Thanks for sharking DaveR!
Does anyone else feel that these types of calculations fall short for Mustachians? We made the very conscious choice to live somewhere doing something that would give us an extremely high income compared to what we knew for the sole purpose of ER. Now unlike many of our peers, we have not fallen victim to lifestyle creep, and have continued to save like we were students.
When calculations have me apply our current 'earnings' to our future needs, it seems silly. I have not become accustomed to living off anywhere near to what I make, nor do I plan to in retirement.
Say for example, you earn $200,000 after tax, save $150,000 per year, and live off of $50,000, what is the point of telling me I need x percentage of that nearly $300,000 pretax number? Works for an average wage-earner, but I think many Mustachians don't fit this mold.
