Revenue of Deloitte worldwide by industry group 2010-2019

Deloitte generated 12.4 billion U.S. dollars from the financial services industry in 2019, which accounted for around 27 percent of the firm’s overall worldwide revenue of 46.2 billion U.S dollars. Revenue from the consumer industry was the second-largest share, earning Deloitte just less than 11 billion U.S dollars.

Advice you can take to the bank

Demand for industry advice from clients operating in financial services continues to grow, with Deloitte’s revenue from the industry almost doubling from the 6.9 billion U.S. dollars generated back in 2010. Changes within the financial services industry, particularly with regard to technology, could be one reason for Deloitte reporting steady revenue growth in this sector. Mobile banking and cyber security are two changes that are affecting banks today and senior members at these banks are seeking strategic advice from experts to help build for the future. Another noticeable change from 2018 to 2019 was the increase in revenue generated in the energy and resources industry – figures jumped from three billion U.S. dollars to around eight billion U.S. dollars. However, this was caused due to Deloitte moving several large sectors to this industry group from the consumer industry group. Consequently, revenue from the consumer industry dropped by around three billion U.S. dollars.

The consulting service continues to grow

Deloitte provide professional services in many areas, but the largest and fastest growing is consulting. Worldwide revenue from Deloitte’s consulting service reached close to 19 billion U.S. dollars in 2019 – this figure has more than doubled since 2010. The joint revenues of the auditing and consulting services exceeded 34 billion U.S. dollars in 2019 and accounted for around 74 percent of the firm’s overall revenue. The services of auditing and consulting proved to be the most profitable for all the Big Four accounting firms in 2018.
