18 min
Jan 17, 2023

All legal firms seek to provide quality services to their clientele. But inaccurately determining the number of hours you work on projects can hurt your company's bottom line. It's important to understand that your firm or office may still use resources, even when not interacting with clients directly, and that you can bill for it. Therefore, knowing when your organization is using resources is vital. Tools like a free lawyer billable hours calculator will help ensure that your firm is reaching its potential and not missing out on the revenue it deserves.

Calculating your firm's hours should be a priority. Below, we will explore the importance of tracking billable hours, lawyer time tracking tips, and some lawyer time tracker software.

What Are Billable Hours for Lawyers?

A billable hour is an hour you spend putting work into a legal project that you can charge your client for. The hours that are considered ‘billable' are those that generate revenue for the business through work. The monetary rate at which attorney work hours for lawyers are charged is negotiated with the client beforehand.

Some of the most common examples of activities that are billable to clients include:

  • Planning legal strategies
  • Remote meetings
  • Revisions
  • Drafting and filing required documentation
  • Gathering relevant evidence
  • Conducting research
  • Correspondence with clients or other communication related to cases
  • Any miscellaneous work related to a legal project

However, not every hour of work that attorneys do qualifies as billable. This is important since non-billable hours cannot be charged to a specific client. Non-billable hours may include work dedicated to building your client base or promoting your business. 

Some of the most typical tasks that result in non-billable hours for attorneys include:

  • Marketing your office or firm
  • Handling internal communications
  • Professional development hours
  • Meetings with your staff and co-workers
  • Handling issues related to the business structure
  • Administrative tasks
  • Drafting or presenting business strategy proposals
  • Activities to get legal clients 

What Is a Non-Billable Hour?

Not every hour of work that attorneys do qualifies as billable. This is important since non-billable hours cannot be charged to a specific client. Non-billable hours may include work dedicated to building your client base or promoting your business. 

Some of the most typical tasks that result in non-billable hours for attorneys include:

  • Marketing your office or firm
  • Handling internal communications
  • Professional development hours
  • Meetings with your staff and co-workers
  • Handling issues related to the business structure
  • Administrative tasks
  • Drafting or presenting business strategy proposals
  • Activities to get legal clients

Although they are not billable, these activities are critical to the success of a legal practice. Both billable and non-billable hours are a precious resource for any growing business, but it is crucial to track billable hours. Wrongfully charging a client or missing the opportunity to increase your revenue are both drastic missteps for your firm.

What Are the Benefits of Tracking Billable Hours for Attorneys?

Accurately calculating lawyer average billable hours guarantees that your working hours result in the appropriate revenue. Beyond ensuring adequate payment, tracking your hours will give you a clearer picture of your firm's efficiency. 

Using an attorney billable time calculator can reveal the following information about your practice: 

  • Hours and resources you spend on specific projects or cases
  • Profits and losses related to specific tasks
  • Productivity and professional performance measures
  • Data to build more accurate estimates for clients
  • Where and how resources should be expended
  • Effective tactics to ensure efficiency
  • Areas for improvement in quality or consistency 

These are only a few clearest advantages for calculating attorney billable hours. By using an online billable hours calculator, you can help your legal practice thrive.

As you can see, optimizing billable hours can significantly change your law firm profits - watch our podcast with Ryan Kimler to learn more.

How to Calculate Law Firm Billable Hours

Even if you understand the importance of accurately tracking your company's work, you may be unsure how to correctly calculate billable hours for lawyers.

To accurately calculate billing hours for your office or firm, it's essential to follow a strict procedure: 

  • Determine the appropriate hourly rate
  • Record the lawyer working hours related to a project
  • Keep a record of the non-billable hours during that period
  • Total the billable hours after the conclusion of the case
  • Multiply the hourly rate by the number of billable hours
  • Add relevant taxes to this total
  • Account for any associated or applicable fees
  • Draft an invoice for the client 

Tracking your hours will help you determine strategies to increase profitability in future cases and projects. As such, choosing attorney work hours for specific jobs is a crucial part of running an effective legal practice or law firm.

Calculating Attorney Billable Hours With a Chart

A billable hours chart can provide an overview of all the tasks that need to be addressed and how long each should take. This allows attorneys to quickly see how much time they are spending on a given case and ensure they are staying within their client's budget and are not being overcharged for any services.

You can use a billable hours chart to calculate whether attorneys meet billable hours targets at a glance. However, it might be difficult for rookie attorneys or legal clerks to understand that most law firms bill in six-minute increments (or one-tenth of an hour).

The table below shows what a chart for calculating billable hours looks like.

Time Spent (Minutes) Billing Increments (Tenths of an Hour)
1-6 0.1
7-12 0.2
13-18 0.3
19-24 0.4
25-30 0.5
31-36 0.6
37-42 0.7
43-48 0.8
49-54 0.9
55-60 1.0

Examples of How to Use AN Attorney Billable Hours Chart

We will give two instances of using both billable hours, as shown in the table above. 

  1. If you spend 38 minutes preparing legal paperwork, simply trace the column for 'Time Spent (Minutes)' down until you reach the period that contains 37 minutes. So that's the row with 37-42 minutes. Then, follow that row across to obtain 0.7. So you'll bill 0.7 hours for the time you spent writing.
  2. If you spend 2 hours and 30 minutes interviewing your clients to get their side of the story and develop a draft to work with, you'll bill 2.5. That's 2.0 for two hours and 0.5 for 30 minutes (half an hour).

Building Billable Chart Hours in Excel

What is billable hours chart

Excel is another good billable hours law firm tool used to track and manage billable chart hours. You can easily track how long they spend on specific tasks, such as research, interviews, writing legal documents, and appearing in court. With its easy-to-use spreadsheet format, Excel makes it simple to record and analyze data related to the amount of time spent on each task or project. It is suitable for multiple clients or projects.

Additionally, Excel's graphing capabilities enable users to visualize their data in order to identify trends and uncover insights. You may automatically calculate the sum of all your input with the help of built-in functions, eliminating the need for manual computation. 

To get started, 

  • Open up a new Excel workbook and enter the data for your projects, including dates, client or project name, hours, hourly rate, and total and additional data. 
  • Use the built-in features of Excel, such as sorting and filtering, to quickly view the data and make adjustments as needed. 
  • Create billable hours chart and graph to visualize your progress once you have entered all the project data. With these visuals, you can more easily spot any problem areas or opportunities for improvement. 

Attorney Billable Hours Calculators and Software

While identifying billable time is usually straightforward, accurately tracking and invoicing those hours is challenging. Thankfully, many kinds of software can assist you in keeping track of your practice's billable hours.


Asana software

Asana is a software application that enables teams to monitor, manage, and organize their tasks. It integrates with various business-related applications, creating a functional hub for your cases.

How to Increase Attorney Billable Hours: Best Practice

This article section will give you an idea of how to increase lawyer billable hour targets to maximize efficiency. 

Establish a ‘Billable Hour’ Policy

In many law firms, attorneys are expected to bill a certain number of hours daily, weekly, or monthly. However, this can often be difficult to achieve, as there are only so many hours in a day. One way to increase billable hours is to establish a ‘billable hour’ policy.

Under this policy, attorneys would be expected to track their time in increments of 15 minutes (or whatever the firm deems appropriate). They would then bill for those increments, even if they only worked for a few minutes. For example, if an attorney tracked their time and saw that they worked on a particular project for 20 minutes, they would bill for 30 minutes.

This policy would likely result in increased billable hours for attorneys, who would be incentivized to work more efficiently.

One Thing at a Time

Problems arise when attorneys or staff members are hyper-focused on a particular project. This is a normal part of any workflow and is to be expected. 

However, it is important to avoid these employees flooding their supervisors with questions and requests. Too much time spent answering questions can lead to dips in productivity. 

Also, supervisors may be unable to respond promptly. This can lead to project timelines being stretched unreasonably. It is important to avoid this delay to provide clients with high-quality legal representation.

One important strategy for minimizing this type of issue is to allow employees to submit queries and issues early in the workday. Set a specific time for the submission of problems or challenges. 

Upper-level employees can then address each problem on their own. Taking one thing at a time will ensure that your team is working as efficiently as possible.

Stay Focused

Have you noticed that your firm's non-billable hours are too high and your billable hours are too low? If this happens, it is important to investigate how much time you or your employees spend on low-value jobs and tasks. 

In addition to unproductive priorities, distractions and procrastination can cost you dearly. It is critical to remove any potential distractions from the workplace. This is especially true during hours that should be billable. 

Staying focused on the important activities that bring in revenue is critical. Working in teams can also help reduce procrastination since individuals are much more susceptible to distractions.

Keep Track in Real-Time

Do not attempt to determine attorney billable hours only in the aftermath of a project's conclusion. In other words, track your billable and non-billable hours as they happen. 

After time passes, it can become challenging to remember what happened during specific work hours. And whether the task was billable to a client—attempting to rely on memory days or weeks after the fact can result in inaccuracies. 

This may cause incorrect invoices. It may also result in your firm missing out on valuable revenue.

Perform Billable Hours Audit

As any law firm knows, billable hours are the bread and butter of the operation. If attorneys aren't billing hours, the firm isn't making money. That's why it's important to ensure that every billable hour is documented correctly and accounted for.

Go through the documentation for a certain period of time and ensure that all of the hours billed are accurate. This can be time-consuming, but it's well worth it in the end.

If you find that there are discrepancies in the billable hours, you can take steps to correct them. This might involve training attorneys on how to document their time better or changing how the firm tracks billable hours.

Provide Detailed Reports

When billing your clients, it is vital to write full descriptions of your legal services. In the law context, providing detailed billing descriptions is especially important.

Failing to provide clients with a clear description of why they are being charged could result in disputes. Billing and invoice disputes cause your business to waste valuable time and evident frustrations and inconveniences. 

Ensuring that your billing descriptions are complete and thorough will decrease client complaints. For example, suppose you spent an hour on a phone call with a client. Many attorneys would include the description of ‘one-hour phone call’ on the client's invoice. Instead, provide a brief description of the content and importance of the call.

This will ensure unreasonable client disputes occur less frequently, saving you time. Detailed billing reports also ensure you recover money for all calculated billable hours.

Tracking Non-Billable Hours as Well

It is important to keep a record of your firm's billable hours. This is how you ensure that your revenue genuinely reflects your employees' work.

However, it is also crucial to monitor your non-billable hours. Non-billable activities can drastically decrease your billable work hours.

Tracking these tasks will help you to find non-billable activities that can be automated or delegated more productively. As such, monitoring your firm's number of non-billable work hours can ensure you are as profitable as possible.

Increasing the total billable hours each day or week is vital. You should use billable hours for necessary tasks and projects.

Automate Non-Billable Work if Possible

Your firm or practice can increase your revenue drastically by automating some non-billable workflows. Tracking your billable hours and task management are two important elements of automation. 

Automating many non-billable jobs in your law practice allows you to increase your total number of billable hours. It is much more useful to spend an hour on a client's case rather than spend that same time manually completing job duties. 

Using billing hours calculators is a useful way to decrease your non-billable work and increase the accuracy of your invoices and billing. Many digital timers can be integrated into other business-related software. This helps to streamline your workflow.

Tracking Billable Hours

As you can see, tracking your billable hours lawyer data in running a law firm is essential. Providing high-quality legal services to your clients is only possible if the other elements of your firm are handled. 

Wasting time on non-billable work can decrease your income stream. This type of time waste can also cause delays and client disputes. 

Monitoring your employees' time to complete essential job functions will also help you increase efficiency and productivity. A free online billable hour calculator allows you to find areas for improvement in your company's workflow. 

To build your client base and secure future business, consulting with a high-performance law firm digital marketing agency is critical. For more strategies to increase your revenue and decrease waste, contact the specialists at Grow Law Firm.


  • How Many Lawyer Billable Hours Should There Be?

    There is no single or universal answer to the question of how many billable hours a project should require. Each legal case will require different billable hours depending on what is needed.  However, monitoring your billable and non-billable hours over time will allow you to estimate your employee's utilization rates better.  The utilization rate is a measure of productivity determined by dividing billable hours by total available hours and multiplying the result by 100. An online billable hour calculator will help you better understand how many hours a specific case should involve.

  • Should You Outsource Non-Billable Hours?

    It is important to track non-billable time and automate non-billable work when possible. Doing so makes finding ways to enhance your practice's efficiency simpler.  It might seem like non-billable tasks are not a big problem throughout a work week. However, these job functions can significantly reduce the time available to serve your clients' needs. It is often a good idea to hire a person to handle non-billable work. This outsourcing provides you and the other legal specialists time to focus on essential elements of your billable work.
