Fwiw, my calcs indicated deferring SS until 70 would pay off if I made it past 80. Will I ? No say , my Dad was gone at 69 and my Mom lived to a week shy of 94. It wasn't a straight cash on cash calculation, I assumed SS income would be invested at 5% ror. I also assumed I would pay taxes on it so if SS income becomes untaxed income that will have an impact favoring taking it earlier.
Something else I considered is I may want to do some sort of compensated work between now and 70 and the SS rules effectively reduce your flexibility to do so.
Another consideration, even if I don't make it to 80 deferring SS will increase my wife's SS income . She'll likely outlive me as she's 3-1/2 yrs younger and women generally live longer as well.
I didn't plan for and won't ever depend on SS income but I am damned sure going to take it
