How to use the Overtime Calculator
- Enter your regular hourly rate.
- Enter the total hours you worked this week and when overtime starts (40 hours under US federal law).
- Read your regular pay, overtime pay and total gross pay. Add any double-time hours separately.
- Optional: enter a weekly gross-pay target to solve for additional hours.
How overtime pay is calculated
Under the US Fair Labor Standards Act (FLSA), non-exempt employees earn at least 1.5 times their regular rate for every hour over 40 in a workweek. With a $20 rate and 48 hours: regular pay = 40 × $20 = $800; overtime = 8 × $30 = $240; total = $1,040.
Time and a half vs double time
- Time and a half = rate × 1.5. At $18/hour that is $27/hour.
- Double time = rate × 2. Federal law does not require it, but some states (for example California, for hours over 12 in a day) and many union contracts do.
Daily overtime and state rules
Most states follow the weekly 40-hour rule. A few, including California, Alaska, Nevada and Colorado, also require overtime after a set number of hours per day. Outside the US, overtime rules are set by national law or employment contracts. Salaried “exempt” employees are generally not entitled to overtime.
