IRR and Equity Multiple
IRR emphasizes timing; equity multiple emphasizes how much cash comes back relative to equity invested.
Definition
Internal Rate of Return is the discount rate that makes the present value of projected investment cash flows equal to the initial equity invested. Equity multiple equals total equity distributions divided by total equity contributions. A 2.0x multiple means two dollars were returned for every dollar contributed, before considering context and timing.
Beginner Explanation
Suppose two investments both return $2 for every $1 invested. One takes three years; the other takes ten. Their equity multiple is the same, but the faster investment generally has a higher IRR because money returned earlier can be used again. Neither number alone explains risk, effort, taxes, or what happened between purchase and sale.
Professional Explanation
IRR incorporates timing and can compare uneven multi-year cash flows, but it is sensitive to hold period, early distributions, refinancing proceeds, and assumptions about future events. Equity multiple is easier to understand but ignores time value. Analysts examine both alongside cash-on-cash return, profit, leverage, downside cases, and the source of return. A high modeled IRR created mainly by a short hold or optimistic exit may be less durable than a moderate return supported by operating cash flow.
Why It Matters
These measures help investors compare uses of equity, communicate business plans, and evaluate whether value creation came from income growth, leverage, market movement, or timing. They should not be used as guarantees or compared without consistent assumptions. Fees, taxes, capital calls, reinvestment, and risk can change the investor's actual experience.
Real-World Example
An investor contributes $1 million, receives $100,000 annually for four years, and $1.6 million in year five. Total distributions are $2 million, so equity multiple is 2.0x. IRR additionally reflects when each distribution arrived.
Common Mistakes
- Comparing IRRs with different hold assumptions.
- Believing a high IRR proves low risk.
- Ignoring capital calls when calculating equity multiple.

Practical Exercise
Compare two 2.0x investments: one returns all cash in year three, the other in year eight. Explain why their multiples match but IRRs differ.

内部回报率（IRR）与股权倍数
IRR 强调时间，股权倍数强调相对于投入股权收回了多少现金。
定义
内部回报率是使预计投资现金流现值等于初始股权投入的折现率。股权倍数等于股权总分配除以股权总投入。2.0 倍表示每投入一美元共收回两美元，但仍需结合具体背景与时间理解。
先用简单语言理解
假设两项投资都是每投入 1 美元最终收回 2 美元，一项需要三年，另一项需要十年。两者股权倍数相同，但较快收回资金的投资通常拥有更高 IRR，因为较早返回的资金可以再次使用。任何一个数字都不能单独解释风险、工作量、税务或买入与出售之间发生了什么。
专业解释
IRR 纳入时间因素，可以比较不均匀的多年现金流，但对持有期、早期分配、再融资收入和未来事件假设非常敏感。股权倍数更容易理解，却忽略时间价值。分析人员会把两者与现金回报率、利润、杠杆、下行情景和回报来源共同研究。主要由短持有期或乐观退出创造的高模型 IRR，可能不如由运营现金流支持的中等回报可靠。
为什么重要
这些指标帮助投资人比较股权资金用途、沟通商业计划，并判断价值创造来自收入增长、杠杆、市场变化还是时间安排。但它们不能作为保证，也不能在假设不一致时直接比较。费用、税务、追加资本、再投资和风险都会改变投资人的实际结果。
实际案例
投资人投入 100 万美元，连续四年每年获得 10 万美元，第五年获得 160 万美元。总分配为 200 万美元，股权倍数为 2.0 倍；IRR 还会反映每笔分配发生的时间。
常见错误
- 比较持有期假设不同的 IRR。
- 认为高 IRR 能证明低风险。
- 计算股权倍数时忽略追加资本。

- DCF
- Present value
- Hold period

- 杠杆后 IRR 与 MOIC
- Broker
- 投资人回报与总倍数
- Interview
- IRR 反映时间，股权倍数反映每一美元股权对应的总现金回收。
常用缩写
- IRR — Internal Rate of Return
- EM — Equity Multiple
- MOIC — Multiple on Invested Capital
