Running a family office costs $3-$10M annually – a steep price that makes sense only for portfolios exceeding $100M. Fixed expenses like staffing, technology, and compliance don’t scale with smaller portfolios, creating inefficiencies for those managing less than $100M. For example, a $3.2M annual cost translates to 3.2% of a $100M portfolio but drops to 0.64% for $500M.
Key takeaways:
- $3M/year minimum: Covers a lean setup with 4-5 staff and basic infrastructure.
- $5-10M/year: Adds advanced services like tax planning, estate management, and philanthropy.
- Hidden costs: Include tech upgrades, compliance, and staff turnover, adding $500K-$1M annually.
- Alternatives: Multi-family offices or virtual setups are cost-efficient for portfolios under $100M.
For portfolios above $200M, the cost-to-benefit ratio improves, offering privacy, control, and tailored services. However, smaller portfolios are better served by leaner models like multi-family offices or virtual setups, costing $400K-$700K annually.
Why Wealth Managers Say You Need $100M
Family Office Costs by Portfolio Size: Annual Expenses and Cost Ratios
Wealth managers often emphasize a $100 million minimum for family offices, and it all boils down to cost efficiency. To keep operating costs below 1% of assets, you’d need about $320 million, as the average annual operating costs for a family office hover around $3.2 million. With $100 million in assets, your cost ratio jumps to 3.2% – and that’s before you even start generating returns.
Assets vs. Operating Costs: Breaking Down the Numbers
The financial dynamics of family offices are heavily influenced by fixed costs. Whether you’re managing $50 million or $500 million, the core expenses – like a Chief Investment Officer, compliance systems, and tech infrastructure – don’t scale down with smaller portfolios.
Staffing alone typically takes up 50-60% of operating costs. On top of that, investment-related expenses, such as external manager fees and custody services, add another 43-50%. Technology and cybersecurity contribute 15-20%. These percentages remain steady regardless of portfolio size, but their impact on returns becomes more pronounced as assets shrink. This fixed-cost structure is why smaller portfolios struggle to achieve cost efficiency.
Cost Ratios at Different Portfolio Sizes
The numbers tell a clear story: larger portfolios are significantly more cost-efficient. For family offices managing less than $500 million, the average cost ratio is 105 basis points (1.05%). In contrast, those with over $1 billion in assets enjoy a much lower cost ratio of 36 basis points (0.36%) – a threefold improvement in efficiency. This stark difference explains why wealth managers are reluctant to recommend single-family offices for portfolios under $100 million.
| Portfolio Size | Annual Operating Cost | Cost Ratio | Break-even Return Needed* |
|---|---|---|---|
| $50M | $1.5M – $2.0M | 3.0% – 4.0% | 10% – 12% |
| $100M | $2.0M – $2.5M | 2.0% – 2.5% | 9% – 10% |
| $320M | $3.2M | 1.0% | 7% – 8% |
| $500M+ | $3.0M – $5.0M | 0.6% – 1.0% | 6% – 7% |
*Break-even return accounts for covering operating costs, inflation, and taxes without eroding the principal.
For smaller portfolios, like $50 million, the cost drag is steep – 3-4% – and requires returns of 10-12% just to break even. On the other hand, larger portfolios, especially those exceeding $1 billion, enjoy efficiencies that bring the cost ratio down to 0.36%. When compared to a multi-family office charging 0.5-2% of assets annually (roughly $250,000-$1,000,000), the math becomes clear: managing a single-family office with less than $100 million simply doesn’t add up.
Minimum Family Office Setup: $3M Per Year
Running even a streamlined family office requires a professional team and robust infrastructure, with costs hovering around $3 million annually. Unsurprisingly, staffing accounts for the largest portion – about 50–60% of the total budget. Let’s break down where the money goes, starting with personnel.
Staff Costs: The Biggest Slice of the Budget
Expect to spend $1.5 to $1.8 million annually on personnel for a lean operation. A core team typically includes four key roles.
- Chief Investment Officer (CIO): This is your priciest hire, with total compensation ranging from $337,000 to $600,000. The CIO oversees investment strategy, risk management, and external manager relationships. In larger offices, this figure can climb even higher, with median compensation reaching $821,000.
- Investment Analysts: Budget $200,000 to $400,000 for one or two analysts who handle due diligence, explore alternative investments, and monitor portfolio performance. A small investment team – comprising a CIO, two analysts, and a data analyst – can easily exceed $1 million in combined compensation and benefits.
- Operations Manager or CFO: This person manages financial accounting, tax compliance, reporting, and vendor relationships.
- Administrative Support: Handles day-to-day office operations and coordinates family-related matters.
Once staffing is covered, the remaining budget focuses on infrastructure and professional services.
Infrastructure: Office, Technology, and Professional Services
The rest of the budget – $1.2 to $1.5 million – goes toward office space, technology, and external expertise.
- Technology: Allocating 15–20% of your budget ($450,000 to $600,000) ensures access to essential tools like portfolio management systems, which alone can cost $50,000 to $200,000 annually. This also includes cybersecurity, data management, and hardware.
- Office Space: Facilities will eat up another 5–10% of your budget ($150,000 to $300,000), with costs varying significantly based on location. Prime markets like New York or London will be on the higher end, while secondary cities offer more affordable options.
- Professional Fees: Legal, tax, and audit services typically add another $100,000 to $500,000 annually. Even with in-house staff, you’ll need external advisors for complex tasks like estate planning, structuring, and regulatory compliance. Outsourcing these specialized services makes more sense than hiring full-time experts for occasional needs.
Total Annual Cost for a Basic Family Office
When you combine staffing ($1.5–1.8M) with infrastructure and professional fees ($1.2–1.5M), the total comes to about $3 million per year. This translates to a 3% annual cost ratio for managing a $100 million portfolio.
Full-Service Family Office: $5–10M+ Per Year
Expanding from the basic $3M setup, a full-service family office offers a broader range of financial and lifestyle services. While the minimal setup focuses on fundamental investment needs, this advanced structure incorporates areas like tax planning, estate management, philanthropy, and lifestyle coordination. These additional services drive annual costs into the $5–10M+ range.
Additional Staff for Advanced Services
To deliver these enhanced services, new specialized roles are required. Key positions include:
- Tax Director: $250K–$400K
- Estate Administrator: $200K–$350K
- Philanthropy Officer: $150K–$300K
- Family Office COO: $250K–$400K
- Concierge/Lifestyle Manager: $120K–$200K
Together, these roles add $970K–$1.65M to payroll costs. Additional administrative support, costing $150K–$300K, is also necessary. Including the team from the minimal setup, total staffing expenses rise to approximately $2.5–3.5M annually.
Expanded Infrastructure Needs
With a larger team and more complex operations, infrastructure requirements grow significantly. Office facilities must accommodate 10–15 employees, leading to annual costs of $200K–$500K. Technological investments increase to $200K–$400K, covering high-end systems for philanthropy management, multi-entity reporting, and robust cybersecurity.
Professional services also scale up. Managing multiple trusts, foundations, and international structures can push legal and tax advisory fees to $500K–$1M annually, especially during significant estate planning or asset acquisitions. Insurance costs rise as well, with premiums for high-value properties, such as oceanfront estates, exceeding $50K annually.
Total Annual Costs for Full-Service Operations
When expanded staffing ($2.5–3.5M) and infrastructure ($1.5–2.5M) are combined, total annual expenses for a full-service family office typically range from $4–6M. For families managing $1B+ in assets with teams of 25+ employees, costs can climb to $8–10M. These figures represent operational costs only and do not include external investment management fees. While the expenses are substantial, they provide the benefits of enhanced control, comprehensive wealth management, and tailored services for affluent families.
Hidden Costs That Aren’t in Initial Budgets
When founders estimate the costs of running a family office, they often focus on obvious expenses like salaries and office space. However, there’s a host of hidden costs that can add anywhere from $500,000 to $1 million each year, pushing total expenses above $3 million. These hidden costs only add to the fixed expenses already accounted for.
Technology Maintenance and System Upgrades
The initial costs for tools like Bloomberg or portfolio management platforms are just the tip of the iceberg. Technology expenses typically make up 15–20% of operating costs, but many founders fail to plan beyond the first-year implementation. Expect to allocate an additional $100,000 to $300,000 annually for system upgrades, data feeds, and integration work.
"Investing in digital tools is only cost-effective if the tools are used fully. Many family offices license expensive platforms but fail to integrate them, relying instead on spreadsheets and manual workflows." – Anders Viskum, CEO Nordics & Co-founder, Aleta
Underutilized platforms are a double hit to your budget – you’re paying for advanced software while still relying on manual processes to handle data from custodians, private equity holdings, and real estate investments. And technology isn’t the only area where costs can creep up.
Regulatory Compliance and Audits
Even though single-family offices often avoid SEC registration, compliance costs remain a significant burden. State registrations, audits, and ongoing monitoring can cost between $100,000 and $300,000 annually. On top of that, legal fees for basic filings average $50,000 per year. If you’re restructuring estates or setting up a foundation, those legal costs can skyrocket to $250,000 in a single year. It’s crucial to account for both routine compliance expenses and these occasional, high-cost events.
Staff Turnover and Replacement Costs
Replacing key employees can be surprisingly expensive. For instance, hiring a Chief Investment Officer (CIO) with a $500,000 salary often involves recruiting fees of 20–30% of that salary – adding $100,000 to $150,000 per hire. With 59% of family offices reporting rising staff costs due to competition for talent, these expenses are becoming harder to ignore. Beyond recruitment costs, losing a senior team member also means losing institutional knowledge, which can create operational challenges and further strain your budget.
Performance Pressure and Scope Expansion
High operating costs often lead to pressure to show value, which can push family offices to expand their services. This might include hiring specialists, managing philanthropic efforts, or diving into alternative investments that require new expertise. Each of these adds to annual expenses. For example, launching a foundation might mean hiring a philanthropy officer (at $150,000–$300,000), purchasing specialized reporting software, increasing legal oversight, and enhancing compliance measures. These added commitments can significantly inflate your operating budget, making careful financial planning even more critical.

When the Costs Actually Make Sense
The ROI Calculation: Family Office vs. Multi-Family Office
Let’s break it down: if you’re managing $100 million in assets and your dedicated family office costs hover around $4 million annually, you’re looking at a cost rate of 4%. Compare that to the typical 2% charged by multi-family offices, and you’ll see why the numbers matter. To justify the extra expense, your dedicated office needs to deliver returns that outpace the lower-cost alternative. Even a modest 2% difference in net returns can lead to a massive gap in wealth accumulation over a decade.
Here’s where scale works in your favor. As your assets grow, the cost efficiency improves. For instance, a full-service family office might cost $5 million a year for a $200 million portfolio, translating to a 2.5% cost rate. Scale that up to $500 million, and the annual cost of $8 million drops the rate to about 1.6%. At this level, a dedicated family office starts to compete with the pricing of multi-family offices.
This cost-benefit equation ties directly to the strategic decisions you’ll make about asset management, which we’ll explore in greater detail later.
Non-Financial Benefits: Privacy, Control, and Customization
Of course, the numbers only tell part of the story. Family offices bring a range of non-financial perks that can be just as compelling.
For starters, single-family offices create a secure, "closed-loop" environment that significantly reduces the risk of cyber breaches. This is a big deal for founders with proprietary technology or sensitive financial data. With one-quarter of family offices reporting exposure to cyber breaches or fraud, having tight control over who can access your financial information is invaluable.
Another advantage? Flexibility. Unlike multi-family offices bound by standardized processes, a dedicated family office can pivot quickly – whether it’s focusing on direct investments, philanthropic efforts, or other priorities.
And let’s not overlook governance. Establishing strong governance practices – like regular family meetings, succession planning, and next-gen education – pays off in the long run. These investments can prevent costly conflicts and legal disputes while preserving family harmony. Even a modest annual commitment to governance can protect your wealth and ensure your legacy thrives for generations.
What to Do at Each Asset Level
Managing family office costs effectively starts with understanding how asset thresholds influence your options.
Decision Guide by Portfolio Size
For portfolios around $50 million, setting up a single-family office doesn’t make financial sense. The overhead costs of maintaining an in-house operation can significantly cut into your returns. Instead, many founders opt for multi-family or virtual office models, which typically cost between $400,000 and $600,000 annually, keeping cost ratios manageable at 1%–2%. Even at $75 million, fixed overheads remain a concern, and most families stick with virtual or multi-family setups to cover essential services without the burden of a full-time team.
Once you hit the $100–150 million range, things start to shift. A lean single-family office becomes a practical option. With a small team of 1–3 generalists, you can keep annual expenses between $1 million and $1.5 million, maintaining a cost ratio of about 1%. However, some families in this range still prefer the shared infrastructure of a multi-family office for added flexibility and cost-sharing benefits.
When assets exceed $200 million, a dedicated single-family office becomes more feasible. Budgets of $2 million to $3 million (about 1%–1.5% of assets) can support a fully staffed team, offering centralized control and tailored services. For portfolios of $500 million or more, economies of scale kick in. With annual costs ranging from $2.5 million to $7.5 million, you can afford a robust team, including roles like Chief Investment Officer, tax director, and specialized analysts, while keeping cost ratios competitive.
Lower-Cost Alternatives: Virtual and Embedded Models
If your assets haven’t reached these thresholds, there are more affordable options to consider until you’re ready for a dedicated setup.
- Virtual Family Office: This model uses a high-level coordinator to manage outsourced specialists. Annual costs typically fall between $400,000 and $700,000, with additional expenses for technology platforms (ranging from $50,000 to $200,000 annually) to handle reporting and compliance. This approach offers oversight without the need for permanent staff.
- Embedded Family Office: If you own an operating business, you can integrate family wealth management into your existing infrastructure. For example, your CFO or senior staff could oversee wealth management, supported by an investment analyst and administrative staff. This setup adds $300,000 to $500,000 annually to your business costs, keeping total family office expenses in the $500,000 to $800,000 range. However, combining personal and business finances may bring regulatory challenges.
Ultimately, the best model for you depends on your asset size, long-term goals, and how much you’re willing to balance dedicated oversight with cost efficiency.
Conclusion
Running a family office typically costs between $3 million and $10 million annually, depending on its scope. Staffing alone can consume 50–60% of the operating budget, with the rest allocated to technology, compliance, and professional services. These recurring expenses play a significant role in long-term wealth management, making it essential to understand and plan for them as part of your broader strategy.

On average, family office costs are benchmarked at 1–2% of assets under management. It’s important to compare these all-in expenses against leaner alternatives, such as virtual or embedded offices, to determine whether the added control and customization of a full-service family office truly justify the investment.
Approach the decision to establish a family office with the same analytical mindset you used to grow your business. Apply the same systematic planning and rigor to ensure your family office aligns with your long-term goals.

- Charles Simonds, Family Office Consultant, Bank of America Private Bank
The key is to quantify total costs, objectively compare alternative setups, and evaluate whether the benefits – like centralized control, privacy, and legacy planning – are worth the expense.
For founders with less than $150 million in liquid assets, leaner models such as virtual or embedded offices often strike the right balance between control and cost-efficiency, as discussed earlier. For those managing larger asset bases, the decision shifts from affordability to determining whether the advantages of consolidated control and long-term legacy planning are worth the higher investment.
FAQs
What are the main benefits of having a family office for portfolios exceeding $200 million?
For portfolios exceeding $200 million, a family office provides several key benefits. These include enhanced control and privacy in managing finances, personalized strategies for multi-generational wealth planning, and expertise in navigating complex financial structures, such as cross-border tax considerations or philanthropic endeavors.
Moreover, larger portfolios benefit from more competitive operating costs. Family office expenses typically range from 1.6% to 2.5%, which becomes proportionally more cost-effective as assets grow. At the same time, they offer tailored services and long-term strategies designed to safeguard and expand wealth.
How can tech founders efficiently manage family office costs for portfolios under $100 million?
Tech founders with portfolios under $100 million can keep family office costs under control by adopting strategies that align with their specific needs. One smart approach is opting for a virtual family office or an embedded family office. These models typically cost between $400,000 and $800,000 annually – far less than the $3 million or more a traditional family office might demand. By utilizing fractional roles, outsourced services, and flexible infrastructure, these setups help reduce overhead while still covering essential operations.
Another effective cost-saving measure is outsourcing specialized tasks like tax preparation, legal services, and investment reporting. This allows founders to maintain high-quality results without the expense of in-house teams. Additionally, choosing scalable, cloud-based technology over pricey, custom-built systems can further streamline expenses. Regularly reviewing the family office’s scope and budget ensures resources are used wisely, helping to avoid unnecessary costs while staying focused on long-term financial objectives.
What unexpected costs should tech founders consider when running a family office?
Running a family office involves more than just managing investments – it comes with a range of hidden costs that can quickly stack up. For instance, technology expenses are a significant factor. Setting up and maintaining systems like portfolio management tools can be pricey, often surpassing $100,000 annually.
Then there’s the matter of regulatory compliance, which isn’t cheap either. Even family offices exempt from SEC registration might face yearly compliance costs ranging from $100,000 to $300,000.
Another major expense to consider is staff turnover. Replacing senior roles, such as a Chief Investment Officer, can be particularly costly, with recruiting fees alone reaching 20-30% of the individual’s salary. On top of this, there are other ongoing expenses like maintaining high-end infrastructure, securing professional services, and ensuring proper insurance coverage. While these are essential for smooth operations, they can significantly inflate the annual budget.
Understanding these hidden costs is crucial for effective financial planning and keeping the family office running efficiently.
