The basis-point quote is applied marginally, the minimum turns it into a fixed fee for small or ageing funds, and a third of the bill sits outside it.
A private fund administrator's fee is usually a tiered basis-point charge on commitments or NAV, subject to an annual minimum, plus fixed charges per investor, per entity and per service. On an illustrative 600 million fund, tiers of 6, 4 and 3 basis points give 280,000, and 138,000 of add-ons bring the bill to 418,000 a year, 6.97 basis points, half as much again as the tiers alone. The effective rate climbs to 24.00 basis points late in life, when the minimum takes over.

Administrators quote in basis points because managers compare in basis points, but the quote is rarely the bill. The headline schedule is applied marginally, tier by tier, and most of the variability sits outside it: investor counts, feeder and blocker entities, financial statements, regulatory reporting. A COO who budgets on the headline rate will be wrong twice, once on the tiers and once on everything else, and the error grows as the fund shrinks.
| Term | Value |
|---|---|
| Fee base | Commitments in the investment period, NAV after |
| First 250 million | 6 bps |
| Next 250 million | 4 bps |
| Above 500 million | 3 bps |
| Annual minimum on the basis-point fee | 150,000 |
| Investor services, 120 investors at 400 | 48,000 |
| Two feeder and blocker entities at 25,000 | 50,000 |
| Annual financial statements and audit support | 30,000 |
| FATCA and CRS reporting | 10,000 |
| Fixed add-ons | 138,000 |
Tiered fee = Σ (part of the base in each tier × that tier's rate)
Basis-point fee charged = MAX(tiered fee, minimum)
Total = basis-point fee charged + fixed add-ons; effective rate = total ÷ base
In Excel, with the base in B1 and tier ceilings of 250 and 500 million: =MAX(150000, MIN(B1,250e6)*0.0006 + MAX(0,MIN(B1,500e6)-250e6)*0.0004 + MAX(0,B1-500e6)*0.0003). Pro rate by days if the fee base changes mid-year, as it does when the investment period ends.
| Line | Base | Rate | Fee |
|---|---|---|---|
| First tier | 250,000,000 | 6 bps | 150,000 |
| Second tier | 250,000,000 | 4 bps | 100,000 |
| Third tier | 100,000,000 | 3 bps | 30,000 |
| Basis-point fee (above the minimum) | 4.67 bps | 280,000 | |
| Fixed add-ons | 138,000 | ||
| Total | 600,000,000 | 6.97 bps | 418,000 |
The fund pays 418,000 a year, 6.97 basis points of commitments. The tiers alone are 4.67 basis points, below the first-tier rate, because only the first 250 million pays 6. The add-ons are a third of the bill, and they are the part that moves: every new investor, every new blocker, every extra report changes it, and none of them appears in the basis-point quote. An investor with 10,000,000 committed bears about 6,967 of it each year, since administration is normally a fund expense.
Rebuild the invoice from the schedule every quarter rather than checking it against last quarter. The base on the invoice should agree to the commitments or NAV in the fund's own records, the tier split should be recomputed, and each add-on should tie to a count the fund controls: investors on the register, entities on the structure chart, reports actually delivered. A total that merely looks similar to the prior quarter proves nothing.
The minimum of 150,000 equals the first-tier rate on exactly 250 million. Below that base the minimum binds and the schedule stops being a percentage at all; it becomes a fixed fee, which is what the administrator priced in the first place.
| Base | Tiered fee | Charged after minimum | Total with add-ons | Effective bps |
|---|---|---|---|---|
| 150 million commitments | 90,000 | 150,000 | 288,000 | 19.20 |
| 300 million commitments | 170,000 | 170,000 | 308,000 | 10.27 |
| 600 million commitments | 280,000 | 280,000 | 418,000 | 6.97 |
| 1,000 million commitments | 400,000 | 400,000 | 538,000 | 5.38 |
| Late life, NAV 450 million | 230,000 | 230,000 | 368,000 | 8.18 |
| Late life, NAV 120 million | 72,000 | 150,000 | 288,000 | 24.00 |
Two patterns follow. Small funds pay a much higher rate: the 150 million fund pays 19.20 basis points for the same work as the 600 million fund, because the minimum and the add-ons do not scale down. And every fund becomes a small fund. Once the base switches to NAV and realisations shrink it, the bill falls only until the minimum binds, then stays near 288,000 while NAV keeps falling, so the effective rate rises to 24.00 basis points. A budget that carries the investment-period rate into the harvest years is wrong in the years when investors watch expenses most closely.
Compute the tiered fee marginally, apply the minimum, add the fixed charges and divide by the base: 418,000 and 6.97 basis points here, rising to 24.00 basis points as NAV runs off. What a lower quote actually saves once rework and data costs are counted is a separate question, worked in how much a cheaper fund administrator actually saves. The free workbooks for this case include the administrator scorecard and the capacity model that sit beside the fee.
It depends heavily on fund size and structure, so compare totals rather than headline rates. On the illustrative schedule, the same administrator costs 19.20 basis points a year on a 150 million fund, 6.97 on a 600 million fund and 5.38 on a 1,000 million fund, because the minimum and the per-investor and per-entity charges do not scale with assets.
Because the base usually switches from commitments to NAV and shrinks as investments are sold, while the minimum and fixed charges stay. On a 120 million NAV the illustrative tiers give 72,000, the 150,000 minimum applies instead, and with 138,000 of add-ons the bill is 288,000, or 24.00 basis points.
In most private funds administration is a fund expense borne by investors, as the LPA allows, though some managers absorb part of it. On the illustrative 600 million fund, an investor with 10,000,000 committed bears about 6,967 a year of the 418,000 total.
