What is the Formula for the Nominal* Approximate Rate of Return?*
Nominal Rate = Real + Inflation or Real = Nominal - inflation
What is the Formula for the Nominal Exact Rate of Return
This will be the one used on the exam!
Nominal Rate = (1+Real Rate) (1+ Inf) - 1 or Real Rate = [Nom Rate/(1+ inf)] -1
If asked for Real Rate of return adjust formula
What is the Formula for the After-Tax Rate of Return
After-Tax Rate of Return (ATRR) = (Pre-tax Rate of Return) (1- MTR)
What is the Formula for the Effective Annual Rate (EAR)
EAR = (1 + i/n)n - 1
What is the Formula for FV?
FV= PV x (1+i)n
What is the formula for the FV of an annuity?
(Beware of BGN or END for the timing of cashflows)
FVA = PMT x (1+i)<u>n</u>-1
i
What is the formula for PV?
PV = FV
(1+i)n
What is the formula for PVA?
(Finding an income)
PVA = PMT x 1 - (1+i)<u>-n</u>
i
What is the decision rule for IRR?
IF the IRR is greater than the cost of capital then the investment will be wealth enhancing.
Is it less? then wealth reducing.
What is the stated interest rate?
Nominal annual rate or the contractual rate (i.e. coupon)
What is the periodic rate?
Rate of interest earned over 1 compounding period (i.e. semi-annual)
What is the effective Annual Rate
Rate of return actually being earned after adjustments for compounding frequency.
What type of annuity makes payments at the end of a period?
Ordinary Annuity
What type of annuity makes payments at the beginning of a period?
An Annuity Due
(Remember the FUTURE VALUE is always ZERO for an annuity)
What are some indicator words for an Annuity Due?
- payments on your birthday
- anniversary
- at the beginning of the year
- on Jan 1
- starting today
What are some indicator words for an Ordinary Due?
- At the end of the year
- starting next month
Current Yield Stocks and Bonds
What is the Current yield (Dividend Yield) for Stocks?
Current Yield = (Dividend/Current Market Price) x 100
Current Yield Stocks and Bonds
What is the Current yield (Dividend Yield) for Bonds?
Current Yield = (Coupon in $/ Current Market Price) x 100
What is the formula for ATRR?
(After-tax real rate of return)
THIS IS THE SHORTCUT FORMULA
ATRR = [Nominal Return x (1 - MTR)] - Expected Inflation
(1 + Expected Inflation)
What is the formula for Yield to Maturity
(Market Value for Bonds)
Yield to Maturity = Coupon + (1,000 - Market Price<u>B</u>)
n
(1000 + Market PriceB) /2
If you are looking for YTM when working with bonds what are you looking for?
The market value of a bond.
Watch for annual pay
What are P-Strips and C-Strips
P-Strips - no coupons (use the PV of a lump sum formula here)
C-Strips - are the coupons
If you were an investor would you rather have the return on a common stock or income from debentures
An investor would be better to choose the common stock because of the dividend tax credit as it applies to dividend-paying stocks. The resulting tax credit will put more money in their pocket after tax
Bond Pricing
As yields rise what happens to the price of bonds?
Yields Rise
Bond Price Falls
What is the Bond Price Formula?
Bond Price = PV (Cash Flows) + PV (Maturity Value) [This last part is the clean price of a bond]
This looks like our old friend…PV of an Annuity + PV of a lump sum
What are the 3 steps to calculating the Current Market price of a bond?
- PV (Coupon PMTS)
- PV (Maturity Value)
- Add your results in steps 1 and 2 together to get your bond price
PB = PV PV (Coupon PMTS) + PV (Maturity Value)
If you want money with certainty, what type of Bond will ensure it will happen?
Choose a strip bond
