Here's the back-of-the-envelope calculation: Annual salary: $250K (it is much higher at FAANG). Assume 25% tax (effective, not marginal), which leaves us with $187.5K, which is about $15K per month. Assume $5000 in monthly expenses, which leaves us with $10K per month investable money. (Note: since net worth includes house and 401(k) I have not deducted mortgage or 401(k) payments). So $10K includes those items.) Now use a compound interest calculator to see what $10K per month at 8% interest (assume investment in S&P 500 and allow for some market crashes) will result in, at the end of 30 years. It is about $14 million, which would include your house and your 401(k).
