How Much Rory McIlroys Caddy Earns Per Tournament Win...

Rory McIlroy's longtime caddy, Harry Diamond, reportedly earns between $1,500 and $3,000 per week plus 5-10% of McIlroy's tournament winnings. The topic is trending today as McIlroy competes in the 2026 RBC Heritage, reigniting interest in golf's behind-the-scenes salaries.

Diamond, a former amateur golfer and McIlroy's childhood friend, took over as caddy in 2017. Their partnership has yielded 18 PGA Tour victories, including four major championships. At the 2026 Players Championship where McIlroy won $4.5 million, Diamond likely earned approximately $450,000 from that single event.

Caddy compensation varies across professional golf. While base weekly rates are standard, the percentage of winnings differs based on player-caddy agreements. Top players like McIlroy typically pay higher percentages than lesser-known professionals.

The RBC Heritage purse this week is $20 million, with $3.6 million going to the winner. If McIlroy claims victory, Diamond would earn around $360,000 before bonuses. These figures explain why golf fans are searching for caddy salary details during major tournaments.

Unlike team sports where salaries are public, golf caddy earnings remain private. The estimates come from anonymous player and caddy interviews over the years. McIlroy and Diamond have never publicly confirmed their financial arrangement.

Caddies also receive performance bonuses for top-10 finishes and sometimes health insurance benefits. The role requires extensive course knowledge, club selection expertise, and psychological support during high-pressure moments.

Golf's popularity surge since 2020 has increased purses and consequently caddy earnings. The topic resurfaces whenever McIlroy or other top players contend, as fans calculate potential payouts in real time during broadcasts.
