Parameters for Inflation and Portfolio Return

[JoelAlbert]

All,

Like others I really love using this tool and am very great full for the insights it provides.

However, I am really struggling with what reasonable numbers are for some key values giventoday's climate.

For instance

Inflation Rate % and Std Deviation
- I have been using 2.5% with a deviation of 3%

Portfolio Return $ and Std Deviation
- I have been using 4% with a deviation of 12%

What I don't know is -- are these reasonable numbers? Anyone have better ideas?

Thanks

Joel
