Garyt,
Congratulations on your savings! You guys did a great j*b!
In my mind, the biggest question is what are your current expenses and how are these projected to change when you both retire?
Your $800K can give you roughly the same income as your SS at 62. Here are some examples at various SWR ("safe" withdrawal rates), assuming roughly a 30 year retirement plan:
$ 32K/yr at 4% annual withdrawal
$ 28K/yr at 3.5% annual withdrawal (fairly conservative for 30 yrs)
$ 24K/yr at 3.0% annual withdrawal (very conservative for 30 yr horizon)
So, say $ 30K/yr withdrawn from your investments + $ 30K/yr from SS = $ 60K/yr for living. Is this enough?? Don't forget to include taxes (probably much lower than when working) and ACA health insurance & projected Out of Pocket health expenses (checking healthcare.gov, could be $ 10K+ yearly if can't manage income for substantial ACA subsidies).
Also, how close are you to 65 & Medicare? Perhaps 3-4 years from Medicare and SS at 62 yo if necessary is more encouraging than if you are 10-15 years from Medicare.
Regarding ACA, I retired 2 years ago in good part because of ACA made health insurance portable, although not necessarily inexpensive. So I'm weathering the current situation, and although ACA seems to have survived the recent political challenge, little seems to have been done about increasing premiums and out of pocket and shrinking provider choices. So it help to have some margin/headroom in your calculations.
So retiring before Medicare and without the protection of big gov or Megacorp health bennies is NOT for the weak or the dumb. It's certainly a calculated risk that needs to be weighed with care. Still, you managed to rack up $800K on a sub 6 figure salary, so you must be either very lucky or very smart and determined
Additional caveat: safe withdrawal numbers assume very low investment expenses, say 0.2% or less. All bets are off if you are paying 1%+ to financial advisor PLUS 1-3% or more for expensive actively manage funds and/or annuities.
Good luck!
