Is overtime always time-and-a-half?

Under federal law, yes: covered, non-exempt employees earn at least 1.5 times their regular rate for hours over 40 in a workweek. Some states add a higher multiplier in specific situations, such as double time after 12 hours in a day in California, but 1.5x is the federal baseline.

Does overtime start after 8 hours in a day?

Not under federal law. The FLSA measures overtime by the workweek, not the day, so 40 hours is the federal trigger. A minority of states — including California, Alaska, Nevada, and Colorado — require daily overtime after 8 or 12 hours regardless of the weekly total.

Can my employer average two weeks together to avoid overtime?

No. The workweek is a fixed, recurring 168-hour period, and overtime is calculated week by week. An employer cannot average a 30-hour week and a 50-hour week to claim you worked 40 each; the 50-hour week owes 10 hours of overtime on its own.

How Overtime Pay Actually Works — Time-and-a-Half, the Workweek & Daily OT

The federal baseline: 40 hours, then time-and-a-half

The Fair Labor Standards Act (FLSA) is the federal law that sets the floor for overtime. The rule is short: a covered, non-exempt employee who works more than 40 hours in a single workweek must be paid at least one and one-half times their regular rate of pay for every hour past 40. That is the entire federal overtime requirement. There is no federal rule about working long days, working weekends, or working holidays — only the weekly total matters.

Two words in that rule do a lot of work. "Non-exempt" means the overtime protection only applies to employees who are not exempt from it — a distinction covered in the exempt vs. non-exempt guide. And "regular rate" is not always your stated hourly wage; bonuses and commissions can raise it, which the regular-rate guide explains.

The workweek is fixed — and that protects you

Overtime is measured over a "workweek," which the FLSA defines as any fixed, regularly recurring period of 168 hours — seven consecutive 24-hour days. An employer picks when the workweek starts (say, Sunday at midnight), but once chosen it cannot shift week to week to dodge overtime.

This is why an employer cannot average two weeks together. If you work 30 hours one week and 50 the next, you are owed 10 hours of overtime for the 50-hour week. Averaging the two to claim "40 each" is not allowed under the FLSA.

Where states break the pattern: daily overtime

The single biggest reason a generic overtime calculator gives the wrong answer is daily overtime. A minority of states require overtime based on hours worked in a day, not just the week:

California — 1.5x after 8 hours in a day, 2x after 12 hours, plus rules for the seventh consecutive day. California overtime calculator.
Alaska — 1.5x after 8 hours in a day or 40 in a week, whichever gives the employee more. Alaska overtime calculator.
Nevada and Colorado — daily overtime under specific conditions tied to the state minimum wage or industry.

In a daily-overtime state, a person who works four 10-hour days is owed 8 hours of overtime even though the week totaled only 40 hours. A weekly-only calculator would show zero. That gap is real money, and it is exactly why this site is organized by state first.

Weekend and holiday pay is usually a myth

There is a widespread belief that Saturday, Sunday, and holiday work automatically pays extra. Under federal law it does not. Unless a state law, a union contract, or a company policy says otherwise, a holiday worked is paid at the normal rate, and it only becomes overtime if it pushes the weekly total past 40. The main exceptions are public-works and prevailing-wage jobs in some states, where premium days are written into the wage determination.

What to do with this

Start by finding your state, because the state answer is the one that governs. Pick your state on the states directory, then open its overtime calculator. Enter your real hours — including the daily breakdown if your state has daily overtime — and the tool shows the arithmetic line by line, with a link to the controlling statute. If the result looks wrong, the paycheck guide walks through the next steps.
