The difference between middle class and upper middle class is mostly just scale. Bigger house, nicer car, fancier vacations. But the budget categories look pretty much the same.

The ultra-wealthy are a different story entirely.

Their spending doesn’t just have more zeros… it has completely different line items. Things most people never think about, like private security, household staff, and “risk management” as a budget category.

A 2025 study by PropertyShark listed the ten wealthiest ZIP codes in the country. Topping the list was Fisher Island (33109), a private island just off the coast of Miami. I got curious about what a typical spending profile actually looks like for someone living there.

Turns out, there’s nothing “typical” about it.

The median home on Fisher Island costs $9.5 million. Even with a million-dollar down payment, you’re looking at a monthly payment around $65,000 once you factor in property taxes and insurance.

That sounds astronomical. And it is. But here’s the surprising part: housing often makes up just 10% to 20% of the ultra-wealthy’s budget.

For most Americans, housing eats up 30% to 40% of income. The rich spend less proportionally on housing… not because their homes are cheap, but because their income is so high that even a $65,000 monthly payment barely dents it.

It’s a reminder that percentages matter more than dollar amounts when you’re thinking about financial health. Someone spending 15% of their income on a $10 million home is in a better position than someone spending 45% on a $300,000 condo.

Nobody escapes taxes entirely. Not even the ultra-wealthy.

At the highest income levels, taxes can consume around 30% of income. That includes federal and state income taxes, self-employment taxes, corporate taxes, capital gains taxes, dividend taxes, and sales tax on expensive purchases.

Yes, the wealthy have access to tax strategies most people don’t. Depreciation on real estate, opportunity zones, charitable trusts, strategic timing of capital gains. But even with all those tools, they’re still writing enormous checks to the IRS.

The difference is they plan for it. Taxes aren’t a surprise at the end of the year. They’re a line item that gets managed year-round with teams of accountants and advisors.

This is where the ultra-wealthy budget starts looking completely foreign.

“Lifestyle spending” for most people means restaurants, entertainment, maybe a gym membership. For Fisher Island residents, it means private security, dedicated household staff, concierge services, exclusive club memberships, yachts, private jets, and premium wellness services.

These aren’t splurges. They’re infrastructure. The wealthy build systems around their lives to maximize time and minimize friction. A full-time house manager, a personal chef, a driver… these aren’t luxuries in their world. They’re utilities.

Lifestyle spending can account for 20% to 50% of an ultra-wealthy household’s budget. That’s a huge range, and it depends entirely on how they choose to live. Some are flashy. Others are surprisingly understated. But even the “modest” ones are spending more on lifestyle infrastructure than most people earn in a year.

Here’s a budget category that barely exists for most households but becomes significant at the top: risk management.

When you have a lot, you have a lot to lose. The ultra-wealthy spend serious time and money protecting what they’ve built.

It starts with insurance… not just home and auto, but umbrella policies, art and collectibles coverage, kidnapping and ransom insurance (yes, that’s a thing), and specialized liability coverage for household staff.

But it goes beyond insurance. Wealthy families obsess over liquidity and cash flow visibility. They want to know, at any moment, exactly how much liquid cash they have, what’s coming in, and what’s going out over the next six to 24 months. They’re not budgeting to cut costs. They’re budgeting to maintain control and predictability.

Insurance and financial planning typically make up 1% to 5% of a high-net-worth budget. That might sound small, but 1% of a $10 million annual income is still $100,000 spent just on protecting the rest.
