Mine was \~$212k in 2025, last year. I was already in FIRE mode, not working. (I am now, but not because of this loss, but rather to maintain a visa in a foreign country. It's really not worth it, I realize.)
I was basically VOO and 25% or so in NVDA, and sold at the near bottom in February / March. I ended up recovering most of what I lost (ended the year like $40k down), but the opportunity cost if I had just held is about $212k. To me, that's not a trivial amount.
I'm still fine to not work, but it stings. And it stings even more because I had cash to last me well into 2026. I should have thought of it as a hedge against market volatility, but I didn't. At the time, I thought of it as a way to avoid realizing gains on stocks I didn't want to pay tax on yet. Dumb me.
Also, my significant other. Had about $30k parked in some abandoned 401k 12 years ago. Could have been 138k by now if they'd just reallocated it. I'm not sure what the allocation was then but there was basically zero growth.
Anyway, how much was your "tuition?"
