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/cgisys/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

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.

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 builtin 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.

That's simple interest. And i would guess that there is no way to calculate simple n and i , right ?! Thanks a lot for the help guys! D
