So I was thinking about adding in the value of the pension into my net worth, because I don't currently do so.
One issue it presents though is projections.
It may be ~100k now, but that will decline in real terms. As the rest of my portfolio grows over the next few months, years, and decades, that will stay the same amount as whatever it ends up at when I FIRE. So it will be a smaller and smaller portion of my net worth, and when I finally collect the tiny pension, that 100k won't be worth much. That all makes sense.
When making projections about Net Worth, however, you generally assume it will grow at X% (or whatever your assumptions are). Only now you have 100k in there that not only won't grow at that rate, but will actually decline in real terms by whatever the inflation rate is.
So if you're doing any net worth projections, you need to back out that 100k and not count it (so why add it in the first place?) or you need to count it at its negative real return. Either is a bit odd.
In any case, it was something I thought of while noodling over the issue, figured I'd post it in case it was relevant to anyone else.
