Private equity refers to investment capital deployed into companies that are not publicly traded on a stock exchange.
Private equity firms raise money from institutional investors and wealthy individuals, pool it into a fund, and use that capital to acquire, grow, or restructure companies — typically over a period of several years — before selling the investment for a profit.
For most retail investors, direct access to private equity remains limited by regulatory requirements, but understanding how PE works is relevant to anyone tracking their retirement portfolio, evaluating employer equity compensation, or considering whether to pursue accredited investor status.
This guide covers the main private equity strategies, how funds are structured, how returns are generated, and the regulatory framework overseen by the SEC. Investors evaluating private equity against more accessible alternatives like mutual funds should weigh liquidity, fees, and time horizons carefully.
What Private Equity Is
Private equity (PE) is a category of alternative investment that involves ownership stakes in companies that are not listed on public stock exchanges like the NYSE or Nasdaq.
Unlike buying shares of Apple or Microsoft through a brokerage account, investing in private equity means committing capital to a fund that has discretion over which private companies to buy, how to operate or improve them, and when to sell.
The term "private equity" is broad.
It encompasses everything from venture capital backing a pre-revenue startup to a leveraged buyout of an established Fortune 500 division.
What these strategies share is the private nature of the investment, a long time horizon (often seven to ten years), and limited liquidity — meaning investors generally cannot sell their stake on demand the way they can sell public stocks.
According to Investor.gov, the SEC's investor education resource, private equity funds are typically structured as limited partnerships and are subject to the Investment Advisers Act of 1940 when they meet certain size thresholds.
How Private Equity Funds Work
The standard private equity fund structure separates two groups of participants:
- Limited Partners (LPs) — the investors who provide the capital. LPs typically include pension funds, university endowments, insurance companies, sovereign wealth funds, and high-net-worth individuals. They commit capital but are not involved in day-to-day investment decisions.
- General Partner (GP) — the private equity firm itself. The GP manages the fund, sources and evaluates deals, sits on boards of portfolio companies, and ultimately decides when to sell investments.
A typical fund has a life of approximately 10 years, broken into two phases: a 5-year investment period during which the GP deploys committed capital, and a 5-year harvest period during which investments are exited and proceeds are returned to LPs.
The "2 and 20" Fee Structure
Private equity funds traditionally charge a 2% annual management fee on committed capital (used to pay staff, operations, and deal expenses) plus 20% carried interest — meaning the GP takes 20% of profits above a pre-agreed hurdle rate (typically 8%).
The remaining 80% of profits above the hurdle flows to LPs.
This "2 and 20" structure aligns the GP's incentives with strong returns, but it also means a substantial portion of gains goes to the fund manager before LPs see full profit participation.
Fund Lifecycle and Capital Calls
LPs typically do not transfer all committed capital upfront. Instead, the GP issues "capital calls" as investments are made during the investment period. An LP who commits $10 million to a fund might contribute that amount across five or six capital calls over several years.
This staged structure means LPs must maintain liquid reserves to meet calls on relatively short notice — typically 10 business days.
Main Private Equity Strategies
Not all private equity looks the same. The four primary strategies differ significantly in risk profile, typical returns, holding periods, and the stage of company they target.
Leveraged Buyouts (LBO)
The most recognized PE strategy. In an LBO, a PE firm acquires a company — often a mature, cash-flow-positive business — using a combination of equity from the fund and a significant amount of borrowed money (debt). The debt is typically placed on the acquired company's balance sheet.
The firm then works to improve operations, reduce costs, grow revenue, or pursue add-on acquisitions over 3–7 years before selling the company through an IPO, a strategic sale, or a sale to another PE firm.
Returns are amplified by leverage, but so is risk if cash flows weaken or interest rates rise.
Venture Capital (VC)
Venture capital funds invest in early-stage or startup companies, typically in exchange for equity.
VC investments carry the highest risk of any PE strategy — most individual investments may fail entirely — but a single outsized winner can drive returns for an entire fund.
VC is the mechanism behind many well-known technology and biotech companies.
The holding period before a liquidity event (IPO or acquisition) is often 7–12 years.
Growth Equity
Growth equity sits between VC and buyouts.
These investments target companies that are already profitable and growing, but need capital to accelerate expansion — entering new markets, acquiring competitors, or scaling operations.
Growth equity deals typically involve minority stakes (the founders retain control), less leverage than LBOs, and a medium-term horizon of 3–7 years.
Distressed and Turnaround Investing
Some PE firms specialize in acquiring companies that are financially troubled — in bankruptcy proceedings or facing severe operational challenges — at a discount, then restructuring them.
This strategy requires deep operational and legal expertise and a tolerance for significant uncertainty.
Returns, if the turnaround succeeds, may be substantial.
If it does not, capital may be fully lost.
Who Can Invest in Private Equity
Direct investment in private equity funds is restricted primarily to accredited investors under SEC rules.
As described in the SEC's Investor Bulletin on Accredited Investors, an individual generally qualifies as an accredited investor by meeting one of the following thresholds (as of current SEC rules):
- Net worth exceeding $1,000,000, excluding the value of your primary residence, individually or jointly with a spouse or spousal equivalent
- Income exceeding $200,000 individually (or $300,000 combined with a spouse or spousal equivalent) in each of the two most recent years, with a reasonable expectation of the same for the current year
- Certain professional credentials, including Series 7, 65, or 82 licenses in good standing
- Knowledgeable employees of the fund itself
For investors who do not meet these thresholds, some indirect PE exposure may be available through:
- Publicly traded PE firms (e.g., firms that have themselves gone public) — these shares can be purchased in a standard brokerage account but represent ownership in the management company, not the underlying funds
- Business Development Companies (BDCs) — publicly registered investment companies that lend to or invest in private companies; they trade on exchanges and have lower minimums
- Target-date retirement funds — some pension-style funds are beginning to include small PE allocations
Regulatory Oversight and Key Risks
Private equity advisers are regulated under the Investment Advisers Act of 1940.
Larger PE firms (those managing over $150 million) must register with the SEC as investment advisers and comply with disclosure, recordkeeping, and compliance obligations.
Smaller firms may qualify as exempt reporting advisers.
The SEC's private equity fund resource page provides guidance on the regulatory framework applicable to these firms.
Key risks for investors considering private equity include:
- Illiquidity — capital is typically locked up for 7–10 years with limited or no ability to exit early. By comparison, mutual funds and high-yield savings accounts offer far greater liquidity.
- High minimums — institutional PE funds often require minimum commitments of $1 million or more; some platforms targeting individual accredited investors may have lower minimums but still require $50,000–$250,000
- Leverage risk — LBO strategies amplify both gains and losses; rising interest rates may pressure portfolio companies carrying significant debt
- Valuation opacity — private companies are not marked to market daily; reported valuations may lag actual market conditions
- Manager selection risk — returns across PE funds vary enormously; top-quartile funds may significantly outperform public markets, while bottom-quartile funds may destroy capital
- Fee drag — the 2-and-20 structure means investors must generate returns well above 8% before outperforming a low-cost index fund on a net basis
Frequently Asked Questions
What is the difference between private equity and venture capital?
Venture capital is a subset of private equity that focuses specifically on early-stage and startup companies.
Traditional private equity (particularly leveraged buyouts) targets more mature, established businesses.
VC investments tend to be smaller and higher-risk, with the expectation that most investments may lose money but a few will generate outsized returns.
LBO-focused PE seeks steadier improvements to established businesses using financial engineering and operational changes.
Do I need to be an accredited investor to invest in private equity?
For direct investment in most private equity funds, yes — SEC rules generally limit participation to accredited investors who meet net worth or income thresholds.
However, indirect exposure through publicly traded PE firms or Business Development Companies (BDCs) is available to any investor with a standard brokerage account.
The SEC's accredited investor standards exist to help ensure that participants in high-risk, illiquid investments have the financial resources to absorb potential losses.
What does "carried interest" mean in private equity?
Carried interest — often called "carry" — is the share of investment profits that the general partner (the PE firm) receives above a specified hurdle rate, typically 8%.
Under the standard "2 and 20" model, the GP takes 20% of gains above the hurdle rate, and the remaining 80% goes to the limited partners.
Carried interest is the primary incentive mechanism for PE fund managers.
It is currently taxed at long-term capital gains rates in the U.S. rather than as ordinary income, which has made it a topic of ongoing tax policy debate.
How do private equity returns compare to the stock market?
Measuring PE returns relative to public markets is methodologically complex because PE funds report internal rate of return (IRR) rather than time-weighted returns, and valuations lag.
Top-quartile PE funds have historically outperformed public equity benchmarks over long periods, but average and below-average PE funds have often underperformed after fees.
The illiquidity premium — extra return required to compensate for locking up capital — is a key concept.
No historical performance guarantees future results, and manager selection is critical. For most retail investors, a diversified portfolio of low-cost mutual funds may provide better risk-adjusted returns than PE after accounting for fees and liquidity constraints.
Can a regular retirement account (IRA or 401k) invest in private equity?
Traditional employer 401(k) plans rarely include direct private equity options, though some large plans have begun offering small PE allocations through collective investment trusts.
Self-directed IRA accounts can, in theory, hold alternative investments including PE interests, but doing so requires a custodian that specializes in alternative assets and carries significant complexity and compliance considerations.
Anyone considering this approach should consult both a tax advisor and a fiduciary financial planner before proceeding.
