How superstar golfer Rory McIlroy made his millions
HE IS estimated to be worth anything up to €55m.And Rory McIlroy's career upswing is set to continue - as he stands to earn another €200m in endorsement deals alone over the next five years.
The 25-year-old has potted more than €24m on the course since turning pro at the age of 17.
But it is his sponsorship deals with major brands such as Nike, Bose and Omega that will continue to prove most lucrative for the Co Down star, according to one PR expert.
Chief executive of PSG Communications Mick O'Keeffe said McIlroy's ongoing success is a certainty provided he maintains his steely focus on the green.
Mr O'Keeffe said: "Rory McIlory's endorsement and sponsorship earnings are now estimated to be in the region of €20m to €25m a year, depending on bonuses, with Nike his biggest earner.
"He is very much a global superstar, and up there with the likes of Ronaldo, Messi, Neymar, LeBron, Tiger, Hamilton, Kobe Bryant, Federer and Nadal.
"He is young and the world number one so his future earnings could be even more."
Mr O'Keeffe noted: "Crucially, his sport is a global sport and massive in the US and Far East, where the big sports marketing budgets sit.
"If his form continues, and it shows no sign of abating, he could earn even more from sponsorship in the coming years and in the region of €40m or more per annum.
"He has huge marketing pulling power in the US."
In hindsight, it appears McIlroy was always destined to hit a hole in one, hitting a 40-yard drive at the age of two.
While his friends were studying for exams, 17-year-old McIlroy netted a cool €15,000 at the 2007 British Masters.
But that was pocket change compared to what he would earn over the next eight years.
In 2013, McIlroy signed a rumoured €190m multi-year deal with Nike, and further deals with audio hardware company Bose and watch manufacturer Omega, all within three months of one another.
