What is the Billable vs Non-billable Hours Ratio?

Billable hours are the time spent on client-specific tasks that we will charge directly to the client. These hours are what professionals, especially in the service industry, bill their clients for. However, we spend non-billable hours on tasks that we cannot charge to a client directly. This includes administrative tasks, internal meetings, and other non-client-specific activities.

The ratio between billable and non-billable hours provides insights into the efficiency and profitability of a business or professional. A higher ratio of billable hours shows that we are spending more time on revenue-generating activities.

Importance of the Billable vs Non-billable Hours Ratio

Understanding the ratio between billable and non-billable hours is crucial for several reasons:

Profitability: A higher percentage of billable hours directly translates to increased revenue. By monitoring this ratio, businesses can identify inefficiencies and areas for improvement. Companies can analyze non-billable hours to determine if resources are being wasted on non-essential tasks. If they find that this is the case, they can then reallocate those resources to activities that generate revenue.

Pricing Strategy: If non-billable hours are consistently high, it might indicate that the pricing strategy needs adjustment. Perhaps the business is undercharging for its services.

Why Importance of Billable vs Non-billable Hours Ratio is so important?

How to calculate the Billable vs Non-billable Hours Ratio


Billable vs Non-billable Hours Ratio = Billable Hours / Total Hours (Billable + Non-billable)


Let’s say in a week, an employee logs 30 billable hours and 10 non-billable hours.

Using the formula:


This means that 75% of the employee’s hours were billable.

Difference Between Billable and Non-billable Hours ratio vs Other Metrics

While the billable vs non-billable hours ratio is a critical metric, it’s essential to differentiate it from other related metrics:

  • Utilization Rate: This is the percentage of total hours worked that are billable. It’s a measure of employee efficiency.
  • Recovery Rate: This measures the percentage of billable hours that are actually invoiced to the client. Not all billable hours get invoiced due to various reasons, such as discounts or write-offs.
