How To Calculate Billable Hours
To calculate billable hours, determine how much time you've spent on work that can be charged to a client and multiply that by your hourly billing rate. Many law firms use six-minute billing increments, meaning every 0.1 hour represents six minutes of work.
The basic billable hours formula is: Billable Hours × Hourly Rate = Total Billable Amount
For example, an attorney who bills 25 hours at $250 per hour would generate $6,250 in billable fees.
For tasks that take less than an hour, you'll need to convert minutes into decimal hours using your firm's billing increments. Our calculator takes care of the math so you can focus on the work itself.

Billable Hours Chart: Understanding 6-Minute Increments
Most attorneys track their time in six-minute increments, also called tenths of an hour. This makes it easier to account for shorter tasks, like client calls, legal research, and document review.
Here's a quick billable hours conversion chart using six-minute increments and rounding partial increments up.
For example, a 20-minute client consultation would equal 0.4 billable hours under this method. At an hourly rate of $300, the total would be $120.
Always follow your firm's billing policies, client agreements, and applicable professional conduct rules when rounding time.

What's the Difference Between Billable and Non-Billable Hours?
Billable hours generally include work performed directly for a client or case, such as drafting motions, attending depositions, reviewing discovery, or communicating with clients. Non-billable hours typically include internal meetings, administrative work, marketing, training, and other tasks that keep a law firm running.
Understanding the difference helps attorneys track productivity and determine how much of their workday is spent on revenue-generating activities.

How To Improve Your Law Firm's Billable Hour Efficiency
Logging more hours isn't always the best way to increase profitability. Reducing repetitive work can free up capacity for additional clients, improve turnaround times, and give attorneys more time for the tasks that actually require their expertise.
A few ways to improve billable hour efficiency include:
A few ways to improve billable hour efficiency include:
- Track time as you work: Record time spent on client matters throughout the day rather than trying to reconstruct your activities later.
- Streamline administrative tasks: Use templates, standardized processes, and digital tools to cut down on repetitive work.
- Simplify evidence review: Use searchable transcripts and AI-assisted analysis to locate important statements without repeatedly watching or listening to recordings.
- Monitor utilization rates: Compare billable hours against total hours worked to understand where your team's time is going.
Keep in mind that efficiency doesn't mean billing clients for time you didn't spend. The goal is to make your legal workflows more productive while maintaining accurate, transparent billing.
