How Much Does It Cost to Run a Family Office?

Last updated 7 September 2026 · 3 min read

Running a dedicated single-family office typically costs between roughly 875,000 dollars and 6.6 million dollars a year, or about 0.2 to 1 percent of assets, which is why most advisers put the threshold to justify one at around 100 million dollars in wealth, and closer to 250 million for a full-service office.

Key takeaways

  • Typical annual cost to run a single-family office: about 875,000 dollars to 6.6 million dollars (2026 benchmarks from UBS, J.P. Morgan, Campden and Morgan Stanley).
  • People are the cost: personnel is 60 to 70 percent of the budget, and senior investment staff command 300,000 dollars and up.
  • The common threshold is roughly 100 million dollars of wealth, and about 250 million for a full-service office; below that, a multi-family or virtual office is usually better value.

The honest answer starts with a range, because family offices do not disclose and every family is different. But the numbers cluster tightly enough to be useful.

The annual cost

A dedicated single-family office typically costs between about 875,000 dollars and 6.6 million dollars a year to run. The average office spends roughly 3 million dollars, and the largest, managing 1 billion dollars or more, average about 6.6 million dollars, according to the J.P. Morgan Global Family Office Report 2026. Expressed as a share of assets, running costs usually fall between 0.2 and 1 percent per year, though for a small office they can be much higher.

The spread is wide because "family office" describes everything from two people and a laptop to a fifty-person institution with a direct-investing team, in-house counsel and a family-governance function.

Where the money goes

Cost in a family office is, overwhelmingly, people. Personnel accounts for 60 to 70 percent of operating expenses, according to the UBS Global Family Office Report 2026. A family office competes with banks and funds for the same talent, so a senior investment professional commands 300,000 dollars and up, and a chief investment officer far more. The rest goes to technology and reporting, legal and compliance, custody, audit and premises.

The crucial feature is that these are fixed costs. The team, the systems and the overhead exist whether the office is managing 80 million or 800 million. That single fact drives the threshold question.

The threshold that justifies one

Because the cost is largely fixed, the ratio of cost to assets is what matters. Advisers most commonly cite around 100 million dollars in wealth as the level at which a single-family office begins to pencil out, and about 250 million for a full-service office with a complete team and a direct-investing program. Some set the bar higher still, arguing that an office with eight or more staff should not be built below 1 billion dollars.

Below those levels the arithmetic turns hostile. A 1.75 million dollar running cost is roughly 1 percent of a 175 million dollar fortune, which a diversified portfolio can absorb. The same cost on 50 million dollars is 3.5 percent, a drag few returns can survive. This is the well-known "trap" where a family is too wealthy for ordinary wealth management but not yet wealthy enough to run a dedicated office efficiently.

The cheaper models below the threshold

For families below the single-family threshold, two structures deliver most of the benefit at a fraction of the cost. A multi-family office spreads the cost of talent, systems and access across several unrelated families and is often accessible from 10 to 30 million dollars. A virtual family office keeps a small coordinating core and outsources investment, tax, legal and reporting to external specialists, delivering comparable oversight without a full standing team.

The point is not that a family office is unaffordable. It is that the cost is real, largely fixed, and only rational above a certain scale. Match the model to the size of the fortune, and the economics work. Force a full office onto too small a base, and the overhead quietly consumes the very wealth it was built to preserve.

Frequently asked questions

How much does it cost to run a family office per year?
A dedicated single-family office typically costs about 875,000 dollars to 6.6 million dollars a year. The average is around 3 million, and offices managing 1 billion dollars or more average about 6.6 million, according to the J.P. Morgan Global Family Office Report 2026. As a share of assets, that is roughly 0.2 to 1 percent.
How much money do you need to justify a family office?
Advisers most commonly cite around 100 million dollars in wealth as the point where a single-family office starts to make sense, and about 250 million for a full-service office with a complete team and a direct-investing program. Below that, the fixed cost eats too much of the return.
Why is a family office so expensive?
Because its costs are largely fixed and driven by people. Personnel is 60 to 70 percent of the budget, and a family office competes with banks and funds for senior talent. The team, systems and overhead exist whether the office manages 80 million or 800 million, so the cost weighs far more on a smaller asset base.
What is a cheaper alternative to a single-family office?
A multi-family office, which spreads the cost of talent and systems across several families and is often accessible from 10 to 30 million dollars, or a virtual family office, which delivers similar services through outsourced specialists and technology at a fraction of the staffing cost.
