I am functioning on time worth of money problems and also my calculator keeps providing me a fully wrong answer until I reset the calculator, by pushing the reset button at the earlier. For instance, when calculating N=5; I/Y=8; PMT=70; FV= 1000; CPT PV= -960 I will not obtain the correct answer of 960 eexceptionally time. Sometimes it offers answers that are way off, which reasons me to reset the calculator and also then I obtain the best answer. I will then work on a couple even more troubles and my calculator will give me the wrong answers again till I reset it. Does anyone know what can be resulting in this? I just acquired this calculator about a month back.

I won’t have the ability to tell your difficulty till I gained to view what you are doing exaclty but I can assume those are the following mistakes: 1) You are transforming the mode to start mode - if your calculator is showing “BEG” on head of the display, click on 2nd PMT second ENTER second CPT, it will certainly go the end mode. It must provide you appropriate answer 2) Make sure that the indications of PMT and also FV is similar 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 feasible mistakes at the moment … Omar


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


Okay, I just established the problem. I wasn’t pressing <2nd> after each trouble so it was conserving my previous background and that was causing me to gain the wrong answers (therefore why resetting the calculator worked). Is tright here a method that I can change the settings so it instantly clears? Or execute we constantly need to carry out it manually after each problem?


yup <2nd> addressed it for me also.likewise 2ND CLR WORK is also supplied in some other cases i cannot remember wbelow though.

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

I am currently in the halittle of clearing it best after I carry out a difficulty and prior to I begin a new difficulty, just to be safe

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

Thats what I execute as well however I also clear if the trouble I’m working via is over - just to be safe


Hi Omar

I have same problem through my BA II Plus pro.

For time worths it gives me a finish wrong answer.

FV 1000

I/Y 10

N 5

CPT PV= 620.92

But my calculator provides me 886.2763

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

can it be the calculator?

Please help


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

To perform 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 PMT are correct?

All I have the right to guess is you’re not clearing your TVM inputs before inputting the over, and also you have actually a number that is not 0 in the PMT input. Solving for PMT based upon your inputs and PV result, it looks choose you have actually 70 saved in your PMT input, wbelow it would certainly must be 0 to acquire the correct PV answer.

You have the right to hit RCL then any of the TVM secrets to tell you what input is conserved tbelow. Pressing 2ND then FV will certainly clear your TVM inputs.


Hi, while resolving TVM problems when I collection input for N very same is reflected with I/ Y and vice versa …have tried via recollection of calculator still the same issue…plz help…
