COST OF CAPITAL
WEIGHTED AVG COST OF CAPITAL (WACC)
r = wdrd + were
wd = proportion of assets funded by debt
rd = After-tax cost of debt
we = proportion of assets funded by equity
re = cost of equity
2
COST OF CAPITAL
rd = 10% rp = 15% re = 18%
wd = 40% wp = 10% we = 50%
Proof: Firm raises $100 -- Buys an Asset
Asset earns $14.50:
Debt: $40 @ 10% = $ 4.00
Prefs: $10 @ 15% = $ 1.50
Equity: $50 @ 18% = $ 9.00
Total $14.50
WACC = 40(.10)+10(.15)+50(.18)= 4 + 1.50 + 9= 14.50%

COST OF CAPITAL
ESTIMATING COSTS
DEBT: BANK RATE
YIELD TO MATURITY ON BONDS
Find the IRR on the bond: PV=Price
FV = 1000
Payment = Coupon/2
N = #years * 2
Return you get (irr) is a six month return
Yield to maturity = rd = 2*irr
Note: Strictly, rd = (1+irr)2 - 1

COST OF EQUITY
Constant Growth Model:
re = DY + CGY
DY = Dividend Yield
CGY = Capital gains Yield (Growth)
Capital Asset Pricing Model
re = rf + (Mkt Premium)
rf = Risk Free Rate
= Relative Riskiness of Firm
Mkt Prem =Risk Premium Paid on Average Company
= rmkt - rf

Kellogg’s Costs
Debt: Bank Rate: 8.0%
rd = 8.0 * (1-0.34) = 5.28%
Equity: CGM: re = DY + CGY
= 0.90(1.08)/39 + .08
= .025 + .08
= 10.5%
CAPM: re = rf + (Mkt Premium)
= 6.00 + 0.73(6)
= 6.00 + 4.38
= 10.38%

Kellogg’s WACC
BV Weights
WACC = .738*5.28 + .262*10.38
= 3.90 + 2.72
= 6.62%
MV Weights
WACC = .149*5.28 + .851*10.38
= 0.79 + 8.83
= 9.62%

EFFECTS OF LEVERAGE ON BETA
asset = unlevered = WE* equity
tgt = asset / WE;tgt
port = w11 + w22 + w33
12
Target Cap Structure: 25% Debt, 75% Equity
asset = unlevered = (E/V)* equity
= .851 * 0.73
= .621
tgt = (V/E)tgt* asset
= (1/.75) * .621
= 1.33 * .621
= .828
Example: Kelloggs
13
re = rf + (Mkt Premium)
= 6.00 + 0.83(6)
= 6.00 + 4.98
= 10.98%
WACC = .25(5.28) + .75(10.98)
= 1.32 + 8.24
= 9.56%
