What Is Private Equity? How PE Funds Actually Work

Private equity is investment in companies that are not publicly traded. "PE" usually refers to a specific version of that: pooled funds that acquire controlling stakes in established businesses, improve them over several years, and sell them. The defining features are control, leverage, illiquidity, and a fixed time horizon.

What separates it from public investing

• Control, not a position. A PE firm typically buys enough of a company to appoint the board and direct strategy, rather than holding a minority stake and hoping management performs.

• No daily price. Value is marked periodically against comparable companies and transactions, so reported returns are estimates until an exit produces cash.

• Locked capital. Investors commit for the life of the fund, commonly ten years with extensions. There is no redemption window.

• Leverage. Acquisitions are financed partly with debt placed on the target company — the leveraged buyout — which amplifies both returns and risk.

Private equity versus venture capital

Both invest in private companies, and the terms are often used loosely, but the strategies differ:

• Buyout PE acquires mature, cash-generating businesses using debt, takes control, and underwrites to a base case. Most deals are expected to work.

• Venture capital buys minority stakes in unprofitable early-stage companies with equity only, and underwrites to a power law where a small number of investments carry the fund.

• Growth equity sits between them: significant minority investments in businesses that already have revenue and product-market fit.

How a fund is structured

A PE fund is almost always a limited partnership or LLC with two sides:

• The general partner — the firm. It sources deals, makes investment decisions, manages portfolio companies, and is liable for the fund's obligations.

• The limited partners — pensions, endowments, insurers, family offices, funds of funds, and increasingly individuals. They provide the capital and have no role in management.

LPs sign subscription documents committing capital rather than wiring it upfront. The GP then issues capital calls as deals require funding, and returns cash through distributions as investments exit. Because the entity is a pass-through, income and gain are reported to LPs on a Schedule K-1 rather than a 1099.

How managers get paid

The traditional model is "2 and 20":

• A management fee of roughly 2% of committed capital annually, funding the firm's operations.

• Carried interest of about 20% of profits, usually payable only after LPs receive a preferred return — the hurdle, often 8% — and after their capital is returned.

Both numbers are negotiated in practice, and the distribution waterfall in the partnership agreement is what actually governs the split. Emerging managers and single-deal vehicles frequently run carry with no management fee at all.

The fund lifecycle and the J-curve

1. Fundraising — securing commitments, typically over 12 to 24 months.

2. Investment period — roughly years one through five, deploying capital into new deals.

3. Value creation — operational improvements, add-on acquisitions, debt paydown.

4. Harvest — exits via strategic sale, sponsor-to-sponsor sale, IPO, or recapitalization.

Early on, fees and expenses are drawn while investments are still held at cost, so reported returns are negative. As exits arrive, the line crosses back over. Plotted over time this is the J-curve, and it is why judging a fund in year two is meaningless.

How returns are measured

• IRR — annualized return accounting for timing of cash flows. Sensitive to early distributions and to subscription-line financing, so it can be flattered.

• MOIC — multiple on invested capital, ignoring time.

• TVPI — total value to paid-in: distributions plus remaining value, over capital called.

• DPI — distributions to paid-in. Cash actually returned. The number that cannot be marked.

Read DPI first. TVPI depends on the manager's own marks; DPI does not.

How individuals get access

Direct fund commitments have historically required accredited or qualified purchaser status and minimums in the millions. Four routes have opened up:

• SPVs. A single-deal vehicle pools smaller checks into one position, letting a sponsor bring investors into a specific company or fund at a much lower minimum. This is now the most common entry point for individuals into private markets.

• Secondaries. Buying existing LP interests or employee shares, often at a discount, with a shorter remaining hold.

• Evergreen and interval funds. Semi-liquid registered structures with lower minimums and periodic redemption windows.

• Retirement channels. Private capital entering defined contribution plans through target-date and managed-account wrappers — covered in our piece on private equity in 401(k)s.

Each adds a layer of fees and its own tax reporting, which is worth modeling before committing.

If you are running the vehicle

The operational load is the part first-time managers underestimate: entity formation, subscription documents and accreditation checks, banking, capital calls, tax-basis capital accounts, valuations, LP reporting, distributions, and K-1s — every year, whether or not anything happened. Allocations provides entity creation, fund administration, and distributions for SPVs and funds on flat-fee pricing, which is what makes smaller vehicles economically viable in the first place.

Frequently asked questions

What is private equity? Investment in privately held companies, usually through pooled funds that take controlling stakes, improve the businesses over several years, and sell them.

What does PE stand for? Private equity. In finance it can also mean price-to-earnings ratio, so context matters.

How is private equity different from venture capital? PE buys control of mature, cash-generating companies using leverage. VC buys minority stakes in early-stage companies with equity only and accepts that most investments will fail.

How do private equity firms make money? Management fees on committed capital, typically around 2%, and carried interest on profits, typically around 20% above a preferred return.

How long is capital locked up? Commonly ten years with possible extensions, though secondaries and evergreen structures offer earlier liquidity.

Can individual investors invest in private equity? Yes — most commonly through SPVs, secondaries, evergreen or interval funds, and increasingly through retirement plan wrappers. Eligibility rules and minimums vary by route.

What is the J-curve? The pattern of negative early returns caused by fees and expenses preceding exits, followed by positive returns as investments are realized.
