Work Hours Calculator

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" (California-style): each day's hours above 8 are overtime, regardless of weekly total. 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 (legal maximum for standard contract). 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 (short rest breaks of 5–20 minutes in the US, which employers must pay for) should not be deducted. In the US, the FLSA requires employers to pay for short breaks but not for meal periods of 30+ minutes where the employee is fully relieved of duties. 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 the first 8 hours on the 7th consecutive day of work in a workweek. 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.
