David Beckham earned nearly STG10 million ($A18 million) from personal sponsorship deals during his first full season with the Los Angeles Galaxy.

Newly released accounts from the official British company registry show that Beckham's income from his Footwork Productions company in the year ending December 31, 2008, soared by 91 per cent from the previous year to 9.97 million pounds.

The company's gross profit of STG12.09 million ($A22 million) only includes income from personal endorsements and is believed to account for two-thirds of Beckham's sponsorship income.

A separate company receives his $US5.5 million ($A6 million) basic salary from the Galaxy, the share of the merchandising he generates for the MLS team and joint endorsements with wife Victoria.
