Fund of Funds (FoF) Double-Fee Layer
The Formal Definition
The compounding operational fee drag that occurs when an investment fund charges its own management fee on top of the underlying expense ratios of the individual third-party funds it holds in its portfolio.
Total Fee Drag (%) = Parent Fund Management Wrap Fee + ∑ [ Asset Allocation Weight_i × Sub-Fund Expense Ratio_i ]
Cole Barrett's Reality Check
The Unvarnished Bottom Line"A 'Fund of Funds' is one of the easiest ways for wealth managers to charge double for basic asset allocation. They take your money, charge you a 1.25% management fee, and then simply buy four other mutual funds that each charge another 0.85%. By the time you add it all up, you're paying over 2% a year just to have someone own standard funds for you."

Examining the real numbers for: An investor allocating $200,000 into a diversified global asset allocation strategy over a 15-year period
| Execution Metric | Self-Directed Multi-Asset ETF Portfolio | Advisory Fund-of-Funds Structure |
|---|---|---|
| Fee / Rate | $0 commission | Wrap fee |

| Execution / Status | Invested capital grew with minimal fee drag; total annual expense was just $120 on $200,000 | Faced an ongoing 2.05% total expense drag every single year regardless of market performance |
| Total Cost / Result | Maximized compounding returns by eliminating fee layers | Surrendered nearly a quarter of potential wealth to layered fees |
How Brokers Weaponize This Term
Always check the 'Acquired Fund Fees and Expenses' (AFFE) line item on any mutual fund or target-date prospectus. That line reveals the underlying fees of the child funds, which are often left out of the headline management fee.

Why do institutional investors ever use Fund of Funds?
They are sometimes used in private equity and venture capital to gain access to elite, closed-door hedge funds that require $10M+ minimums that smaller investors couldn't access on their own.
Are target-date retirement funds considered Fund of Funds?
Yes. Most target-date retirement funds are structured as fund of funds, holding broad stock and bond index funds. However, low-cost providers price them with total expense ratios under 0.10%.
