Know Your Number
Your retirement number is 25 times your annual expenses. Not your income — your expenses. Track every dollar for 90 days and find your true annual spend.
Example: $60,000/year in expenses × 25 = $1,500,000 portfolio target. At 4% withdrawal, that generates $60,000/year indefinitely based on historical market data.
Most people are surprised to find they spend significantly less than they earn when they actually measure it. Cut the unnecessary expenses and your number drops with them.
Maximize Your Savings Rate
The savings rate is the single biggest variable. Someone saving 10% of income takes roughly 40 years to retire. Someone saving 50% takes about 17 years. Saving 65% takes around 10 years from a zero start.
Income growth matters, but savings rate matters more. Lifestyle inflation is the main enemy — every raise that gets absorbed into spending extends the timeline.
Invest in Low-Cost Index Funds
The evidence is clear: actively managed funds underperform index funds over long periods after fees. The math is simple — a 1% expense ratio costs you significantly more in compounding than it appears on paper.
Total market index funds with expense ratios under 0.1%, tax-advantaged accounts first (401k, Roth IRA), taxable brokerage for overflow. Keep it boring. Boring wins.
Solve the Healthcare Problem
Healthcare is the piece most early retirement plans get wrong. The gap between 40 and Medicare at 65 is 25 years. The options:
ACA marketplace coverage — income-based subsidies can make this manageable if you structure withdrawals carefully. Part-time work with benefits — many people work 10–20 hours/week at jobs they find meaningful that carry coverage. Health-sharing ministries — lower cost but not insurance; works for healthy people with an emergency fund.
Build Sequence-of-Returns Protection
A 50-year retirement has one major risk traditional retirement planning doesn't fully address: a bad market in years 1–5 can permanently damage a portfolio even if the long-term average is fine.
The solution: Keep 2–3 years of expenses in cash or short-term bonds so you're never forced to sell equities in a down market. Withdraw from bonds during downturns. Replenish when markets recover.
