Answer:
Professional Caddies are salaried at $1,000 per week plus 5% of the tournament purse, 7% of a top 10 and 10% for a victory. This amounts to a heft paycheck.
Tony Navarro : $442, 548 (June 2006 to June 2007)
Allistair Matheson: $337,888
Damon Green started out as a pro, but became a caddy seeking an increase in pay. His 2006/7 season earned him $367,716; more than his 1994/5 season as a pro golfer.
Steve Williams, caddy for Tiger Woods made an incredible $1.27 million last year. He has been Tiger's caddy since 1999, and recently received a $140,000 Ford GT as a tip. Not bad for an afternoon of work.
We must remember, however, that caddies are responsible for their own lodging expenses; and now that golf is international, that can add up quickly. It's estimated that caddies spend 25% of their earnings on lodging expenses. Even so, they are making a lot of money.
Even non pro caddies can make over $1000 per week, as standard tips can be $50 or $100 per round per bag; considering TPC Sawgrass is $350 to play or one can pay over $500 to play Shadow Creek.
