A= count of years

B= year

C= iRA Balance at start of year

D= yearly contribution

E= IRA Ending value

I can get the average yearly interest rate of the entire portfolio. Unfortunatly this rate includes my contributions so I believe the rate of return is artifically high. My contributions make it look like I am getting a higher rate of return than if I had not made IRA contributions. I need a way to calculate the real average yearly interest rate I made on the account minus (or taking into concideration) the money I put into it.

Thanks in advance
