Weekly Overtime: The Standard Rule
The default rule in the United States is weekly: hours beyond 40 in a workweek are overtime, paid at 1.5 times your regular rate. Set the Weekly Overtime After field (40 by default), enter your shifts, and the tiles below the table show your regular hours, overtime hours, and, if you add an hourly rate, your total pay. Working 46 hours at $20 per hour shows 40 regular, 6 overtime, and $980 total (40 × $20 + 6 × $30).
Daily Overtime: The California-Style Rule
Several states, most prominently California, also count overtime per day: hours beyond 8 in a single workday are overtime even if the week stays under 40. Set Daily Overtime After to 8 to apply it. The calculator counts daily overtime first, then applies the weekly threshold to the remaining straight-time hours, so no hour is ever counted as overtime twice. Four 10-hour days, for example, shows 32 regular and 8 overtime hours even though the week totals just 40.
Note: this tool covers the common 1.5× rules. Some states add double-time (for example, beyond 12 hours in a day) and other special cases, so always check your state's rules or your employment agreement for the final word.
Frequently Asked Questions
How is overtime calculated?
Under the standard federal rule, hours over 40 in a workweek are paid at 1.5 times your regular rate. Enter your times and the calculator splits your total into regular and overtime hours automatically.
What about daily overtime, like in California?
Some states count hours over 8 in a single day as overtime, regardless of the weekly total. Set the Daily Overtime After field to 8 and the calculator applies the daily rule, then the weekly rule on the remaining hours, without counting any hour twice.
How much is time and a half?
Time and a half is 1.5 times your regular hourly rate. At $20 per hour, each overtime hour pays $30. Enter your rate and the calculator shows the total including overtime pay.
Is overtime calculated per week or per pay period?
Per workweek. Working 45 hours one week and 35 the next earns 5 hours of overtime, even though the two weeks average out to 40. The bi-weekly calculator applies this rule to each week separately.
