California overtime runs by the day, not just the week — this is the calculation most out-of-state payroll systems get wrong.

About this calculator
Unlike federal law and most states, California pays overtime based on hours worked in a single day, not just hours in a week: 1.5x pay for hours 8 through 12 in a workday, 2x pay for hours beyond 12 in a workday, and on the 7th consecutive day worked in a workweek, 1.5x for the first 8 hours and 2x beyond 8 (Labor Code §510). This tool applies those daily and 7th-day rules to the hours you enter for a single workday, in addition to the standard 40-hour weekly overtime threshold. Results are an estimate only, not legal advice, and actual pay depends on your exact schedule, any applicable alternative workweek agreement, and exemption status.

FAQ
Does California overtime only kick in after 40 hours a week?
No — California also requires daily overtime: 1.5x for hours 8 through 12 worked in a single day and 2x beyond 12 hours, regardless of the weekly total, unless a valid alternative workweek schedule applies.
What is the 7th-consecutive-day rule?
If an employee works all 7 days of a single workweek, the 7th day triggers 1.5x pay for the first 8 hours and 2x for anything beyond 8 hours, even if the weekly total is under 40 hours.
Does this apply to salaried employees?
Only to non-exempt employees. Exempt employees (meeting salary and duties tests) are not entitled to daily or weekly overtime under California law.
Is this legal advice?
No. This is an estimate only, not legal advice — alternative workweek agreements, meal-period premiums, and exemption status can change the actual amount owed, and you should confirm with California's DIR or an employment attorney.
Accuracy and limitations
- Results are estimates before tax, fees, and inflation unless an input explicitly covers them.
- Rates are treated as fixed for the whole period — variable-rate products will drift from this projection.
- This is educational maths, not financial advice. Check anything contractual with the lender or your accountant.
