A few questions....

I read in another post that an 80% success rate was probably as good as 100%, just because of outside uncontrollable factors. Other posts mention wanting 100%. Just curious what I should be targeting?

Also, when the calculator asks for portfolio, what number should I use? My retirement savings? All cash assets?

Thank you.

You should use all your investment assets. Don't include your house or any other assets which are part of your Net Worth.
As for success rates, there are varying degrees of opinion here, but personally I like the number to be at 100%.
I would state that most folks who use the calculator shoot for at least a 95% success rate.
