Nadia Comaneci net worth: Nadia Comaneci's net worth is $10 million dollars. Born in Onesti, Romania, Nadia Comaneci began practicing gymnastics at a local gym when she was five. Now legendary coach, Bela Karolyi, had just opened his new gymnastics school and he saw Nadia turning cartwheels on the playground with a friend. He invited both girls to attend the school, and Nadia quickly excelled. At age nine, she became the youngest gymnast to win the Romanian National gymnastics competition ever. She continued to dominate when she moved into senior level competition, including winning Gold in all but one event (she won Silver), at the 1975 European Championships. At the 1976 Olympics in Montreal, she became the first gymnast to be awarded a perfect 10, and the youngest gymnast, at age 14 to ever win All-Around Gold. The scoreboards were not set up to accommodate a score of 10, so her multiple tens were displayed as 1.00. After winning multiple medals over the course of the next five years, and having a combination on the uneven bars named after her, Ms. Comaneci retired from competition.
