To get \$500,00 four years from now, how much must you invest today, assuming an annual interest rate of 4%?

A=P(1+i)^n, where A is the amount, P is the principal or initial investment, i is the interest rate per period, and n is the number of periods.

500,000 = P (1+0.04)^4
500,000/(1.04^4) = P
P = \$427,402.10

Good luck,

Paul

Invest R10000 in a bank investing at 14% compounded twice a year.

A = P(1+i)^n, where A is the amount, P is the principal or initial investment, i is the interest rate per period, and n is the number of periods.

If the annual rate is 14%, the semi-annual rate is 7%. One year is now composed of 2 6-month periods.

So after one year, we have A = 10 000 (1.07)^2 or 11,449.

Good luck,

Paul

Hi there,

To get the coefficient of determination you need to be in STAT mode (press MODE and choose 1 for stat) and then choose 1 for line (it only works for linear data). Type in your coordinate points (type in the x value then press the button next to ENT that says (x,y) and then type in your y value and press ENT. Your screen should then say DATA SET = 1.00.
Enter a few more coordinates.
Then to get your coefficient of determination press ALPHA (the blue green button under 2nd F) and press the ( button (above it in blue you will see r). Press = and there is your coefficient of determination.

Hi there,

First make sure all previous amounts stored are cleared by pressing 2nd F MODE.
Then type in the original value 20 000 and press PV.
Type in the interest 13 and press I/Y.
(If i assume that the interest is compounded yearly my calculation is more simple)
press 5 and N

(If I assume that the interest is compounded monthly, i need to input a little bit more data into my calculator)
Press 2nd F I/Y (to get to payments per year) and press 12 and ENT. Press ON.
Then press 5 and 2nd F N and then press N again.
Now calculate FV by pressing COMP FV which should give you - 38 177.13.

Take this value and subtract the PV from it to get the amount of interest earned.

Hi there,

To calculate present value you need to type in all the other missing values and then press COMP and PV.
For example: if the future value is R5000, the interest is 12% p.a. compounded monthly and it paid over 3 years.
Type in 5000 and press FV
type in 12 and I/Y
Press 2nd F and I/Y and make sure P/Y says 12 (for 12 payments per year).
Press ON
press 3 press 2nd F N and then press N again (for 36 payments in total). Make sure your screen says ANS -> N otherwise the calculation will not work.
Now if if your payments are 0 (in other words you are not making monthly payments) then press 0 and PMT,
Otherwise, if you are making monthly payments for e.g. R200 a month, type in +/- 200 PMT.
Now calculate your original amount by pressing COMP PV.
And if you chose to add payments your original amount should be
2 526.88.

Hi there, if you are following the example from page 24 of the manual - The steps are as follows - reset or clear the previous values by pressing the orange key (2nd F) and MODE.
Then make sure that BGN is not displayed (To do this press 2nd F and FV (above it you will see BGN/END)). To set the number of payments per year press 2nd F I/Y (above it is P/Y). Type in 12 and press ENT. Press the down arrow key and to make sure C/Y also says 12 (12 compounding periods per year). Then press on. Calculate the total number of payments - to do this type in 20 2nd F N (to get xP/Y) and then store the answer in N by pressing N again. (Your screen should say ANS -> 240.00)Type in your present value 56000 and press PV to store it. Enter the monthly payment press +/- 440 PMT. Enter your future value (press 0 then FV). Now to calculate the interest rate press COMP I/Y. It should give you 7.17 %
A very common error is not pressing N to store the number of total payments into the calculator.
If this is not the example you meant, please let me know - and I will explain the other example.
good luck
