Consulting services industry worldwide - statistics & facts

The consulting services sector has expanded at a fast pace in the last several years, with North America and Europe that have represented the largest regional markets worldwide. The average revenue per management consultant, for instance, reached 212,000 U.S. dollars in 2023. The dramatic growth of the industry between 2020 and 2022 has proven that companies need external consultants with strategic knowledge about business administration, business development, as well as expertise about the industry in which clients operate. This business value was demonstrated by the market size of the industry reaching more than one trillion U.S. dollars in 2022. This expertise in the management consulting industry has often been broken down by service line, and this has normally been represented by financial and strategic categories. Some consulting firms have been used by governments in the outsourcing of public services as trust in the industry has continued.

The North American consulting market

North America, and in particular the United States, is home to the largest consulting services market worldwide. The management consulting market size in the United States was valued at approximately 329 billion U.S. dollars in 2022. It therefore should come as no surprise that the United States is home to some of the most prestigious and successful consulting services companies across the world. The so-called Big Four - Deloitte, Ernst & Young (EY), PricewaterhouseCoopers (PwC), and KPMG - have become household names in recent years. These companies have boasted steadily growing revenue streams and operate in all four corners of the globe where they have employed hundreds of thousands of consultants.

No signs of slowing down

The number of consultants at the leading executive search firms increased significantly over the last few years. In addition to this, the average entry salary for consultants with an MBA or PhD has also increased noticeably in the same time period. An upward trajectory in number of consultants, salaries, market value, and number of management consulting businesses have indicated that this industry may not yet have peaked.
