivalent to losing 260 paid hours.

💡 If your employer provides a 60-minute unpaid lunch but you only need 30 minutes, ask whether a shorter lunch with an earlier departure is an option. This effectively adds 130 hours of personal time back to your year.

Weekly and Monthly Break Projections

Projecting daily break deductions over longer periods reveals patterns that single-day calculations miss.

A daily 90-minute break deduction translates to 7.5 hours per week of unpaid time -- nearly a full shift.

For scheduling and labor compliance in 2026, many payroll systems now auto-calculate these deductions.

However, manual verification remains important for employees who want to confirm their paychecks reflect actual worked hours, especially when overtime thresholds depend on net (not gross) time.

The History of Break Time Regulation

Break time deduction practices trace back to the Fair Labor Standards Act (FLSA) of 1938, signed by President Franklin D.

Roosevelt.

The FLSA established minimum wage, overtime eligibility, and recordkeeping requirements that shaped how employers account for non-productive time.

The U.S. Department of Labor later clarified that short rest periods (5-20 minutes) are paid work time, while bona fide meal periods (30+ minutes) may be unpaid if the employee is completely relieved from duty.

As of 2026, this federal framework remains the baseline, though 21 states have enacted stricter break requirements covering meal periods, rest breaks, or both.

Frequently Asked Questions

What is the difference between gross and net shift time?

Gross shift time is the total duration from clock-in to clock-out, including all breaks. Net shift time is the actual time spent performing duties after unpaid breaks are deducted. For example, a 9-hour (540-minute) gross shift with 90 minutes of breaks yields 450 net minutes, or 7.50 hours of paid work.

Are all breaks legally required to be deducted from pay?

No. Under the Fair Labor Standards Act (FLSA), short rest breaks of 5-20 minutes are generally considered paid working time. Only bona fide meal periods of 30 minutes or more are typically unpaid, provided the employee is completely relieved from duty. State laws vary -- as of 2026, 21 states have additional break requirements.

How does break time deduction affect hourly pay calculations?

Break deductions reduce your total paid hours. If you work a 540-minute gross shift with 90 minutes of unpaid breaks, you are paid for 450 minutes (7.50 hours). At $20/hour, that is $150 instead of $180, a $30 daily difference that compounds to $7,800 annually over 260 workdays.

What is a typical paid time percentage for a full-time shift?

Most full-time shifts have a paid time percentage between 80% and 90%. A standard 8-hour shift with a 30-minute unpaid lunch yields 93.75% paid time, while a 9-hour shift with a 60-minute lunch and two 15-minute rests yields 83.3%. Anything below 75% may indicate excessive break allocation.

How do I calculate net time for irregular break patterns?

If your rest breaks vary in length, add them up and divide by the number of breaks to get an average duration. For example, if you take a 10-minute and a 20-minute rest break, enter 2 breaks at 15 minutes each. The total deduction (30 minutes) will be the same.

Does this calculator account for paid vs. unpaid breaks separately?

This calculator deducts all entered breaks from the gross shift to show the worst-case net time. If your employer pays for rest breaks (as most do for breaks under 20 minutes), only enter the unpaid breaks -- typically just the lunch period -- for an accurate net paid time figure.
