Rory McIlroy's US Masters victory at Augusta last Sunday instantly boosted his bank balance by $4.2m (£3.7m) in prize money.
The win completed golf's prestigious Grand Slam for the Northern Irishman.
But the champion's windfall extends far beyond the tournament purse.
Before his Augusta triumph, McIlroy was already worth £225m according to the Sunday Times Rich List 2024.

This substantial fortune placed him among the world's wealthiest athletes, in the company of sporting icons like Tiger Woods and Cristiano Ronaldo.
His Masters victory has now significantly enhanced both his sporting legacy and financial standing.
Forbes reports McIlroy's total earnings last year reached $83m, with $38m won on the course.
The remaining $45m came from endorsements with top brands.
His impressive roster of sponsors includes Nike, TaylorMade, NBC Sports, Bose and Omega.

Rory McIlroy was pushed all the way by Justin Rose at the Masters on SundayREUTERSWhile exact figures remain private, industry insiders suggest his TaylorMade deal is worth approximately $10m annually.
His Nike contract is believed to be twice that value at around $20m per year.
These lucrative partnerships have formed the foundation of McIlroy's commercial empire beyond tournament winnings.
The completion of golf's Grand Slam has dramatically increased McIlroy's commercial value.
"His contracts with Nike and the others will include bonuses for winning the Masters – you're talking seven figures," Trevor Twamley, chief executive of sports-marketing platform Sport Endorse, said per the Irish Independent.

The victory creates a ripple effect across his endorsement portfolio.
"More Omega watches will be sold, more TaylorMade golf balls, and Rory probably has royalties on all those deals," Twamley adds.
"He is getting a sum per item sold."
This commercial boost could potentially more than double his off-course earnings.
"He earned $45m last year off the course, but it could be up to $100m now with his royalties."

Renewing endorsement deals with McIlroy will now come at a premium, according to Jill Downey, chief sponsorship officer with Core.
"I think there is more to be made, but whether Rory would want to make it is probably the key question," she notes.
Endorsements require time commitments beyond simply wearing branded gear on the course.
"Brands outside of golf, where he is not naturally using their product, would definitely need him to show up in some way," Downey explains.
Rory McIlroy was full of emotion after finally winning The MastersReutersDespite his increased marketability, industry experts believe McIlroy may actually reduce his endorsement portfolio.
With a young family, the golfer is expected to become more selective about commercial partnerships.
McIlroy and wife Erica Stoll had been heading for divorce a year ago.
However, the couple decided to stay together in the end - with the pair, as well as their four-year-old daughter Poppy - all smiles last Sunday.
