Rollforward of Regular Assets / Retirement Accounts from Year "0"
This situation applies to both subject matters, but I'll just give specific examples using "Retirement Accounts" tab in the spreadsheet output by the program.
One expects the end of year balance to equal the beginning of year balance, plus income, plus contributions, less withdrawals. This works for all years for which all the data is presented, but does not appear to work for Year 1 (beginning balances, as entered manually into the program, are not shown).
In other words, if I take the Retirement Account ("RA") balances I enter into the program, add RA income, add RA contributions, and subtract RA withdrawals, I do not get the RA Assets balance shown.
The same thing applies, as mentioned, to Regular Assets.
While the difference is small (in terms of it's potential impact on annual consumption calculations), it is highly problematic as I track progress during the year against my "goal", the "goal" being the year end balances as provided by the program. In that regard, the unexplained difference is substantial in terms of my overall activity in Year 1.
