Caddies who work for PGA golfers average six figures a year, which is substantially more than the caddies stationed at golf courses across the country. A survey by Salary Expert shows that, on average, caddie masters earn less than $40,000 a year except for those in San Francisco, Manhattan and Los Angeles. Forbes sports writer Matt Woolsey explains that PGA caddies earn an average of $1,000 each week. The better the player performs the bigger cut for the caddie; Tiger Woods' caddie Steve Williams earned over a million dollars in 2006.
