A comprehensive view of your financial footprint at ages 39 and 38.
With ~$2.24M in liquid diversified investments (Brokerage, 401k, IRAs, 457) and aggressive maximum contributions (Pre/Post tax 401k), you are effectively already "Coast FI". Even if you stopped contributing entirely today, at a conservative 7% real return, your retirement accounts alone would double every 10 years, reaching over $9M by age 60.
Your daughter is 4 years old. The 529 currently sits at $43k, and you contribute $500/mo ($6,000/yr). Assuming a 7% average return over the next 14 years, the account will grow to roughly $250,000 by the time she turns 18. This is highly optimal and should comfortably cover 4 years at most public or private universities.
