RIA vs. Family Office: Which Is Best for Your Family?

Ken Hargreaves, CFP®, AIF®, AWMA®, CRPC® · October 16, 2026

Does significant wealth mean you need a dedicated family office? Compare an independent RIA, a single-family office and the multi-family office middle ground. A hypothetical example of two families with $100 million shows how service costs affect what they keep—and why complexity matters more than wealth alone.

If your family has significant wealth, you have several options for managing it. You can handle it yourself, although the work can be difficult to fit around a business, career, and family. You can establish a dedicated family office to oversee everything from investments and real estate to estate planning. Or you can work with a wealth management firm, such as an independent, fee-only registered investment adviser (RIA), that offers personal attention and a strategy built around your circumstances. 

To show how that choice affects what a family spends and ultimately keeps, in this paper we'll compare two hypothetical families that take different approaches to managing their wealth. Each has $100 million invested after selling a family business. One lives in Venice and the other in Sarasota, and both want their wealth to provide retirement income and a lasting inheritance for their children.

The Venice family hires an independent registered investment adviser, or RIA. The Sarasota family establishes a dedicated family office, hiring professionals to oversee its investments and broader financial affairs.

Significant wealth might make a family office sound like the natural next step. Yet a family can have substantial assets and a fairly manageable financial life. If an RIA can provide the analysis and ongoing advice the family needs, the extra expense of a dedicated office can consume money without solving an additional problem. Who comes out on top? Let's first examine what each arrangement involves.

How the Relationship Is Structured

ModelPayment StructureWhat to Understand
Fee-Only RIAClient-paid asset-based, fixed, or hourly feesPlanning depth and the total cost of advice and outside specialists
Multi-Family OfficeShared-service fees; compensation varies by providerWhich additional services the family needs and what they cost
Single-Family OfficeFamily-funded staff, systems, and outside professionalsTotal operating cost and responsibility for running the organization

These categories overlap. A multi-family office may be an RIA. Service scope and costs vary by provider. Sources: 1–5.

The Independent RIA

A registered investment adviser, or RIA, is registered with the SEC or state securities authorities. Investment advisers owe fiduciary duties to their advisory clients, including an obligation to act in their best interests. However, RIA simply describes a regulatory status; it doesn't automatically establish independence, fee-only compensation, or a particular level of expertise.1

A planning-focused independent RIA can bring substantial depth to a family's finances. Its work may include investment management, retirement-income analysis, tax-aware withdrawal planning, and modeling the personal financial consequences of a business exit. The firm can work with the family's CPA and attorney while conducting its own detailed financial analysis.

Independent RIA: Pros and Cons

Pros

  • Investment and retirement planning can be tailored to the family.
  • Existing holdings can be reviewed before making portfolio changes.
  • The firm can work with the family’s CPA and attorney.
  • The family can obtain planning support without employing its own office staff.

Cons

  • Planning depth and customization vary by firm.
  • Outside tax and legal specialists may add to the total bill.
  • Asset-based fees can create incentives to retain assets under management.
  • Extensive household or entity administration may exceed the engagement’s scope.

Potential benefits depend on the firm and engagement. RIA registration alone doesn’t establish fee-only compensation or planning expertise. Sources: 1–2.

Customization is especially visible when a client arrives with investments accumulated over many years. Appreciated shares, concentrated holdings, and different account types require judgment. Moving everything into a standard portfolio could trigger taxes or overlook money needed soon. A thoughtful transition begins with the existing holdings and explains what to keep, what to change, and the consequences of each decision.

Be aware that a fee-only RIA still has incentives to manage. An asset-based fee, for example, can favor retaining money under management over using it to repay debt. The firm's disclosures and explanations should make those conflicts understandable.2 The attraction is a structure that reduces product-sales incentives and supports individualized advice, with accountability for the conflicts that remain.

The Single-Family Office

A single-family office is an organization dedicated to one family's affairs. Depending on its scope, it may employ investment professionals, accounting staff, and an executive who oversees the operation. Outside attorneys and other specialists can supplement the team. More extensive offices may also oversee properties, household staff, or philanthropic administration.3

Single-Family Office: Pros and Cons

Pros

  • The family directly shapes its team, priorities, and responsibilities.
  • Dedicated staff can support recurring work across businesses and entities.
  • Investment oversight can sit alongside property and philanthropic administration.
  • A continuing team can build familiarity with complex family affairs.

Cons

  • The family funds salaries, systems, and outside professionals.
  • Hiring, oversight, and staff continuity create ongoing responsibilities.
  • Technology, reporting, and cybersecurity require continuing investment.
  • Operating costs may exceed the value of the support a less complex family needs.

Scope and costs depend on the family’s needs and the office’s design. A dedicated team doesn’t guarantee better investment or planning outcomes. Sources: 3, 5.

That degree of control comes with the work of being an employer and managing an operating budget. Importantly, salaries are only part of the expense. Technology, reporting, cybersecurity, professional services, and staff continuity all need their own funding and oversight.3

A family whose finances require extensive daily oversight may have enough work to support that organization. But a large investment portfolio, a retirement-income plan, and periodic estate or tax decisions don't automatically require employees dedicated to one household. A capable RIA and outside specialists may already cover those needs.

What the Two Families Keep

For our Venice and Sarasota families, the comparison starts with $100 million in each investment portfolio. This is investable wealth, rather than a net-worth figure that includes a home or an unsold business. Both families need investment oversight, retirement-income planning, and outside tax and legal advice, but neither has extensive daily business or household administration.

What should a dedicated office cost at that level? The answer depends on the team and the work it takes on. Staffing, systems, outside professionals, and the services kept in-house all affect the bill. A useful comparison starts with a budget for the support your family actually needs.3, 5

For our example, suppose the Venice family pays an annual RIA fee of 0.30% on the $100 million portfolio, or $300,000, and another $50,000 for outside tax and legal work. Its combined cost is $350,000. The Sarasota family sets a $750,000 budget for a small dedicated office: $500,000 for staff compensation and benefits, $100,000 for systems and administration, and $150,000 for outside professionals. These are assumed budgets for the example, not market averages or WealthGen fee quotes.

With an assumed 6% return before those costs, each portfolio produces a $6 million gain. After paying the assumed annual bills, the Venice family retains $5.65 million and the Sarasota family retains $5.25 million. The additional office expense absorbs $400,000 that the Venice family keeps invested. 

Same Investment Gain, $400,000 Less Retained

Venice: RIA and Outside Specialists

Starting portfolio$100,000,000
Gross gain at 6%$6,000,000
Annual service costs−$350,000

$5,650,000

5.65% of the starting portfolio retained as a gain, before taxes and other investment expenses.

Sarasota: Dedicated Family Office

Starting portfolio$100,000,000

5.25% of the starting portfolio retained as a gain, before taxes and other investment expenses.

Hypothetical one-year illustration, not actual clients, fee quotes, typical costs, or a return forecast. Assumes equal gross portfolio returns and all stated service costs paid from the portfolios. Excludes taxes, underlying investment expenses, spending, and contributions. The RIA fee uses starting assets; actual billing terms vary. Actual services, costs, and results differ.

Under these assumptions, the Venice family comes out ahead by $400,000 for the year. The investments performed identically; the difference comes entirely from the cost of the service arrangements. The dedicated office consumed 12.5% of the Sarasota family's gross investment gain, compared with roughly 5.8% for the Venice family's combined advisory and professional costs. Different budgets or service needs would change that comparison.

The Sarasota office would need to deliver enough additional value to justify that difference. Dedicated control, substantial administrative work, or specialized support could provide a reason to pay more. In this example, however, the family's needs were already manageable through an RIA. The extra spending buys an organization the family doesn't need.

Costs still matter when markets weaken, although the two arrangements respond differently. 

An asset-based RIA fee generally falls as the value of the assets covered by the agreement falls, subject to billing dates, averaging methods, and minimum fees. Additionally, some advisers instead charge fixed or hourly fees.1, 6

If the Venice family's billable portfolio fell from $100 million to $80 million, the same 0.30% rate would imply an annual advisory cost of $240,000 at that lower value, before outside professional costs. That is an annualized comparison, not a calculation of the bill during the year of the decline. 

A dedicated office's payroll, systems, and administrative commitments don't automatically fall with the market, although bonuses, outsourced investment fees, or deliberate budget cuts may reduce some expenses.3 In a flat year, both arrangements would still draw on existing capital if their bills were paid from the portfolios. Money spent on unnecessary overhead is money unavailable for future investment growth, spending, or inheritance.

When a Dedicated Family Office Earns Its Cost

The calculation changes when managing the family's affairs becomes a full-time operation for several professionals. A family might own operating businesses, make direct investments in private companies, and have relatives living under different tax systems throughout the globe. Add a foundation and several generations sharing ownership, and decisions about distributions, reinvestment, and control become intertwined. That combination can support the case for a dedicated team.5

In a hypothetical family like this, an acquisition could require investment analysis, legal review, and cash planning at the same time that other family members need distributions. Those demands may recur throughout the year. Employees who know the entities, agreements, and decision-makers can maintain continuity across the work, with authority and responsibilities defined by the family.

A dedicated office becomes more compelling when the volume of work and need for direct control exceed what an RIA or a multi-family office can accommodate within its service model. Capabilities vary considerably, so complexity alone doesn't rule out either option. The justification is a sustained need for the family's own staff and systems, together with the resources and willingness to oversee them.5

The Multi-Family Office Middle Ground

Between that level of complexity and the more manageable needs of our Venice family lies a broad middle ground. A family may need deeper analysis, regular work across trusts, or support for several generations without generating enough work to justify a dedicated staff. A multi-family office can fit that situation. Several families share access to a team, its systems, and specialist resources. The arrangement can combine investment oversight, detailed planning, estate and tax coordination, reporting, and support across generations.

It can also operate as an RIA. “Multi-family office” describes the service model, while RIA describes registration. The special federal family-office exclusion applies to qualifying offices serving permitted family clients and meeting ownership, control, and other conditions; it isn't a general exemption for firms serving unrelated families.4

For example, one family may need extensive analysis of business-sale proceeds and estate options, while another may need ongoing work across several trusts and generations. Specialists may be employees or outside professionals. Clear responsibility for their work helps keep tax, estate, and investment decisions connected as the family's circumstances change.

A firm can offer conventional wealth management alongside a more extensive multi-family-office service. Families can then select a level of support suited to their circumstances, rather than paying for the broadest offering simply because it's available.

In Conclusion

Even at an ultra-high level of wealth, a dedicated family office may not be the most useful next step. The stronger reason to build one is often the complexity of your affairs and the work they require, rather than a particular net-worth figure. Does your family need its own staff to manage recurring decisions across businesses, trusts, and generations? Or could an RIA or multi-family office provide the depth of advice you need while leaving more of your wealth available for retirement, family, and future opportunities?

As our two families illustrate, paying for more infrastructure can leave less invested without necessarily improving the support you receive. A dedicated office can earn its cost when the work and need for control justify it; otherwise, a more focused arrangement may serve your family well.
