GPatronas,

Why thank you very much, it just so happens that I've been ignorant on the possibility of an app for this.
My initial search has revealed the Wall Street Financial Assistant business calculator for palm OS and pocket PC, which is priced at $19.95 while the TI Calc is selling at $28.48 from Amazon. Of course the two may vary in functionality, I'm not sure, but hey, information is power.

Thanks again.
