The decision to increase his fee from 6-8 crores to 18 crores has apparently been taken following the success of Ajay's recent film Singham.
Ajay Devgn, who made his debut in 1991 with Phool Aur Kaante has withstood the bad weather and has delivered back to back hits in the recent years - Golmaal 3, All The Best, Atithi Tum Kab Jaoge, Rajneeti and Once Upon A Time In Mumbai.
Though most actors have increased their fee over the years, Ajay Devgn charged between Rs 6-8 crore per project, in spite of being one of the most bankable actors in Bollywood.
According to a source, Singham earned a profit of over Rs 100 crore, thereby multiplying Ajay's market value.
However, when a leading English daily contacted Devgn's manager, he refused to comment.
