What shaped this estimate
8h were classified above the daily 8-hour threshold. Check that each day's hours are attached to the correct calendar day.

Gross-pay estimate for a standard California schedule only. It is not tax withholding, take-home pay, or legal advice.

Gross pay shown on your paystub

Optional. Enter the pre-tax gross for this same workweek to compare it with the estimate. Difference means expected minus entered and is only an arithmetic check of inputs, pay basis, or the paystub.

Is California overtime after 8 hours a day, or 40 hours a week?

Both. Under Labor Code section 510, hours after 8 in a workday pay 1.5x, hours after 12 pay 2x, and eligible hours over 40 in the workweek also pay 1.5x. Hours already paid as daily or seventh-day overtime are not counted again.

On the example week — $25/hr and four 10-hour days — 32 hours stay at $25 and 8 hours go to 1.5x. That's $25 × 32 + $25 × 1.5 × 8 = $1,100. No weekly overtime, because eligible regular hours never passed 40.

  • First 8 hours in a workday: regular rate (1x).
  • Hours after 8, up to 12: 1.5x daily overtime.
  • Hours after 12: 2x double time.
  • Eligible hours over 40 in the workweek: 1.5x weekly overtime. Hours already paid as a daily or seventh-day premium are not counted again.
  • All seven days worked: the seventh day pays the first 8 hours at 1.5x and later hours at 2x.

Changing the workweek start reorders Day 1 through Day 7 and can move which calendar day is the seventh day. The week breakdown lists each day you worked.

Standard California overtime schedule
This estimate applies the standard Labor Code section 510 daily, weekly, double-time, and seventh-day rules — nothing else. Alternative workweeks, CBAs, and special industry schedules are not calculated here. Salary mode treats pay as overtime-eligible on a 40-hour week (annual ÷ 52 ÷ 40). Bonus or commission inputs must be earned entirely in this workweek.

What does each part of the result mean?

Estimated gross pay is the headline number. Everything below it exists so you can check that number:

  • Week breakdown: The button opens one sentence about this week, the money lines that add up to gross, and each day you worked.
  • Copyable summary: a full text version of inputs, formulas, and limits for payroll or HR review.
  • Paystub comparison (optional): expected gross, entered gross, and Difference to review. The difference is arithmetic only; it cannot settle whether the payroll record is correct.

If the numbers still look off, read the limits below before relying on the estimate.

All three use the standard Labor Code section 510 schedule, a Monday-start employer workweek, and a confirmed $25.00 regular rate.

4 × 10 hours

Four 10-hour days total 40 hours, but 8 hours fall above the daily 8-hour threshold.

Expected non-zero rule buckets
  • Regular (1x): 32h at 1x
  • Daily OT (1.5x): 8h at 1.5x
Estimated gross pay
$1,100.00

Practical meaning: This isolates daily overtime without relying on weekly overtime.

Boundary: this does not apply an alternative workweek schedule or another special rule.

6 × 8 hours

Six 8-hour days total 48 hours; the 8 eligible hours above 40 move to weekly overtime.

  • Regular (1x): 40h at 1x
  • Weekly OT (1.5x): 8h at 1.5x
Estimated gross pay

Practical meaning: This shows weekly overtime when no day crosses the daily threshold.

Boundary: this is a standard workweek example, not a timecard or payroll determination.

7 × 8 hours

Seven 8-hour days produce 8 weekly-overtime hours and 8 seventh-day overtime hours.

  • Weekly OT (1.5x): 8h at 1.5x
  • Seventh-day OT (1.5x): 8h at 1.5x
Estimated gross pay
$1,600.00

Practical meaning: The weekly and seventh-day premiums apply to different hours; the calculator does not count either hour twice.

Boundary: confirm the employer-defined workweek start before treating a calendar day as the seventh day.

What do you need before you calculate?

Three things. Only the first one usually needs checking:

  • Your workweek start day. Ask your employer or check the handbook — the calculator does not assume Monday or Sunday, because weekly and seventh-day overtime both depend on this boundary.
  • How you are paid this week. A confirmed regular rate if you already have one; otherwise a single hourly rate, multiple hourly rates, or a nonexempt annual salary on a 40-hour basis.
  • Hours actually worked on each calendar day. Count worked hours only. Meal premiums, off-the-clock time, PTO, and holidays are outside this estimate.

If you are replacing the example week, the workweek start still has to be the employer-defined first day — weekly and seventh-day overtime both depend on it.

Which pay input should you choose?

A base hourly wage is not always the regular rate California uses for overtime. Pick the mode that matches how you actually know your pay:

  • I know my regular rate. Enter it directly. This mode does not add bonus or commission amounts that may already be inside the rate.
  • Single hourly rate. The tool uses your straight-time earnings plus overtime premiums.
  • Multiple hourly rates. Straight-time earnings are weighted by hours at each rate and stay in the gross; 0.5x or 1x premiums come from the weighted rate.
  • Nonexempt annual salary. Annual pay ÷ 52 ÷ 40, for overtime-eligible pay on a 40-hour week.

Nondiscretionary flat-sum bonuses, production bonuses, and commissions earned entirely in this workweek each use a different DIR formula; the tool applies the matching one. Discretionary bonuses, piecework, and cross-week amounts stop the estimate instead of guessing.

When should you not rely on this estimate?

Standard schedule only

This tool follows Labor Code section 510 for a standard schedule. Alternative workweek schedules under section 511, collective bargaining agreements, and special industry Wage Orders are not applied. If your schedule uses those rules, stop here and check the sources below.

Regular rate still has limits

The builder covers confirmed rates, single and multiple hourly rates, nonexempt salary on a 40-hour basis, and this-workweek flat-sum, production, and commission amounts. It does not decide exemption status, allocate multi-week bonuses, or reconstruct cross-midnight workdays from start and end times.

Gross pay, not take-home

Results are pre-tax gross estimates. Withholding, filing status, take-home pay, and the federal OBBBA overtime deduction belong on the dedicated tax tools and guides, not on this page.

Estimate, not legal advice

The estimate is based on the cited standard rules last checked on the date below. It is not legal or payroll advice, and this page does not claim professional review.

Disclaimer
This calculator provides gross-pay estimates based on California Labor Code Section 510 overtime rules for a standard schedule. Actual pay may vary based on your employer's policies, collective bargaining agreements, and pay structure. Some industries have alternative workweek schedules with different overtime thresholds. Always verify final amounts with your employer or HR department. This tool is for informational purposes only and does not constitute legal, payroll, or tax advice.

Frequently Asked Questions

No. California does not conform to the federal OBBBA (Public Law 119-21) overtime deduction. State income tax can still apply to your full overtime pay even when a federal estimate is lower. Use the No Tax on Overtime Calculator for the federal task; this page stays on California gross overtime.
