Just thought id throw this out here. Got tired of keeping up with all the math in my head so done up a easy way to find my numbers i need. I know there have been other spreadsheets but just thought i just add to them. Easy to follow just add what you know to the red sections and the rest is done for you. My big thing was coming up with PE numbers to get me where i want so i came up with this to help me. AFR.xlsx
