Adele earns £80,000 (NZ$164,300) a day despite not releasing an album in almost four years.
The Skyfall singer - whose last record 21 came out in 2011 - has earned £54 million (NZ$110 million) in the last 22 months up to December 31 2013 through her two companies, according to accounts released yesterday.
The Sun on Sunday newspaper reports Melted Stone made £30 million over 14 months up to April 2013, with a further £8 million coming in over the rest of the year.
Meanwhile, the 26-year-old star paid herself a £5.2 million dividend in the second half of 2013, and she drew a salary of £2.86 million in the latest accounting period, as opposed to £5.6 million for the previous 14 months.

Furthermore, her other company Melted Stone Publishing had sales of £14.4 million over the 22 months, and between them her two firms have £13.1 million profits.
The star is said to be working on her highly-anticipated third studio album - set to be released in 2015 - and she has undergone "photo-healing therapy" to cure her fear of being pictured ahead of her return to the limelight.
A source previously said: "Adele has always been camera shy but with her big comeback imminent her fear of being thrust back into the limelight is growing.
"She knows she will have paps following her every move when her album is released and wants to be better prepared.
"A close friend recommended Adele got in touch with a photographer in the US known as 'the photo healer' for some Skype therapy sessions."
