How to Use

Overtime Calculation Standards: Standard US Federal FLSA rules mandate 1.5x overtime for hours worked in excess of 40 hours per workweek. State-level rules (such as California) additionally mandate 1.5x pay after 8 daily hours and 2.0x double-time pay after 12 daily hours.

Unpaid Meal Breaks: Bona fide meal periods (typically 30 minutes or more) are not considered work time and are automatically subtracted from gross shift hours.

FAQs

How is FLSA overtime calculated in the US?

Under the Fair Labor Standards Act (FLSA), covered non-exempt employees must receive overtime pay for hours worked over 40 in a workweek at a rate not less than 1.5 times their regular rate of pay.

Does California have daily overtime rules?

Yes. In California, non-exempt employees earn 1.5x overtime for hours worked beyond 8 up to 12 in a single workday, and 2.0x double-time pay for hours worked beyond 12 in a single workday.

Are lunch breaks paid or unpaid?

Bona fide meal periods (typically 30 minutes or longer) where the employee is completely relieved from duty are not considered work time and are unpaid.

Use Cases

Estimate weekly gross pay for hourly workers

Input hourly rate, overtime and double time rates, and set daily/weekly limits to see total gross pay including overtime and double time, after break deductions.

Example: Hourly rate $20, overtime 1.5x, double time 2.0x, weekly limit 40 hrs, daily limit 8 hrs.

Plan timecards and budget for overtime costs

Managers can use it to forecast labor costs by adjusting overtime limits and break deductions, helping to stay within budget.

Example: Compare gross pay with 8-hour daily limit vs. 10-hour daily limit.

Frequently Asked Questions

How does the calculator determine overtime and double time?
It uses your hourly rate, overtime rate (default 1.5x), double time rate (default 2.0x), and the weekly and daily overtime limits you set. Hours worked beyond the daily limit are counted as overtime, and hours beyond the weekly limit are counted as double time, with break deductions applied.
What is the FLSA overtime rule?
Under the Fair Labor Standards Act (FLSA), non-exempt employees must receive overtime pay at least 1.5 times their regular rate for hours worked over 40 in a workweek. This calculator lets you set your weekly overtime limit (default 40 hours) to match that rule.
Can I use this calculator for salaried employees?
No, this calculator is designed for hourly employees. It requires an hourly rate and overtime/double time rates. For salaried employees, overtime calculations differ and are not supported here.

Tips & Common Mistakes

Tips

  • Enter your exact hourly rate and overtime/double time multipliers as per your employment agreement.
  • Set the weekly overtime limit to 40 hours to align with standard FLSA rules, unless your state or company has different thresholds.
  • Include all break deductions accurately to get a true gross pay estimate.
  • Use this calculator as a planning tool; always verify with your payroll department for official pay calculations.

Common Mistakes to Avoid

  • Forgetting to set the daily overtime limit, which can cause overtime to be undercounted if you work more than that limit in a day.
  • Using the same rate for overtime and double time when your policy specifies different multipliers (e.g., 1.5x and 2.0x).
  • Not deducting unpaid breaks, leading to an overestimated gross pay.
