Mark McGwire’s baseball earnings skyrocketed over his career. As Baseball Reference tells us, he made his MLB debut in 1986, and his first year’s salary was a comparatively meager $60,000. However, things soon started picking up for the big man. In 1988, he raked in a cool $250,000. In 1989, he more than doubled that. In 1990, he tripled that with a salary of $1.5 million. 

That was just the beginning for Big Mac. With the exception of a temporary dip in 1994, his tenure with the Oakland Athletics saw the grand total of his salary and bonuses increase substantially by the year, to the point that he made a cool $7.15 million during his last year with them. When McGwire joined St. Louis Cardinals in 1998, he started making even more than that. In his final season in 2001, McGwire’s reported salary was a nice, even $11 million. 

All in all, McGwire’s (possibly incomplete) total career earnings amounted to a little under $74.4 million, and wealth estimation site Celebrity Net Worth points out that he also made “tens of millions” from assorted endorsements. The site estimates that his current net work is somewhere around $60 million.
