The heart of investing isn’t the numbers — it’s the baseline. CAPM establishes a baseline for expected return, while WACC anchors a firm’s cost of capital.


1. CAPM: Finding the Balance Between Risk and Expected Return

Adjust the risk-free rate, beta, and market return. You’ll develop a feel for exactly which variables cause expected return to shift dramatically.

CAPM (자본자산가격모형) 계산기

자기자본비용 (Ke)
11.30%
Ke = 3.5% + 1.2 × (10% - 3.5%)

Observation point: the higher the beta, the greater the impact of the risk premium. Same market environment — but sensitivity drives the difference in returns.


2. WACC: Setting the Investment Hurdle Rate

Adjust the ratio of equity to debt financing. Watch how the capital structure reshapes the firm’s investment threshold.

WACC (가중평균자본비용) 계산기

가중평균자본비용 (WACC)
8.80%
부채비율: 40.0% | 자기자본비율: 60.0%

Q. If WACC increases, what happens to the bar for approving new investment projects? A. The hurdle rate rises, making it harder for projects to clear the approval threshold.


Finance is the discipline of setting baselines. Once you develop a feel for the relationship between return and cost of capital, the numbers stop being abstract.
