The Regular Rate Problem: Why Every Commission Plan in California Is a Ticking Clock

The regular rate is a computed figure, not a contractual one. It is the employee’s total straight-time compensation for the workweek divided by the hours that compensation was intended to cover, and it must include every form of non-discretionary compensation — commissions, non-discretionary bonuses, piece-rate earnings, shift differentials, incentive payments, and service charge distributions.

Because it is computed weekly, it moves. An employee with a stable hourly wage can have a different regular rate in every week of a quarter, depending on what non-hourly compensation was earned. Any payroll process that treats the regular rate as a stored attribute of the employee rather than as an output of the week’s data will be wrong whenever the compensation mix changes.

Two decisions do most of the work in practice. Ferra v. Loews Hollywood Hotel (2021) 11 Cal.5th 858 holds that meal and rest premiums are paid at the regular rate rather than the base hourly rate — which means every premium paid at base since that decision is short. Alvarado v. Dart Container (2018) 4 Cal.5th 542 governs how a flat-sum bonus enters the calculation.

The most consequential error in this area is treating all non-hourly compensation the same way. It is not treated the same way, and the distinction is worth stating carefully because it changes the arithmetic in both directions.

A flat-sum bonus — an amount that does not increase with hours worked, such as a fixed attendance or retention bonus — is divided by the non-overtime hours actually worked in the bonus period under Alvarado, not by total hours. The overtime attributable to that bonus is then paid at one and one-half times the resulting per-hour value. Dividing a flat-sum bonus by total hours understates both the per-hour value and the resulting overtime obligation.

Production-based compensation behaves differently. Commissions, piece-rate earnings, and similar payments that increase with output are divided by total hours worked, and because straight time for all hours is already embedded in the payment, the additional obligation for overtime hours is the half-time premium rather than time and a half.

The boundary is drawn by Alvarado itself. The Court expressly limited its decision “to flat sum bonuses comparable to the attendance bonus at issue here” — a fifteen-dollar payment for working a full weekend shift — in a footnote at page 561. Lemm v. Ecolab Inc. (2023) 87 Cal.App.5th 159 enforced that limit. A plaintiff who argued Alvarado compelled the DLSE flat-sum formula for a monthly percentage bonus lost on summary adjudication, and the Court of Appeal held the employer’s method under the federal regulation complied with both federal and California law. The rationale is worth having in hand because it explains the rule rather than restating it: a bonus computed as a percentage of gross earnings has already had overtime folded into the figure it was calculated on, so applying the flat-sum method to it would make the employer pay overtime on overtime.

Getting this backwards in either direction produces a defective model. An employer’s payroll system that applies the total-hours method to a flat-sum bonus is underpaying; a plaintiff’s expert who applies the flat-sum method to commissions is overstating. Both errors are common, and both are visible in the data once the compensation types are correctly classified.

The structural failure sits in the timing. Commission is frequently earned in one workweek but not calculable until a later pay period, when the sale funds or the period closes. When the amount finally becomes known, the employer must go back to the workweek in which it was earned, recompute that week’s regular rate, and pay the difference on the overtime hours worked in that week.

Very few payroll systems do this automatically. The overtime for the earning week has already been paid at a rate that excluded compensation not yet known, and nothing in the ordinary payroll cycle triggers a recomputation. The result is a shortfall that recurs in every period in which deferred compensation is paid, for every employee who worked overtime in the earning week.

The exposure characteristics of that failure are what make it serious. It is systematic rather than episodic, so the violation rate approaches the proportion of the workforce that earns variable compensation and works any overtime. It is invisible on the face of the wage statement, so it is rarely raised until someone runs the analysis. And it is derivative-generating: an incorrect regular rate produces an incorrect hourly rate on the wage statement, which is an independent section 226(a) problem, and it means every premium paid under Ferra was also short.

Take the dealership scenario the Regular Rate Calculator loads by default: a salesperson at seventeen dollars an hour who works forty-five hours in the week and earns thirty-two hundred dollars in commission for the month. The first step is the one payroll systems skip. A monthly commission does not belong to a single workweek; prorated across the month it contributes about seven hundred thirty-eight dollars to this one. Total straight-time compensation for the week is therefore base wages of seven hundred sixty-five dollars plus that commission, divided by the forty-five hours worked — a regular rate of thirty-three dollars and forty-one cents, roughly double the base rate rather than several multiples of it.

The premium on the five overtime hours is half that rate, or eighty-three dollars and fifty-three cents. Paid the ordinary way, at half time on the seventeen-dollar base, it is forty-two dollars and fifty cents. The overtime shortfall is about forty-one dollars for one employee in one week, and the same rate error runs through every premium paid that week: two missed meals and one missed rest at the base rate come to fifty-one dollars, where the regular rate requires one hundred dollars and twenty-three cents. The week’s total gap is ninety dollars and twenty-six cents.

The proration step is worth dwelling on, because getting it wrong is the most common modeling error on either side. Dropping a month of commission into a single week’s divisor produces a regular rate near eighty-six dollars — more than five times base — and every figure downstream inherits the error.

The gap on those five hours is not trivial, and it repeats. Multiply it by the number of commissioned employees, then by the number of weeks in which overtime was worked, and the wage differential alone becomes material before any penalty is applied. Then add the premium shortfall under Ferra for every meal and rest premium paid at the base rate, and the derivative wage statement exposure for every period in which the stated hourly rate was wrong.

These figures are illustrative, and the Regular Rate Calculator on this site runs the same computation on inputs you supply, showing the likely-paid and legally-correct figures side by side with the method applied to each compensation component.

Start with an inventory of every compensation component paid to non-exempt employees, and classify each as discretionary or non-discretionary, and if non-discretionary, as flat-sum or production-based. Most disputes in this area turn out to be classification disputes rather than arithmetic disputes.

Then test the payroll system on a single employee in a single week with a known compensation mix, and compare the system’s output to a hand calculation. This takes an hour and answers the question definitively.

Then check the premium calculation specifically, because it is a distinct code path in most systems and is frequently still keyed to the base rate notwithstanding Ferra.

Then check whether any true-up mechanism exists at all for deferred compensation, and if it does, whether it recomputes the earning week or merely adds the payment to the current week. Adding it to the current week is not compliance; it is a different error.

Finally, check what the wage statement shows for applicable hourly rates, because that is where a regular rate error becomes a second violation with its own penalty structure.
