Chapter 6 Flashcards
What does the I/YR button on the calculator mean?
Interest rate per year
What does the N key on the calculator mean?
Number of periods
What does the PV button on the calculator mean?
Present value
What does the FV button on the calculator mean?
Future value
Calculate FV of a single sum
Ex. 30k lump sum to invest today. Compound annual interest of 6%. What will the FV be in 5 years?
[SHIFT] C ALL
$30000 +/- PV (enters the PV. should be negative)
6 I/YR (interest rate)
5 N (number of years)
FV (shows solution) $40,147
Or
FV = PV * (1 + i)^n
Or
PV * FV factor
How is the effective interest calculated?
Nominal interest rate of 6
12 payments per year
[SHIFT] DISP 4 (4 decimals)
6 [SHIFT] NOM % (enters nominal rate)
12 [SHIFT] P/YR (sets 12 payments)
SHIFT EFF % (determines effective interest rate)

Ordinary
Future value of annuity calculation:
Phil will deposit $1k, annually, for 4 years. First deposit will be made in one year.
If 5% compound interest, how much will be in account in 4 years?
1) Clear calculator
2) [SHIFT] BEG/END (if BEGIN is displayed)
3) 1000 +/- PMT (-$1k as payment)
4) 5 I/YR (int rate)
5) 4 N (4 years)
6) FV (solves $4310)

1) Make sure doesn’t display BEGIN
2) 5000 PMT
3) 5 I/YR
4) 10 N
5) PV ($38608)
Payment required (Phil needs to have $10,000,000 in 4 years to buy a mansion. He will make 4 annual deposits at the end of the year at 8% annual interest. How much do the deposits need to be?
1) Clear
2) make sure not set to BEG

4) 8 I/YR
5) 4 N
6) PMT (2,219,208)
