The calculator multiplies your hourly rate by the overtime multiplier (1.5x by default) to get the overtime rate. It then prices each tier separately: regular hours at the normal rate, overtime hours at the overtime rate, and double-time hours at twice the normal rate, adding all three for the weekly gross pay. The annual gross estimate is the weekly gross times 52. Everything runs before taxes, so the figures are gross pay estimates for planning, not take-home pay and not legal or payroll advice.
Overtime pay is the extra pay you earn for working beyond your standard hours. In the US, federal law requires most hourly (non-exempt) workers to be paid at least 1.5 times their regular rate, called time and a half, for every hour worked past 40 in a single workweek. Some contracts, holidays and states add steeper tiers such as double time (2x) for very long days or specific situations.
Enter your hourly rate, your regular hours, your overtime hours and the overtime multiplier (1.5x time and a half is the standard), plus any double-time hours at 2x. The calculator shows your overtime rate, the pay for each tier, your total weekly gross pay and an annual gross estimate. Results are gross pay estimates before taxes, not legal or payroll advice.
Overtime rate = hourly rate × multiplier. Regular pay = rate × regular hours. Overtime pay = overtime rate × overtime hours. Double-time pay = rate × 2 × double-time hours. Weekly gross pay = regular pay + overtime pay + double-time pay. Annual gross estimate = weekly gross × 52. The extra pay above the normal rate is called the premium: at 1.5x, the premium is the extra 50%.
At $18 an hour with 48 hours worked: the overtime rate is 18 × 1.5 = $27.00. Overtime hours are 48 - 40 = 8. Regular pay = 40 × 18 = $720.00. Overtime pay = 8 × 27 = $216.00. Weekly gross = $720 + $216 = $936.00. This is the classic single-tier overtime week, and it matches the federal 40-hour rule.
At $25 an hour with 38 regular hours, 4 overtime hours at 1.5x and 2 double-time hours: the overtime rate is 25 × 1.5 = $37.50 and the double-time rate is $50.00. Regular pay = 38 × 25 = $950.00. Overtime pay = 4 × 37.50 = $150.00. Double-time pay = 2 × 50 = $100.00. Weekly gross = $950 + $150 + $100 = $1,200.00. Pricing each tier separately and adding is the method every payroll uses.
Time and a half means 1.5 times your regular hourly rate. Multiply your hourly wage by 1.5: a $20 rate becomes $30 per overtime hour. The extra 50%, the half-time premium, is what compensates you for working beyond your normal schedule. It is the minimum federal overtime rate in the US for covered workers, and it is also the default in many contracts worldwide.
Time and a half (1.5x) is the standard overtime rate: every overtime hour pays your rate plus half again. Double time (2x) pays twice your rate and applies in rarer cases: California requires it after 12 hours in a single day or after the 8th hour on the seventh consecutive workday, and some union contracts, holiday rules and employers use it. Custom multipliers exist too, for example 2.5x for certain holiday shifts, which is why this calculator lets you set the overtime multiplier yourself.
Under the federal Fair Labor Standards Act (FLSA), non-exempt employees must be paid time and a half for hours beyond 40 in a fixed 7-day workweek; employers cannot average a 50-hour week with a 30-hour week to dodge overtime. Federal law sets no daily overtime cap, but states can go further: California requires 1.5x after 8 hours in a day and double time after 12, and whichever rule is more generous to the worker applies. State rules can only add protections, never subtract from the federal floor. In the UK there is no statutory overtime premium at all; it depends entirely on the employment contract.
The key question is whether you are non-exempt. Hourly workers almost always qualify. Salaried workers may or may not: it depends on job duties and pay level, not on being salaried. Managers, professionals and administrators above a salary threshold are typically exempt, meaning no overtime no matter how long the week runs. Non-exempt salaried workers are entitled to overtime; divide the weekly salary by standard hours to find the effective hourly rate. If you are unsure, your employer's HR department or your state's labor agency can clarify your classification.
No. Overtime income is taxed at the same marginal rate as regular income; there is no special overtime tax. What surprises people is withholding: a bigger weekly paycheck can push that week's pay into a higher withholding bracket, so the take-home from overtime can feel smaller than expected even though the tax rate on it is unchanged.
This calculator shows gross pay: the full amount before federal tax, state tax, Social Security and Medicare are withheld. Your actual paycheck will be lower. For the net figure, run the gross through a paycheck calculator with your tax details. And remember: the page multiplies the hours and rates you type; it does not decide which hours legally count as overtime in your state, so treat the result as a planning estimate, not legal advice.
Multiply overtime hours by your hourly rate, then by 1.5 for time and a half: overtime pay = hours × rate × 1.5. At $20 an hour, 8 overtime hours pay 8 × 20 × 1.5 = $240. Add regular pay (rate × regular hours) and any double-time pay for the weekly gross.
Time and a half is 1.5 times the regular hourly rate. A $20 wage becomes $30 for each overtime hour. It is the standard federal overtime rate in the US for hours beyond 40 in a workweek.
Time and a half (1.5x) is the standard federal overtime rate. Double time (2x) is required only in specific situations, most notably California's rule for working over 12 hours in a day or on the seventh consecutive workday. Most states do not legally mandate double time.
Most hourly workers qualify. Salaried employees earning under the FLSA threshold or failing the exempt duties test are also generally entitled to overtime. Exempt executive, administrative and professional workers do not get overtime regardless of hours.
Yes, many do. Salaried employees classified as non-exempt under the FLSA are entitled to overtime. Divide your weekly salary by your standard hours to find the effective hourly rate, then enter your regular, overtime and double-time hours as normal.
No. Overtime is taxed at the same marginal rate as regular income. A bigger paycheck can, however, push that week into a higher withholding bracket, which is why take-home overtime sometimes feels smaller than expected.
Yes. California requires time-and-a-half after 8 hours in a single workday or 40 hours in a week, and double time after 12 hours in a day or on the seventh consecutive workday. Federal law only requires 1.5x after 40 weekly hours.
A larger paycheck can land that week in a higher withholding bracket, so more tax is withheld from the overtime than you might expect. The tax RATE on overtime is the same as on regular pay; it is the withholding math that makes the take-home look smaller.
