Overtime Calculator
Enter your hourly rate and the hours you worked this week to see your regular pay, overtime pay and total. Overtime is usually paid at 1.5 times your rate ('time and a half') for hours over 40 a week; some states and contracts also pay double time.

Worked example
At $20 an hour, 46 hours in one week is 40 regular hours and 6 overtime hours. Regular pay is 40 × $20 = $800. The overtime rate is $20 × 1.5 = $30, so overtime pay is 6 × $30 = $180. Total pay for the week is $800 + $180 = $980, before tax.
Total pay = regular hours × rate + overtime hours × rate × multiplier
How overtime is calculated
Under the federal Fair Labor Standards Act, employees who are covered and not exempt must get at least one and a half times their regular rate of pay for hours worked over 40 in a workweek. The workweek is a fixed period of seven consecutive 24-hour days that your employer sets, and each week is counted on its own: hours can't be averaged across two or more weeks. Federal law doesn't require extra pay for weekends or holidays as such, only for hours over 40.
Gross pay here is before tax and other deductions. The calculator uses your hourly rate as the regular rate; bonuses and some other pay can change the regular rate in real payroll.
State rules: daily overtime and double time
Some states go further than federal law. California, for example, requires 1.5 times pay for hours over 8 in a workday and double time for hours over 12 in a workday, with extra rules for the seventh consecutive day. Tick Daily overtime above to apply a daily threshold (for example four 10-hour days give 8 overtime hours), and check your state's labor department for the rules that apply to you.

FAQ
How do I calculate time and a half?
Multiply your regular hourly rate by 1.5 to get the overtime rate, then multiply that by your overtime hours. For example, at $20 an hour the overtime rate is $30, so 6 overtime hours pay $180. Add this to 40 regular hours at $20, or $800, for a weekly total of $980.
When does overtime start?
Under the federal Fair Labor Standards Act, overtime starts after 40 hours worked in a workweek for non-exempt employees. Federal law does not require overtime for working more than 8 hours in a single day, but some states, including California, do. Your employer's policy or contract may also be more generous.
Is double time required by law?
Not under federal law. Double time is mainly required by state law in a few places; California, for example, requires it for hours over 12 in a day. Otherwise it comes from employer policy, union agreements or holiday pay rules. Enter 2 as the multiplier in the calculator if it applies to you.
