California has specific laws governing overtime pay, ensuring that employees are compensated fairly for hours worked beyond the standard workweek or workday. This calculator helps you estimate your overtime earnings based on California's regulations.
Key California Overtime Rules:
Daily Overtime: You are entitled to overtime pay for all hours worked in excess of eight (8) hours in any single workday. The overtime rate for daily overtime is 1.5 times your regular rate of pay.
Double Time: You are entitled to double your regular rate of pay (2 times your regular rate) for all hours worked in excess of 12 hours in any single workday.
Weekly Overtime: You are also entitled to overtime pay for all hours worked in excess of 40 hours in any single workweek. The overtime rate for weekly overtime is 1.5 times your regular rate of pay.
Double Time (Weekly): You are entitled to double your regular rate of pay for all hours worked in excess of 8 hours on the seventh consecutive day of a workweek.
How the Calculator Works:
This calculator simplifies the calculation by focusing on the most common overtime scenarios: daily overtime for hours exceeding 8 in a day, and weekly overtime for hours exceeding 40 in a week. It determines the overtime hours based on the inputs provided and applies the correct multipliers (1.5x and 2x) to your regular hourly rate.
The calculator prioritizes daily overtime. If hours exceed 8 in a day, those are accounted for first. Any remaining hours that contribute to exceeding the 40-hour weekly threshold are also calculated. Hours that qualify for double time (e.g., over 12 hours in a day, or over 8 on the 7th consecutive day) are complex and may require specific conditions not fully captured by simplified daily/weekly inputs alone. This calculator provides an estimation based on standard daily and weekly overtime.
Example Calculation:
Let's say your Regular Hourly Rate is $25.00. You worked 10 hours on Monday, 9 hours on Tuesday, 11 hours on Wednesday, and 12 hours on Thursday, and then 8 hours on Friday.
Total hours worked: 10+9+11+12+8 = 50 hours.
Total regular hours (within the 8hr daily limit or total weekly limit): 8+8+8+8+8 = 40 hours.
Total overtime hours (exceeding 8 in a day and 40 in a week): (10-8) + (9-8) + (11-8) + (12-8) = 2 + 1 + 3 + 4 = 10 hours.
Estimated Overtime Pay: (2 + 1 + 3 + 4) hours * ($25.00 * 1.5) = 10 hours * $37.50/hour = $375.00.
*(Note: This example focuses on standard 1.5x overtime. If any of these days crossed the 12-hour threshold, double time would apply to hours over 12.)*
