The turnover of his company Footwork Production has witnessed a slump, going down to USD 17.1 million (2010) from USD 23.2 million (2005).
The footballer who is married to former Spice Girl Victoria Beckham, received a salary of USD 16.2 million in 2009 but due to the decline in profits he received only USD 13.5 million this year, reported Daily Mirror online.
But, despite a drop in worth of USD 37.5 million, Beckham is still valued at USD 150 million, said the newspaper.
The ace footballer is currently going through a rough patch in his personal life too.
A prostitute recently claimed to have had an affair with him and Beckham was also named in a court case over claims of an affair with a married mother-of-two.
