## How to Calculate Hours Worked

If you need to track work time using a time card, time sheet, or time clock, then you should follow the steps below. You can calculate the total hours worked in a week by following five simple steps.

### Step One: Convert Times to 24-hour Time

The first step is to convert the starting and ending times to 24-hour time. This allows you to subtract the start time from the end time.

For example, to convert your work hours of 8:00 am to 4:00 pm, 8:00 am stays the same, while 4:00 pm is equivalent to 16:00.

### Step Two: Convert 24-hour Times to Decimal

Next, you need to convert the start and end times to a decimal. So, 8:00 becomes 8.0, and 16:00 becomes 16.0.

That’s a straightforward process for whole hours, but what if you start at 8:15 am? In this case, you would take the number after the colon and divide by 60 to convert it to decimal form.

For example, 8:15 is the same as 8 and 15/60. You can reduce the fraction to ¼, which is converted to 0.25 in decimal form.

### Step Three: Calculate Time for Each Day

The third step is to subtract the start time from the end time. If you work from 8:00 am to 4:30 pm (16:30), you would subtract 8 from 16.5, which equals 8.5 hours.

This is the elapsed time between the start and end times, but does not account for any unpaid breaks during the day. We’ll account for breaks in the next step, if needed.

### Step Four: Subtract Breaks

After you calculate the number of hours you were at work, now you must subtract any unpaid breaks you took during the day.

If you take an hour break for lunch every day, then you would note “10” hours for each day (or enter “1:00” in the “Break Time” column in the Work Hours Calculator). If you took an hour and a half lunch break on a particular day, you would convert that time to a decimal (1.5), or in the calculator, you would enter “1:30”.

### Step Five: Add Daily Hours Together

The final step to calculating work hours for the entire week is to add together the number of hours worked each day throughout the week.

You can also use our hours calculator to calculate the hour for a single day. It also allows the option to enter in multiple breaks.
