Between 2007 and 2009, CT TyMetrix Inc. and The Corporate Executive Board gathered invoice data from over 3,500 law firms and 90,000 individual billers across the nation. Â Ultimately the invoices came to $4.1 billion.
According to the CT TyMetrix Inc. and The Corporate Executive Board  survey on billing rates, Washington, D.C. law firm partners come in at a close second for the highest rates in the United States at $600 an hour for their time.  New York City law firm partners charge the most in the United States at about $700 an hour.  Washington, D.C. associates, however, bill at only $375 an hour, more than in San Fransisco, and just less than Las Angeles.
Over the three years of the CT TyMetrix Inc. and The Corporate Executive Board survey, it was also found that District of Columbia lawyers raised their rates on an average of 10.5%. Â In comparison, lawyers in Detroit only raised their rates 2%, the least in the country, and Dallas invoices showed the highest rate raising at 21.9%.
It seems lawyers nationwide do not necessarily have set rates, however. Â The survey found that 85% of lawyers change their rates for the same work depending on the client.
