Hp 12c Simple PV
Hey guys i have been trying to calculate a simple PV and it just doesn't work ! i found this post here but for some reason my results are different, ay idea ?

http://www.hpmuseum.org/cgi-sys/cgiwrap/...ead=131585


FV=1.500
N=1.5
i=6%
pv= ? should be 1,376.15 But im getting 1,373.88

Thanks =D

RE: Hp 12c Simple PV
Define "should be" :-)

Excel gives $1,374.46 to =PV(0.06,1.5,0,1500)

That's what the 10bII+, 17bII+, and the 12c in "C" mode (press STO EEX and solve this on the 12c).

So, I'm guessing this must be a TI model that has defined "should be" ? Again :-)

Partial periods require more information in order to solve them. Can you get Excel to give the 1376.15? If so, by what formula ?

That will help us know how to help. All questions are good, hence the smileys here.

Using the Formula P=s/(1+rt)

So, P=1500/(1+(0.06*1.5))
P=1,376.15

And also if you checked up the link for the other Post, they say how to do it, but i still got different numbers, even doing the same steps Sad

Franz, i need to do that on my calculator =/

RE: Hp 12c Simple PV
aha. That's simple interest.

The financial calculators use compound interest for n > 1.

For example, using P = S / ( 1 + r x t ) for t = 5 years, you would have P = 1500 / ( 1 + 0.06 x 5 ) or 1153.85.

I am not aware of any financial calculator that handles simple interest built-in for situations where n or t in this case is > 1.

Sorry! You'll have to do it by hand or write a short program.

Store S in 00, Store r in 01, Store t in 02 and then as a program:

RCL 01 RCL 02 x 1 + RCL 00 X<>Y / GTO 00

would solve the present value in a simple interest circumstance.

For simple interest you could just use the following:

n = 1
i = 9 (= 6*1.5)
FV = 1500

Pressing PV should yield the requested -1376.15.

For some reason it worked this time! I was trying to follow the link that i posted but i wasnt getting the same resultsSad(

And i would guess that there is no way to calculate simple n and i , right ?!

Thanks a lot for the help guys! Big GrinD
