Time and a half (1.5×) pays 150% of your regular hourly wage for any hours worked beyond 40 in a single workweek under the federal Fair Labor Standards Act (FLSA). Double time (2.0×) pays 200% of your regular rate. Double time is not required by federal law, but is legally mandated in California under Labor Code 510 for work beyond 12 daily hours or beyond 8 hours on the 7th consecutive day of a workweek, as well as under union collective bargaining agreements.

1. Quick Answer: Key Differences & Pay Multipliers
Time and a half pays an employee 1.5 times their regular hourly rate for all hours worked beyond 40 in a standard workweek (mandated nationwide under the federal Fair Labor Standards Act). Double time pays an employee 2.0 times their regular hourly rate. Federal law does not mandate double time; it is strictly required under specific state statutes (such as California Labor Code 510), collective bargaining union agreements, or voluntary employer holiday policies.

3. Overtime Rates Table Across Hourly Wage Tiers
This reference table illustrates how straight time, time and a half, and double time pay scale across standard hourly wages:
| Base Hourly Rate | Regular Pay (1.0×) | Time & a Half (1.5×) | Double Time (2.0×) | 8h Double Time Shift Gross |
|---|---|---|---|---|
| $15.00 / hr | $15.00 | $22.50 | $30.00 | $240.00 |
| $20.00 / hr | $20.00 | $30.00 | $40.00 | $320.00 |
| $25.00 / hr | $25.00 | $37.50 | $50.00 | $400.00 |
| $30.00 / hr | $30.00 | $45.00 | $60.00 | $480.00 |
| $40.00 / hr | $40.00 | $60.00 | $80.00 | $640.00 |
| $50.00 / hr | $50.00 | $75.00 | $100.00 | $800.00 |
4. When Does Double Time Legally Apply?
Because double time is not required by federal US Department of Labor statutes, its legal applicability stems from three primary channels:
California is the primary jurisdiction with statutory daily double time under Labor Code 510. Colorado and Alaska mandate daily overtime (1.5x after 12 or 8 hours), but do not have statutory 2.0x multipliers.
Trade unions (including IBEW, SAG-AFTRA, and the Teamsters) routinely negotiate double-time clauses for weekend shifts, emergency callbacks, turnaround penalties, and recognized national holidays.
Many corporate employers offer double-time holiday pay to incentivize shift coverage during Thanksgiving, Christmas, or New Year’s Day. Once formalized in an employee handbook, these policies become legally binding contracts under state wage payment laws.
5. California Labor Code 510: Daily Overtime Framework
California enforces the most comprehensive multi-tier overtime structure in the United States:
- Regular Pay (1.0×): The first 8 hours worked in a single workday.
- Time and a Half (1.5×): Hours worked beyond 8 up to 12 in a single workday, and the first 8 hours worked on the 7th consecutive day of a workweek.
- Double Time (2.0×): All hours worked beyond 12 hours in a single workday, and all hours worked beyond 8 hours on the 7th consecutive day of a workweek.
6. Regular Rate of Pay & Shift Differential Bonuses
Under Department of Labor regulations, overtime multipliers cannot be calculated simply on base contract wage if an employee receives non-discretionary bonuses:
Regular Rate = (Total Straight-Time Earnings + Non-Discretionary Bonuses) ÷ Total Hours Worked. Non-discretionary payments (production bonuses, safety bonuses, shift differentials) increase your regular rate, directly boosting your 1.5× and 2.0× overtime earnings.
7. Frequently Asked Questions
Does federal law require double time on Sundays or holidays?
No. Under the federal FLSA, hours worked on weekends or holidays are treated as standard hours unless they exceed 40 total hours in the workweek. Premium rates depend entirely on employer policies or union contracts.
How do non-discretionary bonuses affect overtime rates?
Non-discretionary bonuses must be added to straight-time wages to calculate your true regular rate of pay before applying 1.5x and 2.0x multipliers, preventing employers from underpaying overtime.
Can an employer mandate double-time shifts?
Yes. In most US states, employers can mandate overtime shifts provided workers receive appropriate statutory premium compensation (1.5x or 2.0x) and the work does not violate federal safety caps (e.g. DOT driver hours).
When does double time kick in for California workers?
Under California Labor Code 510, double time applies to all hours worked beyond 12 hours in a single workday, and all hours worked beyond 8 hours on the 7th consecutive day of work.
