The internal rate of return (IRR) serves as a critical metric for evaluating the profitability of potential investments, yet determining what constitutes a "good" figure remains one of the most nuanced challenges in financial analysis. Also, unlike a fixed benchmark such as a risk-free rate, a satisfactory IRR is entirely relative, shifting dramatically based on the asset class, the prevailing economic climate, the project’s risk profile, and the investor’s specific cost of capital. Understanding this relativity is the first step toward making capital allocation decisions that genuinely build wealth rather than simply clearing an arbitrary hurdle.
People argue about this. Here's where I land on it.
The Mechanics Behind the Metric
Before defining a target, Make sure you grasp what the internal rate of return actually calculates. It matters. At its core, IRR is the discount rate that makes the net present value (NPV) of all cash flows—both positive and negative—from a particular project equal to zero. In simpler terms, it represents the annualized effective compounded return rate an investor can expect to earn on the capital deployed, assuming all interim cash flows are reinvested at that same rate.
Real talk — this step gets skipped all the time.
This assumption of reinvestment is precisely where the metric draws both its power and its criticism. A project requiring $10 million and returning $15 million looks different on an NPV basis than a $100,000 project returning $200,000, but their IRRs might tell a similar story about efficiency. While NPV provides a dollar value of wealth creation, IRR offers a percentage yield that allows for easy comparison across projects of vastly different scales. Still, the "reinvestment rate assumption" implies that if a project yields 25% IRR, the model assumes you can consistently reinvest the interim profits at 25%—a feat often impossible in lower-yield environments The details matter here..
The Golden Rule: IRR vs. Cost of Capital
The most fundamental rule for assessing a good internal rate of return is the comparison against the Weighted Average Cost of Capital (WACC) or the investor’s required rate of return (hurdle rate).
- IRR > WACC: The project creates value. The spread between the two represents the economic profit generated per dollar invested.
- IRR = WACC: The project breaks even on an economic basis, covering the cost of debt and equity but generating no excess return for shareholders.
- IRR < WACC: The project destroys value. Even if it generates accounting profit, it fails to compensate capital providers adequately for the risk undertaken.
Because of this, a "good" IRR is, at minimum, any figure that comfortably exceeds the cost of capital. If a corporation’s WACC is 8%, a project yielding 12% might be acceptable, but one yielding 20% is objectively "better" because it provides a wider margin of safety against forecasting errors.
Contextual Benchmarks by Asset Class
Because risk and liquidity vary wildly across investment types, universal IRR targets are misleading. What looks like a spectacular return for a core real estate asset might be a disaster for a venture capital fund It's one of those things that adds up..
Private Equity and Venture Capital
In the high-risk world of private equity (PE), general partners typically target 20% to 25% gross IRR (before fees) for buyout funds. For venture capital (VC), where the failure rate of portfolio companies is high and the power law dictates that one winner must cover many losers, target gross IRRs often exceed 30%. Net IRR to limited partners (after management fees and carried interest) usually settles lower, often in the 15%–20% range for top-quartile funds. Anything below the public market equivalent (PME)—essentially the return of a comparable public index—is considered a failure in this asset class.
Commercial Real Estate
Real estate IRR targets are heavily stratified by strategy:
- Core / Core-Plus: Stabilized, high-quality assets in prime markets. Target IRR: 6% – 10%. These behave like bonds with inflation hedges.
- Value-Add: Properties requiring renovation or repositioning. Target IRR: 12% – 18%. The premium compensates for execution and leasing risk.
- Opportunistic / Development: Ground-up construction or distressed assets. Target IRR: 18% – 25%+. High use and binary outcomes (entitlements, construction delays) demand high hurdles.
Infrastructure and Energy
These assets offer long-dated, contracted cash flows (often inflation-linked). Because they exhibit lower beta to economic cycles, investors accept lower returns for stability. Target IRRs typically range from 8% – 14%, depending on the regulatory regime and merchant vs. contracted revenue exposure.
Corporate Capital Budgeting
For a standard corporation evaluating a new factory, machinery, or product line, the hurdle rate is usually the WACC plus a risk premium. A "good" project IRR might be 12% – 15% for a company with a 9% WACC. On the flip side, strategic projects (e.g., entering a new market for defensive reasons) might be approved at lower IRRs if they tap into optionality not captured in the base case model.
The Critical Distinction: IRR vs. MOIC
Relying solely on IRR can lead to the "duration trap.Still, " A project returning 1. 5x your money in six months might show an IRR of 100%+, while a project returning 3x your money over ten years might show an IRR of only 12%.
This is why sophisticated investors pair IRR with Multiple on Invested Capital (MOIC), also known as the Equity Multiple It's one of those things that adds up..
- MOIC = Total Distributions / Total Capital Invested
A "good" investment usually requires both a strong IRR (speed of return) and a strong MOIC (magnitude of return). Even so, * High IRR / High MOIC: The "Holy Grail. " Good for liquidity, bad for long-term wealth compounding. Capital must be redeployed immediately at high rates to sustain the track record. " Excellent for long-term holders (endowments, pension funds) who do not need immediate liquidity and benefit from tax deferral Worth knowing..
- High IRR / Low MOIC: "Quick flip.* Low IRR / High MOIC: "Compounders." Rare, usually found in early-stage winners or perfectly timed cyclical exits.
Factors That Distort the "Good" Label
Several technical nuances can make an IRR look artificially attractive or unattractive Easy to understand, harder to ignore..
1. use Effects
In real estate and LBOs, debt amplifies equity IRR. A project with an unlevered IRR of 10% might show a levered IRR of 18% simply due to cheap debt. A "good" levered IRR must be stress-tested: What happens to the IRR if interest rates reset higher or occupancy drops? If the unlevered yield doesn't cover the debt service comfortably, the high levered IRR is a mirage Easy to understand, harder to ignore..
2. Timing of Cash Flows (The "J-Curve")
Private equity funds often show negative IRR in early years (the J-curve) because management fees are drawn before portfolio companies mature. Judging a fund "bad" based on Year 2 IRR ignores the asset class lifecycle. A good IRR here is measured at maturity (Year 10+), not interim And that's really what it comes down to..
3. Reinvestment Rate Fallacy
As mentioned earlier, standard IRR assumes reinvestment at the project's own IRR. Modified Internal Rate of Return (MIRR) corrects this by assuming reinvestment at the firm's cost of capital (or a safe rate). A project with a 30% IRR but a 1
but a 15% MIRR exposes the reinvestment fantasy. Beyond MIRR, two other distortions routinely mislead analysts. First, scale insensitivity: a $50,000 investment returning 40% IRR generates less absolute wealth than a $50 million project returning 12%. Also, iRR ignores dollar magnitude, making it dangerous for capital allocation when funds are constrained. Second, non-normal cash flows—where costs follow revenues, as in mining or pharmaceutical R&D—can produce multiple IRRs or none at all, rendering the metric mathematically ambiguous And that's really what it comes down to. Turns out it matters..
Context ultimately determines whether an IRR is "good." A 15% return might be exceptional for a mature real estate portfolio but mediocre for a venture fund betting on exponential growth. The metric must be evaluated alongside MOIC for magnitude, NPV for absolute value creation, and strategic fit for optionality Nothing fancy..
5% MIRR exposes the reinvestment fantasy. Here's the thing — beyond MIRR, two other distortions routinely mislead analysts.

The metric must be evaluated alongside MOIC for magnitude, NPV for absolute value creation, and strategic fit for optionality. In practice, the "holy grail" of high IRR and high MOIC remains rare precisely because markets are efficient enough to price away easy excess.
Not obvious, but once you see it — you'll see it everywhere Easy to understand, harder to ignore..
Which means, the label of "good" is not an inherent property of the IRR figure itself but a judgment call based on a holistic analysis. Even so, it requires peeling back layers of take advantage of, timing, and scale to understand the true quality of the return. The most disciplined investors resist the seduction of a single, headline number, instead building a mosaic of metrics and context to separate genuine alpha from accounting illusion.
