Answer:
The cost of retained earnings is 10.83%
Step-by-step explanation:
The constant growth model assumes that the dividends grow at a constant rate indefinitely and the DCF approach is used to calculate the price of a stock that has constant dividend growth.
The formula to calculate the Price of such a stock today using the constant growth model is,
P0 = D0 * (1+g) / r - g
We will plug in the values that are known to calculate the required rate of return on such a stock.
45 = 2.5*(1+0.05) / r - 0.05
45 * (r- 0.05) = 2.625
45r - 2.25 = 2.625
45r = 2.625 + 2.25
r = 4.875 / 45
r = 0.1083 or 10.83%
