Fund economics — fees, carry, and what PE optimizes for

#The two-part fee, precisely

A PE firm (the General Partner, or GP) is typically paid two things by its Limited Partners: an annual management fee, commonly around 2% of committed capital, paid regardless of fund performance and used to cover the firm's own operating costs (salaries, offices, deal expenses); and carried interest — commonly 20% of the fund's profits above a minimum return threshold, paid to the GP only once the fund actually returns capital to LPs. [Established] Andrew Metrick and Ayako Yasuda's academic paper "The Economics of Private Equity Funds" (Rodney White Center Working Paper 17-07, Wharton) formalizes this and documents real dispersion around the 2%/20% norm across a large dataset of actual fund terms — treat "2 and 20" as an anchor figure, not a universal rule. [Directional] for the specific dispersion around that anchor.

#The hurdle-rate waterfall

Most funds don't pay carry on every dollar of profit from the first dollar onward — they use a hurdle rate (commonly 8%): LPs must receive their capital back plus an 8% annualized return before the GP earns any carry at all. Metrick and Yasuda's paper walks through a worked example: on a $100M fund with a 20% carry level, an 8% hurdle, and a 100% catch-up provision, once exit proceeds clear the amount needed to give LPs their capital plus the 8% hurdle, a "catch-up" mechanism then directs profit disproportionately to the GP until the GP has caught up to its intended 20% share of total profits from that point forward — after which further profit splits 80/20 as normal. [Established] — this is the paper's own formalized illustration of the mechanism, not a secondary summary of it.

The practical effect for a candidate evaluating a PE offer: carry is not a guaranteed bonus, and it is not paid annually the way a bank bonus is — it depends on the fund's realized performance at exit, years after the investment was made, and depends on clearing the hurdle first. [Directional]

#Carry is a junior-level mirage, not a junior-level paycheck

At the associate level, meaningful carry is rare: where associates receive any carry allocation at all, it's commonly reported in the 0.1%–0.5% range of the fund's total carry pool, vesting over the fund's multi-year life (often with a vesting schedule similar to standard 4–5-year equity vesting with a 1-year cliff, layered on top of the fund's own 7–12-year timeline to full carry realization) — meaningful carry income typically starts materializing at the vice-president level and above. [Directional] Base-plus-bonus cash compensation, not carry, is the realistic driver of an associate's actual take-home pay in the first several years — reported in the sources surveyed for this course at roughly $150,000–$200,000 base for a first-year associate, climbing toward $165,000–$180,000 at megafunds specifically, with total first-year cash compensation (base plus bonus) commonly cited in the $300,000–$425,000 range at megafunds and somewhat lower at middle-market funds. [Directional] — figures vary meaningfully by firm size and fund performance and none of this research traced a specific number to a fund's own disclosure; treat these as a directional planning range, not a guarantee.

#Kaplan and Schoar: what the fee structure has actually produced

Steven Kaplan and Antoinette Schoar's foundational study, "Private Equity Performance: Returns, Persistence, and Capital Flows" (published in The Journal of Finance, 2005, building on an earlier NBER working paper), analyzed a large sample of PE and VC funds and found two results that matter for understanding the industry as a business, not just as an investment product: average fund returns net of fees have historically been roughly comparable to the S&P 500 over the sample period studied — with substantial dispersion between individual funds — and fund performance persists strongly across a given partnership's successive funds, meaning a GP's past fund performance is a real predictor of its next fund's performance in a way stock-picking skill generally isn't for individual public-market managers. [Established] — a peer-reviewed, widely cited academic finding, though it reflects the specific historical sample period the paper studied rather than a permanent constant; more recent PE-return data (available from data vendors like Preqin and PitchBook) should be checked directly for a current-period view rather than assumed unchanged from a 2005 paper's sample. [Directional] for how well that specific historical finding generalizes to any given recent vintage.

#Why this fee structure pushes PE toward different decisions than a hedge fund makes

A hedge fund often charges the same "2 and 20" language, but the mechanism behind it works very differently, because of one structural fact: hedge-fund capital is typically redeemable — LPs can often pull money out quarterly or annually — where PE capital is locked up for the fund's roughly ten-year life. [Established] That single difference changes what each business is built to optimize for: a hedge fund's GP has to defend assets under management against redemption every quarter, which pushes toward strategies that can show consistent, low-volatility, relatively liquid performance on a short reporting cycle. A PE GP faces no equivalent quarterly redemption pressure — its LPs are locked in regardless of a quarter's mark-to-market performance — which frees a PE firm to pursue strategies whose payoff only shows up years later: buying a company, spending several years actually changing how it operates, and only then selling it. [Established] for the redeemability difference itself; [Directional] for how much that specific mechanism, versus other factors, explains the resulting strategic difference between the two business types.

The use of significant leverage in PE deals has a related, separately documented rationale beyond simply amplifying equity returns: Michael Jensen's 1989 Harvard Business Review paper "Eclipse of the Public Corporation" argued that debt imposes real operating discipline on a company's management — a fixed obligation to make interest and principal payments constrains management from wasting free cash flow on empire-building or low-return projects in a way that diffuse public shareholders, without that same contractual leverage, historically struggled to enforce. [Established] as a peer-reviewed academic argument that shaped how the industry itself talks about the rationale for leverage; [Directional] for how fully it explains PE returns specifically, since Jensen's argument is one contested strand of a broader academic literature on LBO value creation, not a settled consensus figure.

Put together: the ten-year lock-up removes the pressure toward short-term performance that shapes a hedge fund, and the debt used in a typical deal both amplifies equity returns mechanically and, on Jensen's argument, imposes real operating discipline on the acquired company — which is why a PE firm's day-to-day work looks like operating and improving specific companies over a period of years, not trading in and out of positions on a market's daily moves.

The next two modules turn to venture capital, where the same "2 and 20" language produces a business that looks almost nothing like this one.
