Cost, Comparison & the Models
What a Family Office Really Costs in 2026
A staffed family office averages ~$3M a year to run, 60–70% of it personnel, ranging from $1M to $10M. What drives the cost — and how a lean model changes it.
Overview
A staffed single-family office costs, on average, around $3 million a year to run — before any investment management fees — with personnel making up 60–70% of that. The figure ranges from roughly $1 million at the low end to $6–10 million for the largest offices. Cost tracks scope and staffing, not just the size of the balance sheet.
Families usually ask what a family office costs and expect a single number. There isn't one. But the benchmarks are consistent enough to plan against, and the biggest variable is a choice, not a given.
What does a family office cost to run?
A staffed family office costs, on average, about $3 million a year in operating expenses. The J.P. Morgan Global Family Office Report places the average near $3.2 million, before external investment management fees. That is the operating cost of the office itself — people, technology, compliance, overhead — not the cost of managing the money.
The average hides a wide range. Creative Planning and others put the practical floor around $1 million a year, rising to $6 million for large offices and $8–10 million for those running $1 billion or more. Two families with similar wealth can sit far apart on this range, and the gap is usually explained by scope and staffing decisions rather than portfolio size.

Why is personnel the biggest cost?
Personnel is the biggest cost because a staffed office is, fundamentally, a team. UBS finds staff costs account for roughly two-thirds of operating expenses, and other benchmarks put personnel at 60–70% of the total. Salaries for a chief investment officer, operations staff, and specialists dominate the budget, and they do not scale down for a smaller family.
This is the structural problem with the staffed model at lower asset levels: the core roles cost roughly the same whether they oversee $150 million or $500 million, so the cost ratio worsens as wealth falls. It is why the same coordination, delivered without full-time salaries, changes the economics so sharply.
Personnel is 60–70% of a family office's running cost — and it doesn't scale down for a smaller family.
What drives the range from $1 million to $10 million?
The range is driven by scope, staffing, and complexity, not assets alone. An office that runs investments in-house, coordinates philanthropy, manages properties, and supports multiple family branches costs multiples of one focused on consolidation and coordination. Campden Wealth identifies staffing and technology as the two main drivers of recent cost inflation, with operating costs up meaningfully since 2020.
Every service a family adds carries a multiplier: more legal work, more tools, more oversight. Scope creep, not investment performance, is what quietly pushes an office from the bottom of the range toward the top.
How does a Lean Family Office change the number?
A Lean Family Office changes the number by removing the payroll that dominates the staffed model. Instead of full-time salaries for expertise a family needs only part of the time, it contracts specialists fractionally and runs on an owned operating system.
A Lean Family Office delivers professional coordination at 5–10% of a staffed office's running cost. (Circle 26 figure — confirm canonical source line.)
Against a ~$3 million staffed baseline, that points to a range broadly consistent with the "very lean" figures external benchmarks cite for smaller offices. The saving is not from doing less coordinating. It is from not paying institutional overhead to do it. The full detail sits in the cost of building versus doing nothing.
How should you think about cost relative to your wealth?
Think about cost as a ratio, not a figure. Benchmarks express family office cost as basis points of assets: commonly 30–120 bps for pure operating costs, with a rough rule of thumb around 0.5–1% (Citi puts all-in costs, including external managers, closer to 1–2%). Below the single-family-office threshold, a staffed office's fixed cost pushes that ratio uncomfortably high.
The useful question is not "what does a family office cost?" but "what cost ratio can our wealth carry for the coordination we need?" For many families, that answer rules out a staffed office and rules in a leaner model — the comparison in lean vs single vs multi.
Frequently asked questions
How much does it cost to run a family office?
A staffed single-family office averages around $3 million a year in operating costs before investment fees, per the J.P. Morgan Global Family Office Report, ranging from roughly $1 million to $10 million depending on scope and staffing. A Lean Family Office delivers comparable coordination at a fraction of that, because it removes the full-time payroll that dominates the traditional model.
What percentage of a family office budget is staff?
Personnel typically accounts for 60–70% of a family office's operating costs, and UBS puts staff at roughly two-thirds of operating expenses — the single largest line item. Because those core salaries do not scale down for a smaller family, staffing is what makes the traditional model expensive at lower asset levels.
Is a family office worth the cost?
A family office is worth it when the cost of the coordination gap it closes exceeds the cost of running it — a comparison that depends on your complexity, not only your wealth. The visible cost of the office has to be weighed against the often-larger, less visible cost of doing nothing. --- **See pricing →**
