Overtime Calculator

Time and a half, double time, daily state rules — enter your hours and rate, pick the rules that apply, and see exactly how your overtime pay breaks down.

How do you want to enter hours?

Decimal hours per day (e.g. 8.5). Daily and 7th-day state rules need per-day entry.

State daily overtime rules

Most states follow the federal weekly-only standard. These four add daily thresholds — all built into the calculator's presets:

StateDaily OT (1.5×)Daily 2×Weekly
CaliforniaOver 8 h (+ 7th day)Over 12 h (+ 7th day > 8 h)40 h
AlaskaOver 8 h—40 h
NevadaOver 8 h (lower-wage employees)—40 h
ColoradoOver 12 h (or 12 consecutive)—40 h
All other states——40 h (federal)

Nevada's daily rule applies only to employees earning less than 1.5× the state minimum wage; Colorado also triggers overtime after 12 consecutive hours regardless of the workday. Rules change — verify with your state labor agency for an active dispute.

Frequently asked questions

How is overtime calculated?
Federally, overtime is 1.5× your regular rate for every hour beyond 40 in a workweek. A $20/hour employee working 46 hours earns 40 × $20 + 6 × $30 = $980. Some states add daily thresholds — the calculator applies the right split when you choose your state.
What is time and a half for $18 an hour?
Time and a half for $18/hour is $27.00/hour. The shortcut: add half the rate to itself ($18 + $9). Ten overtime hours at $18 base pay $270 instead of $180.
When is overtime double time?
Federal law never requires double time — it comes from state law or your employer’s policy. California requires 2× pay after 12 hours in a workday, and after 8 hours on the seventh consecutive workday of a workweek.
How does California overtime differ from federal?
California adds daily rules on top of the weekly 40: over 8 hours in a day earns 1.5×, over 12 earns 2×, and the 7th consecutive workday starts at 1.5× with 2× after 8 hours. A 4 × 10-hour schedule has zero federal overtime but 8 daily OT hours in California. Full details in the California overtime guide.
Who is exempt from overtime?
Salaried executive, administrative and professional employees meeting both the duties tests and the federal salary threshold are exempt, along with certain computer and outside-sales roles. Job titles alone don’t decide it — misclassification is a common wage claim. When in doubt, check the DOL fact sheets or your state labor agency.
Is unused PTO or a holiday counted toward overtime?
No — only hours actually worked count toward the 40-hour trigger. A week with 8 holiday hours plus 36 worked hours pays no federal overtime, because worked time is 36. Employer policies can be more generous.
