Formula & Methodology
The cost of capital (CoC) is calculated using the Capital Asset Pricing Model (CAPM):
CoC = Rf + β * (E[Rm] – Rf)
Where:
- Rf = Risk-free rate
- β = Beta (systematic risk of the asset)
- E[Rm] = Expected market return

What is beta (β)?
Beta is a measure of an asset’s systematic risk, i.e., the risk that cannot be diversified away. A beta of 1 indicates that the asset’s returns are expected to move with the market, while a beta greater than 1 indicates higher volatility.
