How Much Does a Family Office Cost? Fees Explained
For a high-net-worth family, family office cost depends on structure, services, and the complexity of work being coordinated. A dedicated office carries its own staffing and infrastructure costs. A multi-family office shares certain resources across households. An outsourced or hybrid model may price each function separately. Understanding these differences helps families compare proposals more clearly.
Discuss your family’s needs with Activest.
No single standard family office cost exists. Fees may rely on assets under management, a retainer, project work, pass-through expenses, or a combination. Therefore, the most useful comparison examines the services included, third-party costs, cross-border complexity, and who holds accountability for coordinating the family’s financial picture.
This question matters especially for Latin American families with assets, businesses, or family members in more than one country. A headline fee may not show the full cost of reporting, manager oversight, or estate and succession coordination. This guide explains the main fee structures and the questions to ask before comparing proposals. For broader context, see Activest’s family office education guide and its overview of family office services.
How Family Office Cost Reflects Different Fee Structures
Family office fees commonly take one of five forms: an assets-under-management charge, a recurring retainer, project fees, pass-through expenses, or a combination. Each model prices a different kind of work. Start any review with the engagement scope, not the percentage alone. Two similar-looking fees can cover very different responsibilities.
Assets-under-management fees
An assets-under-management (AUM) fee is a percentage of the assets an adviser manages. Depending on the agreement, it may cover investment oversight, financial planning, reporting, relationship management, and coordination. Activest’s February 2026 Form CRS describes a tiered wealth-management fee schedule ranging from 1.00% on assets under $5 million to 0.65% on assets over $20 million. The written agreement controls the applicable percentage, asset scope, services, and billing terms. This schedule is not a universal family-office price or a quote.
Families should ask whether an AUM fee applies to all accounts or only selected assets. They should also clarify how the firm handles assets it does not manage — private investments, cash, and accounts held with other custodians. Fund expenses, custody charges, and other third-party costs may sit outside the adviser fee. Activest’s Form CRS provides the cited fee context; prospective clients should review the current agreement and disclosures before making a decision.
Retainers and project fees
A retainer charges for an agreed package of ongoing work rather than tying every fee dollar to managed assets. This structure may suit a family seeking consolidated reporting, governance support, or coordination across accounts that are not all managed by one firm. The engagement should state what the retainer includes, how often work arrives, and how additional requests are handled.
Project fees apply to a defined assignment — preparing for a business transition, organizing a family governance process, or reviewing a fragmented reporting structure. A clear scope, deliverable, timeline, and approval process help prevent an undefined project from becoming an unexpected expense. Ask whether project work fits within the ongoing relationship or gets billed separately.
Pass-through and third-party costs
Families may still carry responsibility for legal, tax, custody, insurance, accounting, or specialist consulting costs. These expenses are not necessarily adviser compensation. Ask whether the firm pays, marks up, coordinates, or simply passes through each cost. Also ask who approves outside work and how those invoices get reported.
When reviewing wealth management services, request a complete fee schedule and a plain-English explanation of every category. Fees, services, and risks vary by family and agreement. This educational discussion is not individualized investment, tax, or legal advice; consult your CPA, tax professional, and legal counsel about your specific circumstances.
How Family Office Cost Changes by Structure
A single-family office carries the full cost of internal staff, systems, premises, administration, and specialist relationships. A multi-family office may share infrastructure and expertise across households, though that shared model can limit customization or dedicated access. An outsourced model can be more modular. Families should compare accountability, scope, control, and total coordination effort alongside the quoted fee.
| Structure | How costs are commonly allocated | Key question to ask |
|---|---|---|
| Single-family office | The family carries staffing, systems, premises, administration, and specialist costs. | What is the full annual operating budget? |
| Multi-family office | Households share selected infrastructure and professional resources under a defined service model; shared structure may limit customization or dedicated responsiveness. | Which services and resources are included? |
| Outsourced or hybrid | Functions are divided among an adviser and the family’s existing professional network. | Who is accountable for coordination? |
Single-family office economics
A single-family office is an internal cost center. Its expense extends beyond an adviser invoice. Personnel, technology, reporting systems, office operations, compliance, insurance, and outside legal or tax specialists all contribute to the total. Moreover, the family carries the responsibility of hiring, supervising, and retaining the people who perform those functions.
This structure can provide direct control and a highly dedicated team. Staffing can become harder, however, when the family needs specialist knowledge across multiple jurisdictions or disciplines. Any family considering this model should estimate the full operating budget — not just the cost of an investment professional. They should also define who supervises the office and how the family reviews performance, conflicts, and risk.
Multi-family office economics
A multi-family office shares systems and expertise across households. That sharing may make consolidated reporting, investment manager analysis, governance support, and coordination with outside professionals more accessible than hiring each capability directly. The tradeoff is that the family must understand how the provider allocates resources and whether the service model delivers the responsiveness and customization the family expects.
Ask how the provider defines the client relationship. Does one team coordinate the family, or will the household need to manage several separate specialists? Clarify which services are included, which are optional, and whether fees apply to managed assets, a broader asset base, or a separate planning relationship. The answer can change the total value even when the headline percentage looks similar.
Outsourced and hybrid models
An outsourced model can combine an investment adviser with the family’s existing attorneys, CPAs, bankers, insurance professionals, and other specialists. A hybrid arrangement can work well when the family wants a central coordinator without building a complete internal office. However, gaps can appear when no party holds clear responsibility for the whole picture.
Before choosing a hybrid model, create a responsibility map. For each major decision, identify the lead professional, the supporting professionals, and the required information. Also identify who communicates the final recommendation to the family. Coordination delivers value only when it is explicit, documented, and maintained over time.
Do not judge an outsourced provider only by whether its fee is lower than the apparent cost of a dedicated office. Instead, compare the time the family must spend, the quality of reporting, and the availability of specialist coordination. A lower invoice may not represent a lower total cost if the family must recreate the coordination function itself.
What Does Family Office Cost Include?
Depending on the provider, family office fees may include wealth management, financial planning, account consolidation, portfolio reconciliation, investment manager analysis, family business planning, estate and succession coordination, governance support, and vendor oversight. The exact scope varies by agreement. Families should map each desired function to a named responsibility and an identified fee.
- Wealth management and financial planning: Investment oversight, liquidity planning, cash flow analysis, retirement planning, and risk coordination.
- Account consolidation and portfolio reconciliation: Bringing accounts, custodians, entities, and investments into a coherent view.
- Investment manager analysis: Reviewing external managers, mandates, fees, exposures, and alignment with the family’s objectives.
- Family business and strategic planning: Helping a family organize decisions around ownership, liquidity, governance, and continuity.
- Estate, succession, and tax coordination (coordinated with the family’s attorneys and CPAs): Working with the family’s legal and tax team so planning decisions are understood across the professional team.
- Vendor and professional coordination: Organizing outside providers, clarifying responsibilities, and identifying opportunities to reduce avoidable costs.
These services do not all have to come from one firm. Even so, someone should still be responsible for keeping the plan coordinated. A proposal that lists investments without explaining reporting, planning, communication, and specialist coordination may not address the family’s actual need.
Activest describes its family office offering as including wealth management, consolidation and portfolio reconciliation, family business and strategic planning, investment manager analysis, estate and succession coordination, and vendor cost review. Activest does not provide legal or tax advice directly; families should consult their CPA, tax professional, and legal counsel for advice on their specific situation.
For families comparing a broad service relationship, the Activest family office overview and wealth management overview can help identify which functions need discussion. The written proposal remains the source of truth for scope and pricing.
How Cross-Border Complexity Affects the Family Office Cost Equation
Cross-border complexity can raise family office cost because a family’s financial decisions may involve multiple jurisdictions, currencies, entities, custodians, and professional teams. The key question is not whether a provider can eliminate complexity. Rather, it is whether the provider can help the family see the connections, organize the information, and coordinate the right professionals.
A family with roots in Latin America may have U.S. investments, a business abroad, real estate in more than one country, and relatives with different residency or citizenship profiles. Those facts can affect reporting, liquidity planning, estate discussions, and the questions a CPA or attorney needs answered. Fragmented communication — when no person holds a complete view — can add cost quickly.
Families should ask who coordinates with counsel and how the adviser consolidates information from multiple custodians. Additionally, ask how the team documents decisions and which services the adviser performs versus which outside professionals handle instead. Providers can explain their coordination role; for tax and legal outcomes, the family should rely on qualified attorneys and CPAs.
Cultural understanding and communication discipline can matter here. A family may need a team that works comfortably across languages, locations, and generations. Activest’s guide to preserving generational wealth offers related planning context, while its family office work can help connect the financial, reporting, and succession conversations.
How Do You Evaluate Whether a Family Office Is Worth the Cost?
A family office may be worth the cost when the coordination, oversight, and planning it provides clearly exceed the fees and effort required. Base the decision on scope, accountability, transparency, and fit — not on a percentage alone. Compare the expected value with the family’s actual priorities and complexity.
- Define the decisions that need support. List the family, investment, business, estate, reporting, and liquidity questions that currently require attention.
- Map the professional network. Identify the advisers already involved and the gaps between them. Note who receives information, who makes recommendations, and who communicates with the family.
- Request an all-in fee explanation. Separate adviser compensation from custody, fund, legal, tax, insurance, accounting, and other outside costs.
- Test the reporting and coordination process. Ask to see a sample reporting structure or a description of how accounts, entities, managers, and action items are organized. Do not rely on a presentation that does not explain the ongoing process.
- Review conflicts and fiduciary responsibilities. Understand how the firm is paid, what products or services it may recommend, and what duties are described in its disclosures.
- Confirm the service relationship in writing. The agreement should identify scope, billing, termination terms, responsibilities, and the treatment of work outside the standard engagement.
For a family navigating a sale, retirement, succession event, or relocation, the right structure may change over time. Revisit the service model when the family’s assets, businesses, jurisdictions, or decision-making needs change. In our view, a well-structured relationship is designed to make the family’s financial life more understandable, not simply add another invoice.

Frequently Asked Questions About Family Office Cost
What is the average family office cost?
No reliable universal average exists. Family offices differ in structure, services, staffing, asset scope, and complexity. A single-family office carries its own full operating budget. A multi-family office shares resources across households. An outsourced model prices functions separately. Rather than relying on a broad industry figure, compare the complete fee schedule, the services covered, and third-party costs against your family’s actual needs.
Is a multi-family office less expensive than a single-family office?
A multi-family office may share infrastructure and specialist resources, which can make certain capabilities more accessible than hiring them directly. A single-family office, by contrast, carries its own full operating costs. The more useful comparison includes service scope, responsiveness, control, outside expenses, and the family’s time — not the headline fee alone. A shared model may also offer less customization or dedicated access than a fully dedicated office.
Are legal and tax services included in family office fees?
Not always. Families should ask whether legal, tax, accounting, insurance, custody, and specialist costs are included, coordinated, or billed separately. Many providers coordinate with the family’s existing attorneys and CPAs rather than providing those services directly. Activest does not provide legal or tax advice; clients should consult their own qualified professionals for advice on their specific situation.
How are family office fees usually calculated?
Fees may rely on assets under management, a retainer, project work, pass-through expenses, or a combination of these. AUM fees are typically tiered by asset level. Retainers cover an agreed package of ongoing services. Project fees apply to defined assignments. The written agreement should define the assets covered, billing schedule, services included, and any additional costs outside the base fee.
What should I ask before hiring a family office?
Ask who is accountable for coordination across your full financial picture. Ask which services are included versus billed separately. Clarify how outside costs such as custody and legal fees are handled, how conflicts of interest are disclosed, and how reporting works across accounts and jurisdictions. Get the full scope and fee terms in writing, and involve your CPA and legal counsel before finalizing any engagement.
