I'm working through the Excel sheets to better understand how each cell is calculated. I can track most of them back towards what I input or can rationally impute. I believe that Total Income must equal Total Spending. Retirement Account Withdrawals should then should be Total Income less any income sources (i.e. Non-Asset Income, etc.). However, this calculation does not match what is in the report.

Can someone explain how Retirement Account Withdrawals ARE calculated?
