### My TI BA II Plus is returning incorrect answers for TVM problems... Is this common and can it be fixed?

Let's see, 10% interest per year on \$100 for one month. That's 10/12 of a percent interest on \$100 is \$0.83, added to \$100 is \$100.83 (with a bunch more 3s at the end). Clearly this is the correct answer.

What answer are you expecting? The future value at the end of one year instead of one month?

### My BA II plus professional showing wrong answer while computing "N" during TVM calculation

Make sure you have P/Y set to 1 and BGN/END set to END. With those settings, pressing 9 I/Y 9 2 0 FV 1 0 0 +/- PMT CPT N should produce 7.00 .

### Calculating TVM variables I/Y & N. eg. N = 10, PV = 10,000, FV = 20,000, PMT = 0 but when I CPT I/Y I get Error 5

Error 5 indicates that no solution exists. In this particular case, you're asking for the interest rate on a savings account that pays you 10,000 now and an additional 20,000 10 years later. (Or a loan where you pay 10,000 now and an additional 20,000 10 years later.)

Either PV or FV should be negative. For example, if you deposit 10,000 in a savings account and withdraw 20,000 10 years later, use -10,000 for FV.

### Im am baffled. my ba-II plus is not calculating TVM correctly. ive tried resetting, making sure end period was selected (i.e. ordinary annuity) but no luck. as an example i enter... n=1, i=10, pv=-1,...

It's giving you the correct answer for the problem you've input. When you specified 1 for n, you told it one month. If you specify more digits, you'll see that the answer is 1.00833333.

By default, the calculator works with annual interest rates but counts periods in months.

### Computing N in a TVM calculation (receive Error 5 message)

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

### PV and FV problem, result not like in manual

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.

### Simple loan payment

Are you putting 30x12=360 for N? Since you have monthly payments, you have to compute it a little different. Also, you have to find the effective monthly interest rate. 1.0575^(1/12) = .4669839%.

Another way is to enter 30 for N and 5.57 for I/Y, and change P/Y to 12.

Hope this helps!

### Finding N value on Ba11 PLUS

You need to have your PV and your PMT be a different sign. Try making your payments negative.

### I do not have the directions and need to figure out how to calculate mortgages.

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
