Now the number one tennis player in the world, British tennis star Andy Murray has won 44 singles titles, as well as a whole bunch of big-money endorsement deals, netting him over $72 million (£58m). We reveal how the ace made his fortune and how he spends the piles of cash.

Back in 2003, Murray experienced his first real taste of success, winning the $10,000 (£7k) ITF Futures Tournament in Glasgow at age 15.

A year later, Murray landed his first long-term sponsorship deal with the Royal Bank of Scotland, which was estimated to be worth $6 million (£4m) in 2006.

Setting himself up for a stellar professional career, Murray won the Junior US Open in September 2004 and garnered BBC Young Sports Personality of the Year a few months later.

The up-and-coming player officially turned professional in 2005, beat then-British number one Tim Henman and ended the year ranked 64th in the world, a rise of 287 places in just five months.

Dwarfing his tennis winnings, Murray signed a four-year sponsorship deal with clothing company Fred Perry in 2005, worth an estimated $6 million (£4m).

Murray didn't do too badly at all during his first year as a tennis pro. By the end of 2005, the Glasgow-born teenager had accrued $151,000 (£103k) in prize money.

By 2006, Murray's then-manager Patricio Apey had scored additional endorsement deals with Tag Heuer and Robinsons drinks, upping the golden boy's total earnings by an estimated $3 million (£2m).

The following year, Murray wowed his ever-increasing fanbase by beating world number one Roger Federer and winning his first ATP title at San Jose in the US, bagging $380,000 (£259k) in the process.

That same year, Murray signed up to be the face of the David Lloyd Leisure chain of sports clubs in the UK, reportedly netting him $1.5 million (£1m).

By the end of 2006, Murray was ranked 17th in the world and had overtaken Tim Henman to become British number one.

His professional career going from strength to strength, Murray rose to world number eight in June 2007, finishing the year ranked a very respectable 11th internationally.

The British tennis star excelled himself in 2008, reaching his first Grand Slam final at the US Open and nailing his first Masters titles.

The same year, Murray's first autobiography, Hitting Back, was published, landing him a six-figure dollar advance from publisher Random House. Murray has released three autobiographies to date.

Murray's prize-winnings skyrocketed in 2008, totaling $3.7 million (£2.5m) by the end of the year.

In 2009, Murray made tennis history by becoming the highest-ranking British player of all time, after hitting the world number three spot in May, and then number two for a time.

With his Fred Perry contract up, Murray signed a five-year sponsorship deal with Adidas in 2009 worth $22 million (£15m), adding considerably to his annual winnings of $4.4 million (£3m).

In 2010 and 2011, Murray won several Masters titles and boosted his earnings by several million dollars.

Doing his nation proud, Murray beat Roger Federer to win gold in the men's singles and silver in the mixed doubles with Laura Robson at the 2012 London Olympics.

Murray achieved his first Grand Slam title in 2012, winning the US Open and a very generous $1.9 million (£1.3m) in prize money.

The following year, Murray mania reached fever pitch when the British tennis star bagged the Wimbledon singles title, beating Novak Djokovic in straight sets.

The first male British Wimbledon champion since Fred Perry in 1936 won $2.3 million (£1.6m) in prize money, which he donated to charity. Later that year, Murray was awarded an OBE.

In 2014, Murray signed a multi-million dollar sponsorship deal with finance company Standard Life, as well as a four-year sponsorship deal with sportswear brand Under Armour worth an estimated $22 million (£15m).

In 2014 and 2015, Murray won his first Davis Cup and clay court titles, and climbed back to the world number two spot after dropping to number 10. During this time, his match winnings hit $11 million (£7.5m).

As if he didn't have enough sponsorship cash to play with, in 2015 Murray signed an endorsement deal with Jaguar worth $2.2 million (£1.5m).

And the money just kept on rolling in. In July 2016, Murray went on to beat Milos Raonic to claim his second Wimbledon title and his third Grand Slam, taking home $2.5 million (£2 million) in the process.

In November 2016, Andy Murray became the first British singles player to become the world number one in the Emirates ATP Rankings. Just a day later, Murray went on to defeat John Isner for his maiden title at the BNP Paribas Masters in Paris. This crown earned the champion a whopping €2.6 million ($2.79/£2.2m).

Earlier this year, the Sunday Times Rich List recorded Andy Murray's net worth as $72 million (£58m), but since winning Wimbledon for the second time and claiming the Paris Masters title, we predict Murray's fortune has risen to some $80 million (£64m). And if he follows in the footsteps of former number one Novak Djokovic he could be set to almost double his fortune over the next few years. So how exactly does he spend it?

Back in 2006, Murray already had millions of dollars in the bank but no desire to spend it. In an interview that year, he claimed to still use the London Underground and said he rarely buys anything worth more than £146 (£100).

In 2008, the usually frugal tennis star shelled out $1.57 million (£1m) on a luxury condo in Miami, which he sold for $2.99 million (£2m) in May 2016, making a very tidy profit.

A year later, Murray moved from his riverside apartment in London to an $8 million (£5.5m) Regency-style mansion in Oxshott, Surrey, England.

While he enjoys few OTT indulgences, Murray, a die-hard gamer, has reportedly installed PlayStation 4 consoles in many of the mansion's rooms.

Murray bought a flashy red Ferrari F430 for $198,000 (£135k) in 2010 but got rid of the “incredibly impractical” sports car after just five months.

The tennis ace replaced the attention-grabbing Ferrari with a “more classy” $180,000 (£120k) Aston Martin Vanquish but has admitted he actually prefers driving his old VW Polo, worth just $15,000 (£10k).

In his first stab at the hospitality business, Murray acquired the £1.8 million ($2.6m) Cromlix House near his home town of Dunblane in 2013, which opened as a five-star boutique hotel the following year.

Murray married his long-time girlfriend Kim Sears at Dunblane Cathedral in April 2015, and cut down on costs by holding the reception at his very own luxury Cromlix House hotel – he did however drop $294,000 (£200k) on the engagement ring.

The British tennis number one and world number two has invested heavily in eight start-ups via UK-based crowdfunding platform Seedrs, including Oppo Ice Cream, Commuter Club, Landbay, We Are Colony, and Readbug.

A global ambassador for the World Wildlife Fund and United for Wildlife, as well as a Unicef UK ambassador, Murray donates a significant chunk of his earnings to charity.
