Calculate present worth

[Juzme]

Will somebody please point me to freeware that will calculate and display
the discounted present worth or value of any income stream to be received
for a given number of months or years during which interest rates will be
at various chosen levels -- something like a set of automated present worth
tables. Alternatively, a table of factors to apply in my spreadsheet would
work with a bit more input. I'll very much appreciate it, juzme

Most spreadsheets have financial functions. Try open office.

As you suggested I took my first long look at OOo's spreadsheet and sure
enough, under "help/present worth/calculate" I found exactly what I need.
I'm going to further explore this wonderful software.
Thanks, cactus.
