Combined revenue of EY worldwide by service line 2009-2024
In 2024, the combined global revenue of accounting firm EY reached over 50 billion U.S. dollars. More than one-third of this came from its assurance services. The firm’s tax and assurance service lines had the biggest year-on-year growth, increasing by 6.3 percent respectively between 2023 and 2024.
Advisory services help to strengthen EY
EY reported growth across three of its four service lines in 2024, which led to the overall global revenue of the firm increasing by around two billion U.S dollars on the previous year. The firm’s assurance services package – providing clients with support in the areas of auditing and financial accounting – remains a key focus and has generated the most income for a number of years. EY’s consulting line, however, continues to attract strong demand from clients and revenue from the service has more than doubled since 2012. One reason for this could be that developments in digital technology are prompting more and more clients to seek advice on topics such as data analytics and cybersecurity, helping them to build their company for the future.
The titans of the accounting world
EY is among the Big Four accounting firms worldwide – third after PricewaterhouseCoopers (PwC) and Deloitte in terms of revenue. EY’s record income contributed to the increase in combined revenue of the Big Four. Proposals and recommendations have been discussed in order to break up the market dominance of the four accounting firms and create competition within the sector, but for the time being the Big Four will continue to audit the financial records of the largest public companies worldwide.
