The cost of raising capital through retained earnings is the cost of raising capital through issuing new common stock.

The cost of equity using the CAPM approach

The yield on a three-month T-bill is 3%, the yield on a 10-year T-bond is 3.88%. The market risk premium is 7.37% and the Wilson Company has a beta of 0.73. Using the Capital Asset Pricing Model (CAPM) approach, Wilsons cost of equity is .

The cost of equity using the bond yield plus risk premium approach

In contrast, the Kennedy Company is closely held and, therefore, cannot generate reliable inputs with which to apply the CAPM method to estimate its cost of internal equity (retained earnings). However, its management knows that its outstanding bonds are currently yielding 8.91%, and the firms analysts estimate that the risk premium of its stocks over its bonds is currently 1.34%. As result, Kennedys cost of internal equity (rss)based on the own-bond-yield-plus-judgemental-risk-premium approachis:

11.28%

12.81%

12.30%

10.25%

The cost of equity using the discounted cash flow (or dividend-yield-plus-growth-rate) approach

Tucker Enterprisess stock is currently selling for $24.25 per share, and the firm expects its per-share dividend to be $2.50 in one year. Analysts project the firms growth rate to be constant at 6.80%. Using the discounted cash flow (or dividend-yield-plus-growth-rate) approach, what is Tuckers cost of internal equity?

14.54%

17.11%

17.97%

23.10%

Estimating growth rates

It is often difficult to estimate the expected future dividend growth rate for use in estimating the cost of existing equity using the DCF (or dividend-yield-plus-growth-rate) approach. In general, there are three available methods to generate such an estimate:

	Carry forward a historical realized growth rate, and apply it to the future.
	Locate and apply an expected future growth rate prepared and published by security analysts.
	Use the retention growth model.

Suppose Tucker Enterprisess is currently distributing 55% of its earnings as cash dividends. It has also historically generated an average return on equity (ROE) of 10.50%. It is reasonable to estimate Tuckers growth rate is .
