KissFC Financial Calculator - Version 1.5.2 What's the use of another Financial Calculator? The only possible answer is: Try this one. If you know and appreciate the K.I.S.S. concept (Keep it simple, stupid!), then you'll probably like this program. It's not a competitor for the heavy weight financial programs. But for the simple financial analysis it performs, it does it better and faster than any other program I've ever seen.
