Cost of Capital
Chapter 7 1st Paper Samira Sharmin Mahbub Lecturer, Finance Banking & Insurance
Concept of Capital Budgeting
Mr. X is thking to start a business.
He need capital for that.
He can collect that from external sources fund
Long term loan
Preferred stock
Common Stock
But all these sources incur cost.
And the company has to bear this cost for long term
So selecting wrong source of funding hamper business, its owners, employees and investors..
Definition of Cost of Capital
L. J. Gitman defines the cost of capital as ‘the rate of return a firm must earn on its investment so the market value of the firm remains unchanged’.
According to Ezra Solomon, ‘the cost of capital is the minimum required rate of earnings or the cut-off rate of capital expenditure’.
The definition given by Keown et al. refers to the cost of capital as
‘the minimum rate of return necessary to attract an investor to purchase or hold a security’.
Cost of capital is also referred to as the break-even rate, minimum rate, cut-off rate, target rate, hurdle rate, standard rate, etc.

Concept of Cost of Capital
1. Common Stock
• General shareholders are owner of the company
• They can participate in the management of the company
• They only get dividend from profit and its not guaranteed every year
• They have voting right
2. Preferred Stock
• Get a specified rate of dividend
• Get dividend before all
• They are partially owner
• They don’t enjoy any voting right

Sources of Capital
3. Bond or Debenture
Every year specified rate of interest is paid at specified time
It is transferable
Interest is deducted before tax and net income
Holders don’t participate in Management and enjoys no voting right
4. Retained Earning
This does not incur any direct expanse
It has opportunity cost
Personal tax is adjusted with this
Usually spend for business expansion
Computation of cost of Capital
This computation of cost of capital consists of two important parts
Measurement of Specific cost
Measurement of overall cost of capital
Regarding specific cost we will start with – Cost of Equity
Cost of Equity : Common Stock
The cost of common stock is common stockholders' required rate of return.
We are going to learn 3 types of Cost of Common Stock calculation
Zero dividend growth model
Constant growth model

Bata company every year gives BDT 10 dividend which in remain unchanged in future and market price is Tk. 110 then what will be the cost of common stock. (9.09%)
Mr. X purchased ABC companies share at Tk. 150 each and after a year sold that at Tk. 200 each. ABC company paid Tk. 15 dividend that year. What is the return for Mr. X from that share in taka.

Capital Asset Pricing Model
The Capital Asset Pricing Model (CAPM) is a model that describes the relationship between the expected return. The return on the
investment is an unknown variable that has different values associated with different probabilities. and risk of investing in a security.
𝑲 𝒆 =
𝑹 𝒇
+ β ( 𝑹 𝒎 - 𝑹 𝒇 )
Where
𝑲
𝒆 = Cost of Equity𝑹 𝒇
= Risk free rate of return𝑹 𝒎
= Market returnβ = Beta of investment
Condition of CAPM
Investors are expected to make decisions based solely on risk-return assessments (expected returns and standard deviation measures).
The purchase and sale transactions can be undertaken in infinitely divisible units.
Investors can sell short any number of shares without limit.
There is perfect competition and no single investor can influence prices, with no transactions costs, involved
Personal income taxation is assumed to be zero.
Investors can borrow/lend, the desired amount at riskless rates.
Example
ABC companies risk free rate of return is 6.5%, Market return is 13% and beta is 1.62. What will be the cost of equity of ABC company?
ABC companies beta is 0.9, treasury bill rate of return is 7%, Market risk is 10%. What will be the cost of equity of ABC company? ( 16%)

Weighted Average Cost of Capital (WACC)
Weighted Average Cost of Capital (WACC) represents its blended cost of capital across all sources, including
common shares
preferred shares and
debt
The cost of each type of capital is weighted by its percentage of total capital and they are added together.
