What it means
Internal rate of return is the annualised percentage growth rate that makes an investment's cash inflows and outflows balance out to zero today. Gross IRR applies that calculation at the deal or portfolio level, counting only the money that went into assets and the money those assets returned.
Fund managers use gross IRR because it isolates their investment skill. Fees are a function of how the fund was structured and how much capital was raised, so stripping them out lets a manager show what the buying, improving and selling decisions actually produced.
Investors care about the same number for a different reason. The gap between gross and net IRR is the cost of the fund wrapper, and comparing the two tells a limited partner exactly how much of the value created by the assets ended up in the manager's pocket rather than their own.
The size of that gap is usually several percentage points. A typical private equity structure charges an annual management fee of about 2% of committed capital plus 20% of profits above a hurdle, which commonly turns a gross IRR in the low twenties into a net IRR in the mid to high teens.
Gross IRR is also sensitive to timing in a way that trips people up. Because it is an annualised rate, returning capital quickly flatters the percentage even when the total profit is small, which is why serious investors always read gross IRR alongside a multiple of invested capital.
In practice
Real-world examples.
Example
A venture fund raising its third vehicle presents a gross IRR of 34% on its previous fund. A cautious pension investor asks for the net figure, receives 24%, and uses the ten point gap to negotiate the fee terms on the new fund rather than simply accepting the headline.
Example
A real estate manager reports gross IRR by individual property so its investment committee can see which asset managers are creating value. One office refurbishment shows a gross IRR of 28% but only a 1.3x multiple, revealing that the strong percentage came from a fast eighteen-month exit rather than a large profit.
Example
An infrastructure fund's annual report shows gross IRR of 14% and net IRR of 10% across the portfolio. The manager explains the four point spread in a footnote covering the management fee, fund audit costs and carry, which heads off the question at the investor meeting.
Think of it
“Gross IRR is return before fees-what the investments made before manager costs.
Formula
Calculation
Gross IRR is the discount rate at which the present value of all pre-fee cash flows equals zero. For a single investment made once and exited once, it simplifies to:
Gross IRR = (Exit Value / Investment)^(1 / Years) - 1
A fund invests $12,000,000 in a logistics business and sells it four years later for $27,000,000, with no cash flows in between.
Multiple = $27,000,000 / $12,000,000 = 2.25x
Gross IRR = 2.25^(1/4) - 1 = 1.2247 - 1 = 0.2247, or about 22.5%
Now apply fees. The gross profit is $27,000,000 - $12,000,000 = $15,000,000, and the manager takes carried interest of 20%, which is $3,000,000. Investors receive $24,000,000, a multiple of 2.0x, and the net IRR is 2.0^(1/4) - 1 = 18.9%. The 3.6 percentage point difference between 22.5% and 18.9% is the carry alone, before any management fee is charged.Case study
Seen in the real world.
Meridian Slate Capital is a fictional mid-market buyout firm used here purely as an illustrative example. When it began fundraising for a $400 million fund, its marketing deck led with a gross IRR of 31% across nine realised deals, a figure that put it comfortably in the upper part of its peer group.
One prospective investor built its own model from the underlying cash flows and found that the net IRR to limited partners had been 19%. The twelve point gap came from three sources: management fees charged on committed rather than invested capital, carried interest on each deal, and a set of transaction fees the fund had retained. None of it was hidden, but none of it was on the front page either.
The investor did not walk away. Instead it committed on the condition that fees were charged on invested capital and that transaction fees were offset against the management fee, changes that would have lifted the historic net IRR by roughly two percentage points. Meridian accepted, and afterwards began quoting gross and net side by side in every presentation, which its partners found made investor conversations shorter rather than harder.
Watch out
Common mistakes.
- Comparing one fund's gross IRR against another's net IRR. That comparison is meaningless, because the two numbers are measured before and after several percentage points of cost.
- Reading a high gross IRR as a large profit. A deal that returns 1.2x in nine months produces a spectacular annualised rate on a modest amount of money, which is why multiple of invested capital must be read alongside it.
- Assuming gross IRR includes deal costs. Definitions vary between managers, and some deduct transaction and financing costs at the asset level while others do not, so the basis should always be confirmed.
Questions
People also ask.
Why do managers quote gross IRR at all?
Because it shows investment performance separately from fund structure and fee terms, which is genuinely useful when judging whether a team can pick and improve assets.
How big should the gap between gross and net IRR be?
In private equity it is commonly between three and eight percentage points, and a gap far outside that range deserves an explanation.
Does gross IRR account for money sitting uninvested?
No, and that is a key limitation, since capital committed but not yet drawn earns little, which drags on what an investor experiences even though gross IRR never sees it.
