4% rule doesn't work in Firecalc?
I'm sure we all know William Bengen and the 4.15-4.5 percent rule.
So one would expect if I put in firecalc any value (I used a million) and spending 4% of that (less than Bengen number) with a 0 expense total market portfolio of 50/50, 75/25, or even 100/0, that firecalc should confirm that Bengen was right and the portfolio should survive 30 years.
Instead, I consistently get a a handful of failures and a lot of almost.
So where is the gap?
