“Was I really undercharging that much? It was an eye opener to actually see how much these hours of – it’s only a quick job – added up.” – Debi H., Digital Marketer

What are billable hours?

Billable hours are the actual hours worked on a task or client project that can be charged to a customer. They are usually billed to the client at an agreed-upon hourly rate and are crucial in calculating the total cost of the service. Billable tasks cover all types of client work, including client phone calls and meetings.

Billable hours examples

Here are a few examples of billable time to make things clear:

  • Legal professionals: In legal services, a billable hour is time spent on tasks such as legal research for a client, drafting legal documents, attending meetings with clients or other lawyers, appearing in court, etc. Explore more in the article: How lawyers track billable hours.
  • Consultant: If you’re a consultant, you may bill your clients for time spent on tasks such as conducting specific research, preparing reports, analyzing data, developing strategies, and providing advice on business operations or management.
  • Freelancer: If you are a copywriter, you may bill clients for time spent on writing articles, editing and proofreading; if you are an SEO freelancer, billable time activities will include keyword research or competitive analysis.
  • Web developer: Web developers who may work for marketing or development agencies may bill their clients for time spent on tasks such as designing and building websites, testing and debugging code, and providing overall technical support.

What are non-billable hours?

Non-billable hours stand for time spent on tasks that cannot be directly billed to a client’s projects, and hence do not increase business revenue. Non-billable work is usually related to business operations and employee development.

Examples of non-billable tasks

Now, let’s see some examples of the most common non-billable work:

  • Team meetings. Meetings that are held internally with your team members to discuss business operations, strategy, or internal processes of the company you work for are typically non-billable activities.
  • Administrative tasks. Tasks such as answering phone calls, replying to emails, filing overall paperwork, and other administrative work count as non-billable work.
  • Professional development. Training, attending conferences, or other professional development activities that can be considered an investment in your professional skills and expertise are non-billable activities.
  • Marketing and business development. Efforts made by a professional or business to promote their services and attract new clients, such as attending networking events or developing marketing materials to generate leads and establish new business relationships, are considered non-billable time.

Hours spent on activities like those we just mentioned are not billed to the client as they’re not directly related to the work you do for them. Can you see the difference between billable vs. non-billable hours now?

Why you should track billable hours

By tracking billable and non-billable hours, you can:

  • Analyze your profitability. By tracking billable hours you can better identify where costs should be reduced and make smarter decisions regarding pricing and resource allocation.
  • Improve client invoicing. Get much more accurate client billing and make sure that each client’s invoice is accurate as customers are paying for the actual hours worked by you or your team.
  • Ensure effective time management. Keeping track of total billable hours helps you to prioritize tasks and work on proper time allocation.
  • Create robust client relationship. Being 100% honest and transparent helps build trust and establish a long and strong working relationship with clients.
  • Track your utilization rate. Billable hours help you keep track of the utilization rate, which is the percentage of an employee’s available working hours that are spent on tasks billable to clients, reflecting their productivity.
  • Keep track of billable hours overrun. Tracking billable hours helps monitor overrun rates by comparing actual time spent on a project to the estimated time, allowing for early detection and management of potential budget overruns.

  • Improve workload management and ensure that employees are not overwhelmed with non-revenue-generating tasks.
  • Improve cost management by getting a clearer picture of the true cost of doing business by accounting for all working hours.
  • Track time spent on employee training and professional development to ensure continuous growth and skill enhancement.
  • Make informed decisions about staffing, project planning, and business development initiatives.

How to calculate billable hours

Calculating billable hours is easy. You need to take how much you’ve worked and multiply it by your hourly rate. 

Billable hours = hourly rate x billable working hours

Check this out:

How to calculate billable hours – example

  • Hourly rate: 40$
  • Billable working hours: 20

Billable hours = 40$ (hourly rate) x 20 (billable working hours)
Billable hours = 800$

Tip: When using Timeular, add your hourly rate to each activity, and it will automatically calculate the total number of billable hours to be added in a client’s invoice.

What’s the most effective billable hours model?

Many professionals are wondering what are the perfect billable hours targets. Each case would be different, and the general rule is that the more, the better.

However, it’s already a great result if your total billable hours make up 60% or more of your work hours. To make it perfect, dedicate 80% of your time to billable activities and 20% to non-billable tasks. Setting and meeting billable hours targets is crucial for maximizing revenue generation, as it helps ensure that employees are focused on productive, revenue-generating activities.

If you are currently spotting more non-billable hours than 20-40% and fail to meet billable hours targets, try to identify each non-billable task, group them, and handle them in a specific time slot, leaving the rest of the week for billable activities.

How to increase billable hours

There are many ways for you to increase your billable hours smartly. Here are a few strategies.

  • Improve time management with a time tracker: Use a billable hours software, such as Timeular, to accurately analyze how you spend your time and find ways to be more productive.
  • Review your work process and optimize your habits: Review your current work habits and try simplifying your workflow to be more efficient and reduce the amount of non-billable hours.
  • Take on additional tasks: It may sound super obvious, but logically, if you can take on more work, it’ll be much easier to reach your billable hour goals. Check with your client if there are additional tasks that can be incorporated into your day. Just make sure you do it rationally and don’t take more than you can handle.
  • Raise your rates: This is another thing that sounds obvious, and it is! Increasing your hourly rates can lead to higher billable hours. Just bear in mind that if your goal is to raise rates, you should do so fairly not to affect your relationship with clients.
  • Automate predictable tasks: There are tasks that we do every day that can easily be automated. Automating repetitive tasks frees up time to work on billable projects.

Just keep this in mind: it’s not all about increasing billable hours. It’s also about providing high-quality service to your clients and building long-term relationships so you can keep working with them in the long run.

With this awareness, you will prioritize billable work instead of non-billable and allocate your time more successfully.
  • Assess project profitabilityBy comparing the amount of time spent on a project to the actual money you get from it, you can assess its profitability and make more appropriate decisions regarding similar projects in the future.
  • Set achievable deadlines: By tracking the time and knowing how much time you spend on similar tasks, you can set more realistic deadlines for future projects and avoid overcommitting and exhaustion.
  • Enhance workflow: When you check the reports you get from tracking time, you quickly identify areas of inefficiency in your workflow, allowing you to make changes to increase productivity. For example, suppose you realize you spend a lot of time on administrative tasks that cannot be billed. In that case, you can delegate or automate them.
  • Bill your clients accurately: The detailed info generated when you track your time can assist you in billing clients correctly and avoiding undercharging.
