Introduction
This free shift calculator helps you figure out how many hours you work and how much money you earn per shift. Just enter your start time, end time, and break length, and the tool calculates your total. It handles overnight shifts, overtime past 8 hours, and shift types like evening, night, weekend, or holiday pay. You can also add an hourly rate and tax rate to see your gross pay, tax amount, and take-home pay.
Use Simple mode to calculate a single shift, or switch to Advanced mode to log multiple shifts and see your total hours, total earnings, and weekly, monthly, or annual projections. The calculator works for both employees who want to check their pay and employers who need to track labor costs. Every result includes a step-by-step breakdown so you can see exactly how each number was found.
How to Use Our Shift Calculator
Enter your shift times, break length, and pay rate to find out how many hours you worked and how much money you earned. The calculator shows your net hours, gross pay, overtime, tax, and take-home pay.
Calculator Mode: Pick "Simple" to calculate one shift at a time. Pick "Advanced" to log and compare multiple shifts at once.
Point of View: Choose "Employee" to see your take-home pay. Choose "Employer" to see total labor costs instead.
Shift Date: Select the date of your shift. If the date falls on a weekend, the calculator will auto-set the shift type to "Weekend" for you.
Shift Type: Choose the kind of shift you worked. Each type has a pay multiplier. Regular is 1.0×, Evening is 1.25×, Night is 1.5×, Weekend is 1.5×, and Holiday is 2.0×.
Start Time: Enter the time your shift began. Use the 24-hour format or the time picker.
End Time: Enter the time your shift ended. If the end time is earlier than the start time, the calculator treats it as an overnight shift that crosses midnight.
Break Duration (minutes): Enter the total number of unpaid break minutes, such as a lunch break. This time is subtracted from your worked hours.
Hourly Rate: Enter how much you earn per hour in dollars. Leave it blank or set it to 0 if you only want to see hours worked without pay details.
Tax Rate %: Enter your estimated tax rate as a percentage. This is used to calculate the tax amount and your net take-home pay. Leave it at 0 if you do not want tax applied.
Shift Name / Label (Advanced mode only): Give each shift a name like "Morning Shift" or "Weekend Cover." This helps you tell your shifts apart in the table and charts.
What Is a Shift and How Are Work Hours Calculated?
A shift is a set block of time that a person works during the day or night. Most jobs split the workday into shifts so that someone is always on duty. Common examples include a morning shift, an evening shift, and a night shift. Some workers also pick up weekend or holiday shifts when extra help is needed.
How Work Hours Are Figured Out
To find out how many hours you worked, you start with the time you clocked in and the time you clocked out. The total time between those two points is called your gross duration. Next, you subtract any unpaid break time, like a lunch break. What remains is your net worked hours, the actual time you spent doing your job, which our Work Hours Calculator can log for every day of a full week.
For example, if you start at 9:00 AM and end at 5:30 PM, that is 8 hours and 30 minutes, a span you can verify with our Time Duration Calculator. If you took a 30-minute lunch break, your net worked time is 8 hours.
Overtime and Shift Differentials
Overtime is any time worked beyond a standard 8-hour day. In many places, overtime pay is 1.5 times your normal hourly rate. This is often called "time and a half." Employers are usually required by law to pay overtime when workers go past the daily or weekly hour limit.
A shift differential is extra pay added on top of your base rate for working less popular hours. Evening, night, weekend, and holiday shifts often come with a higher pay multiplier. For instance, a holiday shift might pay double (2.0×) your regular rate.
Gross Pay vs. Net Pay
Gross pay is the total amount you earn before anything is taken out. Net pay, also called take-home pay, is what you actually receive after taxes and other deductions are removed. Knowing the difference between the two helps you plan your budget and understand your paycheck.
Why Tracking Your Shifts Matters
Keeping a record of every shift you work helps you make sure you are paid the right amount. It also lets you spot patterns, like how much overtime you tend to work or how much extra you earn from night shifts. Employers benefit too, because accurate shift records help them manage labor costs and stay in line with labor laws.
