retirement calculator

["cwest" <cwest@xxxxxxxxxxxx>]

Has anyone come across a complex or advanced retirement income calculator
that deal with these variables: 

	current investable amount
	available to invest next year
	years to retirement
	annual percentage increase in new money to invest each year
	anticipated annual return on invested money
	percent of future value spent each year when retired
	life expectancy (after retirement)
	inheritable amount.


Thanks in advance
