Retiring at 65 on $120K: The 28-Year-Old Scenario

At 28 with annual expenses of $120,000, you need your portfolio to sustain 20 years of inflation-adjusted withdrawals. By age 65, inflation alone will push your spending to $358,227/year.

The Power Law model says this plan works. Your portfolio reaches $25.7M at retirement, and your maximum sustainable spending is $620,754/year — 5.2× your target. That gives you significant margin for unexpected costs.

The critical variable here is expenses, not age. A 28-year-old spending $100K/year reaches retirement with significantly more than someone spending $120K. Meanwhile, the same $120K lifestyle starting 5 years later means fewer years of compounding and a smaller nest egg.

A traditional 60/40 portfolio with the same savings would reach only $4.9M by age 65. The CAGR 20% model projects $36.7M.

This is not financial advice. Bitcoin is volatile and past performance does not guarantee future results.
