The collection - which has sold over 24 million copies worldwide since its release in January 2011 - spawned global hits 'Rolling In The Deep' and 'Someone Like You'.
Due to huge success of the album, XL Recordings label boss Richard Russell was able to be paid an £8.5 million dividend, while parent company Beggars Banquet banked a similar sum.
XL Recordings' bank balance rose from £3 million to £32 million in the space of a year, according to figures in The Sunday Times' business supplement (via NME).
Adele's 'Rolling In The Deep' was recently named 'Song of the Year' at the Broadcast Music Inc Awards after accumulating 1.35 million airplays on US TV and radio last year.
Since its release in January 2011, 'Rolling in the Deep' has notched up 2m airplays in total, which is the equivalent of it being heard back-to-back for more than 12 years.
Meanwhile, Adele has recorded the theme song for the latest James Bond instalment Skyfall, which is released in cinemas on October 26.
