It's possible to build a spreadsheet in Excel to do all the future value calculations you're looking for. It takes a bit of poking around to find the appropriate functions, but it may occupy your time on an overnight if you're so inclined.

The other thing a I've found pretty valuable is an app for my iPhone that simulates an HP 19B business calculator. This is the calculator I used in undergrad as a business major in the late 80's. I think the app is somewhere around $5 and does all kinds of future value calculations. It's a bit bittersweet for me to own the app for $5 because the actual calculator cost $200+ in 1989 dollars.

The app is sold by RLM tools dot com. If you search for "HP 19B calculator" on the App Store, you'll find it listed as RLM-19BX.
