I have the normal finance app that comes with the calculator but I need to do stuff like IRR and NPV of deposits with varying values. I tried getting the manual for the thing but it decided to be 7.8MB and crashed FF many times while trying to open it.

Dose anyone know of a "full featured" finance application for this calculator?

for finance, ti 83 is the best thing to get. it can do irr, npv, uneven cash flows....ti 89....not that easy to do it.

I know you can do iir(.... but I keep getting too many arguments errors and its frustrating as hell. I was trying to find an app that would do it but I cant find any. I dont know how to make programs on this calc either. On my 83 I could do simple stuff (every physics equation through mechanics 1)

just pull out the 83 then. the 89 is usless for all business apps.

Try TIConnect. It's really finicky with USB especially on Vista. It took me 3 hours to figure out how to get files from my computer onto a TI-89. I was getting some finance and stats stuff. Finance test tomorrow with everything the OP mentioned on it.

Check out this website, and you may be able to find some handy apps.
