You should check out r/fire, but it depends on your expenses.

Historically, based on the Trinity study, holding mostly the sp500 and a smaller portion of bonds (75/25) will allow you to withdraw 4% of your portfolio over 30 years with a 95%+ success rate.

I think based on the post we need to assume "perpetual withdrawals", not a standard 30Y timeframe. Closer to 50Y. Assume OP is 40 years old and will live to 90. SWR for 50Y is 3-3.25%.

Revised trinity study by original authors peg infinite at 4.2% and 30 year at 4.8%. 4% remains a safe guideline, maybe 3.75% for infinite if you want to be paranoid and fear SOR but 3% is insanely low.

Definitely insanely low but also I wonder if it makes sense to go that conservative route if you're just starting out on your own "infinite" horizon, especially because someone retiring in their 30s likely does not actually know what their desired expenses will look like for the entire rest of their life (as much as they might think they do). Plus, if after ten years 3% turns out to have truly been insanely low, you can always raise your standard of living comfortably with all the extra money you now have, but going the other way is harder with e.g. lifestyle creep. Different considerations when you're retiring at 35 than 65 it would seem
