The average family office now spends about $3 million a year in operation costs. This figure rises to $6.6 million for offices managing $1 billion or more, according to J.P. Morgan’s 2026 Global Family Office Report.

In the face of these expenses, the importance of selecting the right family office operating model is clear.

As single family office principals consider whether to keep functions in-house or whether to outsource, a number of factors come into play, including:

How much capital does the office manage?
How much is the family willing to spend on running their family office?
How complex are the family’s holdings?
How much control does the family want to maintain?
How involved does the family want to be in the day-to-day operations?

To offer different perspectives on family office models, this article discusses what a family office costs to run, how principals weigh the in-house, outsourced, and hybrid models, the risks that may come with a lean team, and why a growing number of single family office principals choose a hybrid model.

How Much Does It Cost to Run a Single Family Office?

The average annual cost to run a family office is around $3 million, based on figures from the J.P. Morgan Private Bank 2026 Global Family Office Report, which surveyed 333 single family offices across 30 countries.

Beyond that average, annual operating costs can vary widely:

40% of offices spend less than $1 million a year
29% spend between $1 million and $2.99 million
20% spend between $3 million and $6.99 million
11% spend $7 million or more

Costs tend to rise with assets under supervision, though not proportionally.

A common rule of thumb puts the cost of a family office at 0.5% to 1% of assets under management. The J.P. Morgan report suggests treating that shorthand with caution, since it accounts for neither the complexity of the assets being managed nor how much of the talent a family has hired in-house rather than outsourced.

The cost of each operating model is only one dimension for consideration. If you’re also considering a multi-family office model, our comparison article will walk you through all the differences between a single family office and a multi-family model.

How Do Family Office Principals Choose the Right Operating Model?

In-House, Outsourced, and Hybrid: How the Models Compare

When evaluating family office operating models, family leaders weigh a number of factors, including staffing models, cost, control, and continuity. The table below offers a comparison to help you decide which model is right for your family:

Family Office Operating Models Compared

	In-House/ Traditional Single Family Office	Fully Outsourced	Hybrid
Staffing Model	Dedicated employees handle family office functions alongside family leaders	Family leaders outsource functions to a roster of external professionals	A lean internal team handles some functions alongside family leaders, while the rest are outsourced to external specialists
Cost	Higher fixed costs	Variable, but could be less than in-house models, depending on negotiated fees	Fixed cost for core roles, variable for the rest
Control	Maximum; every decision handled by dedicated staff	Shared control; outsourced providers may require strong management to ensure alignment with family goals	Higher on the functions kept in-house, less on the functions delegated elsewhere
Continuity	Vulnerable to key-person departures, especially on a small team	Can survive individual turnover, if the family manages it carefully	Internal roles provide more continuity if providers shif

Which model is the best fit depends on a few factors, including the family’s priorities, as well as the functions family members take on themselves.

This decision varies greatly from family to family.

“Every family office is different because they define the activities they want to manage internally versus externally very differently,” notes TIGER 21 Family Office Chair Chris Cecil in the TIGER 21 Collective Intelligence Report Four Family Office Strategies for Multi-Generation Wealth Preservation.

As Cecil shares in the report, family office principals need to consider this issue carefully and proceed step by step.

“Families need to have a heart-to-heart assessment about what they’re really good at and what activities they actually want to do internally,” he shared. “I suggest they start by focusing only on a few—and building structure and governance around them—before bringing more activities in-house.”

When Does It Make Sense to Set Up a Single Family Office?

Speaking from three decades of experience in wealth management and family offices, TIGER 21 Family Office Chair Tommy Mayes argues that choosing a family office model should be based on scale and complexity, not an arbitrary figure.

In his guest post on how much money it takes to justify a family office, Mayes works through each combination:

Early-stage wealth, low complexity: a traditional advisor or multi-family office
Substantial scale, low complexity: external advisors
Lower scale, high complexity: a hybrid single family office
High scale, high complexity: a full single family office

He also discusses the three reasons families may want to establish a family office. If you’re considering whether a single family office is right, the article offers perspectives for shaping your family’s path forward. Read more.

The Risks When a Lean Family Office Team Handles Too Much

Figures from Deloitte show that the average family office operates with a relatively small team of just 15 employees, managing an average of $2 billion in assets. Larger offices report ~23 staff members, while smaller offices employ ~10.

On leaner teams, the risks include:

Key-person risk. When one person holds a significant amount of institutional knowledge, their departure can create significant gaps.
Thin coverage. Under-resourced teams will tend to do the urgent work immediately and defer work that might still be important.
Weak controls. Segregation of duties—the principle that no one person should control a transaction end to end—is hard to maintain on a very small team. This increases the risk that a mistake will go unnoticed.

Outsourcing can offer support to lean teams and increase overall capacity. The J.P. Morgan Private Bank 2026 Global Family Office Report shares the most common services outsourced by family offices:

52% – Legal services
45% – Trading and market execution
38% – Cybersecurity

In contrast, the functions most often kept in-house include staffing and compensation; financial administration; and balance sheet aggregation.

What Services Should a Family Office Handle Beyond Investments?

Beyond managing the family portfolio, family offices often take on the work that keeps a family’s financial life coordinated: financial administration and bill pay, tax planning and compliance, estate and succession coordination, reporting and balance-sheet aggregation, and, in some cases, the governance and education work that prepares the next generation.

Financial administration, staffing and compensation, and reporting often stay in-house, because they touch the family directly and benefit little from outside expertise. The work that benefits from a specialist’s depth—such as legal services, trading, and cybersecurity—is more often outsourced.

The Rise of the Hybrid Family Office Model

An increasing number of family office principals are choosing a hybrid model. This approach allows a family to maintain control over key functions, while accessing outside expertise, often at a more efficient cost than hiring full-time experts.

In this model:

A lean internal team (sometimes a single trusted executive, plus an administrator) oversees the office activities and manages the outside relationships.
External specialists handle legal, tax, cybersecurity, and some or all of investment management.

Run well, a hybrid model keeps fixed costs low while still giving the family institutional-grade depth in the areas that need it.

In the TIGER 21 Family Office Agenda, Family Office Chair Doug Johnson shares the perspective he’s hearing from Members regarding hybrid models:

“The family office principals I work with are looking at things like, ‘How much does it cost to attract the top talent from a Wall Street firm to my family office and then retain them? How can I compete with those salaries and those retention bonuses? How do I incentivize them?’

And then that calls into question, ‘Do I need that? Why can’t I outsource that?'”

A hybrid approach also reduces the key-person and continuity risks that can come with a very small single family office structure. Even if a member of the internal team leaves, external provider relationships continue.

The hybrid model isn’t always less expensive, and it comes with trade-offs. It requires family leaders to manage a set of distinct relationships rather than a single provider or a single team, and it also requires clarity about who owns which decision.

However, for families who need more than a traditional wealth advisor or multi-family office, yet remain too small for a full-service single family office, a hybrid model can be a smart choice.

“I’m seeing a change toward a modular approach in family offices—a combination of in-house and outsourced,” commented Christopher Rose, TIGER 21 Family Office Chair, in the Family Office Agenda.

“I think you’ll see family offices who previously would not have set up a single family office establish one because they can take the key points and outsource the rest,” he shared.

Whichever model a family chooses, it’s important to keep an eye on governance. For more in that area, explore our article on key governance questions every family office should ask.

What Is the Best Way to Structure a Family Office for Simplicity and Control?

Families looking to balance simplicity and control may look to a hybrid approach, with a lean core team supported by outside specialists. This allows a small internal group to oversee the key functions and decisions, while external providers handle the functions that require particular expertise.

The key factor for making the hybrid model work is clarity around who owns each decision. When these responsibilities are unclear, a hybrid model can become complex and challenging. Defining roles and responsibilities thoughtfully set the stage for a well-functioning hybrid family office.
