While it's a bit of a learning curve if you're used to a traditional financial calculator, this program is a heck of a lot easier to use once you figure out its ins and outs.

Does a fantastic job on numerous complex financial equations. Ideal for anyone who's into finances or who just wants a better handle on their personal finances. Also an excellent tool for exploring pro-forma returns.

Great for business people, financial analysts or anybody who borrows, invests or loans money.

Documentation is serviceable but there's still a bit of searching to do to really figure out how it all works. If you have a basis of financial knowledge, then it's quite intuitive.
