James was searching the web, when he ran across my Taxes workbook and the sheet called Required Minimum Distribution (RMD). He was looking for an Excel spreadsheet that calculated the net balance each year on tax differed accounts (IRR, 401k, etc.) after the return on investments and the withdrawals due to RMD.
Rather than starting over, I added the table below on the same RMD sheet. The table calculates the balances of your accounts, out to age of 100 (good luck). The example below is truncated and show only to the age of 84.
