There are a lot of different scenarios where one is better than the other and vice versa. So far you are getting the wait until it maxes out crowd, I will give you the counter point. So just for round numbers sake lets say at 62(not sure where you heard 60) you can collect $3k a month is SSI benefits. Once again for round numbers lets just assume it is stable, although there will be cost of living raises, which of course will also be in effect if you wait too. And lets assume you get 5% on your money a year keeping it in your 401k, and thus your lump sum will be the total plus 5% accruing as you go along.
So that gives you 8 years to collect $36k plus accrued interest. That lump sum is going to be well over $300k. That is your money, to do with what you want, and to bequeath to your spouse and family if need be. Not a small amount a 1/3 of a million dollars.
Now if you wait until 70 you will of course get a much bigger check, but since you didnt touch any of the money and it accrued interest all those years, you will have to live to about 85 to hit the break even point. From that time on, you are in the pink and will be getting the higher payout for the rest of your life, or your spouse if that is how things work out…Not a bad deal if you are going to live into your 90’s, but ask yourself if those extra 1000’s of dollars are going to be changing your life in any meaningful way. Because that is the bet on waiting until it is maxed, and what is it that you actually win??
the other scenario is your turn 70, and then die soon after. At that point you have gotten nothing or near nothing back of what you paid in all those years. Your 1/3 of a million dollars you would have had, never materializes and just goes poof. So nothing to leave to your wife or kids in the form of a nest egg, although the survivor benefit will be lager and the bet of a long life comes back into play for her if she is still around.
I look at is as a sort of life insurance policy that you cash in, have the money up front, and it is a tangible asset. I think for most at 85, getting a little more money every month doesnt do much, as you are likely out of the travel around the world mode and doing small things at home that dont cost much. Of course this is all individual, and peoples lives are different, but if you look around, what are 85 year olds doing where they need more money than they have been living up until then.
So for me it is basically that bet, and if you take it early it takes a long time to lose on it, and those winnings are not as important at 85 as they are at 62. If you die in your early 70;s, then you really crapped out, much worse than what you lose after 85 on onwards…
Just another look, good luck with whatever you choose…
