3. The Future Value and Present Value of a Single Cash Flow
d. solve time value of money problems for different frequencies of compounding;
What is the formula to derive the future value of an investment? \(FV_N = PV * (1 + r)^N\) - FV = future value at time N - PV = present value - r = interest rate per period - N = number of years
What is compounding? Compounding is when interest earned is reinvested into the original value so that the next period of interest is applied against a higher value.
What is the formula to derive the present value of some future amount of money? \(PV = \frac{FV_N}{(1 + r)^N}\)
What is a discount rate? The discount rate is just the interest rate used in a present value calculation.
How do you use the BA II Plus Calculator to compute Future/Present Value?
- N = number of periods
- I/Y = Interest rate (10 = 10%, not 0.10)
- PV = Present Value
- FV = Future Value
- To calculate, just enter in the known params, hit CPT
and the param you want to compute. E.g. 5 N, 10 I/Y, 100 PV, CPT FV
= 161.051
What is the future value calculation for rates that compound more than once per year? \(FV = PV \times (1 + \frac{r_s}{m})^(m \times N)\)
What is the future value calculation for an interest rate that is compounded continuously? \(FV = PV \times e^(r_s*N)\) - N is YEARS, not months. So for 18 months, N=1.5
When using the BA II Plus Calculator TVM functions, should the future value (FV) be entered as a positive or a negative? Enter it as a negative, it is seen as a payout.
