Is Your Family Office Eroding Your Wealth? Key Metrics to Measure Success
Managing wealth through a family office can be challenging. Discover the importance of measuring investment returns and how to optimize family wealth management.

Building a fortune is a remarkable achievement, yet preserving and managing that wealth through a family office can be an entirely different challenge. Many affluent families establish family offices to ensure their financial legacy, but without rigorous performance measurement, they risk undermining their wealth over generations. Understanding this balance is crucial for long-term financial health and legacy preservation.
Michael W. Sonnenfeldt, a seasoned entrepreneur and philanthropist, emphasizes the necessity of measuring returns in family offices, drawing on his extensive experience with successful individuals. He argues that many wealthy families fail to adequately assess their investment performance, potentially leading to a gradual erosion of their financial legacy. This issue is particularly pressing as family offices can often lag behind more straightforward investment strategies, such as index funds, which have historically yielded better returns.
The Wealth Creation vs. Wealth Management Dichotomy
Wealth is often built through concentrated efforts and high-risk ventures, typically by entrepreneurs who are adept at identifying and seizing opportunities. However, the shift to a family office marks a transition from wealth creation to wealth management, which operates under different principles. While an entrepreneur might achieve returns upwards of 21%, as Sonnenfeldt has done, family offices frequently see compounded returns hovering between 6% and 7% annually. This discrepancy is crucial to understand.
The Compounding Effect
Compounding interest underscores the importance of even slight differences in returns over time. For instance, a dollar invested at a 6% return grows to approximately $5.74 over 30 years, whereas the same dollar at a 10% return (the historical average for U.S. stock markets) would swell to around $17.50. The stark contrast between these figures illustrates the potential wealth that can be forfeited due to underperformance in family office investments.

Identifying Weaknesses in Family Office Performance
Despite the expertise that many individuals bring to their family offices, the transition to managing wealth often reveals a lack of understanding regarding portfolio performance. Many family offices prioritize metrics like account values and asset allocations without digging deeper into actual returns. This oversight can lead to a false sense of security and may prevent families from recognizing when their wealth is being eroded.
Common Pitfalls in Wealth Management
- Ignoring Performance Metrics: Without a clear understanding of investment performance, families may miss crucial opportunities for improvement.
- Overconfidence in Expertise: Successful entrepreneurs may assume that wealth management will be as straightforward as wealth creation, which is often not the case.
- Failure to Diversify Wisely: Family offices sometimes focus on complexity rather than effective diversification strategies that could yield higher returns.
Strategies for Effective Family Office Management
To counteract these issues, families should adopt a more disciplined approach to measuring success and managing their wealth. Sonnenfeldt suggests several strategies to help families navigate the complexities of wealth management effectively.
1. Measure Performance Across Time Horizons
Families should track their investment returns over various timeframes—short, medium, and long-term. This approach provides a more comprehensive view of performance and helps identify potential risks and liquidity issues. Establishing frameworks that categorize investments by their liquidity and risk levels can reveal strengths and weaknesses often overlooked in traditional reports.
2. Acknowledge the Skill Gap
Wealth management requires a different skill set than entrepreneurship. While successful entrepreneurs excel in identifying lucrative opportunities, family offices often find themselves competing in the global marketplace without the same level of unique advantage. Families should recognize the need for exceptional investment talent when managing their portfolios.
3. Define Clear Objectives
Before diving into investment strategies, families must clarify their goals. Key questions include whether future generations prefer to maintain unified assets or manage them independently and what role heirs will play in governance. Addressing these questions early on can significantly influence a family office's success.

4. Focus on Measuring What Matters
Just as businesses thrive on metrics, family offices should prioritize measuring their returns effectively. By consistently tracking performance across different time horizons and investment categories, families can identify weaknesses and make informed decisions about their asset management strategies.
Key Takeaways
- Measure investment returns to avoid the erosion of wealth over generations.
- Understand that wealth management requires different skills than wealth creation.
- Define clear objectives and governance structures for family offices.
- Track performance across multiple time horizons for comprehensive insights.
