My diversified portfolio is currently worth 360,000. 260,000 tax deferred and a recently created 100,000 taxable at Vanguard. I am retired and have been withdrawing 5% to supplement my pension. I'm in the 15% tax bracket. With the new account my withdrawal rate will be reduced to 3.7%. Does it make sense to now get my distributions from taxable account only until it expires and let tax deferred account continue to grow? I figure even if taxable account does not grow I can go a minimum of 7.5 years before it is exhausted. What if I need a large chunk of money down the road? Does it make sense to do 50/50. I do have cash reserves to last 3 years to make up for these withdrawals but I consider this to be emergency money and a possible wedding for my daughter in the future. Any ideas or comments from the distinguished community would be appreciated.
