Retiring at 65 on $72K: The 28-Year-Old Scenario

At 28 with annual expenses of $72,000, you need your portfolio to sustain 20 years of inflation-adjusted withdrawals. By age 65, inflation alone will push your spending to $214,936/year.

The Power Law model says this plan works. Your portfolio reaches $25.9M at retirement, and your maximum sustainable spending is $620,754/year — 8.6× your target. That gives you significant margin for unexpected costs.

The critical variable here is expenses, not age. A 28-year-old spending $52K/year reaches retirement with significantly more than someone spending $72K. Meanwhile, the same $72K 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 $5.1M by age 65. The CAGR 20% model projects $36.9M.

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