Worked example: why your state matters
Four 12-hour days at $24 an hour — 48 hours in the week:
- Federal rule only: 40 regular hours + 8 overtime hours = $960 + $288 = $1,248.
- California rules: each day is 8 regular + 4 overtime hours, so the week is 32 regular + 16 overtime = $768 + $576 = $1,344.
Same hours, same rate — a $96 difference. The federal rule is the floor, not the ceiling; where your state is stricter, your employer must follow the rule that pays you more.
How overtime works, in plain English
The federal rule (FLSA)
The US Department of Labor's Fair Labor Standards Act requires overtime at 1.5× your regular rate for hours over 40 in one workweek. It has no daily limit.
State rules this calculator applies
- California: 1.5× after 8 hours in a day, 2× after 12 hours in a day. On the 7th day worked in a row in the same week, the first 8 hours are at 1.5× and anything beyond at 2×. The weekly 40-hour rule also applies to hours not already paid at a premium.
- Alaska: 1.5× after 8 hours in a day, plus the weekly 40-hour rule.
- Colorado: 1.5× after 12 hours in a day (or 12 consecutive hours), plus the weekly 40-hour rule.
- Nevada: if your rate is under 1.5× the state minimum wage (under $18.00 an hour while the minimum wage is $12.00), 1.5× after 8 hours in a day, plus the weekly rule.
- All other states: the federal weekly rule.
No hour is ever counted twice: daily overtime is worked out first, and the weekly rule is then applied only to the hours still paid at the regular rate.

Frequently asked questions
What is the federal overtime rule?
Under the Fair Labor Standards Act (FLSA), most US workers must be paid at least 1.5 times their regular rate for every hour worked over 40 in a single workweek. There is no federal daily overtime rule.
Which states have daily overtime?
California pays overtime after 8 hours in a day and double time after 12, plus a special rule for the 7th day worked in a row. Alaska pays overtime after 8 hours in a day. Colorado pays overtime after 12 hours in a day. Nevada pays daily overtime to workers earning less than 1.5 times the state minimum wage. This calculator applies each state's rule automatically.
Can daily and weekly overtime be paid on the same hour twice?
No — that is called pyramiding, and the law does not require it. This calculator counts daily overtime first, then applies the weekly 40-hour rule only to the hours that are still paid at the regular rate, which is the standard payroll method.
How much is overtime pay?
Overtime pay is 1.5 times your normal hourly rate for each overtime hour. Double time, where it applies, is 2 times your normal rate. At $20 an hour, an overtime hour pays $30 and a double-time hour pays $40.
