How to Use This Calculator

Step-by-Step Instructions

  1. 1Enter your overall shift start and end times, or enter your scheduled total shift duration.
  2. 2Add one or more breaks (e.g. 15-minute paid morning break, 30-minute unpaid lunch, 15-minute paid afternoon break).
  3. 3Toggle each break as Paid or Unpaid.
  4. 4Review net paid working hours, total break duration, and decimal totals.
Calculation Principle

Net Paid Hours Formula

Gross elapsed shift duration minus unpaid break time equals net billable hours. Paid rest breaks remain included in compensable shift hours.

Mathematical FormulaNet Worked Hours = Gross Shift Duration - (Unpaid Break Minutes ÷ 60)

Distinction: Meal Periods vs Rest Breaks

U.S. Federal Guidance on Meal and Rest Breaks

Under U.S. federal guidance, short rest breaks are generally treated differently from bona fide meal periods. State and local rules may impose additional requirements.

Short rest pauses (typically 5 to 20 minutes) are commonly treated as compensable working hours, whereas bona fide meal periods (normally 30 minutes or longer during which an employee is completely relieved of all work duties) are generally unpaid and deducted from shift hours.

Practical Worked Example
8.5-Hour Shift with 15m Paid Rest and 30m Unpaid Lunch

Shift from 08:30 to 17:00 (510 minutes elapsed).

Calculation Steps
  • •Break 1: 15-minute rest break (Paid). Does not reduce compensable time.
  • •Break 2: 30-minute meal break (Unpaid). Deducted from elapsed time: 510m - 30m = 480m.
  • •Net paid work time = 480 minutes ÷ 60 = 8.00 billable hours.
Final Calculated ResultElapsed: 8h 30m · Unpaid Breaks: 30m · Net Paid Hours: 8.00 hrs.
Common Pitfalls to Avoid

Frequent Calculation Mistakes

  • ✕Deducting short rest periods (5–20 minutes) that are legally compensable in many jurisdictions.
  • ✕Entering break minutes greater than the total shift duration.
Frequently Asked Questions

Questions & Answers

Are employers required to pay for 15-minute breaks?

Under U.S. federal guidance, short rest breaks (typically 5 to 20 minutes) are generally treated differently from bona fide meal periods (usually 30+ minutes where the employee is relieved of duties) and are commonly compensable. State and local rules may impose additional requirements.
