Formulae Flashcards
Payback definition and decision rule
Time taken for cash inflows to equal cash outflows
Accept if payback < target
ARR formula (initial investment)
(Average annual profit from investment ÷ initial investment) × 100
Profit = after depreciation
ARR formula (average investment)
(Average annual profit from investment ÷ average investment) × 100
Average investment = (initial outlay + scrap value) ÷ 2
Profit = after depreciation
ARR decision rule
Accept if ARR > target
NPV definition and decision rule
Change in wealth of investor as a result of investing in project
Accept if NPV is positive (usually)
IRR definition and decision rule
Cost of capital at which NPV = 0
Accept if IRR % > cost of capital (usually)
IRR formula
a + (NPVa ÷ (NPVa - NPVb)) × (b - a)
a = lower discount rate giving NPVa b = higher discount rate giving NPVb
Discount formula
(1 + r) ^-n
r = cost of capital n = years
Fisher equation
(1 + m) = (1 + r) × (1 + i)
m = money (nominal) rate r = real (effective) rate i = general inflation rate
EAC formula and decision rule
NPV of one cycle replacement ÷ cumulative DF for cycle length
Lowest EAC
Sensitivity formula
(NPV of project ÷ PV of cash flows subject to uncertainty) × 100%
CAPM formula (given in exam)
rj = rf + βj (rm - rf)
rj = expected return for security j rf = risk-free rate βj = beta of security j rm = expected return on the market portfolio
When applied to shares rj = cost of equity capital (ke)
Alpha value current return formula
Expected return ± alpha value
Interest rate parity equation
Spot rate x ((1+if) ÷ (1+iuk)) = forward rate
if = overseas interest rate iuk = domestic interest rate
Dividend payout ratio formula
Dividend ÷ earnings after tax and pref divs
Ex-rights price formulas
(Market value of shares pre-issue + rights proceeds + project NPV) ÷ number of shares ex-rights
PV of new total dividends ÷ number of shares ex-rights
If NPV not given, assume nil
Dividend yield formula
(Dividend per share ÷ market price per share) × 100
EPS formula
Profit distributable to ordinary shareholders ÷ number of ordinary shares issued
Price-earning (P/E) ratio formula
Market price per share ÷ EPS
Total shareholder return formula
Dividend yield + capital gain
Annual interest on loan stock formula
Coupon rate × nominal value
2 capital gearing formulas
Debt ÷ equity
Debt ÷ (debt + equity)
If book value include RE
