Weekly Hours and Overtime Pay
Under the federal Fair Labor Standards Act, overtime is every hour worked over 40 in a workweek, paid at no less than 1.5 times your regular rate. A 45-hour week at $20 an hour is $800 of regular pay plus 50 of overtime, $950 gross. Enter each day's start, end and unpaid break above and the calculator totals the week and splits regular from overtime pay.
Weekly Gross Pay at Common Hours and Rates

Federal vs California Overtime Rules
Federal law only looks at the week. A handful of states also look at the day, and California has the best known daily rules.
| Rule | Federal (FLSA) | California |
|---|---|---|
| Weekly overtime | Over 40 hours at 1.5x | Over 40 hours at 1.5x |
| Daily overtime | None | Over 8 hours in a day at 1.5x |
| Double time | Not required | Over 12 hours in a day at 2x |
| 7th consecutive day | No special rule | First 8 hours at 1.5x, beyond 8 at 2x |
The same 40 hours can pay differently. At $20 an hour:
| Schedule | Total | OT federal | OT daily + weekly | Pay federal | Pay daily + weekly |
|---|---|---|---|---|---|
| 5 days × 8 h | 40 h | 0 h | 0 h | $800 | $800 |
| 4 days × 10 h | 40 h | 0 h | 8 h | $800 | $880 |
| 5 days × 9 h | 45 h | 5 h | 5 h | $950 | $950 |
| 6 days × 8 h | 48 h | 8 h | 8 h | ,040 | ,040 |
Pick "40h / week (US)" for the federal rule or "8h / day + 40h / week (CA)" for the daily one. The calculator does not apply California's 12-hour double time or 7th-day rule automatically, so set the OT rate by hand if those apply to you.
Who Gets Overtime and What Counts as Hours
Exempt or non-exempt
Most hourly workers are covered. Salaried employees can be exempt from overtime only if they do executive, administrative or professional work and earn at least $684 a week ($35,568 a year), the salary level the Department of Labor enforces in 2026. Job title alone does not make anyone exempt.
Hours that count toward 40
- Short rest breaks of about 5 to 20 minutes count as work time. A meal break of usually 30 minutes or more, fully off duty, does not.
- Paid holidays, vacation and sick days are paid but not worked, so under the FLSA they do not count toward the 40.
- Each workweek stands alone. An employer cannot average a 50-hour week and a 30-hour week to avoid overtime.
Tax on overtime, 2025 to 2028
Overtime is taxed as normal wages, but for tax years 2025 to 2028 you can deduct the premium part of qualified overtime (the extra half in time-and-a-half) from federal taxable income, up to 2,500 a year, or $25,000 for a joint return. The deduction shrinks above 50,000 of income ($300,000 joint). Social Security and Medicare tax still apply. See the Overtime Pay Calculator and the Paycheck Calculator for take-home figures.
Method and sources. Daily hours = end minus start (plus 24 hours when the shift crosses midnight) minus the unpaid break. Weekly overtime = hours over the chosen weekly threshold; the daily mode adds hours over 8 in each day, then any remaining regular hours over 40. Rules: Fair Labor Standards Act, 29 U.S.C. 207, and U.S. Department of Labor guidance on breaks and hours worked (29 CFR 785.18 and 785.19); exempt salary level from the Department of Labor's 2019 rule, restored in 2026; California Labor Code section 510; overtime deduction from the IRS summary of the One Big Beautiful Bill Act. Gross pay only, not legal advice.
Work Hours Questions
Enter your start and end time for each working day. The calculator subtracts your break duration (in minutes) from the gross time for each day, then sums all net daily hours. Formula: daily net hours = (end time − start time) − break minutes. Sum all 7 days for the weekly total. This calculator does it automatically as you type: no need to click Calculate after each change.
Overtime depends on your setting. With "40h / week" (US standard): any hours above 40 total for the week are overtime. With "8h / day + 40h / week" (California-style): each day's hours above 8 are overtime, and any regular hours beyond 40 in the week are overtime too, without counting the same hour twice. Formula: overtime pay = overtime hours × hourly rate × OT multiplier (default 1.5x). Regular pay = regular hours × hourly rate. Gross = regular pay + overtime pay. Select "No overtime" if your employer pays a flat rate regardless of hours.
United States: 40 hours per week (FLSA standard). United Kingdom: 37.5 hours per week typical, 48h legal maximum. France: 35 hours per week (the legal working week; hours above it are paid as overtime). Germany: 40 hours typical, 48h legal max. Australia: 38 hours per week ordinary hours. Japan: 40 hours per week (legal). China: 40 hours per week (legal). Most EU countries follow the Working Time Directive: maximum 48h/week averaged over 17 weeks. The US does not have a maximum hour limit for most workers, only an overtime premium requirement.
Unpaid breaks (lunch, personal time away from work) should be deducted from your work hours. Paid breaks should not be deducted. Federal law does not require employers to give breaks, but when they offer short rest breaks of about 5 to 20 minutes, the FLSA treats them as paid work time. Meal periods of usually 30 minutes or more, where you are fully relieved of duties, can be unpaid. UK employees have the right to one 20-minute rest break if they work more than 6 hours a day. Enter your unpaid break time in the "Break" column; the calculator subtracts it from each day's gross hours.
Gross pay is your total earnings before any deductions. Net pay (take-home pay) is what remains after deductions including: federal income tax, state income tax (US), Social Security (6.2%), Medicare (1.45%), health insurance premiums, 401k/pension contributions, and any other voluntary deductions. This calculator shows gross pay only. To estimate your take-home pay, use our Paycheck Calculator, which applies the actual 2026 US tax brackets and FICA rates to your gross hourly wage and weekly hours.
If your shift runs past midnight (e.g., 10:00 PM to 6:00 AM), enter 22:00 as start and 06:00 as end. The calculator automatically detects when end time is earlier than start time and adds 24 hours to the end time, giving the correct 8-hour duration. This works for any overnight shift. For shifts spanning multiple calendar days, split the hours across the relevant days manually.
A standard US full-time job = 40 hours/week × 52 weeks = 2,080 hours per year. After typical deductions: subtract 11 federal holidays (88 hours) and 10 vacation days (80 hours) = approximately 1,912 productive hours per year. Annual salary to hourly rate: divide by 2,080 (before holiday/vacation adjustments). Example: $52,000 salary ÷ 2,080 = $25.00/hour. Or use 2,000 as a round number for quick estimates. UK full-time = 37.5h × 52 = 1,950 hours/year before leave deductions.
Double time is pay at 2× the regular hourly rate. In California, double time applies for hours worked over 12 in a single day, and for hours over 8 on the 7th consecutive day of work in a workweek (the first 8 hours that day are paid at 1.5×). Some union contracts require double time on holidays or Sundays. Federal law (FLSA) only requires time-and-a-half (1.5×) for hours over 40 per week: double time is not federally required. Select "2x (double time)" in the OT rate dropdown if your employer pays double time on all overtime hours.
Divide your annual salary by the number of hours you work per year. For a standard 40h/week US employee: hourly = annual salary ÷ 2,080. Examples: $50,000 ÷ 2,080 = $24.04/hour. $75,000 ÷ 2,080 = $36.06/hour. $100,000 ÷ 2,080 = $48.08/hour. For a quick estimate, divide by 2,000. For a UK employee at 37.5h/week: divide by 1,950. If you work part-time or variable hours, multiply your actual weekly hours by 52 for a more accurate denominator.
Best practice: record start time, end time, and break duration at the end of each shift, not at the end of the week from memory. Keep records for at least 3 years (FLSA requirement in the US). Include: employee name, workweek start/end dates, hours worked each day, total hours each week, pay rate, total straight-time earnings, overtime earnings, any deductions. If your employer pays by the hour, they are legally required to keep these records. As an employee, keeping your own records protects you in wage disputes. Screenshot or print this calculator's results weekly for your personal records.
Not under federal law. The FLSA counts hours actually worked, so a paid holiday, vacation day or sick day adds to your pay but not to the 40-hour total. If you are paid for a holiday Monday and then work 42 hours Tuesday to Saturday, you have 2 overtime hours, not 10. Some employers and union contracts count paid time off anyway, which is allowed because it is more generous.
No. Overtime is worked out for each workweek on its own, a fixed period of 168 hours in a row that the employer sets in advance. A 50-hour week followed by a 30-hour week means 10 overtime hours, even though the two weeks average 40, and even if you are paid every two weeks. A few public sector and hospital arrangements are the exception.
No. Overtime is ordinary wages and is withheld the same way, though a bigger paycheck can land partly in a higher bracket. For 2025 to 2028 there is a new federal deduction for the premium part of qualified overtime, up to $12,500 a year ($25,000 on a joint return), reduced once income passes $150,000 ($300,000 joint). It lowers income tax only; Social Security and Medicare are still taken out.
