Break Times

Frequently Asked Questions

Enter your start and end times, then specify your lunch, morning, and afternoon break durations in minutes. The calculator subtracts total break time from your gross hours to give you net working hours.

It depends on your employer and state law. Under federal law (FLSA), short rest breaks of 5–20 minutes are generally paid. Meal breaks of 30+ minutes are typically unpaid if you're completely relieved of duties. Check the "Breaks are paid" box in our calculator if your breaks don't reduce your hours.

No. The Fair Labor Standards Act (FLSA) does not require employers to provide meal or rest breaks. However, many states have their own break laws. California, for example, requires a 30-minute meal break for shifts over 5 hours and a 10-minute rest break for every 4 hours worked.

Break Time Calculator: Laws, Productivity, and Best Practices

Calculating net working hours after break deductions is essential for accurate payroll, time tracking, and labor law compliance. Our Break Time Calculator lets you enter your shift start and end times, specify lunch, morning, and afternoon break durations, and instantly see your net working hours, decimal hours, and total minutes. You can also toggle between paid and unpaid breaks to match your employer's policy.

Federal Break Law: The FLSA Position

Important: The Fair Labor Standards Act (FLSA) does not require employers to provide meal or rest breaks. This surprises many workers. Federal law only requires that if breaks are offered, short rest breaks (5–20 minutes) must be paid as working time, and bona fide meal breaks (30+ minutes where the employee is completely relieved of duties) may be unpaid.

Because federal law sets no break requirement, the rules depend entirely on state law (and sometimes local ordinances). This creates a patchwork where workers in one state have strong protections and workers across the border have none.

Paid vs. Unpaid Breaks

Understanding the distinction between paid and unpaid breaks is critical for accurate time tracking:

Net Working Hours = Gross Hours − Unpaid Break Minutes ÷ 60
If breaks are paid: Net Working Hours = Gross Hours (breaks don't reduce your compensable time)
  • Paid breaks (rest breaks): Short breaks of 5–20 minutes are considered working time under the FLSA. The employee is paid for this time, and it counts toward overtime calculations. These typically include coffee breaks, restroom breaks, and brief personal phone calls.
  • Unpaid breaks (meal breaks): Breaks of 30 minutes or more where the employee is completely relieved of all duties may be unpaid. The key word is "completely"—if a worker must answer phones, monitor equipment, or remain on-call during a meal break, the FLSA considers it a paid break.
Example — Standard 9-to-5 with Breaks: Start: 9:00 AM, End: 5:00 PM. Gross hours: 8:00. Lunch: 30 min (unpaid). Morning break: 15 min (paid). Afternoon break: 15 min (paid). Net working hours: 8:00 − 0:30 = 7:30 (7.5 decimal hours). Weekly: 7.5 × 5 = 37.5 hours.

Optimal Break Patterns for Productivity

Research consistently shows that regular breaks improve focus, creativity, and overall output. Here are evidence-based break patterns:

  • Pomodoro Technique: 25 minutes of focused work followed by a 5-minute break. After 4 cycles, take a 15–30 minute break. This method works well for tasks requiring sustained concentration.
  • 52/17 Rule: A DeskTime study found that the most productive employees worked for 52 minutes and then took a 17-minute break. The breaks involved stepping away from the computer entirely.
  • 90-Minute Ultradian Rhythm: Based on sleep researcher Nathaniel Kleitman's work, the brain cycles through roughly 90-minute periods of higher and lower alertness. Working in 90-minute blocks with 15–20 minute breaks aligns with this natural rhythm.
  • Micro-breaks: Even 30-second breaks to look away from a screen (the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds) can reduce eye strain and mental fatigue.

OSHA Guidelines

OSHA's Position: While OSHA doesn't mandate specific break schedules, it does require that employers provide "reasonable" restroom access (29 CFR 1910.141). OSHA also recommends breaks for workers in extreme heat, repetitive motion jobs, and extended standing positions. In hazardous environments, breaks aren't optional—they're a safety measure.

For specific industries, OSHA and DOT have additional rules: commercial truck drivers must take a 30-minute break within 8 hours of driving (FMCSA Hours of Service), and airline pilots have mandatory rest periods between flights (FAA regulations). Healthcare workers, construction laborers, and warehouse employees also have industry-specific break guidance.

Auto-Deduct Policies: Some employers automatically deduct a 30-minute meal break from every shift, even if the employee worked through lunch. This practice is illegal in many states if the employee was not actually relieved of duties. If your employer auto-deducts breaks you didn't take, consult your state labor department.
