Worked Examples

Example 1: PE Fund Investment Return Calculation

Problem: $10M investment, 5-year hold, exit at 3.5× ($35M). 2% annual mgmt fee, 20% carry, 8% hurdle. Calculate LP returns.

Solution: Investment:\n- Amount: $10,000,000\n- Holding period: 5 years\n- Exit: $35,000,000 (3.5× MOIC)\n\nGross Returns:\n- Total return: $35M - $10M = $25M\n- Gross MOIC: 3.5×\n- Gross IRR: (3.5)^(1/5) - 1 = 28.5%/year\n\nManagement Fees:\n- Annual: 2% of $10M = $200,000\n- Total (5 years): $1,000,000\n\nHurdle Calculation:\n- Hurdle rate: 8%/year\n- Hurdle amount: $10M × 1.08^5 = $14.69M\n- Return of capital: $10M\n- Preferred return: $4.69M\n\nProfit Distribution:\n- Total proceeds: $35M\n- Less: Return of capital: $10M\n- Profit available: $25M\n- Less: Management fees: $1M\n- Profit for carry calc: $24M\n\nCarried Interest:\n- Profit above hurdle: $35M - $14.69M = $20.31M\n- GP carry (20%): $20.31M × 0.2 = $4.06M\n\nLP Distribution:\n- Return of capital: $10M\n- Preferred return: $4.69M\n- Sh

Result: LPs: 3.09× / 25.3% IRR (net of fees) | GPs: $5.06M fees+carry | Excellent returns for 5-year hold

Frequently Asked Questions

What is IRR in private equity?

IRR (Internal Rate of Return) is annualized return rate accounting for timing of cash flows. Formula: Investment × (1 + IRR)^Years = Exit value. Example: Invest $10M, exit at $35M in 5 years. $10M × (1 + IRR)^5 = $35M. IRR ≈ 28.5%/year. PE target: >20% IRR. Why IRR over absolute return: Time value of money. 3× in 3 years (IRR 44%) is better than 3× in 10 years (IRR 11.6%).

What is MOIC (Multiple on Invested Capital)?

MOIC = Exit Value / Investment. Simpler than IRR; ignores time. Example: Invest $10M, exit $30M = 3× MOIC. PE targets: 2.5-3× minimum. MOIC is transaction multiple. Use both: IRR measures annualized return (comparable to stock market), MOIC measures absolute gain (easy to understand). 2× in 3 years (IRR 26%) may beat 4× in 10 years (IRR 14.9%) from IRR perspective but MOIC prefers 4×.

What is a good IRR for private equity?

Target IRR varies by strategy. Buyout (LBO): 20-25%. Growth equity: 25-30%. Venture capital: 30%+ (higher risk). Top-quartile funds: >25%. Median: 12-15%. Below 10%: Underperforming (S&P 500 is ~10%/year). Context matters: 15% IRR during recession is good; 15% during boom is mediocre. LPs allocate to PE expecting premium over public markets (illiquidity premium + value creation).

How do I interpret the result?

Results are displayed with a label and unit to help you understand the output. Many calculators include a short explanation or classification below the result (for example, a BMI category or risk level). Refer to the worked examples section on this page for real-world context.

No. All calculations run entirely in your browser using JavaScript. No data you enter is ever transmitted to any server or stored anywhere. Your inputs remain completely private.

Why might my result differ from another tool or reference?

Differences typically arise from rounding conventions, the specific version of a formula (for example, simple vs compound interest), or unit inconsistencies between inputs. Check that both tools are using the same formula variant and the same units. The References section links to the authoritative source behind the formula used here.

Background & Theory

The Private Equity IRR Multiple & Waterfall Estimator applies the following established principles and formulas. Finance and investing rest on the foundational concept of the time value of money: a dollar received today is worth more than a dollar received in the future, because present funds can be deployed to earn a return. This principle underlies virtually every valuation technique in modern finance. The future value of a present sum P growing at rate r over n periods is expressed as FV = P(1 + r)^n, while the present value of a future cash flow FV is PV = FV / (1 + r)^n. Compound growth amplifies returns significantly over long horizons, a dynamic often described as the eighth wonder of the world. Net Present Value (NPV) extends these mechanics to evaluate investment projects by summing the present values of all expected cash flows minus the initial outlay: NPV = sum[CF_t / (1 + r)^t] - C_0. A positive NPV indicates the project creates value above the required return. The Internal Rate of Return (IRR) is the discount rate that sets NPV to zero, providing a single percentage benchmark for project comparison. The risk-return tradeoff is the central tension of investment theory. Higher expected returns generally require accepting greater uncertainty. Harry Markowitz formalized this in Modern Portfolio Theory by demonstrating that portfolio variance can be reduced through diversification when assets are imperfectly correlated. The efficient frontier represents the set of portfolios offering the maximum return for a given level of risk. The Capital Asset Pricing Model (CAPM) extends this by introducing the market portfolio as a reference, defining expected return as E(r) = r_f + beta * (E(r_m) - r_f), where beta measures an asset's sensitivity to systematic market risk. Asset classes — equities, fixed income, real assets, and alternatives — differ in their return profiles, liquidity, and correlations. Strategic asset allocation determines long-run target weights based on investor objectives and risk tolerance, while tactical allocation permits short-run deviations to exploit perceived mispricings. Discount rates used in valuation models must reflect the cost of capital appropriate to the risk of the cash flows being discounted, a point stressed in corporate finance texts from Brealey, Myers, and Allen through to Damodaran.

History

The history behind the Private Equity IRR Multiple & Waterfall Estimator traces back through the following developments. The formal practice of lending at interest dates to ancient Mesopotamia, where the Code of Hammurabi around 1750 BCE regulated interest rates on grain and silver loans. Banking as an institutional activity took root in medieval Italy, with merchant bankers in Florence and Venice financing trade across Europe through instruments such as bills of exchange. The Medici family operated one of the most sophisticated banking networks of the fifteenth century, pioneering double-entry bookkeeping and correspondent banking relationships. Organized equity markets emerged in the early seventeenth century. The Dutch East India Company (VOC), chartered in 1602, issued shares to the public and created the Amsterdam Stock Exchange — widely regarded as the world's first formal stock exchange. The VOC allowed investors to buy and sell shares freely, establishing the template for the joint-stock company. The period also produced the Dutch tulip mania of 1636 to 1637, one of history's first recorded speculative bubbles, in which tulip bulb futures contracts reached extraordinary prices before collapsing. England's financial revolution followed in the late seventeenth century with the founding of the Bank of England in 1694 and the development of government bond markets. The South Sea Bubble of 1720 illustrated the dangers of speculative excess and contributed to early securities regulation. Throughout the eighteenth and nineteenth centuries, industrialization created enormous demand for capital, fueling the expansion of stock exchanges in London, Paris, New York, and beyond. The New York Stock Exchange, formalized in 1817, became the world's dominant equities market by the twentieth century. The Great Crash of 1929 and subsequent Great Depression prompted the US Securities Act of 1933 and Securities Exchange Act of 1934, establishing the SEC and mandatory disclosure requirements. Harry Markowitz published his landmark portfolio selection paper in 1952, launching quantitative finance. The CAPM emerged in the 1960s through work by Sharpe, Lintner, and Mossin. John Bogle launched the first retail index fund in 1976, democratizing diversified investing and challenging active management orthodoxy.
