Are you sure the PV and PMT have different signs? One (and only one) of them must be negative.

SOURCE: PV FUNCTION GIVING WRONG ANSWERS

The BAII Plus comes from the factory set to assume monthly compounding. To fix this problem press 2nd then I/Y and enter 1 when prompted.

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.

SOURCE: how can i tell the difference b/w hp12c and hp12p.

I couldn't find any reference to a HP calculator model 12p.
There is a HP 12c financial calculator and a 12c Platinum financial calculator.
Check both models (for images, specifications, functions, user guides, etc.) :

SOURCE: haveing trouble getting the IRR using the BA II

I get 6.085%. Make sure the fv and pmt are of opposite signs. You're either making annual payments and getting a lump sum back at the end, or receiving annual payments and then paying it all back in a lump at the end. Either way, the money is moving in opposite directions.

What is CPT on TI Calculator


"ComPuTe". On TI financial calculators you have to press the CPT button before pressing the button for the value you're solving for. (N, I, PV, PMT, or FV). On an HP calculator, you just press the N-I-PV-PMT-FV button without making any entry in order to solve for the desired value.

Error 1 or error 5 while solving for TVM problems.


According to the manual, error 1 indicates "Overflow", a number whose magnitude is greater than 9.9999999999999E99. Error 5 indicates "No solution exists", for example when FV, (N*PMT), and PV all have the same sign.

If you still have trouble, please feel free to reply to this post, giving sample problems producing these errors.

I simply can not get the BA 11 plus to run a simple TVM calculation. Although I have the card, and feel that I am following the instructions properly, I always get error 5 code. What am I doing wrong?...


Error 5 indicates one of two conditions while doing a TVM calculation.

1) You tried to compute the interest rate when FV, PV, and PMT all have the same sign. Make sure cash inflows are positive and outflows are negative.

2) The LN input is not greater than zero during calculations.

The first is much more likely.

Tvm_I%


I'm going to make up an example so this is easier to answer.

Ex: You have a bond with a price of $987, with a coupon of 1.5%, which matures in 10 years.
To do this problem:

[APPS] [1] [1]

What comes up on screen:

N=
I%=
PV=
PMT=
FV=
This is all the stuff that you really care about.

Now, add in the info you know from the equation. Put in a 0 if you don't know the number for that part.

This is what it should look like:
N=10
I%=0
PV=-987
PMT=15
FV=1000

Now, cursor back up to the I%=0 part.
Highlight the '0' that you had in there from before.
[ALPHA] [ENTER] ----> notice above the enter button it says in green lettering "solve", this is what you are trying to do.

Yay! Your caluculator has now figured out the interest rate!
it should say:
I%=1.642027191



Notes:
1. Make sure your payment is set at the end of the period (this is just the standard so you probably don't want to mess with it.) Scroll down to the PMT: END BEGIN part and make sure the END is highlighted.

2. This example used annual coupon payments. The p/y and c/y business is used for when you have semi-annual payments or semi-annual compounding (or daily, or hourly etc). You can use this feature, or you can just adjust the payment and periods
(ie: if this were a semi-annual coupon bond, the N would be 20 and the pmt would be 7.5)

Mortgage payment


what numbers are you putting in? For example, I just plugged in
N=360 (12m/30y)
I/Y = .5833 (7/12m)
PV = 200000
FV = 0 (it will be paid off)
PMT = 1,330.6050
The only thing I could offer is that perhaps you forgot to enter one of the variables...?
