Asset Management Fees: AUM vs. Invested-Equity Basis

Why the basis matters more than the rate — and how to read the basis line in a PPM.

6-min read

The asset management fee — usually quoted as a single percentage on the cover of a PPM — is the single biggest source of fee drag in a typical private fund. It's also the line where the basis matters far more than the rate. A 1.5% fee on the wrong basis is materially worse than a 2% fee on the right one.

The four bases you'll see

Committed capital
The fee is charged on the LP's total commitment, regardless of how much has actually been called. Sponsor-friendly during the investment period (the GP is paid on capital that hasn't been deployed yet); LP-friendly afterward (the GP can't inflate the basis by holding investments longer).
Invested equity
The fee is charged on capital actually deployed into deals — not commitments, not AUM. Most LP-favorable. The GP only earns the fee on capital that's working.
Assets under management (AUM)
The fee is charged on the gross asset value, including leverage. Most sponsor-friendly; a 60% LTV deal effectively triples the basis compared to invested equity. Common in real estate funds where leverage is structurally high.

Why the basis matters more than the rate

Take a $100M real-estate value-add fund deploying $50M of LP equity into deals with 60% LTV. Same 1.5% fee, four bases:

Annual fee, $100M committed real-estate fund
BasisNotional ($M)Annual fee ($M)
Invested equity ($50M deployed)$50.0$0.75
Committed capital ($100M total)$100.0$1.50
NAV (assume 1.2× mark on equity)$60.0$0.90
AUM (60% LTV → $125M asset value)$125.0$1.88

Annual fee dollars range from $750k to $1.88Mdepending on the basis — a 2.5× spread on the same headline rate. Over a 5-year hold the cumulative difference is bigger than the typical acquisition fee, the disposition fee, and the GP's carry on a borderline deal, combined.

Step-downs

Most LPAs include a fee step-down after the investment period ends. The fee continues, but on a reduced basis or at a lower rate. Common patterns:

What to ask

  1. What's the basis during the investment period? Invested equity is the LP-favorable answer.
  2. What's the basis after the investment period? Look for it shrinking as deals exit, not staying static.
  3. How does the fee handle write-offs? The most LP-friendly structure removes write-offs from the basis immediately. Sponsor-friendly LPAs continue to charge on impaired investments.
  4. Are there management-fee offsets for transaction fees (acquisition, disposition, financing)? See Acquisition Fees for why these matter.

The biggest single thing you can do to evaluate a fund's fee load honestly is to convert every fee to a dollar amount on your actual commitmentover the actual hold period. Rate × basis × time, not just the headline rate. That's the number that comes out of your eventual proceeds.
