What is the minimum net worth to have a family office? There is no legal minimum. A dedicated single family office is commonly associated with about $100 million or more in net worth, per Charles Schwab and NerdWallet. Multi family offices most often work with families from around $25 million to $30 million, per Schwab and Cresset.

What is the average cost of a family office? J.P. Morgan Private Bank's 2026 Global Family Office Report, based on 333 single family offices, puts average annual operating costs at $0.9 million for offices with $250 million or less in assets, rising to $6.6 million for offices with $1 billion or more. Campden Wealth and RBC's 2026 North America Family Office Report puts the median at about $2.75 million a year.

The thresholds are economic. This article covers the numbers people cite, where each comes from, why they exist, and what to do if you are below them. All figures are from the sources named, read in October 2026.

Family office minimum net worth by structure

Structure Commonly cited minimum What you get
Single family office (SFO) $100 million+ in net worth (Schwab, NerdWallet); some advisers set the bar at $500 million or more for a fully staffed office (LegalClarity) Dedicated entity and staff serving one family
Multi family office (MFO) Around $25 million to $30 million (Schwab, Cresset, Creative Planning) Shared professional team, fee usually based on assets
Outsourced or virtual family office Around $10 million (NerdWallet) A coordinated network of outside providers, usually with one coordinator

These are conventions, and views vary. Kiplinger puts the practical financial minimum at $60 million to $200 million of net investable assets. Asena Advisors describes $50 million as the generally understood minimum threshold.

LegalClarity says most families need at least $100 million before a single family office makes financial sense, and that many professionals now recommend $500 million or more for a fully staffed operation. Schwab notes that many in the business say a full single family office with eight or more employees should be built only once a family is worth at least $1 billion.

What is the average cost of a family office?

The best evidence comes from the large annual surveys run by private banks and research firms. Each measures something slightly different, so here is what each one found, with its sample and date.

  • J.P. Morgan Private Bank, 2026 Global Family Office Report (333 single family offices across 30 countries). Average annual operating costs by assets under supervision: $0.9 million for $250 million or less; $1.7 million for $250 million to $500 million; $3.3 million for $501 million to $999 million; and $6.6 million for $1 billion or more.
  • Campden Wealth and RBC, The North America Family Office Report 2026 (155 family offices, representing families worth from $100 million to more than $10 billion). Median operating costs of about $1 million each for investment-related and administrative functions, $0.5 million for advisory and $0.25 million for family services, for a total median of approximately $2.75 million. Respondents expect costs to rise 5 percent in 2026.
  • Campden Wealth and RBC, The North America Family Office Report 2025 (141 North American family offices, surveyed April to August 2025). Average operating costs, excluding investment-related fees, of $4.3 million. Offices with less than $250 million in assets averaged $1.1 million, equal to 62 basis points of assets; offices with more than $1 billion averaged $9.8 million, equal to 35 basis points.
  • UBS, Global Family Office Report 2025 (317 family offices). The global average pure cost of running a family office in 2024 was 41.1 basis points of assets under management, and 35.1 basis points for offices with more than $1 billion.

Read together, the surveys tell a consistent story: the dollar cost rises with size, and the cost as a percentage of assets falls. That pattern is the reason the minimums exist.

Why the thresholds exist: operating cost vs basis points

A family office is largely a fixed-cost operation, and the question is what those fixed costs represent as a percentage of your wealth. Schwab puts the annual cost of a single family office at about 1% to 3% of a $100 million net worth, which is why it treats $100 million as the general rule of thumb.

Simple arithmetic with a sourced figure shows the curve. Take the $1.1 million average cost of the smallest offices in the 2025 Campden Wealth and RBC North America survey:

  • On $50 million, $1.1 million is 2.2% of assets per year.
  • On $100 million, it is 1.1%.
  • On $300 million, it is about 0.37%.

For comparison, Schwab states that investment management from a multi family office generally costs between 0.30% and 0.70% of assets under management. Below roughly $100 million, a shared model usually wins on cost; above it, a dedicated office becomes a defensible line item, and the decision turns on control, privacy and complexity. LegalClarity makes the same point with its own example: $1 million a year is 2% of $50 million and 0.20% of $500 million.

Complexity moves the threshold too. A family with operating businesses, real estate in several states, trusts and a foundation may need family office services sooner than a wealthier family whose assets sit in index funds. Kiplinger and Asena Advisors both list complexity alongside asset size as a deciding factor.

Cost explains the floor; complexity decides where you personally land relative to it.

Single, multi and outsourced family offices: what each model buys

Single family office at $100 million+. The family owns the entity, hires the staff, and controls everything: investment policy, privacy, hiring, and philanthropy. Direct investing is a major motivation for many families.

Our primer on what a family office is covers the full service menu, and our guide to how family offices make money explains how they are funded and who pays for what.

Multi family office from around $25 million to $30 million. The family buys a share of a professional team. NerdWallet puts multifamily office costs at generally 0.40% to 0.70% of assets under management, which for a family with $50 million means $200,000 to $350,000 a year.

The trade-off is standardization: the family is one client among several. See our comparison of the single family office vs multi family office models for how families choose.

Outsourced or virtual family office from around $10 million. NerdWallet describes an outsourced family office as a group of professionals employed by third parties, such as law firms, banks or accounting practices, with one person typically coordinating the work. It puts the cost at about 0.2% to 1.25% of assets under management and the recommended minimum at about $10 million.

Multi family office minimum net worth

Multi family offices set their own minimums, and the firms that publish guidance on their sites cluster around the same range. As of October 2026:

  • Cresset, which offers family office services, states that clients of a multi-family office typically have a minimum net worth in excess of $25 million.
  • Creative Planning states that a multifamily office is usually best for clients with a minimum net worth of around $25 million, and its comparison table lists a typical multifamily office minimum of $10 million to $25 million.
  • Commons Capital states that most multi-family offices start looking for a minimum of around $25 million to $30 million in investable assets, and that some are flexible.

Schwab adds that most multi family offices have a minimum based on assets under management, net worth or fee level, with most working for families with over $30 million in net worth. Minimums differ by firm and by service, so ask each firm directly.

Family office alternatives below the minimum net worth

Below the multi family office range there are plenty of good options:

  • Private wealth management. Commons Capital's comparison lists typical minimums of $1 million and up for a traditional wealth manager and $5 million and up for a private bank. Our comparison of a family office vs a private bank explains who does what.
  • An outsourced family office. A coordinated team of outside providers, as described above.
  • An OCIO (outsourced chief investment officer). Institutional-style portfolio management without hiring a CIO.
  • Trusts and a personal holding company plus strong advisers. Many families start with trusts and a simple holding entity, appoint a lead adviser, and formalize further over time. Our guides on family office vs trust and how to name a family office cover the first steps.
  • Start with governance. A family charter, an investment policy statement, and an annual family meeting bring much of a family office's discipline at any wealth level.

Families in this range still show up in the market as investors, which is why they appear in investor research workflows. Capital raisers researching this segment can benchmark the landscape with our family office statistics roundup, and our guide to the best family office databases explains how these offices get catalogued once they formalize.

The market keeps widening

Outsourced and shared models give families more ways to get family office services below the dedicated-office threshold, and the number of single family offices keeps growing. CNBC, citing a Deloitte Private report, reported in September 2024 that the number of single family offices is expected to rise from 8,000 to 10,720 by 2030, with assets expected to top $5.4 trillion by 2030.

The practical takeaway: treat $100 million and $25 million to $30 million as pricing signals. They tell you which model the economics favor at your asset level, and each model above is a legitimate family office arrangement.
