Quick answer
Overtime pay is your regular hourly rate × 1.5 × overtime hours; double time is rate × 2 × hours. Under the federal Fair Labor Standards Act, non-exempt employees earn time-and-a-half for hours over 40 in a workweek. At $22 an hour, 8 overtime hours pay $22 × 1.5 × 8 = $264, so a 48-hour week grosses $1,144.
What the Overtime Pay calculator does
This calculator adds up regular pay, time-and-a-half and double time for one week and shows your total gross pay and effective hourly rate across all hours worked. Enter the hours from your timesheet already split into the three pay rates.
Federal law (the FLSA) only requires overtime after 40 hours in a workweek and has no daily overtime or double-time rule. Several states go further, most notably California, and some employers pay double time for holidays or Sundays by contract. Check your state's labor department or your union agreement for the rules that apply to you.
The result is gross pay before taxes and deductions. To see what lands in your bank account, run the gross figure through the paycheck calculator. To turn a typical week into an annual figure, use the hourly to salary calculator.
The formula
Gross pay = R × H(reg) + R × 1.5 × H(ot) + R × 2 × H(dt)
| Symbol | Meaning | Unit |
|---|---|---|
| R | Regular hourly rate of pay | $ per hour |
| H(reg) | Hours paid at the regular rate (normally up to 40 a week) | hours |
| H(ot) | Hours paid at time-and-a-half | hours |
| H(dt) | Hours paid at double time | hours |
The 1.5× rule comes from the Fair Labor Standards Act, enforced by the US Department of Labor's Wage and Hour Division. Effective hourly rate = gross pay ÷ total hours.
Under the FLSA the "regular rate" must include most non-discretionary bonuses, commissions and shift differentials, not just the base wage, so overtime can be worth more than 1.5× your base rate. If you earn a bonus tied to performance or attendance, your true overtime rate is higher than this calculator shows.
Worked examples
Standard 48-hour week
A warehouse worker on $22 an hour works 40 regular hours and 8 overtime hours.
Inputs
- Regular hourly rate22 $
- Regular hours40 hrs
- Overtime hours (1.5×)8 hrs
- Double-time hours (2×)0 hrs
Result
- Total gross pay$1,144.00
- Regular pay$880.00
- Overtime pay$264.00
- Double-time pay$0.00
- Effective hourly rate$23.83
Gross pay is $1,144, with $264 from overtime. Each overtime hour is worth $33, so the effective rate for the week rises to $23.83.
Heavy overtime at a lower wage
A retail or care worker on $18 an hour picks up 12 extra hours in a 52-hour week.
Inputs
- Regular hourly rate18 $
- Regular hours40 hrs
- Overtime hours (1.5×)12 hrs
- Double-time hours (2×)0 hrs
Result
- Total gross pay$1,044.00
- Regular pay$720.00
- Overtime pay$324.00
- Double-time pay$0.00
- Effective hourly rate$20.08
Overtime adds $324 to $720 of regular pay, a 45% boost to the week's gross of $1,044. Withholding on this paycheck will also be higher than usual.
California week with a long shift
A worker on $25 an hour in California has 40 regular hours, 6 hours over 8 in a day, and 2 hours past the 12th hour of one shift.
Inputs
- Regular hourly rate25 $
- Regular hours40 hrs
- Overtime hours (1.5×)6 hrs
- Double-time hours (2×)2 hrs
Result
- Total gross pay$1,325.00
- Regular pay$1,000.00
- Overtime pay$225.00
- Double-time pay$100.00
- Effective hourly rate$27.60
The 2 double-time hours add $100 and the 6 overtime hours $225, for $1,325 gross. Under federal rules alone those last 2 hours would have been paid at 1.5×, $25 less.
Federal versus California overtime rules
Most states follow the federal 40-hour weekly rule. California is the best-known exception; a few other states also have daily overtime rules, so check with your state labor agency.
| Situation | Federal (FLSA) | California |
|---|---|---|
| Over 40 hours in a workweek | 1.5× | 1.5× |
| Over 8 hours in a workday | No requirement | 1.5× |
| Over 12 hours in a workday | No requirement | 2× |
| 7th consecutive workday, first 8 hours | No requirement | 1.5× |
| 7th consecutive workday, beyond 8 hours | No requirement | 2× |
| Holidays and weekends | No requirement (pay by contract or policy) | No requirement unless hours rules above are met |
Is overtime taxed more
Overtime is taxed as ordinary wages. It is not taxed at a special higher rate, but a paycheck containing overtime can have more tax withheld than you expect, because payroll systems annualize each paycheck: a big week looks like a bigger salary. Any over-withholding comes back when you file your return.
For tax years 2025 through 2028, federal law allows eligible workers to deduct the premium part of qualified overtime pay (the extra half in time-and-a-half) from income for federal income tax, up to an annual cap and subject to income phase-outs. Social Security, Medicare and most state income taxes still apply. Check current IRS guidance, as the details determine whether your overtime qualifies. The payroll tax calculator shows the FICA on your extra earnings.
Who is not entitled to overtime
- Exempt salaried employees: executive, administrative and professional staff paid a salary above the federal threshold and meeting the job-duties tests. Job title alone does not make someone exempt.
- Certain occupations: outside sales staff and some computer professionals, among others, have specific exemptions.
- Independent contractors: overtime law covers employees only. Misclassification is common, and the Department of Labor looks at the real working relationship, not the contract label.
If you think you are owed unpaid overtime, the Department of Labor's Wage and Hour Division and state labor agencies take complaints free of charge.

Frequently asked questions
How do I calculate time and a half?
Multiply your hourly rate by 1.5 to get the overtime rate, then by the overtime hours. At $20 an hour, time-and-a-half is $30, and 5 hours earn $150.
Is overtime calculated daily or weekly?
Federally it is weekly: hours over 40 in a fixed seven-day workweek. California and some other states add daily overtime on top.
Can my employer average hours over two weeks?
No, not for most employees under the FLSA. Each workweek stands alone, so 45 hours one week and 35 the next still earns 5 overtime hours. Some hospital and public-sector employees have special arrangements.
Do salaried employees get overtime?
Salaried employees who are non-exempt, because their salary is below the threshold or their duties don't qualify, are entitled to overtime. Their hourly rate is the weekly salary divided by the hours it is meant to cover.
Do paid holidays or sick days count toward 40 hours?
Not under federal law: only hours actually worked count. Your employer's policy or union contract may be more generous.
