What Are Billable Hours?

Billable hours are the hours you spend directly working on a client’s project or providing a service that the client has agreed to pay for. They are commonly used by freelancers, consultants, agencies, contractors, and other service-based professionals to track the time that can be charged to a client.

For example, if a consultant spends 5 hours working directly on a client’s project, those 5 hours can be considered billable hours.

Not every hour spent working is necessarily billable. Activities such as internal meetings, administrative work, marketing, training, breaks, or vacation time are generally non-billable. However, whether an activity is billable ultimately depends on the agreement or contract with the client. Some businesses may charge clients for certain meetings, travel time, or other project-related activities.

Simple Example

Suppose a freelancer works for 8 hours in a day. If 6 hours are spent working directly on a client project and the remaining 2 hours are spent on administration and other internal tasks, the freelancer may have:

  • 6 billable hours
  • 2 non-billable hours

Tracking billable hours helps professionals understand how much of their working time is actually generating client revenue and can also help with accurate invoicing and project planning.

How to Calculate Billable Hours

If you want to calculate billable hours manually, you can use a simple formula:

    Billable Hours = Total Working Hours − Non-Billable Hours

Example

Suppose you worked 40 hours in a week, but 10 hours were spent on activities that cannot be charged to a client, such as meetings, administration, or internal work.

  • Total Working Hours: 40 hours
  • Non-Billable Hours: 10 hours
  • Billable Hours: 40 − 10 = 30 hours

So, your total billable hours for the week are 30 hours.

How to Calculate Billable Percentage

You can also calculate what percentage of your working time was billable using this formula:

    Billable Percentage = (Billable Hours ÷ Total Working Hours) × 100

Using the example above:

    (30 ÷ 40) × 100 = 75%

This means your billable utilization is 75%, meaning you spent 75% of your total working time on work that could be billed to clients.

A Billable Hours Calculator can perform these calculations automatically, helping you quickly check your billable time and utilization without doing the calculations manually.

Frequently Asked Questions (FAQs)

Billable hours are the hours you spend working on tasks or services that you can charge to a client. For example, time spent designing, developing, writing, consulting, or completing a specific client project may be considered billable.

To calculate billable hours, subtract your non-billable time from your total working hours.

Formula:

    Billable Hours = Total Working Hours − Non-Billable Hours

Example:

If you work 8 hours in a day and spend 2 hours on administrative tasks, meetings, or other non-billable activities:

    8 − 2 = 6 billable hours

This is a simple way of understanding how to calculate billable hours for a workday or project.

There is no universal percentage that applies to everyone. A reasonable billable utilization rate depends on your industry, job role, business model, experience, and responsibilities.

For example, a freelancer who spends most of their time directly serving clients may have a higher billable percentage than someone who also handles sales, administration, marketing, or management.

It depends on the client agreement and the type of meeting. Meetings directly related to a client's project may be billable if your contract allows you to charge for them. Internal company meetings or general administrative meetings are usually non-billable.

Before charging meeting time, check the terms agreed upon with the client.

Yes. Billable hours are particularly useful for freelancers and independent professionals who charge clients by the hour. They can track the time spent on each project and multiply their billable hours by their hourly rate to calculate the service charge.

For example, if you worked 10 billable hours at $40 per hour, your billable amount would be:

    10 × $40 = $400
