Billable hours are more than a time tracking metric. They are one of the clearest indicators of how efficiently a firm converts expertise and working time into revenue.
When firms lack visibility into billable versus non-billable work, profitability gaps often go unnoticed, pricing decisions become guesswork, and capacity planning becomes reactive instead of strategic.
A billable hours calculator helps transform raw time data into meaningful performance insights. By measuring utilization and revenue efficiency together, firms gain a clearer understanding of how teams operate, where time is being spent, and whether current pricing models reflect the true value of services delivered.

Over time, these insights support stronger decision-making across staffing, service offerings, and client engagement strategies. Instead of relying on assumptions, firms can use measurable data to guide growth and improve overall financial performance.

Spreadsheets and disconnected time tracking tools can provide rough visibility into billable hours, but they often create fragmented data across billing systems, financial reporting tools, and internal workflows. This makes it difficult for firms to monitor performance trends, maintain accurate reporting, and confidently plan for growth.

Billable hours are calculated by tracking time spent performing services that can be invoiced to clients. The basic formula is:
Billable Hours = Total Work Time − Non-Billable Time
You can then calculate utilization using:
Utilization Rate = Billable Hours ÷ Total Available Hours × 100
This calculator performs these calculations automatically and also includes profitability metrics.
The value of 1600 billable hours depends on the billing rate. For example:
This number is commonly used as a yearly productivity benchmark for accounting professionals.
7.6 hours equals 7 hours and 36 minutes.
To convert decimal hours into minutes:
Multiply the decimal portion by 60.
Example:
0.6 × 60 = 36 minutes
So 7.6 hours = 7 hours and 36 minutes.
A strong billable utilization rate typically falls between 65% and 80% for accounting firms and advisory teams. The ideal level depends on firm structure, service mix, and seniority level.
Junior staff may have higher utilization targets, while partners and senior advisors usually have lower targets due to leadership, client relationship management, and business development responsibilities.
