California Overtime Calculator

Calculate your overtime pay under California labor law. This calculator accounts for daily overtime (time-and-a-half after 8 hours), weekly overtime (after 40 hours), and double time (after 12 hours daily or 8 hours on 7th day).

How It Works
The formula, explained simply

The California overtime calculator determines your daily pay by applying the state's unique overtime laws, which are more worker-friendly than federal standards. California requires overtime compensation based on both daily and weekly hour thresholds, unlike most states that only use weekly calculations.

Daily overtime rules form the foundation of California's system. After working 8 hours in a single day, you earn time-and-a-half (1.5 times your regular rate) for hours 9 through 12. Any hours beyond 12 in a single day are compensated at double time (twice your regular rate). These daily thresholds apply regardless of how many hours you've worked earlier in the week.

Weekly overtime adds another layer of protection. If you work more than 40 hours in a work week, those excess hours must be paid at overtime rates. California combines this with daily rules to ensure you receive the highest applicable rate for each hour worked.

The seventh consecutive day rule provides additional overtime protection. When you work seven days in a row, the entire seventh day is subject to special rates: the first 8 hours are paid at time-and-a-half, and any hours beyond 8 are paid at double time, even if you haven't exceeded other thresholds.

When To Use This
Right tool, right situation

Use the California overtime calculator whenever you work more than 8 hours in a single day, more than 40 hours in a week, or seven consecutive days. California's overtime laws are among the most comprehensive in the United States, providing multiple pathways to earn premium pay that don't exist in other states.

The calculator is essential for employees in industries with variable schedules, such as healthcare, hospitality, retail, and construction. These sectors often require long shifts or consecutive workdays that trigger California's unique overtime provisions. Regular use helps you verify that your paychecks include all applicable overtime premiums.

Employers should use this calculator to ensure compliance with California Labor Code Section 510. Miscalculating overtime can result in wage claims, penalties, and interest charges. The calculator helps payroll departments apply the correct rates when employees work complex schedules that trigger multiple overtime rules.

Freelancers and contractors working hourly arrangements can use the calculator to quote accurate rates for extended projects. Understanding California's overtime structure helps you price your services appropriately when clients request work beyond standard hours.

Common Mistakes
Why results sometimes look wrong

The most common California overtime calculation mistake is ignoring daily thresholds in favor of only weekly calculations. Federal law only requires overtime after 40 weekly hours, but California mandates overtime after 8 daily hours. Employees often miss overtime pay by not tracking daily hours separately from weekly totals.

Another frequent error involves misunderstanding the seventh consecutive day rule. This rule applies to seven consecutive workdays, not calendar days. Working Monday through Sunday doesn't trigger seventh day overtime if you had a day off the previous week. The consecutive day count resets after any day without work.

Employers sometimes incorrectly calculate double time by only applying it to hours beyond 12, while paying hours 9-12 at regular rate. California law requires time-and-a-half for hours 9-12 AND double time for hours beyond 12. Both premium rates apply simultaneously, not exclusively.

Misclassifying employees as exempt is another critical mistake. California's overtime laws apply to non-exempt employees regardless of salary level, unlike federal law. Many salaried employees in California still qualify for overtime if they don't meet specific exemption criteria.

The Math
Worked examples and deeper derivation

California overtime calculations require layering multiple rules to determine the correct rate for each hour worked. The basic formula starts with identifying regular hours (up to 8 per day), daily overtime hours (hours 9-12), and double time hours (beyond 12 per day).

For daily calculations: Regular pay = 8 hours × hourly rate, Daily overtime = (hours worked - 8) × hourly rate × 1.5 (capped at 4 hours), Double time = (hours worked - 12) × hourly rate × 2.

Weekly overtime adjustments apply when total weekly hours exceed 40. The calculator distributes this weekly overtime across workdays, converting regular hours to overtime hours as needed. The formula ensures you receive overtime rates for all hours beyond 40, even if daily thresholds weren't met.

Seventh day calculations override other rules entirely. On the seventh consecutive workday: Hours 1-8 = hourly rate × 2 (if working more than 8 hours) or hourly rate × 1.5 (if working 8 or fewer), Hours beyond 8 = hourly rate × 2.

Earns $640 daily: all 8 hours paid at double-time rate ($80/hour) for working the 7th consecutive day.

Common questions

How does California overtime work for daily hours?
California requires overtime pay after 8 hours in a single workday. Hours 9-12 are paid at time-and-a-half (1.5x regular rate), and hours beyond 12 are paid at double time (2x regular rate). This daily overtime rule applies regardless of weekly hours worked.
What is the 7th day overtime rule in California?
Working 7 consecutive days triggers special overtime rules. The first 8 hours on the 7th day are paid at time-and-a-half, and any hours beyond 8 on the 7th day are paid at double time. This applies even if you haven't exceeded daily or weekly hour thresholds.
How do I calculate overtime pay for multiple California overtime rules?
California overtime calculation combines daily, weekly, and consecutive day rules. Use the most favorable rate for each hour worked. Daily overtime after 8 hours, weekly overtime after 40 hours, double time after 12 daily hours, and 7th consecutive day rules all stack to maximize your overtime compensation.
