Finance Programs for HP 48
D. Royce Stricklan
Does anyone know of a program that will give your hp48 some financial
calculation functions? specifically IRR (internal rate of return), time
value of money....
thanks

In article <3579D29F...@engr.orst.edu>,
G/GX models have a TVM command (emulating all HP financial calcs)
and a form-based TVM application (right-shift "Solve Finance");
check the User's Guide.
No built-in IRR in G/GX, but a simple IRR is part of a post:

MacDonald Phillips has written a large set of financial functions
for G/GX, which, like the above, are not available for S/SX;
refer to the newsgroup FAQ for download locations & current version.
For S/SX/G/GX, TVM on Goodies Disk #1 and BOND on GD#7 may help
(in fact, this TVM does more than does the G/GX built-in TVM);
see the following posts for further information
about each of these programs:

"Time is money"
So, if I've got "all the time in the world," how much money is that?

I've heard several people ask recently about Time Value of Money
programs. A year or so ago I wrote a program called ECON and turned
it into a library. I thought someone else might be able to use it so
I wrote an instruction file last night and zipped it up for download.
For now, you can get it at http://eng.utoledo.edu/~bgarrets/econ.zip
I uploaded to hp48.ml.org tonight so hopefully you can get it there
soon too.
It basically eliminates the use of tables in the back of most economy
books. I took an engineering economy class once which involved the
use of the lookup tables quite a bit. My program, ECON, uses the
formulas to find the values in those tables. It accepts usually two
arguments: the interest rate and the number of periods.
If you have a use for it, download it and use it all you want. If you
don't have an econ book handy, some of the functions may be a bit of a
mystery. :)
