How Much Money Did Rory McIlroy's Caddie Make At The Masters?

For the second time in their careers, Rory McIlroy and Harry Diamond were able to stand side by side on the 18th green at Augusta National Golf Club posing with The Masters trophy on Sunday.

The first occasion was only 12 months ago, but this one is likely to mean just as much given what they have been through together since Diamond came on board in 2017.

Although not requiring a playoff this time around, the Northern Irish pair's triumph in 2026 was far from serene. But at least it didn't involve a playoff as McIlroy won by a single stroke despite a bogey on the 72nd hole.

Having blown a six-stroke lead earlier in the week and facing a two-stroke deficit during the final round itself, there were moments where it seemed as though the best friends would have to wait at least a month for another crack at sealing their latest Major together.

However, McIlroy and his able assistant rallied supremely and fought back to close out the tournament for another incredibly memorable success.

In doing so, the newly-crowned six-time Major winner banked a check for $4.5 million after The Masters raised its prize money payout from $21 million to $22.5 million.

But McIlroy won't keep all of that money, though. Part of it will be lost due to taxes while another key chunk is likely to be forwarded on to his caddie, Diamond as a bonus for all of his hard work across the week.

Every Major champion knows they wouldn't be there without the help of their trusted caddie - the man who not only takes a physical burden off their shoulders but sometimes an emotional one, too.

And with so many incredible perks for winning The Masters on the line this week, needing to share the toll of such a draining week is vitally important.

In terms of how much Diamond is likely to see, it depends on his agreement with McIlroy.

Some players hand out 10% of their prize money to their bagman if they win, with the bonus check reducing depending on how far down the leaderboard they end - providing they make the cut in the first place, of course.

Others will agree a flat percentage no matter where they finish - perhaps something like 8% - it depends on the agreement made by player and their assistant beforehand.

But, based on the above, we can predict McIlroy's looper Diamond is likely to collect a bonus check of between $360,000 and $450,000. Last year, he may well have seen anything from £336,00 to $420,000.

In addition to bonus money, most loopers on show at The Masters will be be paid annually rather than week-to-week, so any extra money they earn at Augusta National is truly a bonus.

And it certainly pays well to be McIlroy's bagman with the World No.2 having picked up over $20 million in tournament prize money alone last year.

Based on information from other caddies, that suggests Diamond tacked on almost $2 million to his annual salary working for McIlroy in 2025. Not bad work if you can get it.
