How to calculate billable hours and billable value

To help you understand the calculation of the billable value, let's take Mirabelle as an example:

  • Name: Mirabelle
  • Billable rate: $20 per hour
  • Billable time: 120 hours

The billable value calculation only takes three steps:

  1. Determine your billable rate:

    The first step is to determine the billable rate. The billable rate or hourly rate is the salary you and your employer have agreed upon in exchange for your service for a certain duration, for example, per hour. For Mirabelle, her billable rate is $20 per hour.

  2. Calculate your billable hours or billable time:

    Next, we need to calculate the billable time. The billable time is the amount of time you have worked. Mirabelle has worked for 120 hours. Typically to calculate the billable hours, you need to write down your daily work hours and add all of them together at the end of the period.

  3. Calculate the billable value:

    The last step is to calculate the billable value. You can calculate it using the billable value formula:

    billable value = billable rate × billable time.

    For our billable hours example, Mirabelle's billable value is 20 × 120 = $2,400.

If you need to repeat the above steps many times or want to check the answer, our billable hours calculator is a guaranteed way to find the answer.

Even though we generally use billable hours in part-time and freelancing jobs, some service companies such as law firms and consulting firms also charge their client using billable hours.
