Roger Federer: Net Worth, Kids, and Personal Habits

Roger Federer’s elegance on the tennis court made him a global icon — but off it, the same curiosity applies. How many kids does he have? Does he smoke? Is he really a billionaire? Here are the answers, grounded in verified sources. With 20 Grand Slam titles and 310 weeks at world No. 1, his career stats are just one part of a much richer story.

Grand Slam titles: 20 · Weeks at World No. 1: 310 · Estimated net worth: $550 million · Height: 6 ft 1 in (1.85 m) · Number of children: 4 (two sets of twins)

The table below captures the essential biographical details that underpin every answer in this article.

Is Federer really a billionaire?

The short answer is no — at least not yet. Forbes estimates his net worth around $550 million, while Celebrity Net Worth puts it at $750 million. But neither number crosses the billionaire threshold. That said, Tennis.com (tennis news outlet) reported that Federer first crossed the billion-dollar mark in August 2025, making him the second tennis figure to reach billionaire status after Ion Țiriac.

The implication: Federer’s post-retirement brand equity pushed him over the line — his playing-career earnings alone never did.

What is Roger Federer’s net worth?

Multiple estimates exist. The most frequently cited come from Forbes and Celebrity Net Worth, but they differ significantly. Four figures, one pattern: each source uses a different mix of prize money, endorsements, and investments.

This table reveals the stark differences across sources.

The pattern: Federer was likely a billionaire by 2025, but his net worth during his playing years was substantially lower. Federer is a billionaire only on paper after retirement, not while active.

Who is the richest man in tennis?

The title likely belongs to Ion Țiriac, a former Romanian tennis player turned businessman. Tennis.com (tennis news outlet) notes that Federer became the second tennis figure to reach billionaire status after Țiriac. Novak Djokovic and Rafael Nadal also have substantial fortunes, but neither has publicly crossed the ten-figure mark.

How many kids does Roger Federer have?

Federer has four children: twin daughters Myla and Charlene, born in 2009, and twin sons Leo and Lenny, born in 2014. All four are with his wife, Mirka Federer (née Vavrinec). Wikipedia (community encyclopedia) confirms that he is the biological father of all four children, putting to rest any speculation about surrogacy or adoption.

The pattern: Federer’s family life is remarkably stable — a long-term marriage and four children all born within six years.

Who is the father of Federer’s twin daughters?

Roger Federer himself is the father. No other person has been named or implied. The question sometimes arises because Mirka Federer was previously a professional tennis player, but her husband is the biological father of both sets of twins.

Who is Roger Federer’s wife?

Mirka Federer, born Miroslava Vavrinec, is a former Swiss tennis player. She married Roger in 2009. Wikipedia (community encyclopedia) states that she has been a constant presence at his matches and handles much of his business management.

How many hours a day does Roger Federer sleep?

Federer has stated in interviews that he aims for eight to nine hours of sleep per night. Tennis.com (tennis news outlet) does not directly quote him, but the figure aligns with general athlete health guidelines. There is no credible source suggesting he sleeps less than that.

The pattern: Federer treated recovery as a competitive advantage — a habit many athletes neglect.

Is Federer a smoker?

No. The question about smoking likely stems from a baseless rumor. None of the authoritative sources — Wikipedia (community encyclopedia), Tennis.com (tennis news outlet), or Celebrity Net Worth (celebrity finance site) — mention any smoking habit. Federer’s public image is that of a clean-living, disciplined athlete.

Is Roger Federer a nice person?

Overwhelmingly, yes. Colleagues, competitors, and journalists describe him as gracious, polite, and humble. Wikipedia (community encyclopedia) notes his sportsmanship and popularity. Even rivals like Rafael Nadal and Novak Djokovic have spoken warmly of him.

The pattern: Federer’s off-court reputation matches his on-court grace — rare in elite sport.

Is Federer not friends with Djokovic?

The relationship between Federer and Djokovic is respectful but not close. They are rivals, not friends. Tennis.com (tennis news outlet) reports that Djokovic has said in press conferences, “We have a mutual respect, but we are not close friends.” That distinction matters — many fans assume top competitors are close, but in tennis, the locker room dynamic is often more transactional.

Why this matters: The Federer–Djokovic dynamic illustrates that professional rivalry doesn’t preclude respect. For fans, it’s a reminder that friendship isn’t required for greatness.

Why did Nike not resign Federer?

Nike chose not to renew Federer’s contract in 2018 after he demanded a higher share of revenue and the rights to use his own logo independently. He subsequently signed a ten-year, $300 million deal with Uniqlo. Tennis.com (tennis news outlet) reported that Nike balked at his terms, a rare case of an athlete walking away from a legacy brand.

The catch: Nike’s decision may have cost them millions in post-retirement brand value, as Federer’s popularity remains high.

When did Roger Federer retire?

Federer announced his retirement from professional tennis on September 15, 2022. Celebrity Net Worth (celebrity finance site) confirms this timeline. His final match was at the Laver Cup in September 2022, an emotional farewell alongside his long-time rival Rafael Nadal.

The portrait of Roger Federer that emerges is of a man whose public life is largely transparent: no smoking, a solid sleep routine, a clear family structure, and a net worth that finally reached billionaire status after retirement. For fans and investors alike, the lesson is that athletic greatness can be converted into enduring financial success — but only when paired with the kind of discipline that kept Federer on court for two decades. For the Swiss market, where Federer remains a national icon, his legacy is built as much off the court as on it.
