How to Calculate Work Hours with Lunch Breaks: FLSA Rules & Formulas

Learn how to deduct lunch breaks from work hours, understand FLSA 29 CFR § 785.19 meal guidelines, and avoid common automatic deduction paycheck errors.

Core Topic Focus:
  • Under 29 CFR § 785.19, an unpaid meal break ordinarily lasts at least 30 minutes (though shorter periods may qualify under special conditions); complete relief from all duties is central.

How to Calculate Overtime Pay: FLSA Formulas, Regular Rates & Examples

Learn how to calculate 1.5x time-and-a-half overtime, determine the statutory regular rate of pay under 29 U.S.C. § 207, and avoid common payroll calculation errors.

Core Topic Focus:
  • Under the federal Fair Labor Standards Act (FLSA 29 U.S.C. § 207), covered nonexempt employees must receive overtime pay of at least 1.5× their regular rate of pay for all hours worked over 40 in a single workweek.
  • Basic Overtime Formula: Overtime Hourly Rate = Base Regular Rate × 1.5. Total Weekly Pay = (40 × Regular Rate) + (Overtime Hours × Overtime Rate).

Biweekly Overtime Explained: Why 80 Hours Does Not Mean Zero Overtime

Learn why federal FLSA law evaluates overtime on a standalone workweek basis (29 CFR § 778.104) and how an 80-hour biweekly paycheck can still include overtime.

Core Topic Focus:
  • Under 29 CFR § 778.104, federal law evaluates overtime on a single-workweek basis: each 7-day (168-hour) workweek stands alone.
  • An employer cannot average hours worked over two weeks: working 45 hours in Week 1 and 35 hours in Week 2 requires 5 hours of overtime pay, even though the total is 80 hours.

How to Read a Pay Stub: Regular Hours, Overtime Hours & Gross Pay

Learn how to read your pay stub hours, verify regular and overtime line items, distinguish gross from net pay, and reconcile timesheets under FLSA recordkeeping rules.

Core Topic Focus:
  • Pay stubs and itemized wage statements typically display designated pay period start and end dates; hours worked outside those calendar dates belong to a different payroll cycle.
  • Employers subject to FLSA recordkeeping requirements must maintain records sufficient to show required hours and wage information. Employee-facing pay-statement formats and disclosure requirements vary by jurisdiction. Many payroll statements separately display regular and overtime earnings, but the exact format varies.
