Estimated earnings use your entered hourly rate and overtime multiplier. Actual payroll may differ due to taxes, employer policies and applicable labor laws.
Keeping track of your working hours is important for employees, freelancers, contractors and business owners. Our free hours worked calculator helps you calculate the time between clocking in and clocking out, subtract unpaid breaks and track your daily or weekly work schedule. Whether you work a regular 9-to-5 job, rotating shifts or overnight hours, you can use this tool to calculate your total working time without manual calculations.
Enter your starting time, ending time and break duration in the calculator above. It automatically calculates your net working hours, weekly totals, regular hours, estimated overtime and earnings based on your hourly pay rate.
To calculate hours worked, first find the difference between your clock-in and clock-out times. Then subtract any unpaid breaks from the total shift duration.
For example, if you start working at 9:00 AM and finish at 5:30 PM, your total shift duration is 8 hours and 30 minutes. If you take a 30-minute unpaid lunch break, your actual working time is 8 hours.
Here are some common examples showing how to calculate work hours with different schedules and break durations.
| Clock In | Clock Out | Break | Hours Worked |
|---|---|---|---|
| 8:00 AM | 4:00 PM | 30 min | 7.50 |
| 9:00 AM | 5:00 PM | 60 min | 7.00 |
| 9:00 AM | 5:30 PM | 30 min | 8.00 |
| 7:00 AM | 3:30 PM | 30 min | 8.00 |
| 10:00 PM | 6:00 AM | 30 min | 7.50 |
Break deductions can affect your total paid working time. To calculate work hours with breaks, subtract the duration of unpaid breaks from your shift length.
For example:
Important: Not every break is automatically unpaid. Under US federal rules, short rest breaks of around 5 to 20 minutes generally count as paid working time. A bona fide meal period can be unpaid when the employee is completely relieved from work duties. State laws may provide additional protections.
An overnight shift begins on one day and finishes on the following day. Calculating these shifts manually can be confusing because the ending time is earlier on the clock than the starting time.
For example, suppose you clock in at 10:00 PM and clock out at 6:00 AM the next morning. Your total shift duration is 8 hours. After deducting a 30-minute unpaid break, your net working time is 7 hours and 30 minutes.
Our calculator automatically handles overnight shifts when you enter a clock-out time earlier than your clock-in time.
Weekly work hours represent the total time you spend working during a seven-day workweek. To calculate weekly hours, add the net working time from each shift after deducting applicable unpaid breaks.
For example, an employee working five days with 8 hours of net working time each day completes 40 hours in a week.
| Day | Hours Worked |
|---|---|
| Monday | 8.00 |
| Tuesday | 8.00 |
| Wednesday | 8.00 |
| Thursday | 8.00 |
| Friday | 8.00 |
| Saturday | 0.00 |
| Sunday | 0.00 |
| Total Weekly Hours | 40.00 |
Decimal hours are commonly used in payroll systems, employee timesheets and billing records. Instead of writing time in hours and minutes, decimal hours express the total time as a number with a decimal point.
To convert minutes into decimal hours, divide the number of minutes by 60 and add the result to the full hours.
| Hours and Minutes | Decimal Hours |
|---|---|
| 15 minutes | 0.25 |
| 30 minutes | 0.50 |
| 45 minutes | 0.75 |
| 1 hour 15 minutes | 1.25 |
| 1 hour 30 minutes | 1.50 |
| 1 hour 45 minutes | 1.75 |
| 7 hours 30 minutes | 7.50 |
| 8 hours 15 minutes | 8.25 |
Overtime refers to working time beyond the applicable regular working-hour threshold. For many employees covered by the US Fair Labor Standards Act (FLSA), overtime pay is generally required after 40 hours in a workweek at no less than one and one-half times the regular rate of pay, unless an exemption or special rule applies.
For example, if an eligible employee works 45 hours in a workweek, the calculation is:
Use the calculator's weekly hours limit, hourly rate and overtime multiplier to estimate your earnings. Actual overtime eligibility and pay calculations depend on applicable laws, employee classification and payroll rules.
Subtract your clock-in time from your clock-out time. Then deduct unpaid breaks to calculate your net working hours.
Calculate the total time between your starting and ending times, then subtract 30 minutes if your lunch break is unpaid and properly excluded from working time.
Yes. Enter your starting and ending times. The calculator automatically handles shifts that cross midnight.
A 9 AM to 5 PM shift lasts 8 hours. If you take a 1-hour unpaid lunch break, your net working time is 7 hours.
If you work 8 hours per day for five days, your weekly working time is 40 hours, excluding any additional unpaid time not already deducted.
7 hours and 30 minutes equals 7.50 decimal hours. Divide 30 by 60 and add the result to 7.
For most covered non-exempt employees under federal law, overtime is generally due after 40 hours in a workweek at no less than 1.5 times the regular rate of pay. Some exceptions and additional state rules apply.
Yes. Enter your hourly pay rate and working hours. The calculator estimates regular and overtime earnings using your selected settings.
Yes. Use the Add Shift option to enter additional shifts and calculate their combined working hours.
Yes. You can download your weekly work-hour records in CSV format or use the print option to save a PDF copy.
