Chapter 4: TVM Flashcards
compounding
process of finding the future value of a single or series of payments. it’s based on periodic interest rates unless using continuous compounding
cash flows
can be positive or negative
for a borrower, the first cash flow is positive and the rest are negative. opposite for a lender
Methods to solve TVM probs
- step by step approach- using the timeline. helps show you what’s happening but is time consuming
- formula approach- FV(n) = PV(1 +N) ^N
- financial calculator
- spreadsheets
simple vs compound interest
- Simple interest: when interest isn’t compounded – interest is earned/charged only on principal not on interest. AKA regular interest. Divide the nominal interest rate by 365 and multiply the # of days funds are borrowed to find the interest for the term borrowed. Fixed % of the principal amount that was borrowed.
- Compound interest- interest earned/charged on principal and interest. Compound accrues and is added to the accumulated interest of previous periods.
opportunity cost
rate of return you would earn on an alternative investment of similar risk if you don’t invest in the security under consideration
discounting
finding the present value
opposite of compounding
perpetuity
payments of a fixed amount that continue indefinetly
relationship between PV and IR
If interest rates rise, PV declines
if interest rates fall, PV rises
annuity
ordinary/deferred annuity
annuity due
- series of payments of a fixed amount for a specific # of periods
- annuity with a fixed # of equal payments happening at the END of each period (mortgages, student loans, car loans, etc)
- annuity with payments happening at the BEGINNING of each period (rent, life insurance)
Why should you rather receive an annuity due for $10,000 per year for 10 years than an otherwise similar ordinary annuity?
Because each payment occurs one period earlier with an annuity due, the payments will all earn interest for one additional year. Therefore, the FV of an annuity due will be greater than that of a similar ordinary annuity.
uneven cash flow streams/irregular cash flow streams
cash flows that differ from year to year
-important classes: 1) those where the cash flow stream consists of a series of annuity payments plus an additional final lump sum in year N (ex: bonds) and 2) all other uneven streams (stocks, capital investments)
annual compounding
semiannual compounding
- when interest is compounded once a year
- when interest is compounded twice a year
note: most bonds pay interest semiannually, most stocks pay dividends quarterly, most mortgages/student loans/auto loans involve monthly payments and most money fund accounts pay interest daily.
types of interest rates
- nominal annual rates - I (nom)
- Periodic rates - I(per)
- Effective annual rates - EAR or EFF%
- Annual % rates - APR rates
nominal annual interest rate
rate quoted by banks, brokers, and other financial institutions. must include the number of compounding periods per year.
For ex: a bank might offer you a CD at 6% compounded daily, while a credit union might offer 6.1% compounded monthly.
NEVER PUT IN A CALC UNLESS IT COMPOUNDS ONLY ONCE A YEAR
periodic rate
rate charged by a lender or paid by a borrower each period. It can be a rate per year, semiannually, per quarter, per month, per day, or per any other time interval.
For example: a bank might charge 1.5% per month on its credit card loans, or a finance company might charge 3%
- rate showed on time lines and used in calculations
