This calculator provides an educational pay estimate for the standard hourly scenarios it supports. Overtime rules can vary by employee status, workweek, industry, alternative schedules, pay type, agreements, and other facts.

California overtime rules

For the standard nonexempt hourly scenario, California combines daily, weekly and seventh-consecutive-day rules. Daily hours above 8 through 12 receive the 1.5× category; above 12 receive 2×. This engine assigns each hour one category and adds premiums to straight-time earnings. Valid alternative workweek schedules can use different daily rules and are outside this model.

Federal overtime rules

The federal comparison assigns the first 40 actually worked hours in the selected workweek as regular and hours above 40 as 1.5× overtime. It applies no general daily overtime or double time. Federal estimate = base straight-time earnings + supported bonus + 0.5 × unrounded regular rate × federal overtime hours.

Daily overtime and double time

Daily thresholds are exact: 8 hours has no daily overtime; 8.01 has 0.01 overtime hours. At 12 hours there are 4 overtime hours and no double time; 12.01 has 4 overtime and 0.01 double-time hours. Standard California daily categories are the first 8 regular, hours above 8 through 12 overtime, and hours above 12 double time.

Seventh consecutive day

All seven days of the selected workweek must have hours greater than zero. On its seventh day, the first 8 hours are overtime and hours above 8 are double time. Any zero-hour day breaks this condition. Changing the workweek start retains calendar-keyed hours and rates and changes the workweek order; the seventh day is not necessarily Sunday.

Weekly overtime

California weekly overtime reclassifies otherwise-regular hours above 40 as overtime. The deterministic policy classifies daily and seventh-day overtime/double time first, then allocates the remaining regular hours in workweek order. Federal weekly overtime simply counts all hours actually worked above 40. Only worked hours count; paid vacation, PTO, holiday hours not worked and sick leave are excluded.

How multiple hourly rates affect regular rate

Base straight-time earnings = sum of all hours × each day’s assigned rate, including overtime and double-time hours. Weighted regular rate = (base straight-time earnings + supported includable bonus) / total worked hours. Rates are weighted by hours, not averaged as a list; neither the highest nor last rate controls. At one rate without a bonus, regular rate equals that rate. This matrix supports one hourly rate per day, not multiple rates within a day.

For work paid by completed units rather than an hourly rate, examine the separate piece-rate earnings model. Its output does not establish the legally required regular rate or overtime pay for a mixed compensation arrangement.

How supported bonuses affect regular rate

The optional bonus is an includable production/hourly nondiscretionary bonus allocated across this workweek. It is included in regular-rate compensation and added to total pay once. California estimate = base + bonus + 0.5 × regular rate × overtime hours + 1.0 × regular rate × double-time hours. California flat-sum bonuses can require a different overtime calculation and are not modeled by this field. Discretionary gifts/bonuses, expense reimbursements, vacation/holiday pay and statutory exclusions are not automatically included. Unsupported bonus selections suppress the estimate and explain the limitation.

California vs federal comparison

A schedule can contain daily California overtime without exceeding 40 total weekly hours, so its California and federal estimates can differ. The result-side comparison uses the same entered schedule, weighted regular rate and bonus for both frameworks. Reasons describe affected daily workdays, weekly overtime hours and the seventh day using engine data. Estimated difference under these modeled rules is California estimate minus federal estimate; it is not a legal outcome.

When examining staffing assumptions, compare a separate employee-turnover cost scenario using explicit replacement and vacancy inputs. Neither model establishes that overtime reduces turnover or determines statutory compensation.

To convert supported weekly gross pay to other periods, keep the assumed hours, paid weeks and overtime treatment explicit. Avoid applying an overtime adjustment twice; gross pay is not take-home pay or total employer labor cost.

Why overtime hours are not double-counted

Every worked hour belongs to exactly one of regular, overtime or double time. Daily/seventh-day categories are assigned before weekly reclassification; an already-premium hour is never classified a second time. REG + OT + DT equals total worked hours. All hours receive base earnings once, and only the additional 0.5 or 1.0 regular-rate premium is added. This prevents both hour pyramiding and double-paying base wages.

Special schedules and exceptions

This calculator assumes a standard nonexempt hourly employee and does not determine exemption status. Alternative workweeks, certain healthcare schedules, agricultural rules, collective bargaining arrangements and specialized wage-order exceptions require separate analysis. The optional No / Not sure scope check warns but still allows educational use. Consult the linked California exceptions guidance for special schedules.

Worked examples

Assumptions and limitations

Hours are 0–24 per day, at most 168 per week. Hourly rates are 0–1,000,000 and supported bonuses 0–1,000,000,000; inputs are bounded to 32 characters. Nonfinite values, negative values and malformed active inputs remove current results and disable copying. Combined magnitudes above 1 quadrillion are rejected. With zero hours and zero bonus the estimate is zero and regular rate undefined; a positive bonus with no worked hours is invalid. No automatic minimum-wage compliance validation occurs. Hours display up to two decimals normally and money two decimals; tiny nonzero values remain distinguishable from zero. Premiums use full internal precision. Currency changes formatting without FX conversion. Calculations run locally with no accounts, saved payroll records, storage, URL-state persistence or network calculations.

This calculator provides an educational pay estimate for the standard hourly scenarios it supports. Overtime rules can vary by employee status, workweek, industry, alternative schedules, pay type, agreements, and other facts.

Unsupported scenarios: exempt employees; valid alternative workweek schedules; healthcare 8/80 arrangements; agricultural special rules; union/CBA-specific overtime systems; public-sector special rules; piece-rate employees; commissions; California flat-sum bonuses; salary-based overtime; local ordinance nuances; prevailing wage; split-shift premiums; meal/rest premiums; reporting-time pay; multiple hourly rates within one workday.

FAQ

How is overtime calculated in California?

In this standard hourly model, daily hours above 8 through 12 are overtime and above 12 double time; seventh-day and weekly rules also apply without double-counting.

When does California double time apply?

This model assigns daily hours above 12 to double time and hours above 8 on the seventh consecutive worked day of the selected workweek to double time.

How does seventh-day overtime work in California?

When all seven workweek days have worked hours, the seventh day’s first 8 hours are overtime and additional hours double time. A zero-hour day prevents this condition.

How is federal overtime calculated?

Federal comparison uses hours actually worked above 40 in one workweek. Base pay for all hours is counted first, then an additional half of the weighted regular rate is added per overtime hour.

Why can California overtime differ from federal overtime?

California can assign daily or seventh-day premiums even when total weekly worked hours do not exceed 40. This federal model has only a weekly threshold.

How is the regular rate calculated when I work at multiple hourly rates?

Add all hours multiplied by their assigned rates plus the supported includable bonus, then divide by total worked hours. A simple average of rate values is incorrect.

Do bonuses affect the regular rate of pay?

The supported production/hourly nondiscretionary bonus increases regular-rate compensation. California flat-sum bonuses and other unsupported payment types are not generalized into this field.

Can the same hour count as both daily and weekly overtime?

No. Each hour receives one category. Daily and seventh-day overtime/double time are classified first; only remaining otherwise-regular hours can become weekly overtime.

Does this calculator work for alternative workweek schedules?

No. Valid alternative workweeks and special-industry arrangements can use other rules. This simplified calculator assumes the standard nonexempt hourly scenario.

Is this calculator a final legal payroll determination?

No. It produces an educational pay estimate under the supported rules. Employee status, schedules, pay types, agreements and other facts can change actual pay.
