The report estimates that 88 percent of the money Woods has earned since turning pro in 1996 ($1.16 billion) has come from endorsements.
Woods made $71 million in off-the-course earnings to go with his $12 million on the greens in 2013. His $83 million total take was good enough to top Golf Digest's money list for yet another year.
After earning more than $100 million in endorsements in 2008 and 2009, Woods' off-the-course take underwent a hit due to fallout from news of his extramarital affairs. Things have rebounded slightly from a low of $62 million in endorsement money in 2011, according to the Golf Digest report. But Woods recently lost another deal, as Electronic Arts and Woods announced they were parting ways at the end of 2013 after a 15-year relationship.
Rounding out the top five earners were Phil Mickelson ($52 million), Arnold Palmer ($40 million), Jack Nicklaus ($26 million) and FedEx Cup winner Henrik Stenson, who earned $19 million on the course but only $2.8 million in endorsements.
Rory McIlroy finished in sixth with $18 million in endorsements and $2.6 million on the course. McIlroy signed a huge Nike deal but finished with only one win, the Australian Open, in 2013.
Golf Digest noted that the $40 million earned by the 84-year-old Palmer represented his greatest financial year, 40 years after his last PGA Tour win.
