The real difference between gross IRR and net IRR comes down to one simple thing: fees. Gross IRR shows you how a fund’s investments performed on their own, before any fees or profit-sharing are taken out. Net IRR is what’s left for the investor—the actual return that hits their account after all the management fees, fund expenses, and carried interest are paid.
It’s helpful to think of it this way: gross IRR is the fund manager’s report card, while net IRR is your personal take-home pay.
Understanding the Core Difference in IRR
At its heart, the distinction separates a General Partner's (GP) investment skill from a Limited Partner's (LP) actual financial outcome. Gross IRR zooms in on the performance of the underlying assets, telling you how good a GP is at finding, growing, and selling companies. It answers the question, "How skilled is this manager at picking winners and creating value?"
On the other hand, Net IRR is the bottom-line figure for LPs. It’s the metric that truly matters because it accounts for the entire economic structure of the fund. This is the number that shows the real-world impact of all costs and ultimately determines the true return on an LP's committed capital. The gap between these two figures is often called the "gross-to-net spread," and it tells you exactly how much it cost to participate in the fund.
Gross IRR vs Net IRR Key Distinctions at a Glance
For a quick reference, the table below breaks down the fundamental differences between these two crucial metrics.
This quick comparison highlights how each metric serves a different audience and purpose in the world of private equity and venture capital.
Don't underestimate how much the spread between these two numbers can matter. A detailed Cambridge Associates report on North American buyout funds showed an average gross IRR of 18.5% per year. After fees and expenses, that translated to a net IRR of just 14.2% for investors. That’s a 4.3 percentage point difference every single year.
Ultimately, you need both metrics to get the full picture. A high gross IRR signals a skilled manager, but if their fee structure is too high, the net IRR you receive could be underwhelming. Properly tracking these key performance indicators is a critical first step in successful portfolio monitoring.

How Gross IRR Reveals a GP's Skill
General Partners (GPs) lean heavily on Gross Internal Rate of Return (IRR) for a simple, yet powerful, reason: it isolates their ability to pick winners and create value. Think of it as the purest measure of investment performance, focusing only on the cash flowing between the fund and its portfolio companies.
For Limited Partners (LPs) doing their due diligence, this metric cuts right to the chase. It answers the most critical question: "How good is this manager at finding great deals, growing them, and making a profitable exit?" By stripping out management fees, carried interest, and other fund-level expenses, Gross IRR provides an unfiltered look at a GP's strategic and operational talent.
A Step-by-Step Gross IRR Example
Let's walk through a practical example to see how this works. We'll follow a single investment made by "VC Fund Alpha" into a startup called "InnovateTech." The calculation only cares about the money moving directly in and out of the investment itself.
Here’s the timeline:
January 1, 2021 (Year 0): VC Fund Alpha invests $5 million into InnovateTech. This is our first cash outflow.
July 1, 2022 (Year 1.5): InnovateTech needs more runway to scale. VC Fund Alpha makes a follow-on investment of another $2 million. This is our second cash outflow.
January 1, 2026 (Year 5): A major competitor acquires InnovateTech. VC Fund Alpha sells its entire stake, receiving $25 million in proceeds—our one and only cash inflow.
These are the only three cash flows that matter for the Gross IRR. You'll notice we haven't mentioned the fund's 2% management fee or the 20% carried interest the GP earns. That's intentional.
Key Takeaway: The Gross IRR calculation is deliberately sterile. It focuses exclusively on capital deployed into an asset and the proceeds received from it, giving you a direct measure of investment performance.
Calculating the Gross IRR
To get the Gross IRR, we need to find the annualized discount rate that makes the net present value (NPV) of all these cash flows equal zero. While you'd almost always use software or a spreadsheet function like XIRR to do this instantly, the goal is to solve for 'r' in the NPV formula based on our specific dates and amounts.
Here’s the data we’d plug in:
Plugging these numbers into a calculator gives us a Gross IRR of 34.6%. That's a powerful figure. It tells a clear story about the GP's ability to turn $7 million of invested capital into $25 million over five years.
Why This Metric Matters for GPs
For any GP, a strong Gross IRR is a cornerstone of their marketing and fundraising efforts. It lets them prove their core competency without getting bogged down in the fund's specific economics. It’s their way of saying, "Look at the raw returns we can generate at the asset level. We know how to pick and grow businesses."
This becomes especially critical when comparing managers. Two funds might have wildly different fee structures, which could dramatically impact their Net IRRs. But comparing their Gross IRRs offers a much cleaner, apples-to-apples look at their investment skill. It’s the purest reflection of their ability to generate alpha before any fees get in the way. At its core, the difference between gross IRR vs net IRR is a story of raw skill versus the final outcome.
Calculating Net IRR: What You Actually Take Home
If Gross IRR shows a GP's knack for picking winners, Net IRR is the number that really hits home for you, the Limited Partner (LP). This is your actual, bottom-line return after all fund expenses, fees, and the GP's share are taken out. It answers the most important question: "After everyone got paid, what was my real annualized return?"
To get to the Net IRR, we have to look at the cash flows from the LP's perspective. That means factoring in every cost of being in the fund, which naturally reduces the cash distributed back to you. The big two are management fees and carried interest, but other fund-level expenses play a role too.
Adjusting Cash Flows for Fees and Carry
Let's go back to our "VC Fund Alpha" and its investment in "InnovateTech," which posted that impressive 34.6% Gross IRR. Now, we’ll see what that looks like for an LP who committed $10 million to this $100 million fund, giving them a 10% stake.
We'll assume the fund uses a standard "2 and 20" model:
Management Fee: 2% annually on committed capital. For our LP, that’s $200,000 every year.
Carried Interest: 20% of the profits are paid to the GP, usually after LPs get their initial investment back.
The gross cash flows were simple: two investments out, one big exit in. For the Net IRR calculation, the LP's cash flow reality is a bit more complicated. It includes capital calls for the investment and for management fees, followed by a smaller distribution once the GP takes their carry.
A Step-by-Step Net IRR Example
Here’s the updated cash flow timeline from our LP's point of view, assuming fees are called at the start of each year.
January 1, 2021 (Year 0): The LP contributes $500,000 for the InnovateTech deal (10% of $5M) and pays a $200,000 management fee. Total outflow: -$700,000.
January 1, 2022 (Year 1): The LP pays the annual $200,000 management fee. Total outflow: -$200,000.
July 1, 2022 (Year 1.5): The LP contributes $200,000 for the follow-on round (10% of $2M). Total outflow: -$200,000.
January 1, 2023 - 2025 (Years 2, 3, 4): The LP pays the $200,000 management fee each year. Total outflow over this period: -$600,000.
January 1, 2026 (Year 5): The LP receives their share of the exit proceeds.
So, how much do they actually get back? The total profit on the investment was $18 million ($25M exit - $7M cost). The GP’s 20% carried interest comes to $3.6 million. This leaves $14.4 million in profit for the LPs. Our LP’s 10% share of that profit is $1.44 million. They also get their original $700,000 of invested capital back. Total inflow: +$2,140,000.
Key Insight: Net IRR is calculated from the LP’s bank account. Every dollar paid to the fund (for investments or fees) is an outflow, and every dollar received from the fund is an inflow. This provides the true measure of investment performance.
When you plug these more detailed cash flows into a spreadsheet, you get a Net IRR of 21.9%.
The difference is stark:
Gross IRR: 34.6%
Net IRR: 21.9%
That 12.7 percentage point spread is the direct cost of participating in the fund. This gap between gross and net IRR isn't out of the ordinary. In fact, a well-known study on private equity performance found that the gap often gets wider for top-performing funds. You can read more about these private equity performance findings to see the industry trends.
While you can work these numbers out in a spreadsheet, the complexity makes it easy for errors to creep in. It’s why many firms are exploring the benefits of moving beyond reporting in Excel to ensure their most critical performance metric is always accurate. For any investor, this is the number that defines success.
What Drives the Gap Between Gross and Net IRR
The space between Gross and Net IRR isn’t just some random number; it’s a detailed story about a fund’s specific economic structure. For any LP digging into a Private Placement Memorandum (PPM), figuring out what creates this performance gap is essential to understanding the fund's financial engine. This gap, often called the gross-to-net spread, comes from several key factors that systematically chip away at the raw investment return before it ever reaches an investor's pocket.
The most obvious culprits are the fund’s fees and expenses. These are the direct costs of doing business, and they're the main reason a Net IRR will always be lower than a Gross IRR. But the story is more nuanced than just subtracting a few percentage points.
This visual flow shows exactly how gross returns are methodically reduced by fees to arrive at the net return that investors ultimately receive.
As the diagram makes clear, Net IRR is what’s left for an LP after the fund’s economic engine has taken its share.
Management Fees
Management fees are the most consistent and predictable factor widening the gap between gross and net. Typically structured as 1.5% to 2.5% of committed capital each year, these fees get charged whether the fund is knocking it out of the park or struggling. They cover the GP’s operational costs—think salaries, office space, and due diligence expenses.
Because these fees are drawn down regularly throughout the early life of a fund, often before any real gains are on the books, they create a constant drag on returns. This steady cash outflow has a direct, negative impact on the Net IRR calculation from day one and is a big contributor to the J-curve effect, where early fund returns are negative.
Carried Interest and Waterfall Mechanics
While management fees are a steady drain, carried interest (or "carry") is the performance-based fee that often creates the largest chunk of the gross-to-net spread, especially in successful funds. This is the GP's share of the profits, usually 20%, and its impact is dictated by the fund's waterfall structure.
The waterfall lays out the pecking order for how proceeds from exits get distributed. It’s a multi-step process:
Return of Capital: First, LPs must get all their contributed capital back.
Preferred Return (Hurdle Rate): Next, LPs earn a minimum annualized return (often 6-8%) on their investment before the GP can see a dime of carry.
GP Catch-Up: Once the hurdle is cleared, the GP often receives a higher portion of profits until they've "caught up" to their full 20% share of total profits.
Final Split: After the catch-up, remaining profits are split, usually 80/20, between LPs and the GP.
The hurdle rate can initially protect LP returns and keep the gap narrow. However, once a high-performing fund blows past its hurdle and the catch-up kicks in, the GP's share of profits accelerates, rapidly widening the spread between Gross and Net IRR.
Key Differentiator: The structure of the carried interest waterfall—specifically the hurdle rate and catch-up provisions—has a more dynamic and potentially larger impact on the gross-to-net spread than the flat management fee, especially in high-performing funds.
The data backs this up. According to a 2023 report from McKinsey & Company, the top 10% of global private equity funds posted an average gross IRR of 32.1%, but their net IRR was only 25.8%. That 6.3 percentage point difference shows just how much more pronounced the fee drag becomes for the best-performing funds, largely due to carried interest. You can find more details in the full analysis of internal rates of return.
The table below gives a clearer picture of how different fee structures can influence the final spread.
Impact of Fees and Carry on IRR Spread
As you can see, the spread widens dramatically as performance improves and carried interest kicks in, dwarfing the impact of the management fee alone.
The Role of Fund Expenses and Timing
Beyond the main fees, other fund-level expenses also contribute to the performance gap. We’re talking about legal fees, administrative costs, audit expenses, and insurance. While smaller than management fees or carry, they are still subtracted from gross returns and reduce the cash available for LPs.
Finally, the timing of cash flows plays a subtle but critical role. IRR is extremely sensitive to when cash is deployed and returned. Early management fee payments have a disproportionately negative effect on Net IRR. On the flip side, an early, successful exit can boost both Gross and Net IRR, but the subsequent carry distribution will still widen the gap. The fund's lifecycle stage is a major factor here; the spread is often widest during the early years (due to fees) and the later years (due to carry).
Why You Can't Just Pick One IRR
It's tempting to ask which is better: gross or net IRR. But that's the wrong question. One isn't superior to the other; they just tell different, equally important parts of the same story. For both General Partners (GPs) and Limited Partners (LPs), you need both to get the full picture of a fund's performance.
For a GP, Gross IRR is the purest measure of their investment chops. It isolates their core skill: finding great companies, helping them grow, and selling them for a profit. When a GP hits the road to raise their next fund, potential LPs will pore over the Gross IRR to see just how good they are at the fundamental job of investing. It’s the most direct way to compare raw deal-making talent across different managers, without the noise of varying fee structures. A high Gross IRR is proof that the GP knows how to create value.
For an LP, however, Net IRR is the only number that really hits home. It’s the bottom line. This is the actual, annualized return that lands in their pocket after all management fees, fund expenses, and carried interest are paid out. LPs rely on Net IRR to see how their capital is truly performing and to compare managers on an all-in basis. It answers the most critical question for any investor: "What did I actually make on this?"
The Different Conversations They Drive
A good way to think about this is that each metric fuels a different, necessary conversation between a GP and their LPs.
The GP Fundraising Conversation: When a GP is raising a new fund, the conversation is all about their ability to generate alpha. Gross IRR is the star of this show. It lets the GP showcase their investment track record without getting bogged down in the specific economics of a fund.
The LP Due Diligence Conversation: When an LP is deciding whether to invest, they're laser-focused on the Net IRR of the GP's prior funds. They need to know what returns were actually delivered to the people who came before them. A huge gap between a fund's Gross and Net IRR will definitely lead to some tough questions about fees and fund economics.
Key Insight: Gross IRR tells you how skilled the manager is. Net IRR tells you what the investor actually gets. A great fund partnership needs both to be strong. A stellar Gross IRR doesn't mean much to an LP if an expensive fee structure eats it all away.
Seeing the Complete Picture
If you only look at one of these metrics, you're flying with a blind spot. A GP who only talks about their high Gross IRR might be trying to distract from a fee structure that leaves little for investors. On the flip side, an LP who only looks at Net IRR might pass on a truly gifted manager whose fees are justified by top-tier performance.
In the end, the two metrics are a team. The Gross IRR shows you what a GP is capable of—their raw value-creation power. The gap between Gross and Net IRR, often called the "gross-to-net spread," tells you the cost of accessing that skill. By looking at both, LPs can make much smarter, more balanced decisions. They can find skilled managers whose fund structures actually align with their own financial goals.
Why You Should Stop Calculating IRR in Spreadsheets
Trying to manually calculate the difference between gross IRR and net IRR in a spreadsheet is a high-wire act. It’s a ton of work, and the stakes are incredibly high. The whole process is famously susceptible to human error—a simple typo, a broken formula, or inconsistent logic can throw everything off. As a portfolio gets bigger, this manual data wrangling quickly becomes a serious operational headache.
Relying on spreadsheets builds a house of cards. One wrong formula can completely misrepresent fund performance, leading to bad strategic calls and, even worse, a loss of investor trust. For both GPs and LPs, depending on error-prone manual work for metrics this critical is a risk you just don't need to take.

Common Questions About IRR
Even once you have the basics down, real-world situations can still make you pause and think about the difference between gross and net IRR. Let's dig into a few of the most frequent questions that come up for both LPs and GPs.
Can a Fund Have a Positive Gross IRR but a Negative Net IRR?
Absolutely. This isn't just possible; it's pretty common, especially in the early years of a fund's life. This happens when a fund’s initial investment returns haven’t grown enough to outpace the steady drain of management fees and fund expenses.
Imagine a fund generates a modest gross IRR of 4% on its first few deals. If that fund charges a 2% annual management fee on committed capital, those fees can easily eat up all the early gains. For the LP, this can push the net IRR into negative territory, even while the underlying investments are technically profitable. It's a perfect illustration of why LPs have to anchor their analysis on net IRR—it’s the only number that reflects what actually ends up in their pocket.
How Do GIPS Reporting Standards Affect IRR Calculations?
The Global Investment Performance Standards, or GIPS, are essentially the ethical rulebook for reporting performance in a consistent way. When a firm complies with GIPS, it makes life much easier for LPs trying to compare different managers.
A core tenet of the GIPS standards is the recommendation to present returns both gross-of-fees and net-of-fees. This dual approach gives investors the full picture: they can see the manager's raw stock-picking skill (Gross IRR) alongside the actual return they received after all costs were deducted (Net IRR).
Following these standards creates a level playing field. It gives LPs confidence that they're comparing apples to apples when looking at IRR figures from different funds.
Why Use IRR Instead of a Simpler Metric Like MOIC?
While MOIC (Multiple on Invested Capital) is a critical metric, it only gives you part of the picture. MOIC tells you the magnitude of your return—a 2x MOIC means you doubled your money, plain and simple. What it completely ignores, however, is the crucial element of time.
IRR, on the other hand, is all about the "when." It's a time-weighted metric that measures how quickly and efficiently you generated that return.
Getting a 2x MOIC in just two years? That’s a fantastic IRR.
Taking ten years to achieve that same 2x MOIC? That translates to a pretty mediocre IRR.
This is exactly why seasoned investors never look at one without the other. MOIC tells you how much money you made, while IRR tells you how fast you made it. Using them together provides a much more complete and insightful view of an investment's true performance.
