Gross IRR is the internal rate of return calculated at the portfolio level, before any management fees, carried interest, or fund expenses are deducted. It measures the raw investment performance of a fund’s deals, isolating the GP’s ability to pick, structure, and exit investments from the economics of running a fund.
What Gross IRR Captures
Gross IRR answers a specific question: how well did the general partner invest the capital that went into deals? The cash flows used in the calculation are:
- Outflows: the actual capital deployed into portfolio companies, at the time of each investment.
- Inflows: the proceeds received from exits, dividends, recapitalizations, and interest, plus the current fair market value of unrealized holdings.
Management fees, organizational expenses, and carry are excluded entirely. This gives a clean read on investment selection and value creation.
Gross IRR vs. Net IRR
The difference between gross and net IRR is the cost of accessing the GP’s investment program. For a fund running the industry-standard 2% management fee on committed capital and 20% carry above an 8% preferred return, the gross-to-net spread typically runs 500-800 basis points.
Consider a concrete example. A fund with a 25% gross IRR and a 2-and-20 structure might deliver roughly 18-19% net IRR to limited partners. The exact spread depends on deployment pace, hold periods, the timing of exits, and whether the fund charges fees on committed or invested capital.
For first-time fund managers, the spread can be wider. A $100M fund charging 2% on commitments collects $2M annually in management fees, which represents a heavier proportional drag than the same rate on a $1B fund.
Where Gross IRR Is Most Useful
Gross IRR earns its place in three specific contexts:
Evaluating investment skill. When an LP wants to assess whether a GP can generate alpha at the deal level, gross IRR strips away structural differences between funds. Two GPs with identical gross IRRs but different fee structures will show different net returns, but their investment capability is comparable.
Deal attribution. GPs often report gross IRR at the individual deal level in their track record. This lets LPs see dispersion across the portfolio: how many deals drove the fund’s return, how many were write-offs, and whether performance was concentrated or broad-based.
Cross-fund comparison. When comparing a GP’s performance across fund vintages, gross IRR provides consistency. Fee structures may evolve from Fund I to Fund IV, but gross IRR tracks the underlying investment engine.
The Limitations
Gross IRR has the same timing sensitivities as any IRR calculation. A quick early exit at a high multiple can inflate the gross IRR of the entire portfolio even if subsequent deals underperform.
It also says nothing about what LPs actually receive. A fund with a dazzling gross IRR but an aggressive fee structure, high GP commitment recycling, or unusual expense provisions may deliver a disappointing net IRR. This is why institutional LPs always ask for both numbers and pay closest attention to the net figure when making allocation decisions.
For a complete picture, pair gross IRR with MOIC at the deal level and DPI at the fund level to understand both the magnitude and the realization status of returns.
Frequently Asked Questions
Why do GPs report gross IRR?
Gross IRR isolates investment skill from fund economics. It shows how well the GP selected and managed investments without the noise of fee structures, fund size, or carry terms. This makes it useful for evaluating a GP's investment acumen independently of their business model.
How much lower is net IRR than gross IRR?
The spread depends on fund size, fee structure, and performance level. For a standard 2-and-20 buyout fund, the gap typically runs 500-800 basis points. Smaller funds with higher fee ratios may see wider spreads. High-performing funds narrow the gap because management fees become a smaller proportion of total returns.
Is gross IRR or net IRR more important?
For LPs making allocation decisions, net IRR matters more because it reflects actual returns received. For evaluating a GP's investment capability across different fund structures or when comparing a GP's deal-level track record, gross IRR is more informative. Sophisticated investors examine both.
