Hours Worked Calculator

Calculate the hours you worked in a single day from your clock-in time, clock-out time, and the length of any unpaid break. Built for hourly workers, freelancers tracking billable time, shift workers logging weekly timesheets, and small-business owners checking payroll before it goes out.

Last Updated: June 2026

Who this calculator helps

  • Hourly workers logging a daily timesheet for payroll.
  • Freelancers and consultants converting tracked time into billable decimal hours.
  • Restaurant, retail, and healthcare shift workers totaling split shifts or night shifts.
  • Small-business owners spot-checking employee submissions before payroll runs.
  • Anyone testing what a different shift pattern (start later, longer break) would do to their paid hours.

Hours worked

8h 0m

8.00 decimal hours

All calculations are estimates based on average platform fees. Real profits may vary depending on category, ads, and shipping.

How to use this calculator

  1. Enter your numbers in each field above โ€” the calculator updates instantly as you type, so there's nothing to submit.
  2. Use your real figures when you have them, or sensible estimates while you're planning. If a field doesn't apply, leave it at zero.
  3. Compare the results, then change one input at a time to see how each lever (price, cost, fees, volume) moves the outcome.

When to use this calculator

  • You finished a single shift and need exact paid hours.
  • You're filling in a timesheet that expects decimal hours instead of hours and minutes.
  • You want to verify a paycheck or invoice โ€” multiply the decimal hours by your rate and compare to what you were paid.
  • You're planning your week and want to see whether adding or removing a break changes your total enough to matter.

Formula

Hours worked = (Clock-out โˆ’ Clock-in) โˆ’ Break minutes

Worked example

Clock in 09:00, clock out 17:30, 30-minute break.

  1. Raw duration = 8h 30m = 510 minutes
  2. Subtract 30-minute break: 510 โˆ’ 30 = 480 minutes
  3. Convert: 480 รท 60 = 8 hours

Answer: 8h 0m

More worked examples

Restaurant double: 11:00โ€“14:30 (no break), then 17:00โ€“22:00 (30-minute unpaid break in the evening shift). Calculate them as two separate entries and add.

  1. Lunch shift: 14:30 โˆ’ 11:00 = 3h 30m = 3.50 hours (no break).
  2. Dinner shift: 22:00 โˆ’ 17:00 = 5h 0m = 300 min, minus 30 min break = 270 min = 4.50 hours.
  3. Day total: 3.50 + 4.50 = 8.00 hours

Answer: 8 hours total across both shifts

Night shift: clock in 22:00, clock out 06:00 the next morning, 45-minute unpaid break.

  1. Raw duration: 06:00 + 24:00 โˆ’ 22:00 = 8h = 480 minutes.
  2. Subtract 45-minute break: 480 โˆ’ 45 = 435 minutes.
  3. Convert: 435 รท 60 = 7.25 hours = 7h 15m

Answer: 7h 15m (7.25 hours)

Short shift with no break: clock in 13:00, clock out 17:15.

  1. Raw duration: 17:15 โˆ’ 13:00 = 4h 15m = 255 minutes.
  2. Break: 0 minutes.
  3. Paid: 255 รท 60 = 4.25 hours

Answer: 4h 15m (4.25 hours)

How it works

The calculator works out the elapsed time between clock-in and clock-out, then subtracts the unpaid break in minutes to give you net hours worked.

If the clock-out time is earlier than the clock-in time, the day is treated as crossing midnight and 24 hours is added โ€” useful for night shifts and late hospitality work.

The result is shown in both hours and minutes (8h 30m) and as a decimal (8.50 hours). Most payroll systems, project trackers, and invoicing tools expect decimal hours, so that's the figure to copy into a timesheet or invoice line.

Only unpaid breaks should be subtracted. If your employer pays for a short rest break or coffee break, leave it out of the break field so the time still counts towards your paid total.

Expert tips

  • To go straight from hours to estimated gross pay, multiply the decimal-hours result by your hourly rate. For a yearly view, run the result through the Hourly to Salary calculator on this site.
  • Most jurisdictions require a meal break only after a certain shift length (often 5โ€“6 hours). Check your local rules before assuming you owe time off the clock.
  • If overtime kicks in past 40 hours per week or 8 hours per day, calculate regular and overtime hours separately and apply each at its rate.
  • Round consistently โ€” most employers round to the nearest minute or to a fixed interval (such as 5 or 15 minutes). Use the same rounding rule every day to stay fair.
  • Save your decimal-hours total in a weekly tracker so you can quickly add them up at the end of the pay period.

How to interpret your results

  • Dollar values are shown per sale, per order, or per item unless a result is explicitly labelled monthly, weekly, or daily.
  • Percentages (margin, ROI, conversion rate) are easier to compare across products and price points than raw dollars โ€” use them when you benchmark.
  • A positive result means you're ahead after the costs and fees you entered. A negative result means the current numbers don't work โ€” change a lever (raise price, cut a cost, lower ad spend) and recalculate.
  • Treat the output as a planning estimate, not a guarantee. Fees, taxes, and conversion rates shift over time โ€” re-run the numbers whenever a key input changes.

Limitations

  • The calculator handles one shift at a time. For a full week, total each day separately and add the decimal hours.
  • It does not apply overtime rules, premium pay, or shift differentials โ€” those are state, employer, or contract specific.
  • It does not split paid and unpaid breaks for you; only enter the minutes that are actually unpaid.
  • It does not deduct taxes or other payroll deductions; the result is hours worked, not take-home pay.

Common mistakes

  • Entering the break in hours instead of minutes โ€” a half-hour break is 30, not 0.5.
  • Forgetting that paid breaks should not be subtracted; only enter unpaid break time.
  • Typing a clock-out earlier than clock-in for a same-day shift instead of an overnight one.
  • Multiplying the 'h Xm' value (like 8h 30m) by your hourly rate โ€” use the decimal hours figure instead (8.50).

FAQ

Can I add multiple breaks?
Add them up and enter the total break time in minutes.
Does this calculate overtime pay?
No, it only calculates time worked. Multiply the result by your hourly rate to estimate gross pay.
What about paid breaks?
Don't include them โ€” only subtract unpaid break time so paid breaks remain part of your hours.
Will it handle a shift that crosses midnight?
Yes. If the clock-out time is before the clock-in time, the calculator assumes the shift ends on the next day.
How do I total a whole week?
Run the calculator once per day and add the daily totals together. A weekly version is on the roadmap.
What's the difference between decimal hours and hh:mm?
Decimal hours express minutes as a fraction of an hour (8h 30m = 8.50). Most payroll and invoicing systems expect the decimal form.
How do I estimate gross pay from this?
Multiply the decimal hours by your hourly rate. For a yearly view, plug the rate and average hours into the Hourly to Salary calculator.
Does it know about overtime laws in my country or state?
No โ€” those rules vary too widely. Split regular and overtime hours yourself and apply each rate.
Is the break field for the whole day?
Yes โ€” enter the total unpaid break time, in minutes, taken during the shift. Multiple short breaks should be added together.
Can I use this for billing clients as a freelancer?
Yes. The decimal-hours value is what most invoicing tools expect. Track per-client time in separate calculations.
What if I worked through my unpaid break?
If the break wasn't actually taken, set the break field to 0 so all your time counts. If your employer requires you to record breaks regardless, talk to them about pay policy.
