Cost of Equity

Definition

The return shareholders require to compensate for the risk of owning the stock.

How It Works

Most commonly estimated via CAPM (Re = Rf + β × MRP) or by rearranging the Gordon Growth Model (Re = D1/P + g).

Example

Using CAPM with Rf=3%, β=1.1, MRP=6%: Re = 3% + 1.1×6% = 9.6%.

Common Misconceptions

  • Cost of equity equals the dividend yield
  • It is always lower than cost of debt

Yes. Rearrange the Gordon Growth Model: Re = D1/P0 + g. This method works well for stable, dividend-paying companies but requires a reliable growth rate estimate.
