Uhhh... no, the ending portfolio balance is expressed in terms of the dollars as of the beginning of the retirement, not the end.
So in your example, the 1930 ending portfolio balance is expressed in 1901 dollars.
The reason for this is simply that the only thing meaningful to someone contemplating retirement is the current spending power of their assets. It only makes sense to relate all future results to the information known to the retiree prior to his decision.
So, the 1901 retiree, with a crystal ball, would know that his spending ability would be unchanged through 1930, and would also know how big a party that his survivors could have at the end.
The previous version of FIRECalc gave terminal portfolio balances in unadjusted dollars. This was not very useful, because it really didn't tell someone thinking of retiring what their ending portfolio was really worth. That's why in the revision the dollars were all adjusted to the dollar value as of the time of retirement.
Again, the philosophy is to work with what is known just before retirement, and not to report values that have no meaning without adjustments.
This certainly isn't perfect, because someone retiring on 40,000 a year in 1915 is certainly living a vastly different lifestyle than someone retiring on 40,000 in 2006.
However, if the 1915 retiree would wind up with, say, 400,000 at the end, he would reasonably expect to be able to spend 10 times his normal annual spending on his departure party at that point, regardless of the inflation during the previous years. The same would be true for the 2006 retiree.
Hope this clarifies --
