Is this how FIRECalc calculate the 30 year cycles?
This is a naive question. I am just wondering how FIRECalc takes into account for each 30 year cycles.
Say I choose 30 year cycle and FIRECalc starts with year 1871. So, it assumes that I begin with my portfolio value from each cycle begin year, and compares with say, S&P500 year end value for the following 30 years.
Below is what I assume what it does:
Cycle 1: compare from 1871 to 1901
Cycle 2: compare from 1872 to 1902
Cycle 3: compare from 1873 to 1903
Cycle 109: compare from 1979 to 2009
Is this how it is done?
