45 of the 51 US jurisdictions here — all fifty states plus the District of Columbia — run on the same rule: time and a half after 40 hours in a workweek, and nothing extra for a long day. The other 6 do more. They count hours inside a single day, or pay a second premium tier, or pay for the seventh day straight, so they are listed first. Open a state for its thresholds, the statute they come from, and a calculator already loaded with them.

In these 6, a week that never passes 40 hours can still owe premium pay — and a week that does pass 40 is not always priced the way a flat tracker prices it.
| state | overtime starts | what is different |
|---|---|---|
| Alaska | 8h/day · 40h/week | daily overtime after 8 hours (employers with four or more employees) · no hour counted twice |
| California | 8h/day · 40h/week | daily overtime after 8 hours · double time after 12 hours in a day · premium on the seventh consecutive day · no hour counted twice |
| Colorado | 12h/day · 40h/week | daily overtime after 12 hours · the greater of daily or weekly, never both |
| Kentucky | 40h/week | premium on the seventh consecutive day |
| Nevada | 8h/day · 40h/week | daily overtime after 8 hours (employees paid under 1.5× the state minimum wage) · no hour counted twice |
| Oregon | 10h/day · 40h/week | daily overtime after 10 hours (manufacturing and cannery work) · the greater of daily or weekly, never both |
One threshold, one multiplier: hours past 40 in a workweek pay one and a half times the regular rate. Twelve-hour days, six-day stretches and split shifts change nothing on their own — only the weekly total counts. Each page carries the state’s own wording, the quirks worth knowing, and the same calculator.
Where a state sets a rule the federal one does not, the state rule applies to the work done in that state — the federal 40-hour floor never goes away, it is simply the lower of the two. That is why California’s daily thresholds and the federal weekly one both appear on the California page.
The threshold is only half of what decides your pay. The other half is the workweek: a fixed, recurring 168-hour period your employer designates, which can start on any day at any hour and is usually printed on your stub. It decides which hours land past 40, and it is not always the calendar week. A seven-day stretch that straddles two workweeks can owe nothing at all.
Working in Canada? The provinces run on different numbers — 44 hours in Ontario, 8 and 12 in British Columbia. For a side-by-side of every jurisdiction, use the threshold reference table, or start from the main overtime calculator.
Checking one week by hand is fine. Checking every week is what the app is for — it keeps your hours, applies your state’s rules as you punch, and tells you what the stub should say before it arrives.
Every figure on this page traces to the statute or agency page above. If one is out of date, tell us — corrections ship the same week.
Overtally computes what you should be paid before taxes. It does not calculate take-home pay, withholding or deductions, and it is not legal advice — it is your own record and your own estimate.
