Daily overtime may also matter
California overtime can arise from hours over eight in a workday as well as hours over 40 in a workweek. Avoid double counting hours that qualify under more than one threshold.
California overtime calculation
A nondiscretionary bonus can increase California overtime pay
California generally includes a nondiscretionary bonus in the regular rate used for overtime. A production bonus is commonly divided by total hours worked in the earning period, and an additional half-time or full-time premium is then applied to overtime or double-time hours.
Bonus formulas differ. Flat-sum, production, percentage, commission, discretionary, and contractual bonuses may use different regular-rate treatment. Confirm the Industrial Welfare Commission wage order, earning period, and current DLSE guidance.
Classify the bonus before doing arithmetic
A nondiscretionary bonus tied to hours, production, proficiency, or an announced incentive is generally part of the regular rate. A genuinely discretionary gift-like bonus may be excluded. California's DLSE explains that a flat-sum bonus is not divided the same way as a production bonus, so the label and earning formula matter.
$90 production bonus over a 45-hour week
Assume a $20 hourly employee works 45 hours and earns a $90 production bonus for that week. Divide $90 by 45 total hours to get a $2 bonus regular rate. The additional premium attributable to the bonus for five time-and-a-half hours is $2 times 0.5 times 5, or $5. This amount is added to the ordinary hourly wages, overtime premium, and the $90 bonus.
Flat-sum bonuses differ
DLSE guidance says a flat-sum bonus is divided by the maximum legal regular hours in the bonus period, not all actual hours. Do not reuse the production-bonus denominator.
Common pay-stub error
Paying the announced bonus without recalculating the regular rate can leave overtime short. Another error is postponing the adjustment after the bonus amount becomes calculable.
