Oh that's right, I forgot that Garth was involved in all this.
I don't want to sound overly negative. I think it's totally possible to completely stop working and "retire" in the 30s, especially for people like twowheeled, and the couple in the articles, who have very high incomes. It's possible!
But from a financial security standpoint, I think one should stay below a 3% withdrawal rate because of the very long time horizon (see post #44 above). My own calculation looks like this:
Current annual spending: 38k per year
Estimated 'retired' spending: 45k per year (margin of safety)
Withdrawal rate: 3.0%
After tax capital required: 45 / 0.03 = $1.5 million
I've already gave my opinion on SWR and drawing down capital vs. living on ONLY the income your capital can generate and not touching capital, so I won't repeat that. However, I will comment on an expectation that planning for only a 'cushion' of $7k between spending($38k) and income($45k) which is only a cushion of less than 20% is a recipe for disaster.
