About Work Hours Calculator
The Work Hours Calculator answers one question fast: how many hours did I actually work? Enter your clock-in time, clock-out time, and the length of your unpaid lunch in minutes, and it returns your total worked time in both hours-and-minutes and decimal hours. Add an hourly rate and it also estimates your gross pay for the shift, all laid out in a clean stat grid so you can read the whole result at a glance.
It handles the cases a plain clock-difference misses. Flip on the overnight shift toggle when you clock out the next day and it spans midnight correctly instead of returning a negative number. Your unpaid break is subtracted from the span, so "work hours with lunch included" is the default behavior, not an afterthought. Working out a weekly total? Run each day's shift through the calculator and add the decimal hours together, since decimal hours are the payroll-friendly format that makes that addition simple.
Think of it as a free, no-signup alternative to the time-card and work-hours calculators you might find on sites like Calculator Soup, but with pay estimation built in and nothing to install. It suits hourly workers checking a paycheck, managers sanity-checking a posted schedule, and anyone logging billable time.
Everything runs entirely in your browser. Your clock times, break, hourly rate, and pay are never uploaded, saved, or sent to a server, so your hours stay private on your own device.
Frequently asked questions
- Is the Work Hours Calculator free to use?
- Yes, it is 100% free with no signup, account, or usage limits. Enter your times as often as you like.
- Is my data uploaded or stored anywhere?
- No. All calculations happen locally in your browser. Your clock times, break, hourly rate, and pay are never uploaded, tracked, or saved to any server.
- How do I figure out how many hours I worked?
- Enter your clock-in time, your clock-out time, and any unpaid break in minutes. The calculator subtracts the break and shows your total in hours and minutes plus decimal hours, so you get the answer without doing the math by hand.
- How do I calculate hours for an overnight shift?
- Turn on the 'Overnight shift' checkbox. The calculator then treats the clock-out time as the next day and adds 24 hours to the span before subtracting your break, so a shift that crosses midnight totals correctly.
- Does this calculator include lunch breaks?
- Yes. Put your unpaid lunch in the break field in minutes and it is subtracted from the shift, so the total reflects paid time only. Whether you call it lunch or a break, the math is the same.
- How is the unpaid break handled?
- The break, entered in minutes, is subtracted from the shift span so only paid time is counted. If the break is as long as or longer than the shift, the tool shows a helpful error instead of a negative result.
- How do I calculate my weekly work hours?
- Calculate each day's shift one at a time, then add the decimal-hour results together for the week's total. Using decimal hours (8.50 rather than 8h 30m) keeps that addition clean and matches how payroll adds time.
- Can I use this to check hours from my work schedule?
- Yes. Plug the scheduled start and end times, plus any lunch, into the calculator to see how many paid hours a scheduled shift is worth. It is handy for comparing a posted schedule against what you were actually paid.
- Is this like the Calculator Soup work hours calculator?
- It does the same core job of turning clock-in and clock-out times into total hours, and adds an optional hourly-rate field for gross pay. It is free, needs no signup, and runs entirely in your browser.
- How is gross pay calculated?
- Gross pay equals your total paid time in decimal hours multiplied by the hourly rate you enter. For example, 8.00 hours at $20.00 is $160.00. The hourly rate is optional; leave it blank to see hours only.
- What are decimal hours versus hours and minutes?
- Decimal hours express your worked time as a single number for payroll math (for example, 8h 30m is 8.50 hours). The tool shows both the hours-and-minutes format and the decimal value.
