​USA TODAY Sports via Reuters ConnectThe Undertaker made a lot of money during his three decades in wrestling, and he has put a number on his best year.Speaking with the School of Hard Knocks, the interview series known for asking wealthy guests how they built their fortunes, Undertaker put numbers on his earnings. He said he became a millionaire early in his career.“I was 27,” The Undertaker said when asked how old he was when he became a millionaire.He was then asked how much he made in his highest-earning year. “Just shy of $15 million,” he said.The Undertaker, whose real name is Mark Calaway, did not say which year that was. He turned 27 in 1992, which was less than two years after he debuted in WWE at Survivor Series in November 1990.His early earnings were a big change from where he started. Before WWE, Undertaker worked in World Class Championship Wrestling and WCW. He said on his Six Feet Under podcast that he was making around $1,200 a week in WCW and was trying to get to $2,000 when he asked for a raise, and that Ole Anderson turned him down. “[Y]ou’re a great athlete, but no one is ever going to pay to see you wrestle,” Anderson told him, according to Calaway.Undertaker went on to become one of the most successful acts in WWE history. He won the WWE Championship four times and the World Heavyweight Championship three times, and he put together a 21-match winning streak at WrestleMania that lasted until his loss to Brock Lesnar at WrestleMania 30 in 2014. He wrestled his final match against AJ Styles in the Boneyard Match at WrestleMania 36 in 2020, said goodbye at Survivor Series that year and was inducted into the WWE Hall of Fame in 2022.Undertaker’s financial advice has also stuck with other stars. Dave Bautista has said the best financial advice he ever got came from The Undertaker: to “always live beneath your means.”The Undertaker has stayed busy since his in-ring career ended. He has hosted the Six Feet Under podcast, worked with talent in WWE and serves as a booker for Lucha Libre AAA.The Reality of What The Undertaker’s Earnings Say About His CareerMark Calaway tells stories from his WWE Hall of Fame Career during UNDERTAKER 1 deadMAN SHOW held at the Wildhorse Saloon Friday, July 29, 2022; Nashville, TN, USA; Mandatory Credit: Alan Poizner-The TennesseanEntertainment Undertaker S 1 Deadman ShowNearly $15 million in a single year puts The Undertaker in rare company among wrestlers.
