IRR (Internal Rate of Return)

What Is IRR?

The internal rate of return (IRR) is the discount rate at which the present value of future cash flows from an investment equals the initial cost of that investment. As Investopedia explains, it is the annualised return an investor earns over the life of an investment, accounting for the timing of all cash inflows and outflows.

IRR is the dominant return metric in private equity because it captures both the magnitude and the speed of returns. An investment that doubles capital in two years has a much higher IRR than one that doubles capital in five years — even though both achieve a 2x multiple.

How IRR Is Calculated

The IRR is the rate (r) that solves:

0 = CF₀ + CF₁/(1+r)¹ + CF₂/(1+r)² + … + CFₙ/(1+r)ⁿ

Where CF₀ is the initial investment (negative), and CF₁ through CFₙ are the subsequent cash flows (distributions, dividends, and exit proceeds).

There is no closed-form solution — IRR is calculated through iterative approximation (trial and error, essentially). Financial software and spreadsheets use built-in functions (XIRR in Excel) that handle the computation.

Gross IRR vs. Net IRR

	Gross IRR	Net IRR
Fees	Before management fees and carried interest	After all fees and carry
Perspective	Fund manager’s investment performance	Limited partner’s actual return
Use	Performance attribution, deal-level analysis	LP reporting, fund comparison
Typical spread	3–8 percentage points higher than net	The return LPs actually receive

Net IRR is what matters to investors, but gross IRR is useful for evaluating the quality of a manager’s investment decisions independent of fee structures. IRR is also a central metric in M&A valuation methods such as discounted cash flow analysis.

IRR Benchmarks in Private Equity

Target and achieved IRRs vary by strategy:

Strategy	Target Net IRR	Typical Range
Large-cap buyout	15–20%	12–25%
Mid-market buyout	20–25%	15–30%
Growth equity	20–30%	15–35%
Venture capital	25–35%	Highly variable
Distressed / turnaround	20–30%	15–40%

Top-quartile PE funds consistently deliver net IRRs above 20%, while median funds typically achieve 12–18%.

IRR vs. MOIC

IRR and multiple of invested capital (MOIC) are complementary metrics:

• IRR rewards speed — a quick flip at modest multiple can produce an impressive IRR
• MOIC rewards magnitude — a patient investment that generates a large multiple scores well on MOIC regardless of duration
• Best investments deliver strong performance on both metrics

A common tension: a fund can boost its IRR by exiting investments quickly, but this may sacrifice total value creation. Conversely, holding investments longer to maximise MOIC may dilute IRR. Sophisticated LPs evaluate both metrics in combination.

Limitations of IRR

• Reinvestment assumption — IRR implicitly assumes interim cash flows can be reinvested at the IRR itself, which may be unrealistic for very high-return investments (Corporate Finance Institute)
• Sensitivity to timing — small changes in the timing of cash flows can significantly affect IRR, making it possible to manipulate through subscription line facilities or delayed capital calls
• Not additive — you cannot simply average the IRRs of individual investments to get a portfolio IRR; portfolio IRR must be calculated from aggregate cash flows
• Multiple solutions — investments with alternating positive and negative cash flows can produce multiple mathematical IRRs

IRR in Asia Pacific

Private equity IRR expectations in Asia Pacific vary significantly by market and strategy, as detailed in our overview of private equity trends in APAC. Developed market buyouts (Australia, Japan) target returns comparable to global benchmarks, while growth equity investments in emerging Southeast Asian markets may carry higher target IRRs to compensate for currency risk, political risk, and liquidity constraints. Currency effects can significantly impact IRR for cross-border investors — a strong local-currency return may be eroded by adverse exchange rate movements when translated back to the fund’s base currency. AI-native platforms like Amafi help PE firms evaluate opportunities across the region with the financial rigour needed to underwrite target returns.
