Billable Utilization Rate: What It Is and How to Improve?

Every hour your team spends on non-billable work can quietly eat into your revenue. It can mean more unused work hours, lower profits, and less revenue from the team. That’s why knowing your billable utilization rate matters. It helps you spot where valuable hours are being lost and take action before they affect your bottom line.

To help you improve profitability and maximize your team’s billable time, this guide covers how to calculate billable utilization, benchmark your rate, and identify practical ways to improve it.

What Is Billable Utilization Rate?

Billable utilization rate is the percentage of an employee’s available working hours spent on billable, client work. It helps you understand how effectively your team’s working time is being used to generate revenue. is the percentage of an employee’s available working hours spent on billable, client work. It helps you understand how effectively your team’s working time is being used to generate revenue.

A higher rate means more of your team’s working hours are spent on work that directly generates revenue. For example, a 70% billable utilization rate means an employee spends about 70% of their available working hours on work that directly generates revenue. Regularly measuring it helps you identify unused capacity and make better decisions about workloads and resource planning.

In fact, Sage reports that the average utilization rate is around 70%, with the average changing by only 1% to 2% from one year to the next.

Why Does Billable Utilization Rate Matter?

Your billable utilization rate can directly influence revenue, project profitability, resource planning, and overall business efficiency. Here are some key reasons why the billable utilization rate matters for your business:

How Do You Calculate Billable Utilization Rate?

To calculate the billable utilization rate, divide the total billable hours by the total available working hours, then multiply the result by 100.

Formula:

Billable Utilization Rate = (Billable Hours ÷ Available Working Hours) × 100

Example:

Imagine you have 10 employees. Each employee has 160 available working hours in a month.

Available working hours: 10 × 160 = 1,600 hours

Hours spent on billable work: 1,200 hours

Now, calculate the rate:

Billable Utilization Rate = (1,200 ÷ 1,600) × 100 = 75%

So, your billable utilization rate is 75%. This means your employees spent 75% of their available working hours on billable work, while the remaining 25% was spent on non-billable activities.

Billable Utilization vs. Realization Rate vs. Resource Utilization

These three metrics may sound similar, but they measure different aspects of business performance. Understanding the difference helps you see whether the challenge is with billable time, revenue, or resource capacity.

Causes of Low Billable Utilization

Low billable utilization doesn’t always mean your team is underperforming. It can often point to issues with workload, project planning, or how employees spend their available hours. Common causes include:

How to Improve Billable Utilization Rate

Improving billable utilization starts with understanding where your team’s working hours are going. Follow these steps to identify gaps and increase the time spent on billable work.

Start by calculating your current billable utilization rate. This gives you a baseline and helps you understand how much of your team’s available time is going toward billable work.

1. Measure Your Current Billable Utilization

Start by calculating your current billable utilization rate. This gives you a baseline and helps you understand how much of your team’s available time is going toward billable work.

2. Identify Where Time Is Being Lost

Look at how employees spend their working hours. Identify excessive meetings, administrative tasks, waiting time, project delays, and other activities that reduce billable hours.

3. Review Your Project Pipeline

Check whether you have enough upcoming billable work for your available workforce. A weak project pipeline can leave employees with unused capacity.

4. Match Employees with the Right Projects

Assign employees based on their skills, experience, and availability. The right project-to-employee match can reduce delays and help employees spend more time on productive billable work.

5. Balance Workloads Across the Team

Identify employees with too much work and those with unused capacity. Redistribute tasks where possible to keep workloads balanced.

6. Reduce Unnecessary Non-Billable Work

Cut down on unnecessary meetings, repetitive administrative tasks, and other activities that take valuable time away from billable projects.

7. Monitor Utilization Regularly

Review billable utilization regularly instead of checking it only at the end of a project. Regular reviews help you spot declining utilization early and make timely adjustments.

8. Improve Based on the Data

Use the insights from your utilization data to adjust project assignments, workloads, staffing, and processes. Continue measuring the rate to see whether your changes are actually improving utilization.

Frequently Asked Questions

Quick answers to the questions people ask most

What is a good billable utilization rate?

A good billable utilization rate depends on your industry, employee roles, project type, and the amount of non-billable work your team handles. Instead of aiming for the highest possible rate, set a target that supports healthy workloads while keeping enough time for essential non-billable activities.

Does billable utilization include PTO and holidays in available hours?

Usually, PTO, holidays, and other approved time off should not count as available working hours. Excluding them gives you a more accurate billable utilization rate because you measure billable hours against the time employees were actually available to work.

What is the difference between billable utilization and billable rate?

Billable utilization measures time, while billable rate measures money. Billable utilization shows the percentage of available working hours spent on billable work, while the billable rate usually refers to the amount you charge a client for an hour of work.

How often should you measure billable utilization?

You should measure billable utilization regularly, such as weekly or monthly, depending on your business and project cycles. Regular reviews help you spot declining utilization, unused capacity, or workload issues early and make adjustments before they affect project profitability.

What tools track billable utilization rate automatically?

Time tracking and workforce analytics software can automate billable utilization tracking by recording working hours, organizing project time, and separating billable from non-billable hours. Tools such as Time Champ can give you utilization insights through automatic time tracking, timesheets, project tracking, reports, and analytics.
