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 Franz, i need to do that on my calculator =/ RE: Hp 12c Simple PV - Gene - 10-30-2014 02:47 AM 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.

I was trying to follow the link that i posted but i wasnt getting the same results ( And i would guess that there is no way to calculate simple n and i , right ?! Thanks a lot for the help guys! D
