Like others here both the GF and I have pensions. When I work up our worth I certainly include an estimate for their value. Our investments are near the $2 Mil mark (nearly a 50/50 split), and if I had to guess our pensions' worth I would put them at near $1.5 Mil. The pensions should cover 100% of our needs when I start getting mine (she has just started getting hers, I have to wait 4 more years).
She gets the subsidzed health care for life too, and both have COLAs.
I don't include my paid off house (gotta live somewhere), nor our paid off cars in our net worth, though you certainly can.
My biggest long term concern right now is taxes down the road. With all of her withdrawals going to be taxed I'm trying to get as much of my savings into Roth style products as I can without raising my current taxes too bad. Once we hit 71 and have RMDs, our yearly income (2 SSI, $70k+ pension, probably $100k+ RMDs) will be so high that taxes are going to be a major headache. Once her son is out of college (in 2 years) we're going to be converting / rolling over money to Roth every year as much as is practical (10 year window). Its a good problem to have I guess, but still, this is going to take some work to do it right.
