What Exactly is a Utilization Report?

Before building the report, it’s helpful to understand what it shows and why it's so important, especially for service-based businesses like marketing agencies, consulting firms, and software developers. The utilization rate is a simple but powerful metric that measures how much of an employee’s available time is spent on billable, productive tasks.

The formula is straightforward:

Utilization Rate = (Total Billable Hours / Total Available Hours) x 100

This single percentage tells you a lot about your team’s efficiency, a project’s profitability, and your company’s overall health. Tracking it helps you:

• Improve Resource Planning: See who is over-capacity and at risk of burnout, and who has available time to take on new projects.
• Assess Profitability: A low utilization rate across a project might indicate it's running over budget and isn't profitable.
• Forecast Accurately: Historical utilization data helps you scope future projects more accurately, setting realistic timelines and budgets.

Now, let's get into the practical steps of building this report in Excel with a little help from our AI assistant.

Setting Up Your Raw Data in Excel

Every great report starts with clean, well-structured data. A utilization report typically pulls from a timesheet or project management system. For this report, your raw data should have at least the following columns:

• Employee Name: The person who logged the time.
• Project Name: The project the work was for.
• Date: The day the work was done.
• Hours Logged: The amount of time spent on the task.
• Task Type: A category to distinguish between "Billable" and "Non-Billable" work.

Using ChatGPT to Generate Your Sample Data

If you don't have good sample data on hand or just want to practice, you can ask ChatGPT to create some for you. This is perfect for building a template without using sensitive company information.

Here’s a prompt you can use. Copy and paste it right into ChatGPT:

Act as a data analyst. Generate a sample dataset in CSV format for a small marketing agency's timesheet logs for one month. The dataset should include the following columns: 'Employee Name', 'Project Name', 'Date', 'Hours Logged', and 'Task Type'.

Please include:
- 5 different employees (e.g., Ana, Ben, Carol, David, Eva).
- 4 different client projects and 1 internal project (e.g., 'Client A Website Redesign', 'Client B Ad Campaign', 'Client C SEO', 'Client D Content', 'Internal Admin').
- Dates within the month of May 2024.
- 'Hours Logged' should be a number between 1 and 8.
- 'Task Type' should be either 'Billable' or 'Non-Billable'. Any time logged for the 'Internal Admin' project should be 'Non-Billable'.
- Generate about 50 rows of data.

ChatGPT will generate a perfectly formatted data table. You can simply copy and paste this directly into a new Excel sheet. Name this tab "Raw Time Data" for easy reference.

Building Your Utilization Report Step-by-Step

With our raw data tab ready, let’s create the actual report on a new sheet called "Utilization Report." This is where we’ll summarize the data and perform our calculations. ChatGPT will be our formula-writing guide along the way.

Step 1: Calculate Total Available Hours

First, we need to define the total working hours available for each employee during the period. For a monthly report, a common standard is 8 hours per day, 5 days per week. Let’s assume there are 22 working days in May 2024.

So, the calculation is 8 hours/day * 22 days = 176 hours.

In your "Utilization Report" tab, create a small table with employee names in the first column and their total available hours in the second. For this example, it's 176 for everyone.

Step 2: Summarize Billable Hours with a Pivot Table

Going through the raw data and manually adding up everyone's billable hours would take forever. The most efficient way to summarize this data in Excel is by using a Pivot Table. If you’ve never used one before, don't worry. ChatGPT can walk you through it.

Let's ask ChatGPT for help:

I have raw time tracking data in an Excel sheet called "Raw Time Data". The columns are 'Employee Name', 'Project Name', 'Date', 'Hours Logged', and 'Task Type'.

How do I use a Pivot Table to get the sum of 'Hours Logged' for each employee, but only for tasks where the 'Task Type' is 'Billable'?

While the exact response may vary, ChatGPT will outline these general steps:

1. Select any cell within your "Raw Time Data" table.
2. Go to the Insert tab in Excel and click on PivotTable.
3. Excel will likely auto-select your data range. Choose to place the Pivot Table in a "New Worksheet" or an "Existing Worksheet" (select a cell in your "Utilization Report" tab). Click OK.
4. The PivotTable Fields pane will appear on the right. Now, drag and drop the fields like this:

A new Pivot Table will appear. Above the table, you'll see a filter for "Task Type." Click the dropdown, select "Billable," and click OK. Just like that, you have a clean summary of total billable hours for each team member.

You can now copy and paste these values next to the employee names in the table you started in Step 1.

Step 3: Write the Formula for Utilization Rate

Now that we have Total Available Hours and Total Billable Hours side-by-side, we can calculate the utilization rate. Let's say your data is set up like this:

• Column A: Employee Name
• Column B: Total Available Hours (e.g., 176)
• Column C: Total Billable Hours (from the Pivot Table)

We want to calculate the rate in Column D. Again, let's turn to ChatGPT.

In Excel, cell C2 contains 'Total Billable Hours' and cell B2 contains 'Total Available Hours'. What formula do I use in cell D2 to calculate the utilization rate? Also, how do I format the cell to show it as a percentage?

ChatGPT will prompt you with the correct formula and formatting steps:

Formula:

=C2/B2

Formatting:

1. Enter the formula in cell D2 and press Enter.
2. Right-click on cell D2 and select Format Cells.
3. In the Number tab, choose Percentage and set the number of decimal places to 1 or 2 (common). Click OK.
4. Click on the bottom-right corner of cell D2 and drag it down to apply the formula and formatting to the rest of the employees.

Your table is now complete and shows the utilization rate for every employee!

Step 4: Add Conditional Formatting for Easier Analysis

A good report is easy to understand at a glance. We can use conditional formatting to automatically color-code the rates, making it instantly clear who's hitting their targets.

Here’s our prompt for ChatGPT:

How can I use conditional formatting in Excel on my utilization rate column (D2:D6)? I want to apply the following rules:

- If the percentage is above 85%, color the cell green.
- If it's between 75% and 85%, color it yellow.
- If it's below 75%, color it red.

ChatGPT will give you easy-to-follow directions:

1. Select the cells containing the utilization rates (e.g., D2:D6).
2. Go to the Home tab, click Conditional Formatting, then Highlight Cells Rules > Greater Than....
3. Enter 85% and choose Green Fill with Dark Green Text from the dropdown. Click OK.
4. With the same cells selected, go to Conditional Formatting > Highlight Cells Rules > Between....
5. Enter 75% and 85%, and choose Yellow Fill with Dark Yellow Text. Click OK.
6. Finally, go to Conditional Formatting > Highlight Cells Rules > Less Than....
7. Enter 75% and choose Light Red Fill with Dark Red Text. Click OK.

Your report is now visually intuitive. Green means good, yellow is okay, and red signals that someone might need more billable work or that there's an issue with their projects.

Final Thoughts

By pairing your own knowledge with ChatGPT's knack for generating data and writing formulas, you can significantly streamline creating functional Excel reports. This process takes you from raw timesheet data to a visually appealing, insightful utilization report without the usual headache of figuring out complex Pivot Table configurations or remembering specific formula syntax. The key is to rely on ChatGPT as a procedural guide while you remain in control, always double-checking the logic of the results.

While this is a huge step up from building reports completely by hand, the cycle of exporting data and manually updating spreadsheets still needs to be repeated for every weekly or monthly report. At Graphed , we created a solution that eliminates this cycle entirely. We connect directly to your live data sources, from analytics and marketing platforms to spreadsheets, so your dashboards are always up-to-date. Instead of following steps to build tables, you can just ask a question like, "Show me a chart of employee utilization rates for the last 30 days," and get a real-time visualization instantly, saving you time for the most important part: taking action on your insights.
