Net IRR
Net IRR is the money-weighted internal rate of return calculated from investor-level private-fund cash flows after applicable fund-level fees, expenses and carried interest, together with ending value under the stated methodology.
Net IRR moves the analysis to the LP level
Gross IRR asks how the investment program performed before specified fund economics.
Net IRR asks a more investor-centered question: what money-weighted return resulted after applicable fees, expenses and carried interest?
ILPA’s glossary describes Net IRR as the dollar-weighted internal rate of return generated by an investment in the fund after management fees and carried interest, incorporating cash-flow timing and ending value.[1]
Net IRR uses timing, not just totals
A fund can call $100, return $150 and show a different Net IRR depending on whether the $150 arrives two years later or eight years later.
That is because IRR solves for a rate that links dated cash flows and ending value.
Net IRR therefore captures a dimension that TVPI does not: how long investor capital was actually outstanding under the calculation convention.
Fees and carry create the gross-to-net spread
Management fees, partnership expenses and carried interest reduce the value available to LPs compared with gross investment performance.
A simplified example:
- gross investment results are strong
- the fund charges management fees over several years
- successful exits trigger carried interest
- remaining assets contribute to ending NAV
The resulting Net IRR will generally be below Gross IRR because the LP cash flows reflect those fund economics.
The size of the gap varies by fund and should be interpreted with the governing documents rather than assuming a fixed haircut.
Subscription facilities complicate time-based comparisons
A subscription line can allow a fund to make investments before calling capital from LPs.
That can shorten the measured period between the LP contribution and the later distribution, which can raise an IRR calculated from LP cash flows.
ILPA’s current Performance Template includes reporting designed to show performance with and without the impact of fund-level subscription facilities.[2][3]
This is an important comparability issue because the investment’s economic holding period can begin before the LP’s capital is formally called.
Net IRR is not necessarily identical for every LP
Investor-level economics can differ because of:
- fee discounts
- side-letter terms
- closing dates
- excuse or exclusion rights
- tax or regulatory structuring
- different commitment sizes
A reported fund Net IRR is useful, but it should not automatically be assumed to equal the exact realized return of every individual LP account.
Net IRR and TVPI can tell different stories
Consider two funds:
- Fund A: 18% Net IRR and 1.8x TVPI
- Fund B: 15% Net IRR and 2.2x TVPI
Fund A may have returned capital faster. Fund B may have created more total value per dollar but over a longer period.
Neither metric alone settles which outcome is preferable.
DPI, RVPI, fund age, risk and benchmark context are still necessary.
Common mistakes
“Net IRR is the same as annual portfolio return.”
No. It is a money-weighted return derived from dated private-fund cash flows and ending value.
“Net IRR removes every investor-specific difference.”
No. Side letters and investor circumstances can create differences.
“A higher Net IRR always means a higher multiple.”
No. Faster capital recycling or earlier exits can raise IRR without producing the highest multiple.
“Net IRR is immune to financing choices.”
No. Subscription-line timing can affect the calculation.
Example
An investor evaluating Net IRR should identify the stated calculation, valuation or governing-document convention before comparing the figure or structure across funds.
Professional note
Net IRR is usually more relevant than Gross IRR for understanding the economics delivered to LPs, but it remains a timing-sensitive measure. A serious comparison pairs it with TVPI, DPI, vintage year, cash-flow conventions and disclosure about subscription facilities.

Carried interest is a contractual allocation of private-fund profits to the general partner, sponsor or affiliated carry vehicle, usually after specified return-of-capital and performance conditions are satisfied.
- Internal Rate of Return (IRR)
Internal rate of return (IRR) is the discount rate that makes the net present value of an investment’s cash inflows and outflows equal zero.

Total value to paid-in (TVPI) is the ratio of cumulative distributions plus remaining fund value to the capital investors have contributed.
- Gross IRR
Gross IRR is an internal rate of return calculated before specified fund-level fees, expenses and carried interest, using the cash flows and valuation methodology defined by the reporting convention.
