Finance, tech, and fashion-and-retail billionaires pay the same prices for jets, yachts, and mansions. The difference is how broad or how concentrated the wealth behind those bills is.
Running costs here mean yearly spending on crew, fuel, maintenance, taxes, insurance, and berthing. Upstox, summarizing the Knight Frank Wealth Report 2025, counts finance and investment as the largest billionaire industry. Tech holds massive total wealth, while fashion and retail holds fewer ultra-large fortunes at the top.

Where does billionaire wealth sit?
Finance and investment leads by headcount with 427 billionaires, including Warren Buffett and Michael Bloomberg. Tech follows with 342 billionaires holding a combined $2.6 trillion, according to Upstox summarizing the Knight Frank Wealth Report 2025 in the billionaire industry breakdown.
Tech wealth is the most concentrated at the top. Upstox, again summarizing Knight Frank, counts nine tech billionaires worth over $50 billion each, versus six in fashion and retail. That concentration matters when one buyer absorbs multi-million-dollar yearly lifestyle bills.
What does private flying cost?
CRAFT reports a median yearly cost of $712,000 for a very light jet flown 200 hours. The same use rises to about $3.49 million for an ultra-long-range jet, before purchase, financing, and depreciation, in the private-jet ownership guide.
CEO Today Magazine frames the ownership jump as $40–$80 million to buy, plus $4–$6 million in yearly operating costs. Its alternative is jet membership without ownership at $500,000–$1.5 million yearly. Membership avoids the purchase but still rivals mansion upkeep every year.
Why do superyachts dominate budgets?
SuperYachtReview pegs annual running costs at 10–15% of vessel value for crew, maintenance, insurance, fuel, and berthing. A $500 million yacht can therefore cost about $50 million yearly, described in the superyacht cost guide.
Crew is a large fixed piece. SuperYachtReview puts crew alone for a 50-meter superyacht at about €600,000–€1 million per year. Charter income can offset up to half of total annual expenses, but the owner still carries the balance.
What does a mega-mansion add each year?
A Los Angeles purchase adds a large one-time tax before upkeep begins. Nicki & Karen Luxury Real Estate reports that a $20 million mansion triggers a $1.1 million Measure ULA transfer tax at 5.5%.
Yearly upkeep is also heavy. Financial Samurai estimates about $500,000 yearly to maintain an $18 million mega-mansion, split as $230,000 property tax, $100,000 staff salary, $110,000 maintenance, and $60,000 utilities.
