Question about Texas Instruments BA-II Plus Calculator

I've just received my TI BAii Plus calculator this morning, and started to follow the instruction in the manual until I got this problem. It's about computing value in savings and computing present value (p.28 in the official manual).

This is the example 1 printed in that page: If you open the account with $5,000, how much will you have after 20 years? (with the given interest rate is 0.5% per year)

And the instruction :

20 [N] ---> N = 20

.5 [I/Y] ---> I/Y = 0.50

5000 [+/-] [PV] ---> PV = - 5,000.00

[CPT] [FV] ---> FV = 5,524.48

I did the same, and got the result : FV = 5,041.83. I didn't do anything differently from the instruction.

The 2nd example in that page is about computing present value: How much money must you deposit to have $10,000 in 20 years ? (the interest rate is still 0.5%/year)

And the instruction : 10000 [FV] ---> FV = 10,000.00

[CPT] [PV] ---> PV = -9,050.63

I followed that in my calculator, and I got PV = -9,917.03.

I tried hard reseting my calculator, but it still got the same mistake. Is that my calculator's fault ? What should I do ?

You have the payments-per-year set to 12. For this pair of problems, it needs to be set to 1.

Press 2nd [P/Y] 1 ENTER.

Did you check in the manual if the calculator is able to do Time Value of Money calculations? Well it is not able to do so. Sorry.

I have carried out the same calculation on the CASIO CFX- 9750GPLUS and I got 5524.478.

The only explanation I can think of is that you forgot to clear the worksheets before doing the calculations.**You should reset all variables to defaults**. To do so, press [2nd][RESET][ENTER].

Check the BEGIN/END setting (2nd [BGN]) and the number of payments per year (2nd [P/Y]). If these are set correctly, could you post the problem you're trying to solve, giving both your results and the expected results?

2nd [CLR TVM] (clears any previous results)

4 I/Y (4% interest rate)

1 2 0 0 +/- ($1200 monthly payment, negative because you're paying out the amount)

2 5 0 0 0 FV (desired value, positive because you'll be receiving the amount)

CPT N (compute the number of payments)

4 I/Y (4% interest rate)

1 2 0 0 +/- ($1200 monthly payment, negative because you're paying out the amount)

2 5 0 0 0 FV (desired value, positive because you'll be receiving the amount)

CPT N (compute the number of payments)

Click APPS and then ENTER for Finance and then ENTER again for the TVM Solver. There you can input the PV, PMT, i, etc.

Check to make sure you have the proper value set for payments-per-year.

Mar 27, 2009 | Texas Instruments BA-II Plus Calculator

Change the payments-per-year to 1 to get the correct answer. Press 2nd [P/Y] 1 ENTER.

To pay off a loan of $3245 at 12% annual interest, you can either make 6 monthly payments of $559.91 and pay it off in half a year or make 6 annual payments of $789.27 and pay it off in six years.

Hey,

Just found out the answer!

Apparently you can't have both FV and PV positive. Try the calculation with one of them being negative.

Here is the link to a guide;

http://www.buec.udel.edu/bowersh/finc311_F04/Documents_f04/Quick%20Guide.pdf

Set PV=-$100,000

[2nd] P/Y= 12.00

N= 12 x 30 = 360, (i assume it's 30 Y amortization)

I/Y = 5.75%

FV = 0

[CPT] PMT

Hope this helps

Oh, I got it ! The default P/Y is 12 while it must be 1 in those 2 examples. Texas Instrument should make an adjustment here in their next edition.
