TVM function on calculator not working properly

CFA General
#1

Hi guys, I’m new to the forum. My calculator (TI BA Plus2) is playing up with its TVM function and I’m wondering if it is a settings issue or if I have just forgotten some basic thing of how to use it from level 1 and 2. I changed the battery, cleared tvm and cleared memory. I’m attempting a contingent immunization question and entered the following: PV = 93,000,000 N=6 I/Y=4.25% PMT=0 when I then CPT FV, I get -94,993,830.9 This is obviously wrong, the answer should be 93m*(1.0425)^6=119,382,132 Can anyone spot what is going wrong? Thanks

Clear your TVM and WRK memories… CLR TVM and CLR WORK

#3

Thanks, but as mentioned in my post I cleared both before doing the calc. Also, I checked whether the calc is in ‘end mode’ and it is

likely user error… like those IT guys say, the problem likely lies between the keyboard and the chair…

I forget how to use all that stuff, try looking up a manual online. Edit: Or an even better solution, try posting on the CFA Level I or CFA Level II forum on the top of the page here. Those guys’ll know it inside and out.

Check your settings on P/Y and C/Y: they should both be 1. You will then get the correct answer.

Your P/Y is set to 12 not 1. Hit 2nd then I/Y then 1 then Enter.
