Private equity often gets talked about as a monolith: buyouts, big names, and billion-dollar exits. But ask ten professionals how do private equity funds work, and you’ll hear different answers—some will focus on the LP–GP relationship, others on deal execution, and still others on performance fees. The truth is that a PE fund is both a financing structure and a strategic operating model. It raises outside money, pools it into a blind pool or semi-blind pool of capital, and then deploys that capital into private businesses with the goal of generating outsized returns. But those mechanics are far from simple.

Why does it matter to understand them? Because the fund model dictates incentives, governance, and return profiles. For LPs, knowing how a fund really works helps them negotiate terms and evaluate managers. For GPs, structuring correctly determines whether they can raise again. And for operators, understanding fund incentives explains why portfolio companies are managed the way they are. This isn’t just financial plumbing—it’s the architecture of an entire asset class that now commands more than $8 trillion in assets under management globally, according to Preqin.

Let’s break it down step by step—starting with structure, then moving into strategy.

How Do Private Equity Funds Work? Structures Behind Capital Raising and Deployment

At the heart of every PE fund is the limited partnership model. Investors—called limited partners (LPs)—commit capital to the fund. These LPs can be pensions, endowments, sovereign wealth funds, family offices, or high-net-worth individuals. The general partner (GP) manages the fund: sourcing deals, structuring investments, and creating value post-acquisition.

The commitments made by LPs are not delivered up front. Instead, capital is drawn down through capital calls as investments are identified. This staged approach allows funds to pace deployment across market cycles and avoid sitting on idle cash. In practice, a $1 billion fund might call capital in tranches of 10–20 percent over its first three to four years.

Funds usually follow a 10-year lifecycle, although extensions are common. The early years are about capital deployment—buyouts, growth equity stakes, or structured deals. The middle years focus on operational value creation and add-on acquisitions. The later years emphasize harvesting—exits through IPOs, secondary sales, or sales to strategic buyers.

A key feature of the structure is the blind pool element. LPs commit before knowing the exact companies the fund will invest in. That’s why trust in the GP’s track record and strategy is so central. Some funds mitigate this with co-investment rights, allowing LPs to participate directly in select deals with reduced or no fees.

The fee structure deserves attention because it heavily influences incentives. The industry standard has long been “2 and 20”: a 2 percent management fee on committed capital and 20 percent carried interest on profits. For a $1 billion fund, that means $20 million per year in fees before performance. Many funds, especially in the mega-fund category, now negotiate fees closer to 1.5 percent or even 1 percent as scale grows, but carry remains a powerful motivator.

Debt financing also plays into how PE funds work. The GP doesn’t just deploy LP equity; it layers in leverage to amplify returns. That leverage sits at the portfolio company level, not the fund level, which insulates LPs from fund-wide debt obligations. Still, the fund’s overall risk profile is shaped by how aggressively managers use debt across their portfolio.

Finally, governance rights tie it all together. PE funds typically secure board seats, consent rights on major decisions, and control over liquidity events. Unlike public investors, they don’t just own shares—they own influence over how the business is run, aligned with a timeline that fits the fund’s lifecycle.

In short, the structure of a private equity fund is designed to align long-term investor commitments with concentrated ownership and high-impact operational control. It’s a system that magnifies both upside and risk, depending on execution.

Private Equity Fund Strategies: Buyouts, Growth Equity, and Beyond

If structure explains how the capital flows, strategy explains where it goes. The most common strategy is the leveraged buyout (LBO), where a fund acquires majority control of a business using a mix of equity and debt. But the universe of PE strategies is broader and constantly evolving.

Buyouts dominate the large-cap end of the market. Firms like KKR, Blackstone, and Carlyle acquire established businesses with steady cash flows. The goal is to improve operations, cut inefficiencies, and grow enterprise value before selling at a higher multiple. These deals often involve heavy leverage, but they also demand operational sophistication.

Growth equity takes a lighter touch. Firms like General Atlantic or Summit Partners invest in companies that are scaling quickly but don’t want to sell control. Growth equity deals provide expansion capital without the cultural shock of a buyout. Here, investors focus on go-to-market acceleration, new product lines, or geographic expansion. The risk is lower than venture but higher than buyouts—returns depend on both growth velocity and exit timing.

Sector-focused funds sharpen the strategy further. Thoma Bravo focuses on software, while GTCR leans into healthcare and financial services. By specializing, these funds claim an edge in diligence, sourcing, and operational value creation. The trade-off is concentration risk, but LPs often accept it in exchange for differentiated expertise.

Distressed and special situations strategies use capital to rescue or restructure companies under financial strain. Apollo, for example, has built a reputation in this space. Returns come from buying assets cheaply, restructuring debt, and steering turnarounds. The risk is high, but so is the potential upside.

Infrastructure and long-hold funds represent another corner of the PE landscape. Macquarie and Brookfield raise capital with longer fund lives—15 years or more—to match the durability of assets like toll roads, utilities, or data centers. This appeals to LPs seeking yield with lower volatility, though returns tend to be steadier rather than spectacular.

One overlooked dynamic is how strategy dictates portfolio construction. A buyout fund might aim for 10–15 concentrated investments. A growth equity fund may spread bets across 20–30 companies. A distressed fund could take even fewer positions, given the complexity of workouts. Each approach changes the liquidity profile, risk spread, and return potential of the fund.

For investors, the lesson is clear: asking how do private equity funds work means asking which strategy defines the fund. Because in PE, structure without strategy is just scaffolding—the value comes from how managers put it to work.

Investor Returns in Private Equity: From Fees to Performance Metrics

For all the complexity around fund structures and strategies, the ultimate question for LPs is simple: what do the returns look like, and how do they flow back? To answer that, you need to unpack how private equity calculates, reports, and distributes performance.

The fee model comes first. As noted earlier, most PE funds charge a management fee (often 1–2 percent of committed capital) plus carried interest (usually 20 percent of profits). But the way these are layered matters. Some funds charge fees on committed capital during the investment period, then switch to charging on invested capital afterward. That shift can significantly reduce the drag on returns over a 10-year cycle.

Carried interest is usually triggered only after investors receive back their contributed capital plus a preferred return—commonly 8 percent. This “hurdle rate” ensures that GPs earn carry only when LPs achieve a minimum benchmark return. Above that, profits are split, often 80/20, though some funds negotiate tiered carry structures with higher percentages once certain IRR thresholds are met.

The performance metrics used to evaluate PE returns are different from those in public equities. Three dominate:

• IRR (Internal Rate of Return): Measures the annualized return, factoring in the timing of cash flows. IRR is sensitive to early exits, which can make a fund look better than it is if distributions come quickly.
• MOIC (Multiple on Invested Capital): Simpler but powerful. It shows how many times over the fund has returned investors’ money (e.g., 2.5x MOIC means $100 million in becomes $250 million out).
• DPI (Distributions to Paid-In Capital): Tracks actual cash returned relative to what was invested. Unlike IRR, DPI can’t be inflated by paper gains—it’s cash-on-cash reality.

Sophisticated LPs also examine TVPI (Total Value to Paid-In Capital), which combines realized and unrealized returns. The gap between DPI and TVPI tells you how much of a fund’s performance is still on paper. In an environment where exits are slowing, that distinction is critical.

What’s often overlooked is how capital pacing impacts returns. A $1 billion fund that calls 40 percent of its capital quickly and returns it within four years can show a stellar IRR. But a similar MOIC stretched over 10 years will look mediocre in IRR terms. That’s why LPs ask not only what returns are, but when they come.

Real-world examples make this concrete. Blackstone’s Flagship Fund V (vintage 2006) delivered a net IRR of around 12 percent and a MOIC of 1.6x. Respectable, but not spectacular. By contrast, Thoma Bravo’s Fund XII (vintage 2016) generated over 30 percent net IRR by 2022, fueled by software buyouts with rapid value realization. The difference wasn’t just strategy—it was pacing, exit timing, and sector tailwinds.

For LPs, the takeaway is simple: private equity returns are not measured only by the top line. They’re shaped by structure, timing, and the fund’s discipline in aligning fees and distributions with investor outcomes. Asking “how do private equity funds work” is inseparable from asking how they create and share value with those who supply the capital.

Risks, Resilience, and the Future of Private Equity Fund Models

Private equity’s growth has been remarkable, but the fund model faces increasing scrutiny. Rising rates, tougher regulations, and changing LP preferences are testing whether the traditional playbook is sustainable. To understand the risks, you need to see where funds stumble—and how they adapt.

Leverage risk remains central. In the last decade, sponsors pushed debt multiples higher, particularly in software deals where predictable revenues justified 8x or 9x EBITDA. But with interest rates rising, servicing that debt has become more expensive, compressing free cash flow. Funds must now demonstrate operational value creation rather than relying on cheap capital.

Liquidity risk has also come into focus. Traditional PE funds lock capital for 10–12 years, but many LPs want more flexible exposure. This has fueled the boom in secondaries and continuation vehicles, where fund stakes are sold or extended. StepStone, Lexington, and Coller Capital have built multi-billion-dollar franchises around solving LP liquidity problems. These innovations don’t replace the traditional model, but they reshape it.

Fee pressure is another challenge. LPs are increasingly unwilling to accept full “2 and 20” economics for mega-funds. Co-investments and SMAs (separately managed accounts) give investors direct access with reduced fees. Sovereigns and large pensions, like Canada’s CPPIB or Singapore’s GIC, often bypass funds altogether by building direct-investing teams. For FoF managers and second-tier GPs, that trend is existential.

On the resilience side, the PE model has proved adaptable. After the financial crisis, funds leaned into operational playbooks, building out portfolio support teams to drive EBITDA growth. Today, that focus has intensified: firms hire former CEOs, tech specialists, and supply chain experts to sit alongside deal teams. Value creation is no longer just leverage—it’s executional expertise.

The future of the model may lie in hybrid structures. Evergreen funds, open-ended vehicles, and NAV-based financing all push against the 10-year blind-pool norm. Blackstone, Apollo, and KKR have already raised tens of billions in perpetual capital vehicles that promise investors yield and liquidity rather than just long-term illiquidity premiums. For LPs, these products blur the line between private equity and private credit, but they offer flexibility in exchange for lower return targets.

Geopolitics will also shape how PE funds work going forward. U.S.–China tensions are forcing firms to reconsider cross-border strategies. European regulators are pressing harder on ESG disclosures. Emerging markets are offering growth, but also higher political risk. In this environment, the most resilient funds are those that treat structure as a tool, not a given.

Ultimately, the question “how do private equity funds work” cannot be answered once and for all. It evolves. The mechanics—LP commitments, GP deployment, leverage, exits—remain, but the strategies and adaptations change with each cycle. The constant is alignment: between fund structures, investment strategies, and the returns investors expect.

Private equity funds are not just pools of capital. They are carefully designed structures where commitments, incentives, and strategies intersect to create—or destroy—value. At their core, they work by raising long-term capital from LPs, deploying it into companies through tailored strategies, and harvesting gains within a defined horizon. Along the way, returns are shaped by fees, pacing, leverage, and execution discipline. The risks are real—overleverage, misaligned incentives, or liquidity traps can erode value quickly. Yet the model has proved remarkably durable because it adapts: from blind-pool buyouts to sector specialists, from long-hold infrastructure to perpetual capital vehicles. For investors and operators alike, understanding how private equity funds work is less about memorizing mechanics and more about reading incentives, strategies, and cycles. The better you understand the model, the sharper your judgment in allocating, raising, or partnering within it.
