37 year old (married, no kids)
House Value: $1,600,000 (conservatively). We owe $430K at 2% interest rate on 15 year mortgage with 13 years remaining. We are not going to pay that off early given the low rate. So call it roughly $1,150,000 in equity.
Retirement Accounts: $1,400,000 (about $800K of that is in Roth accounts); Note that this is roughly an even split of $700K each for my wife and me. Investments split 60% in VTI, 20% in VXUS and 20% in BND.
Investment Account: $750,000 (60% in VTI, 20% in VXUS, 20% in VWITX)
Checking: We keep $20K in our checking account. Both of our paychecks go into this account, and we move whatever amount above $20K at end of month into investment account.
How did we get to where we are today? Put simply, a lot of hard work. Top undergrad, top MBAs, IB/PE/Consulting jobs working 80+ hours per week before moving into VP+ positions in corporate world. Also, passive investing in broad market index funds with very low fees. Home has appreciated about $600K (conservatively) since we purchased it. We max out our retirement accounts every year. We don't buy fancy watches, clothes or expensive dinners, but we do splurge on nice vacations (probably spend about $20K on vacations each year). I'm sure that not having kids has probably helped us reach the numbers above too. That decision wasn't about money... just a personal choice in that we didn't really want kids. Lastly, the money is shared and all goes into one joint account... we don't keep separate accounts (except for retirement accounts where required) based on who makes more / less (although recently we are both at similar income levels).
If I had one piece of advice it would be to put as much into your retirement accounts in your 20s as possible. Second would be to invest in passive index funds with low fees, and don't chase individual stocks (google Boglehead if you want to learn more on that style of investing).
