With a 20‑year horizon, high savings, and \~$1.38M already invested, you’re in a strong spot overall. At this point the big levers are your total stock/bond mix, how much international you really want, and how big that cash/T‑bill buffer needs to be given your spend and bonus swings. On the 401k overlap, I’d think at the household level first: if you’re fine treating your core equity as “one big total‑market fund,” there isn’t much benefit to layering an S&P index fund on top of FXIAX in the same plan. Swapping that Freedom 2055 slice for a single international index or small‑cap fund is a reasonable way to add diversification, but I’d keep it to one extra sleeve so the 401k doesn’t turn into a mini fund zoo. On international, when I test a mostly‑US mix versus a version with \~20% VXUS in a portfolio analyzer, the risk profile looks very similar and the international piece mainly spreads your equity exposure across more economies and sectors instead of acting like a magic return boost. For a 20‑year plan, something roughly in the 15–25% of stocks in international range is common; it’s really about your comfort with US‑specific risk vs global diversification. On cash, \~18 months of expenses in near‑cash is on the high side but not insane at your spend level if it helps you sleep and gives you flexibility around jobs and big expenses. The trade‑off is that every extra month you hold in cash is money not compounding, so I’d pick a clear target (say 12–18 months for true emergencies and career flexibility) and treat anything above that as part of the long‑term portfolio you’re deliberately investing. You’re already doing most of the tax‑efficiency stuff right (maxing 401ks, backdoor Roths, HSA, broad equity in taxable, not prepaying a cheap 2.7% mortgage). As your spouse gets closer to 50, it’s mainly about using catch‑up room and thinking through bond placement and eventual withdrawal order. The way I manage a similar setup is to treat everything as one household portfolio and use a portfolio tracker/analyzer to see the true stock/bond and US/international mix plus the cash buffer across all accounts, rather than checking each plan in isolation. Do you have anything today that gives you that kind of single view, or are you mostly piecing the allocation together by hand from each provider’s dashboard?
