I am working on time worth of money problems and my calculator keeps offering me a totally wrong answer till I recollection the calculator, by pushing the reset switch at the earlier. For instance, once calculating N=5; I/Y=8; PMT=70; FV= 1000; CPT PV= -960 I will certainly not obtain the correct answer of 960 every time. Sometimes it offers answers that are means off, which causes me to reset the calculator and also then I gain the best answer. I will certainly then occupational on a pair more troubles and also my calculator will offer me the wrong answers aacquire till I reset it. Does anyone recognize what might be causing this? I simply obtained this calculator about a month back.

I won’t be able to tell your trouble till I acquired to view what you are doing exaclty yet I have the right to assume those are the adhering to mistakes: 1) You are transforming the mode to start mode - if your calculator is reflecting “BEG” on head of the display, click on 2nd PMT second ENTER second CPT, it will go the end mode. It should provide you right answer 2) Make sure that the signs of PMT and also FV is comparable and various to the PV - don’t enter (+) for FV and also (-) for PMT 3) I/Y is given in integers not in decimals I can’t think of other possible mistakes at the minute … Omar


Hey, thanks for the response but I am not making any type of of those mistakes (I checked very carefully) I simply did the adhering to question: N=3; I/Y= 10; PMT= -100; CPT --> PV = 248.69 When I simply did this question, I obtained 502.63 When I recollection the calculator I then acquired the correct answer of 248.69 and also I didn’t enter anything any in different ways. This is bring about me to need to reset the calculator nearly every question…so frustrating!


Okay, I simply determined the difficulty. I wasn’t pushing <2nd> after each problem so it was conserving my previous history and also that was causing me to get the wrong answers (therefore why reestablishing the calculator worked). Is there a way that I have the right to change the settings so it immediately clears? Or execute we constantly need to perform it manually after each problem?


yup <2nd> resolved it for me too.additionally 2ND CLR WORK is additionally supplied in some various other instances i cannot remember wbelow though.

yes you have to clear it - what I execute actually is that I clear it twice just to confirm - acquire to this habit its really beneficial OR you will certainly need to enter all information … for example, in this set: “N=3; I/Y= 10; PMT= -100; CPT --> PV = 248.69,” you will certainly need to enter FV of zero to gain exact answer if you dont desire desire to clear Omar

I always just make certain I’m entering all 5 variables, tright here will certainly be cases wright here you’ll have to enter a calculated worth for FV or PV and also just readjust the periods or payment.

Thats what I execute as well however I additionally clear if the difficulty I’m functioning via is over - just to be safe


Hi Omar

I have very same difficulty through my BA II Plus pro.

For time worths it provides me a complete wrong answer.

FV 1000

I/Y 10

N 5

CPT PV= 620.92

But my calculator offers me 886.2763

The BGN mode is off. I tried so many kind of examples and also the same thing…

can it be the calculator?

Please help


1000/(1.1^5) = 620.92 present value of a single payment of 1,000 to be received 5 years from now at 10% interemainder compounded annually

To do the over, P/Y=C/Y=1, PMT=0, N=5, I/Y=10, FV=1000, CPT PV 620.92

Have you ensured your settings for P/Y, C/Y, and also PMT are correct?

All I can guess is you’re not clearing your TVM inputs prior to inplacing the above, and you have actually a number that is not 0 in the PMT input. Solving for PMT based on your inputs and PV result, it looks choose you have 70 conserved in your PMT input, where it would should be 0 to gain the correct PV answer.

You have the right to hit RCL then any kind of of the TVM keys to tell you what input is saved tright here. Pressing 2ND then FV will certainly clear your TVM inputs.


Hi, while resolving TVM difficulties as soon as I set input for N same is reflected through I/ Y and also vice versa …have tried via reset of calculator still the exact same issue…plz help…
