Every private-market fund, regardless of wrapper, decomposes into the same four layers of cost. Train yourself to fill in all four for any product, and you will never again be surprised by a fee. The trap is that the marketing material almost always shows you Layer 1 — sometimes only part of it — and lets you assume the rest is small.
The four cost layers of any private-market fund
| Layer | What it pays for | Where it hides |
|---|
| 1. Manager compensation | Base management fee plus performance fee (carried interest for PE/VC; incentive fee for BDCs and credit funds). | The management fee is disclosed; the performance fee is frequently excluded from the stated expense ratio and from “acquired fund fees.” This is the single most under-counted cost. |
| 2. Fund operating costs | Organizational and offering costs, administration, custody, audit, legal, transfer agency, and acquired fund fees and expenses (AFFE) when the fund holds other funds. | Buried in “Other Expenses” and “AFFE” lines. Small at scale, but large in a fund’s early years when the asset base is thin. |
| 3. Distribution & intermediary | Upfront sales loads or placement fees, ongoing shareholder-servicing and distribution (trail) fees, platform and feeder-fund fees, and manager-paid placement commissions. | Varies entirely by share class and access channel. This is the layer you, the advisor, most directly control — and the one this paper focuses on. |
| 4. Financing / leverage | Interest expense on the fund’s borrowings. A strategy cost, not a fee, but it flows through the client’s net return. | Shown as “interest payments on borrowed funds.” It can dominate a BDC’s total-expense line and make two funds look far apart on cost when the difference is really leverage. |

Two disciplines follow from this table. First, always separate Layer 4 from Layers 1 through 3. A non-traded BDC may report a total annual expense of 8% or more, but a large slice of that is interest on leverage — a cost of the strategy the client is buying, not a fee for access or management. Comparing a levered credit fund’s all-in expense to an unlevered equity fund’s is comparing apples to a ladder. Second, always add the performance fee back in mentally. A stated 3.40% expense ratio that excludes a 12.5% incentive fee or a 20% carry is not a 3.40% product.
Illustration: the headline-fee mirage
A recently launched public-plus-private interval fund-of-funds leads its marketing with a 0.10% management fee. Decomposed into the four layers, the launch-phase reality looks very different:
| Layer | Component | Rate |
|---|
| 1a. Management fee | Waived for ~3 yrs, no clawback | 0.10% |
| 2a. Fund operating | Other expenses (launch estimate on a small asset base) | 2.56% |
| 2b. Acquired-fund fees | Acquired fund fees & expenses (AFFE) | 0.68% |
| Stated all-in (before performance fees) | ~3.40% |
| 1b. Performance fee | Underlying private-fund carry (10–15%, excluded from AFFE) | not shown |
Source: fund prospectus and SEC filings, July 2026, as analyzed in BIP’s WVB interval fund review. The 0.10% headline is real; so is the roughly 34x gap between it and the all-in cost before carry.
The rest of this framework is, in effect, a set of tools for filling in those four layers quickly and correctly — first by fund structure, then by access channel (direct versus platform), then by share class.
