DH's pension (state pension system for municipal employees, 3% COLA) covers 115% of our living expenses. Then we have some PenFed CDs that add another 4%. It's not a huge pension and we don't have all that much in CDs, it's just that our cost of living is fairly low. That's the "guaranteed" income.
Anything extra just gets saved because stuff breaks and sh!t happens....meaning that as we get older medical expenses come up and our house needs more work.
Still coming out ahead.
We were very surprised that DH was able to retire at 55, we could live as comfortably as when he worked and still be able to save anything. We live off the pension, save the extra, and my PT income (not guaranteed) goes to savings, usually my Roth IRA or the HSA.
I'm 60 and I'll consider SS at 62. I don't want to take it until Medicare age of 65 at the soonest and most likely will wait until my FRA of 66 and 2 months.
