Overtime calculator
Enter the hours you worked each day. See how many are overtime and what you earn.
Type hours as 8.5 or 8:30. Overtime counts on the days it falls.
How overtime is counted
Under federal law, covered employees get at least time and a half for hours over 40 in a workweek. Some states also pay overtime for long days. Hours already paid as daily overtime are not counted again toward the weekly total.
| Rules | Daily | Weekly | Other |
|---|---|---|---|
| Federal (FLSA) | None | Over 40 hours | Non-exempt employees |
| California | Over 8 hours, double time over 12 | Over 40 hours | Seventh consecutive day of the workweek |
| Alaska | Over 8 hours | Over 40 hours | Many listed exceptions |
| Nevada | Over 8 hours, if paid under 1.5× minimum wage | Over 40 hours | Four 10-hour days by agreement |
| Colorado | Over 12 hours | Over 40 hours | Also 12 consecutive hours |
What this calculator leaves out
It uses the general rules only. It does not handle exempt employees, alternative workweek schedules, industry orders or union contracts. See the methodology for the full list and sources.
Questions people ask
How is overtime pay calculated?
Multiply your regular hourly rate by 1.5, then by your overtime hours. At $20 an hour, 5 overtime hours pay $150, on top of regular pay for the first 40.
Does the federal government require daily overtime?
No. The federal rule counts hours over 40 in a workweek. Daily overtime comes from state law, as in California, Alaska, Nevada and Colorado.
What is a workweek?
A fixed, repeating period of 168 hours, seven days in a row. Employers choose when it starts. Set the week start in the calculator to match your pay stub. The Department of Labor has more.
