How To Calculate Total Hours Worked? Step-By-Step Manual Process


Here’s a straightforward guide to calculate hours worked step by step.

1. Determine the start and the end time


Document the exact time an employee begins and ends their shift.
For example, if an employee starts at 9:00 AM and finishes at 5:30 PM, record these times accurately. 

This can be done using punch cards, online timesheets, or digital time clocks.

2. Convert the time to military time (24 hours)


Use military time (24-hour format) to simplify calculations. The AM times will remain the same. However, you only need to convert the PM time. You can convert PM times by adding 12 to each hour. 

For example, 3:00 PM becomes 15:00 (i.e., 3+12=15), and 8:45 PM becomes 20:45 (i.e., 8+12=20). 

3. Transform the minutes into decimals


Convert hours and minutes into a decimal format for more straightforward calculations. Divide minutes by 60.
For instance, if an employee’s end time is 17:30, divide 30 by 60 to get 0.5. Thus, the end time in decimal format is 17.5.

Example: 7:45 becomes 7.75 hours, and 17:00 remains 17.00 hours.

4. Subtract the start time from the end time


Now you need to subtract the start time from the end time. 

For instance, if the start time is 7.75 hours and the end time is 17.00 hours, calculate 17.00 – 7.75 = 9.25 hours.

5. Subtract the unpaid time taken for breaks


Deduct any unpaid break time. Convert the break time to decimal format using the same method.
For example, a 30-minute break is 0.5 hours. If the total hours worked were 9.25 and the break was 0.5 hours, subtract 0.5 from 9.25 to get 8.75 hours worked.

How do you calculate hours worked in Excel/Google Sheets (with lunch break)? Manually Calculating Work Hours


To calculate hours worked in Excel or Google Sheets (manually), including lunch breaks, follow these steps below:

Input Data:

  1. Column A: Employee Name
  2. Column B: Start Time
  3. Column C: End Time
  4. Column D: Lunch Break Start Time
  5. Column E: Lunch Break End Time
  6. Column F: Total Hours Worked

Format Cells for Time:

  1. Select the cells in columns B, C, D, and E.
  2. Right-click and choose “Format Cells.”
  3. Select “Time” and choose a suitable time format (e.g., 1:30 PM).

Enter Data:

  • Enter the employee name in Column A.
  • Enter the start time, end time, lunch break start time, and lunch break end time in Columns B, C, D, and E, respectively.

Calculate Total Work Hours:

In Column F, use the following formula to calculate the total work hours minus the lunch break:

=((C2-B2) – (E2-D2))*24

Explanation:

  • (C2 – B2): Calculates the total time from start to end.
  • (E2 – D2): Subtracts the lunch break duration.
  • Multiplying by 24 converts the result from a fraction of a day to hours.

Copy Formula for All Rows:

Drag the formula in Column F down to apply it to all rows with data.

Format Total Hours Worked:

  1. Select the cells in Column F.
  2. Right-click and choose “Format Cells.”
  3. Select “Number” or “Custom” and choose a format that displays hours and minutes (e.g., 0.00).

Example

Additional Tips

  • Ensure that times are consistently entered in the same format.
  • Double-check that the cells are formatted correctly for time calculations.
  • If employees work overnight shifts, additional steps may be required to account for dates.

Following these steps, you can manually calculate hours worked in Excel or Google Sheets, including lunch breaks.

How Do You Calculate The Average Hours Worked Per Week?


If you need to manually calculate employee hours worked per week rather than per day, here’s what you should do:

  • Consistent Hours: For employees with a fixed schedule, multiply the daily hours by the number of workdays. For example, if an employee works 8 hours and 15 minutes daily for 5 days a week: 8.25 hours/day × 5 days/week = 41.25 hours/week
  • Variable Hours: For employees with varying daily hours, calculate the hours worked each day and total them for the week. Ensure that holidays, vacation days, or any time off are included.

Manual calculations can be complex and time-consuming. To simplify this process, consider using specialized online timesheet software like Avaza. These tools automate time tracking and billable & non-billable hour calculations, improving accuracy and efficiency.

Limitations Of Calculating Work Hours Manually


Manual work-hour tracking methods have significant drawbacks that impact accuracy, efficiency, and scalability for every type of business.

1. Human Error


Manual time tracking is prone to mistakes. Individuals might miscalculate, misrecord, or overlook critical data when recording hours by hand. 

Simple errors like mistaking AM for PM or forgetting to log an entry can lead to inaccuracies in reported work hours. These errors can be costly, leading to incorrect payment calculations and potential disputes.

2. Time-Consuming


Tracking hours manually demands significant time and effort. Recording, calculating, and verifying work hours manually involves numerous steps, each susceptible to delays and inaccuracies. 

This process diverts attention from critical tasks like project management and strategic planning. The repetitive nature of manual tracking consumes valuable resources, making it less efficient than automated systems like Avaza.

3. Scalability Issues 


As a business expands, manual time tracking becomes increasingly impractical. Managing time records for a growing workforce involves handling a larger volume of data, which manual methods struggle to accommodate efficiently. 

The complexity and volume of work hours increase, making it challenging to maintain accuracy and consistency.

Manual tracking cannot scale effectively for larger teams or organizations with complex time-tracking needs, leading to potential operational inefficiencies and increased administrative burdens.

What are Considered Work Hours?


Work hours refer to the time an employee spends performing their duties, on-site or remotely. This includes scheduled, paid, or contracted hours but excludes overtime for exempt employees. 

Federal law requires accurate record-keeping for hourly, non-exempt, and exempt salaried employees. Records must detail daily hours worked, clock-in and clock-out times, breaks, overtime, and wages paid. 

Compliance with DCAA (The Defense Contract Audit Agency) timekeeping requirements for government contractors involves tracking hours daily and maintaining records for at least two years. 

Accurate tracking of work hours is essential for ensuring productivity and legal compliance.
