At 37 years of age, Roger Federer is still playing some of the best tennis of his career, and turning it into tournament trophies.

The former world number one is one of the most successful players of all time. He has won the men's singles tournament at Wimbledon alone eight times since 2003, as well as 20 Grand Slam singles titles all over the world.

Federer is not only one of the most talented athletes on the planet, but also the most profitable. Forbes named him the world's highest-paid tennis player in 2018 , earning $77.2 million (58.3 million) from professional wins and sponsorship deals with companies from Rolex to Credit Suisse.

That figure is only likely to go up, as the Swiss star signed a $300 million sponsorship deal with Japanese clothing brand Uniqlo last July.

From tailored tennis rackets to Swiss mansions, here's how Federer makes and spends his fortune.

Federer has been a force to be reckoned with on the hard courts this year, winning the Dubai Championships, the Miami Open, and reaching the final of Indian Wells. He's risen from seventh in February back up to third in the ATP world rankings.

He's not too interested in his current ranking, though.

"For me, the ranking, at 37 years old, is no longer really the priority," Federer said at a media event earlier this year. Instead, he's focusing on his health and winning the big tournaments, which might mean skipping smaller events here and there.

His success trails back to the age of eight, when he started playing tennis. Born in Basel, Switzerland, on August 8, 1981, his Swiss father, Robert Federer, and South African mother, Lynette Du Rand, encouraged him to play from an early age.

Federer's big break came in 2003, when he won his first Grand Slam title at Wimbledon against runner-up Mark Philippousis. He was just 21 at the time. He received 575,000 ($714,460) for his victory.

One year later, he signed a sponsorship deal with watchmaker Maurice Lacroix. Later, Rolex struck an endorsement deal with Federer worth a reported $15 million. Here he is wearing an impossible-to-find, $14,000 Rolex Sky-Dweller back in 2018. Perks of being an ambassador.

The majority of his $77 million income is thanks to endorsement deals and partnerships, which he is known for across the globe. He's won $3 million in prize money from tennis tournaments in 2019, bringing his career total prize winnings to more than $123 million.

The player is also known for his charity work. He founded the Roger Federer Foundation in 2003, which has since raised $40 million and recently hit its goal of educating one million children in Africa by the end of 2018. He still finds time to visit children who benefit from his charity.

Thanks to his role as a brand ambassador for Mercedes-Benz, Federer also has a large car collection. He partnered with the German auto-maker in 2008, and renewed the deal in 2018. The multiyear partnership is estimated to earn the tennis star $5 million a year.

When he's not on the court, Federer is a keen hiker. Last year, he appeared on "Running Wild with Bear Grylls." "Just slightly upset that he beat me at mini ping-pong on the top of the cliff face," Grylls said.

That's not to say the athlete doesn't like to party in his downtime. He's an ambassador for Moet & Chandon champagne, which recently released a limited-edition bottle to mark his 20th year in professional tennis. The 20 bottles sold for $23,000 a pop but all the proceeds went to the Roger Federer Foundation.

After winning his eighth Wimbledon title in 2017, Federer complained of a "head-ringing" hangover the day after. "[I] got to bed at 5 a.m., then woke up, and just didnt feel good. The last hour or so Im somewhat okay again. I'm happy with that."

When Federer goes out for dinner, variety is clearly the spice of life. "I am a lover of Italian, Japanese, and Indian restaurants," he said recently.

Some of his fortune also went on his wedding to former professional tennis player Mirka Vavrinec in Basel, Switzerland. They had their first kiss at the Sydney Olympics in 2000, and got married in 2009.

His wife is his source of fashion advice. "I used to wear jogging shoes, jeans and a practice shirt, then when Mirka met me, she would look and go, 'Errr, are you sure about this look?'"

Federer's worst fashion mistake came when he won Wimbledon in 2007.

"I went to receive the trophy, and as I walk down I'm a bit nervous, and as I put my hands in my pockets I realise that the pockets are going backwards," he said . "I was like: 'It's too late! I can't change them anymore!' I lifted the trophy, and the pants were on backwards."

If you look closely in this picture you can see that his trousers are on back-to-front.

With his 38th birthday closing in, Federer has taken some time to consider his retirement. He recently told a Swiss newspaper that he has bought "an old bus from the 60s," which he plans to drive around Europe once he has some spare time.
