California pays overtime on the day: 1.5× the regular rate after 8 hours in a workday, 2× after 12, and 1.5× then 2× on the seventh consecutive day, with 1.5× past 40 straight-time hours in the week (Labor Code §510). Four 10-hour days owe zero federal overtime but eight California overtime hours.
Forty hours across four days is 40 hours federally, so no overtime at all. In California it is eight overtime hours, two per day, because each day passed 8. The gap on a $32 rate is $128 per worker per week, or $6,656 a year, before you multiply by the crew. Hours are never counted twice: each hour is paid at its single highest applicable rate.
How does this calculator work out the pay?
For each day it splits the hours into tiers: up to 8 at 1×, hours 9 to 12 at 1.5×, beyond 12 at 2×. On a seventh consecutive day, the first 8 hours are 1.5× and the rest 2×. Then any straight-time hours beyond 40 in the week move up to 1.5×. Pay is hours in each tier times your wage times 1, 1.5 or 2, and the formula line under the results shows the sum for your inputs. The federal column pays 1.5× only on total weekly hours past 40.
Does a bonus change the overtime rate?
Yes. Overtime is 1.5× the regular rate, and the regular rate is not the hourly wage. It includes nondiscretionary compensation: production bonuses, attendance bonuses, shift differentials, piece-rate earnings and non-hourly incentive pay. Only genuinely discretionary gifts stay out.
California then diverges from federal law on how to fold a bonus in. Under Alvarado v. Dart Container (2018), a flat-sum bonus — a fixed amount that doesn't grow with hours worked, like $100 for finishing the week — is divided by the non-overtime hours actually worked, not by total hours. Federal law (29 CFR §778.110) divides by total hours. Dividing by the larger federal denominator produces a smaller regular rate and therefore underpays the overtime.
What does this calculator leave out?
The comparison above is a floor, not a full payroll engine. It models a uniform schedule at a flat hourly rate and excludes:
- Nondiscretionary bonuses and piece rates in the regular rate — as above, these push the real figure up.
- Meal and rest premiums, which are separate obligations under §226.7 and stack on top. Price those separately
- Alternative workweek schedules, the one lawful route to a 4×10 without daily overtime — see below.
- Compensable travel time under Morillion, which lengthens the workday and can push hours across the 8- and 12-hour thresholds.
- Prevailing-wage and certified-payroll rates on public works, which set their own floors, and union contracts that meet Labor Code §514, which replace daily overtime with the agreement's premium rates.
