- Start to take at 67.
- Assuming $72000 balance by 70
If you put the $72000 in a broader market index fund, assuming only 8% annual return, you can withdraw $599 per month until 90 (by then the initial $72000 drops to 0). That's exactly the $600 the government promises for delaying to 70. (but the government doesn't promise how long one would live - in exceedlingly majority of cases, it's a better deal for the government if you delay to 70)
If the index returns 10% instead of 8%, you can take out $1764 per month for 20 years (till age of 90) - much more than $600!!
(8% isn't unthinkable. S&P index returns >9% last 30 years).
67 is a much better deal, because you have the money in full control regardless how long you live.
