SOLVED PROBLEMS – COST OF CAPITAL
Problem 1
Calculate the cost of capital in the following cases:
i) X Ltd. issues 12% Debentures of face value Rs. 100 each and realizes Rs. 95 per Debenture.
The Debentures are redeemable after 10 years at a premium of 10%.
ii) Y. Ltd. issues 14% preference shares of face value Rs. 100 each Rs. 92 per share. The shares
are repayable after 12 years at par.
Note: Both companies are paying income tax at 50%.
Solution
(i) Cost of Debt
[Int + (RV – SV) / N] (1 – t)
kd
(RV + SV) / 2
Int = Annual interest to be paid i.e. Rs. 12
t = Company’s effective tax rate i.e. 50% or 0.50
RV = Redemption value per Debenture i.e. Rs. 110
N = Number of years to maturity = 10 years
SV = issue price per debenture minus floatation cost i.e. Rs. 95
[12 + (110 – 95) / 10] (1 – .5)
kd =
(110 + 95) / 2
[12 + 2.5](0.5) 7.25
= = = 7.43%
97.50 97.50
(ii) Cost of preference capital
D + (RV – SV) / N
kp
(RV + SV) / 2
Where,
D = Dividend on Preference share i.e. Rs. 14
SV = Issue Price per share minus floatation cost Rs. 92
N = No. of years for redemption i.e. 12 years
RV = Net price payable on redemption Rs. 100

14 (100 – 92) / 12
kp =
(110 + 95) / 2
14 + .67
=
95
= 15.28%
Problem 2
a) A company raised preference share capital of Rs. 1,00,000 by the issue of 10% preference share of
Rs. 10 each. Find out the cost of preference share capital when it is issued at (i) 10% premium, and
(ii) 10% discount.
b) A company has 10% redeemable preference share which are redeemable at 6the end of 10th
year
from the date of issue. The underwriting expenses are expected to 2%. Find out the effective cost of
preference share capital.
c) The entire share capital of a company consist of 1,00,000 equity share of Rs. 100 each. Its current
earnings are Rs. 10,00,000 p.a. The company wants to raise additional funds of Rs. 25,00,000 by
issuing new shares. The flotation cost is expected to be 10% of the face value. Find out the cost of
equity capital given that the earnings are expected to remain same for coming years.
Solution
(a) Cost of 10% preference share capital
(i) When share of Rs. 10 is issued at 10% premium
Kp = D / P0
= 10 / 11 x 100
= 9.09%
(ii) When share of Rs. 10 is issued at 10% discount
kp = PD / P0
= 10 / 9 x 100
= 11.11%
(b) The cost of preference share (face value = Rs. 100) may be found as follows:
D + (RV – SV) / N
kp =
(RV+ SV) / 2

3. FINANCIAL MANAGEMENT Solved Problems
Rushi Ahuja 3
In this case D = 10
RV = 100
SV = 100 – 2 = Rs. 98
10 + (100 – 98) / 10
kp =
(100 + 98) / 2
= 10.3%
(c) In this case, the net proceeds on issue of equity shares are Rs. 100 – 10 = Rs. 90 and earnings per
share is Rs. 10.
Cost of new equity is:
ke = D1 / p0
= 10 / 90 11.%
Problem 3
A company is considering raising of funds of about Rs. 100 lakhs by one of two alternative method,
viz., 14% institutional term loan or 13% non-convertible debentures. The term loan option would attract
no major incidental cost. The debentures would have to be issued at a discount of 2.5% and would
involve cost of issue of Rs. 1,00,000.
Advise the company as to the better option based on the effective cost of capital in each case. Assume a
tax rate of 50%.
Solution
Effective cost of 14% loan: In this case, there is no other cost involved and the company has to pay
interest at 14%. This interest after tax shield @ 50% comes to 7% only.
Effective cost of 13% NCD : In this case,
Annual Interest, I = Rs. 13
SV = 100 – 2.50 – 1.00
= 96.50
13 (1 – 5)
kd =
96.50%
= 6.74%
The effective cost of capital is lesser in case of 13% NCD.

Problem 4
The following figures are taken from the current balance sheet of Delaware & Co.
Capital Rs. 8,00,000
Share Premium 2,00,000
Reserves 6,00,00
Shareholder’s funds 16,00,000
12% irredeemable debentures 4,00,00
An annual ordinary dividend of Rs. 2 per share has just been paid. In the past, ordinary dividends have
grown at a rate of 10 per cent per annum and this rate of growth is expected to continue. Annual interest
has recently been paid on the debentures. The ordinary shares are currently quoted at Rs. 27.5 and the
debentures at 80 per cent. Ignore taxation.
You are required to estimate the weighted average cost of capital (based on marker values) for Delaware
& Co.
Solution
In order to calculate the WACC, the specific cost of equity capital and debt capital are to be calculated
as follows:
D1 Rs. 2 x 1.10
ke = + g = + 10 = 18%
P0 Rs. 27.50
The market value of equity is 80,000 x Rs. 27.50 = Rs. 22,00,000
I Rs. 12
kd = = = 15%
SV Rs. 80
The market value of debt is 4,00,000 x .80 = Rs. 3,20,000.
Now, the WACC is
(22,00,000 / 25,20,000) x .18 + (3,20,000/25,20,000) x .15 = .176 = 17.6%
Note: In this case, the dividend of Rs. 2 has just been paid. So, D0 = Rs. 2 and the D1, i.e. dividend
expected after one year from now will be D0 x (1 + g) = Rs. 2 x 1.10.

a) Determine the weighted average cost of capital of the company. It had been paying dividends at a
consistent rate of 20% per annum.
b) What difference will it make if the current price of the Rs. 100 share is Rs. 160?
c) Determine the effect of Income Tax on the cost of capital under both premises (Tax rate 40%).
Solution
a) Weighted average cost of capital of the company is as follows:
Sources of capital Cost of capital Proportion of total Weighted cost of
capital
Equity share capital 20% 4/20 4.00
12% debenture 12% 4/20 2.40
Term loan 18% 12/20 10.80
WACC 17.20
Therefore, weighted cost of capital (without consideration of the market price of Equity and not taking
into consideration the effect of Income Tax) is = 17.2% per annum.
b) When market price of equity shares is Rs. 160 (Face value Rs. 100), the cost of capital is:
D1 20
ke = =
p 160
= 12.5%
Weighted average cost of capital will therefore be:
Sources of capital Cost of capital Proportion of total Weighted cost of
capital
Equity share capital 12.5% 4/20 2.5%
12% debenture 12% 4/20 2.4%
18% Term loan 18% 12/20 10.8
WACC 15.7%
The above WACC is without taking into consideration the effect of Income Tax.
c) As interest on debenture and loans is an allowable deductible expenditure for arriving at taxable
income, the real cost to the company will be interest charges less tax benefit (assuming that the
company earns taxable income).
So, interest cost will be : Rate of interest (1 – t)
12% Debenture : 12 x 0.60 = 7.2%
18% Term loan : 18 x 0.60 = 10.8%

The opportunity cost of retained earnings is the dividends foregone by shareholders. Therefore, the firm
must earn the same rate of return on retained earnings as on the Equity Share Capital. Thus, the
minimum cost of retained earnings is the cost of equity capital i.e. kr = ke.
Problem 7
A Limited has the following capital structure:
Equity share capital (2,00,000 shares) Rs. 40,00,000
6% preference shares 10,00,000
8% Debentures 30,00,000
80,00,000
The market price of the company’s equity share is Rs. 20. It is expected that company will pay a
dividend of Rs. 2 per share at the end of current year, which will grow at 7 per cent for ever. The tax rate
may be presumed at 50 per cent. You are required to compute the following:
a) A weighted average cost of capital based on existing capital structure.
b) The new weighted average cost of capital if the company raises an additional Rs. 20,00,000 debt by
issuing 10 per cent debentures. The would result in increasing the expected dividend to Rs. 3 and
leave the growth rate unchanged but the price of share will fall to Rs. 15 per share.
c) The cost of capital if in (b) above, growth rate increases to 10 per cent.
Solutions
a) The cost of equity capital is
D1 Rs. 2
ke = + g = + 0.07
P0 Rs. 20
= 0.1 + 0.07 = .17 or 17%
The cost of 8% debentures, after tax is 8 (1 – 5) = 4%

The market price of equity share and debenture is Rs. 12 and Rs. 93.75 respectively. Find out (i) EPS,
(ii) % cost of capital of equity and debentures.
Solution
(i) Earnings per share
Profit after tax = Rs. 36,00,000
No. of equity shares = Rs. 20,00,000
EPS = Profit after tax / No. of shares
= 36,00,000 / 20,00,000
= Rs. 1.80
(ii) Cost of debentures, kd :
(based on market value)
kd = Interest (1 – t) / Market value
= 15 (1 – 5) / 93.75
= 8%
(based on Face Value)
kd = Interest (1 – t) / Face Value
= 15 ( 1 - .5) / 100
= 7.5%
(iii) Cost of equity capital:

Anticipated external financing opportunities are:
i) Rs. 100 per debenture redeemable at par; 10 year-maturity, 13% coupon rate, 4% flotation costs, sale
price Rs. 100.
ii) Rs. 100 preference share redeemable at par; 10 year-maturity, 14% dividend rate, 5% flotation costs,
sale price Rs. 100.
iii) Equity shares: Rs. 2 per share flotation costs, sale price @ Rs. 22.
In addition, the dividend expected on the equity share at the end of the year is Rs. 2 and the earnings are
expected to increase by 7% p.a. The firm has a policy of paying all its earnings in the form of dividends.
The corporate tax rate is 50%.
Solution
In order to find out the WACC, the specific cost of capital of different sources may be calculated as
follows:
Cost to debenture:
Int, I = Rs. 13
SV = 100 – 4 = Rs. 99
RV = Rs. 100
t = .50
N = 10 year
[I + (RV – SV) / N] (1 – t)
kd =
(RV + SV) / 2
[13 + (100 – 96) / 10] (1 – .5)
=
(100 + 95) / 2
= 6.8%
Cost to Pref. Shares:
PD = Rs. 14
RV = 100
SV = 100 – 5 = Rs. 95
N = 10 years
D + (RV – SV) / N
kp =
(RV + SV) / 2
14 + (100 – 95) / N
=
(100 + 95) / 12
= 14.9%

b) The company has plans to raise a further Rs. 5 crores by way of long-term loan at 16% interest.
When this takes place the market value of the equity shares is expected to fall to Rs. 50 per
share. What will be the new weighted average cost of capital of the Company?
Solution
Cost of Debt Capital = kd = Int (1 – t)
Kd = 14 (1 – 0.5) = 7%
Cost of equity capital applying dividend growth model
ke = D1 / P0 +g
ke = 2 (1.05) / 80 + .05 = 7.63%
