I am looking for a program (or just a formula would do - I could write the
program) that figures out your total annual rate of return based on monies that
were invested at different times. For example:

	DATE	AMOUNT INVESTED
	----	---------------
	1/1/90	$1000.00
	2/1/90  $1000.00
	4/1/90  $2500.00

On 7/1/90 you have $5000.00. Your profit was $500.00 after 6 months on an 
investment of $4500.00, but you had $1000.00 invested for 6 months, 
$1000.00 invested for 5 months, and $2500.00 invested for 3 months. 
What is your annual rate of return on this investment? (It's not simply
22.22%.)

The program I am looking for would read a file to get the list of investments
made, and would also have a mode where you could enter new investments which 
would be written to the file. 

As I said above, if someone could provied me with a formula to calculate
such a thing, I will write the program and post it if there is interest (no
pun intended).

Thanks!
