The 7 Most Frugal Billionaires in the World

No. 7: Azim Premji (chairman at Wipro Limited (ADR) (NYSE:WIT))

Net worth: $12.2 billion

As founders of one of the biggest technology corporations in the world, Premji is one very wealthy man. Part of the reason why he amassed his fortune is the fact that he is very careful of the money he spends. Premji still drives his personal car, a 1996 Ford, and only takes the rickshaw to travel from the airport in his local Bangladesh. Premji’s frugal ways extend to his facilities, where he monitors the rolls of toilet paper consumed and demands that staff members turn of the lights whenever they leave the office.
