Attestation Update – A&A for CPAs

Technical stuff for CPAs providing attestation services

Concentration of accounting firm revenue

with one comment

Inside Public Accounting released their annual list of revenue for the 100 largest accounting firms. It can be found here.

When I saw the article, I did what any self-respecting CPA would do – – paste the data into a spreadsheet and start crunching the numbers. Here are a few of my observations:

  • Total revenue for Top 100 is $42.7 billion dollars. All percentages I mention will use this as the basis for the calculation.
  • Deloitte, the largest firm, has revenue of $10.9B which is 25.6% of the top 100.
  • The Big 4 have combined revenue of $40.0B, which is 72.6% of the total.
  • To get a firm large enough to surpass #4, which is KPMG, the next 7 firms would have to merge.
  • To get a firm large enough to surpass Deloite at #1, the next 72 firms outside the Big 4 would have to merge.
  • If the 96 firms outside the Big 4 were to merge, they would only be larger than Deloite by 7.1%.
  • 55 firms saw topline revenue increase – 41 firms saw topline revenue decrease.
  • Of the Big 4, Deloitte saw an increase in topline revenue while PwC, Ernst & Young, and KPMG saw topline drop.
