In 2020, the consulting market size in the United States reached a value of 64.4 billion U.S. dollars. After experiencing continuous growth between 2015 and 2019, due to the impact of the coronavirus (COVID-19) pandemic, the consulting sector decreased by 12.5 percent throughout 2020.
What do consultants do?
Professionals working in the consulting sector provide advice in a variety of specialized fields, including management, mergers and acquisitions, expansion in foreign markets, environmental regulations, and real estate, among many others. Organizations hire consultants in order to improve their business performance. In 2020, the global consulting market was estimated at around 132 billion U.S. dollars.
Leading consulting firms
The leading consulting firms are the so-called Big Four - Deloitte, Ernst & Young, KPMG, and PwC. In 2020, the Big Four generated a revenue of approximately 27 billion U.S. dollars combined from consulting services in the United States. While these were the largest companies in terms of revenue, they were not necessarily the top-rated ones. According to consultants, the best employers among consulting firms in 2020 were McKinsey & Company, the Boston Consulting Group, and Bain & Company.
