(Total non work time) 30 days. Total days available for work 230 days. Next you have to determine your actual billable time. In most settings, the actual billable time will average 6 hours out of every 8, due to cancellations, no shows, or other problems. So: Available time = 230 days =1840 hrs/yr. Billable time/day = 6/8 =1380 hrs/yr.
The picture at smaller firms is more mixed, with changes in billable hours not always tracking with changes in total hours worked. Overall, average hours worked were 2,044 per year in 2010, compared with 2,025 per year at these same offices in 2009. Overall averages for billable hours per year were 1,799 and 1,772, respectively. The largest firms saw average hours worked increase from 2,134 to 2,208 per year, and billable hours increase from 1,753 per year to 1,859 per year.
