According to Douglas McCollam, in a 2005 article in The American Lawyer: “Studies show that lawyers need to spend about three hours in the office for every two hours of billable time.”
McCollam goes on to mention a 1958 ABA study, when billable hours were first beginning to take hold in the legal profession, there were approximately 1,300 billable hours per year per lawyer. Compare that with the 2,000 hour requirement at many firms today – where do the extra 50% come from? “Out of their souls” writes McCollam.
A quick back of the envelope calculation shows that a 3,000 hour year is required by an attorney to meet the 2,000 hour requirement – or 60+ hours/week, assuming 2 weeks of vacation.
But can the 3:2 ratio of hours worked to hours billed be improved? Dustin A. Cole, writing for the Illinois State Bar Association, believes so. Dustin writes “attorneys fail to bill from 10 to 25 percent of their legitimate billable hours due to bad recording habits, overwhelm and disorganization, and poor team management.”
He lists Problem #1 as “The Periodic “Reconstruction”: Re-constructing hours at the end of the day may lose you 5 to 10 percent. Waiting a week can lose as much as 15 to 25 percent.”
