How the calculations work

Every result is arithmetic on the times and rates you enter. The rules behind the options are taken from official sources:

• Weekly overtime. Hours over 40 in a workweek are paid at no less than 1.5 times the regular rate under the federal Fair Labor Standards Act (29 U.S.C. § 207(a)(1); U.S. Department of Labor: Overtime Pay). Each workweek is calculated on its own; two weeks are never averaged (29 CFR 778.104).
• Daily and California overtime. The California option applies time and a half after 8 hours in a day, double time after 12, and the seventh-consecutive-day rules in California Labor Code § 510 (see also the California DLSE: Overtime FAQ). The daily option applies 1.5× after 8 hours a day or 40 a week without counting the same hour twice.
• Rounding. Optional rounding to the nearest 5 minutes, tenth of an hour or quarter hour follows the practices described in 29 CFR 785.48(b). Quarter-hour rounding is commonly called the 7-minute rule.
• Breaks. Short rest breaks count as hours worked (29 CFR 785.18); bona fide meal periods, ordinarily 30 minutes or more, generally do not (29 CFR 785.19).
• Regular rate. When a shift differential is added, it is included in the regular rate used for overtime (29 CFR 778.207(b); 29 CFR 778.115).

You choose the overtime rule yourself. The site does not guess your state, because state rules change and some workers are exempt or covered by a union contract.
