When I became 70-1/2 and had to begin drawing down my 401 and IRA I tried to calculate the required minimum disbursement (RMD) myself---and found it cloaked in a mythical bureaucratic cloud of fog---I gave up and referred the calculation to my accountant.

I am trying to do planning for the remainder of the year and wanting to know the current RMD for both my wife and I and unwilling to wait for the answer from my accountant---I gave it another shot---and what do you know--- it is now a cake walk. That link is good if your spouse is less than 10 years your junior, if greater than that there is another chart.

Happy planning
