We just hit the 3M mark, but I'm including the equity in our house. Background: I'm 41, my husband is 50. We both work in tech, and live in a VHCOL. Almost half of that 3M is in our 401Ks. The rest is split between liquid investments & home equity. My plan is to start spending down the liquid (if needed), as I'll be quitting my high paying job in June. I think our net worth will stay roughly the same, as our investments will grow, and my husband is hitting the sweet spot of his stock vesting schedule.
From a timing perspective, our net worth grew as follows (and, using the numbers I have available on my tracking chart - not because they are particularly round). The large increases are mostly due to stock vests.
-1/11 - $790K
-2/13 - $1,025,000
-10/14 - $1,514,000
-5/15 - $2,056,000
-11/16 - $2,381,000
-12/17 - $3,098,000
