Ep. 367 — FI Number Adjustments

Most retirement calculators are lying to you—they base your FI number on income, not on what you actually spend. Brad and Jonathan break down why this matters and how to fix it.

If you spend $40,000 annually, you need $1 million to retire comfortably using the 4% withdrawal rule. That's your real FI number—not some inflated figure based on replacing your current salary. The hosts walk through the math, expose common calculator flaws, and explain why understanding your actual expenses (including taxes and insurance) is the foundation of any realistic retirement plan.

The discussion also covers financial advice for recent graduates: start 401(k) contributions immediately, avoid charging more on credit cards than you can pay off monthly, and resist lifestyle inflation. A high savings rate from the beginning compounds over decades, making early career choices disproportionately powerful.

Key Takeaways

• Understanding Your FI Number: Your FI number is determined by your actual annual expenses. Spending $40,000 per year means aiming for a $1 million FI number.
• Starting 401(k) Contributions Early: Begin contributions with your first paycheck to maximize growth through compounding and employer matching.
• Avoid Lifestyle Inflation: Maintaining a modest lifestyle significantly increases your savings rate.
