In consulting firms, understanding how effectively staff time is utilized is crucial for operational efficiency and profitability. Consultant utilization rates provide insights into how much of an employee's available time is spent on billable work versus non-billable activities. This article delves into the definition of utilization, methods to calculate it accurately, and best practices to optimize these rates, helping firms make informed decisions about resource allocation and performance management.
One of the most important KPIs you can focus on in a consulting firm is staff utilization. I’m often surprised by the number of technical consulting firms I speak with that aren’t measuring their team’s utilization rate. And then, unsurprisingly, they tend not to be in the group of the most profitable ones. Those firms that do measure utilization tend to be the most profitable. In their case what I see more often is some level of uncertainty on whether they are measuring utilization in consulting in the right way for the context of their firm.
At its most basic, utilization is:
number of hours doing work/total number of hours available = UTILIZATION
Simple right? Well, as many of you have probably found in your experience – it isn’t that simple.
How much of the work done was actually billed? And how much should have been billed (Not the same thing!). Should you take paid time off (PTO) or other missed time into the equation? Is all that time accurately logged by everyone on the team anyway?
While challenging, I highly encourage all our clients to find a way to measure utilization in their firm.
As you approach these questions, understand that what is more important is not how you answer them, but that you actually do answer them and set a consistent framework. You may want to consider how other consulting firms in the industry measure their utilization in case you want to benchmark – or you may not. In any case, once our clients have worked through these questions they quickly start to move forward measuring utilization.
Understanding the distinction between billable and non-billable hours is essential for accurately measuring utilization and ensuring profitability. Billable hours include the time spent on client projects that can be invoiced, such as consulting work, reporting, and direct project-related tasks. Non-billable hours, on the other hand, encompass essential but indirect activities like internal meetings, business development, training, and proposal preparation. While non-billable time is necessary for long-term growth, excessive non-billable hours can reduce profitability if not managed properly. A clear categorization of these hours allows consulting firms to better assess their financial health and make informed decisions about staffing, pricing, and operational efficiency.
Consultant utilization rates are a direct reflection of how efficiently a firm is using its workforce. A well-managed utilization rate ensures that billable hours are maximized while still allowing room for necessary non-billable activities like training, business development, and internal projects. Firms that fail to track utilization often struggle with profitability, as unaccounted time can lead to revenue leakage and misallocated resources. On the other hand, overloading consultants with excessive billable work can lead to burnout and decreased quality of service. Striking the right balance is key—understanding and optimizing utilization rates helps firms improve financial performance, allocate resources effectively, and create a sustainable workload for their teams.
Consultant utilization rates have a direct impact on both profitability and resource management. A firm with low utilization may struggle with revenue shortfalls, as too much time is spent on non-billable activities without a clear return. Conversely, firms with extremely high utilization risk overworking their staff, leading to burnout, turnover, and declining work quality. Properly tracking and optimizing utilization allows firms to maintain a steady revenue stream while ensuring employees have enough capacity for professional development, internal initiatives, and business growth. By balancing billable and non-billable time effectively, firms can improve forecasting, allocate resources efficiently, and maintain a sustainable, profitable operation.
Utilization is a critical metric across many industries, but how it’s measured and its implications vary significantly. In consulting, utilization primarily focuses on billable hours—ensuring that staff time contributes directly to revenue. This differs from industries like manufacturing, where utilization might refer to machine uptime, or healthcare, where it could measure patient-facing hours. Unlike fields with tangible outputs, consulting relies on human expertise, making accurate tracking of work hours, project demands, and client expectations essential for profitability. Additionally, consulting firms must balance client work with business development, training, and internal projects—factors that don’t directly generate revenue but are crucial for long-term growth. Understanding these differences helps consulting firms refine their utilization strategies while drawing insights from other industries’ best practices.
If you’re wondering where to start, here’s my advice on moving forward:
An overly simplistic view isn’t a bad place to start – include all the work that is easy to get and you’re confident belongs in the numerator. This can serve as a meaningful benchmark as you get more sophisticated in how you measure. As for the denominator, pick a starting point that you think is consistent with how other firms may measure and is simple – like 2080 hours.
Or, as I often do with our clients, start off with measuring billable utilization simply with the data that is entered into the system:
number of billable hours performed/total number of hours available = billable utilization
This accomplishes two things. First and foremost, it emphasizes using only the information that is in your time tracking system and therefore is easy to get to. Second, the measurement is easily understood by those entering time, making it easier for you to manage.
As you begin to refine your utilization measurement, don’t throw out tracking your previous measurements. More often than not, placing different lenses on the team’s performance will get you deeper insight into your actual productivity and the activities that are truly contributing to the success of the firm – and likely uncover some major inefficiencies.
It’s a marathon, not a sprint – so sticking with measurement over time will get you better insights that can lead to meaningful change. Flip-flopping between different measurements can leave you frustrated and undermine what you’re trying to achieve in measuring utilization.
I love spreadsheets and highly encourage their use. They are a great starting point when you are beginning to plan, track, and manage new KPIs. There is also that sense of pride and ownership that comes with my highly customized spreadsheets but – over time – exporting, cleaning up, cutting and pasting and tweaking will take up a lot of your (and your team’s) time. Often I can’t even get to the data I need to make my calculation meaningful. And the reality is that I can get precious hours back by using flexible tools with direct access to the data I’m trying to analyze. That is why one of our primary goals at EVX is to make measuring utilization (and other consulting KPIs) simple and easy.
To better understand utilization in a consulting firm, let’s walk through a practical example.
A consulting firm wants to calculate utilization for an employee over one month. The employee is full-time and works 40 hours per week.
The employee logs their time as follows:
The firm decides to exclude PTO and holidays from available hours, meaning the new total available hours is:
Using the standard utilization formula:
Utilization=(Billable Hours / Available Hours) × 100
Utilization= (120 / 140) × 100 = 85.7%
An 85.7% utilization rate suggests the consultant spends most of their time on billable work, with a reasonable allowance for internal tasks. If utilization is too low, it may indicate inefficiencies, whereas too high a rate could risk burnout.
By consistently tracking and adjusting utilization, consulting firms can maintain a healthy balance between revenue generation and employee well-being.
Setting appropriate utilization targets is key to balancing profitability and employee well-being. While specific targets can vary depending on the firm’s focus, size, and business model, there are common industry benchmarks and best practices to consider.
In general, most consulting firms aim for utilization rates between 70% to 85%. This range accounts for the need to balance billable client work with necessary non-billable activities such as internal meetings, training, business development, and administrative tasks.
By setting clear utilization targets and following these best practices, consulting firms can effectively manage profitability while fostering a healthy and sustainable work environment for their teams.
Utilization targets in consulting firms vary based on several factors such as firm size, type of consulting (e.g., management, IT, engineering), and employee role. However, there are general industry standards that most consulting firms follow to ensure profitability while maintaining a manageable workload for employees.
For entry-level or junior consultants, utilization targets typically range between 65% and 75%. These employees often spend a significant portion of their time learning, attending training, and supporting senior consultants. Although they contribute to billable work, their role may involve a higher proportion of non-billable hours spent on professional development and internal tasks.
Mid-level consultants, who have gained more experience, generally have higher utilization targets between 75% and 85%. At this stage, consultants are expected to handle more client-facing work, including project execution and client meetings. They may also begin to take on leadership roles for smaller projects or teams, increasing their billable hours.
Senior consultants and managers, who are often responsible for leading larger projects and teams, typically have utilization targets around 80% to 90%. These roles are more client-facing, with fewer non-billable hours dedicated to internal tasks. Their time is largely dedicated to project management, client consultations, and overseeing day-to-day project work.
At the top of the hierarchy, utilization targets for partners and executives are usually 60% to 75%. These leaders spend much of their time on high-level responsibilities such as business development, client relationship management, and strategic decision-making, which are critical for the firm’s growth but are typically non-billable. However, they still contribute to billable hours through key client projects or leadership of large engagements.
For many consulting firms, the average utilization target across all employees tends to fall between 70% and 80%. This ensures the firm is efficiently managing resources, while allowing space for non-billable activities essential to firm operations and growth. For firms with a heavy focus on billable work, such as specialized technical or engineering firms, the average target may skew closer to the 80% mark.
Setting realistic utilization goals is crucial for ensuring a consulting firm remains profitable while maintaining a sustainable workload for employees. Here are the key steps to follow when setting these goals:
Before setting utilization targets, it’s essential to align them with your overall business objectives. Ask yourself:
This understanding will help determine the necessary balance between billable and non-billable hours for each role in your firm.
Utilization goals should be tailored to different roles within the firm. Junior consultants, senior consultants, and leadership should each have different expectations based on their responsibilities:
By assessing the role and responsibilities of each employee, you can set utilization targets that reflect both their ability and workload expectations.
Each firm is unique, so set goals based on the specific context of your business:
Instead of having a single target, consider setting a range of acceptable utilization for each role. For example:
Having a range allows for flexibility while still providing clear expectations for performance.
Non-billable time (e.g., training, internal meetings, business development) is critical to long-term firm health. Be sure to allocate reasonable amounts of time for these activities when setting your targets. Ensure that consultants have enough space in their schedules to maintain a work-life balance and continue developing their skills.
Utilization goals should not be set and forgotten. Regularly monitor performance against the targets, and adjust if necessary:
Once you’ve set realistic utilization goals, ensure that they are clearly communicated to your team. Transparency about how utilization impacts the firm’s success, as well as individual expectations, fosters a culture of accountability and motivation.

Several factors influence utilization in consulting, including the type of projects being worked on, the role and experience level of consultants, and the firm’s business model. Billable hours are affected by project complexity, client demands, and whether the work is time-and-materials or fixed-fee based. Non-billable activities such as training, business development, and internal collaboration also impact overall utilization. Additionally, seasonal fluctuations, employee workload, firm size, and internal resource allocation can all alter the balance between billable and non-billable time.
Project scope, client demands, and team capacity are key factors that directly impact utilization in consulting. The project scope determines the amount of work required and its complexity, which influences the number of billable hours a team can realistically achieve. Client demands play a crucial role, as tight deadlines, frequent scope changes, or high expectations can either push consultants to work longer hours or, in some cases, lead to inefficiencies if expectations aren't clearly defined. Finally, team capacity reflects the firm's ability to allocate the right number of consultants with the necessary expertise to meet project needs without overloading them. Balancing these three elements is crucial for achieving optimal utilization and ensuring both project success and employee well-being.
Time tracking tools play a vital role in managing and optimizing utilization in consulting firms. These tools help capture accurate data on the time spent by consultants on billable and non-billable tasks, offering valuable insights into productivity. By automating time logging, they reduce the risk of errors and ensure that no billable hours are overlooked. Additionally, time tracking tools allow firms to monitor whether consultants are meeting their utilization targets and identify areas for improvement. They also provide the data needed for accurate invoicing, reporting, and financial forecasting, while offering transparency and accountability to both employees and clients. In essence, these tools help firms strike a balance between maintaining profitability and preventing consultant burnout by ensuring realistic workloads.
Improving consultant utilization rates requires clear communication, efficient resource management, and regular tracking. Start by setting clear utilization targets and aligning projects with consultants’ skill sets. Use time tracking tools to capture accurate data, manage resource allocation to avoid overload, and reduce non-billable time. Minimize scope creep by managing project expectations, and invest in employee development to enable consultants to handle more billable tasks. Finally, regularly monitor utilization and adjust as needed to maintain optimal productivity.
Increasing billable hours in a consulting firm requires a focus on efficiency, clear processes, and effective resource management. Here are some strategies to consider:
By implementing these strategies, you can maximize billable hours while ensuring high-quality service and maintaining employee satisfaction.
Balancing utilization with employee well-being is crucial for maintaining productivity and morale. Set realistic utilization targets, avoid overloading staff, and ensure there’s time for rest and professional development. Regularly monitor workload distribution to prevent burnout while maintaining high billable hours, fostering a sustainable work environment for both the firm and its employees.
Common mistakes when measuring utilization and how to avoid them include:
By addressing these mistakes and using a more structured approach to measuring utilization, firms can enhance both profitability and employee satisfaction.
