From Time and a Half to a Full Overtime Paycheck

Premium hours are not a separate category that sits on top of your paycheck. Time and a half is the premium rate, while the full paycheck also includes straight-time earnings and any other applicable premium hours. Under the Fair Labor Standards Act, any hour over 40 in a workweek is an overtime hour, paid at 1.5 times your regular rate. That is the change from your base wage to a higher rate. But when state daily overtime rules enter the picture, those premium hours combine with weekly overtime hours in a specific order that most payroll systems get wrong. The 40-hour workweek threshold under 29 U.S.C. § 207(a) is the federal cap, and no daily limit exists under federal law. California Labor Code § 510, Colorado COMPS Order #39, Alaska Stat. § 23.10.060, and Nevada NRS 608.018 each add a daily overtime trigger. The result is a combined calculation that depends on which hours are counted first.

An employee in California works 10 hours on Monday, 10 hours on Tuesday, and 8 hours each on Wednesday, Thursday, and Friday. That is 44 total hours. Under federal law alone, the overtime is 4 hours (44 minus 40). Under California law, daily overtime applies after 8 hours in a day Monday and Tuesday each have 2 daily overtime hours, for 4 daily overtime hours. The 4 weekly overtime hours and the 4 daily overtime hours overlap. State rules say that the weekly overtime cap absorbs the daily overtime hours. The total overtime is still 4 hours, paid at 1.5 times the regular rate. The double-time threshold under California law applies after 12 hours in a day. If the employee works 13 hours on Monday, the first 8 hours are straight time, hours 9 through 12 are overtime at 1.5 times the regular rate, and the 13th hour is double time at 2 times the regular rate. The weekly overtime count still uses the total hours over 40, so 13 hours on Monday plus 8 hours on each of the other four days equals 45 hours. That means 5 weekly overtime hours. The 5 weekly overtime hours include the 4 daily overtime hours and the 1 double-time hour. The double-time hour is paid at 2 times the regular rate, which overrides the 1.5 times federal rate for that hour.

The regular rate calculation is the step where most errors happen. An employee earns a flat weekly salary of $800 and a nondiscretionary attendance bonus of $100 in the same workweek. The employee works 45 hours. Total weekly compensation is $900. The regular rate is $900 divided by 45 hours, which equals $20.00 per hour. The overtime pay for the 5 hours over 40 is $20.00 times 1.5, which is $30.00 per overtime hour. Five overtime hours at $30.00 equals $150.00 of overtime pay. Total pay is $900 plus $150, which is $1,050.00. The employer who uses the base hourly wage of $17.78, which is $800 divided by 45 hours, instead of the regular rate of $20.00, calculates overtime pay at $17.78 times 1.5, which is $26.67 per overtime hour. Five overtime hours at $26.67 equals $133.35. The difference is $16.65 underpaid for that single workweek. The regular rate must be recalculated each workweek when bonuses or commissions are paid, not just at hire. A quarterly bonus that covers 13 workweeks requires the employer to allocate the bonus back across those weeks and recalculate overtime for each week in the bonus period. Failure to do so is a common omission.

The question of how premium hours combine with regular hours under weekly and daily overtime rules has a single mechanical answer. The workweek under 29 CFR 778.105 is a fixed, recurring 168-hour period. Overtime is calculated per workweek, not per pay period. An employer cannot average hours across two weeks in a biweekly pay period to avoid overtime in one week. The 8/80 hospital system under 29 CFR 778.601 is an exception for healthcare employers, allowing overtime after 8 hours in a day or 80 hours in 14 days. State daily overtime rules apply in addition to the federal 40-hour threshold. The combination works this way: count daily overtime hours first, then count weekly overtime hours. The weekly overtime hours include the daily overtime hours if the total exceeds 40. The daily overtime hours are not added on top of the weekly overtime hours. The double-time hours under California law after 12 hours in a day are paid at 2 times the regular rate, which replaces the 1.5 times rate for those hours. The regular rate calculation under 29 CFR 778.108-778.122 includes all nondiscretionary compensation, including shift differentials and commissions. The regular rate is dollars per hour. The overtime multiplier is 1.5 times the regular rate. The failure case is the employer who pays overtime at 1.5 times the base wage, ignoring the higher regular rate that includes bonuses and commissions.
