Serena Williams, one of the highest-paid female athletes of all time, is retiring from tennis after the ongoing 2022 U.S. Open.

Earlier this month, Williams said in a Vogue cover story that she plans to move on from her sport, despite her reluctance, to focus on other endeavors, including growing her family.

At the time she announced her plans to retire, the 23-time Grand Slam champion's net worth was sitting at $260 million, according to Forbes' latest estimate. Here's how she amassed her wealth over the years.

Williams played her first professional tournament in 1995 at the age of 14. She rose to fame in the first few years of the 2000s, finally reaching world No. 1 in singles on the Women's Tennis Association (WTA) rankings in 2002 after winning the French Open and Wimbledon.

Over the course of her career, she has been ranked No. 1 in the world eight times. She won 23 singles Grand Slam titles, 14 doubles titles with her sister Venus Williams as well as gold medals at the Sydney, Beijing and London Olympics.

The 40-year-old Michigan native has so far earned $94 million in career prize money, twice as much as any other female athlete has made, according to Forbes.

In a typical year, she would make $30 million to $40 million from on-court earnings and endorsements, according to Celebrity Net Worth. She reportedly earns $15 million to $20 million per year endorsing companies like Kraft Foods and Nike.

Williams is retiring as the second highest-paid female athlete in the world with $0.9 million on-the-field earnings and $45 million off-the-field earnings in 2021, Forbes reported. She was only surpassed by fellow tennis star Naomi Osaka, who had $2.3 million on-the-field earnings and $55 million off-the-field earnings last year.

Williams will continue to expand her fortune after retirement because aside from her on-court and endorsement earnings, she invested in numerous businesses over the years.

She has investments in more than 60 startups, including fintech companies Propel and Cointracker and consumer product companies Billie and Daily Harvest, through her venture capital firm Serena Ventures, according to Forbes.

In March, Williams' firm raised an inaugural fund of $111 million, with backing from Norwest Venture Partners, Alphabet's Capital G, Kapor Foundation and LionTree, among others.

Williams also sits on the board of SurveyMonkey's parent, Momentive.

In January, she joined NFT company Sorare as an adviser.

Williams also owns a small stake in UFC and football team Miami Dolphins.

Williams married Alexis Ohanian, the co-founder of Reddit, in November 2017. The two share 4-year-old daughter Olympia.

Sisters Venus (L) and Serena Williams will play doubles together at the US Open, their first pairing since 2018 -- they are seen here that year at the French Open in Paris
