We are at a net worth of 1.9M-ish ( liquid investments at 1.6M, 1.3M are tax sheltered )....no debt. One of us also has a pension which we are not taking into account right now ( treating that as a potential 'bonus' ).
You are probably wondering why we are still working, etc.... Well, we have two almost-college-aged kids, and one of us has a "pre-existing" medical condition. Very worried about the future of the ACA, etc... Probably will keep going until we have 2M in liquid investments. However, it is becoming harder and harder to do every year ( corporate culture at my company sucks )!
By the way, for those wondering about retirement planning...Personal Capital has a very nice retirement planner under the 'advisor tool' tab. It does take inflation into account, allows quite a few variables to be changed, and runs all sorts of simulations. It then outputs a nice graph of the median (expected) and 10th percentile ( worst case ) scenarios. I'd recommend Personal Capital for this tool alone.
Edit: Forgot to add that we are also a bit worried about the super high stock market valuations these days. We have switched some of our holdings to somewhat more conservative funds ( Vanguard Wellesley - VWIAX ). Not to be a downer but I also fear that we could see a stock market correction in 2017...but then again who knows!
