❓ Common Questions

Frequently Asked Questions

Quick answers to common questions, technical edge cases, and tax rules.

What is the 4% rule and does it apply to early retirement?

The 4% rule (from the Trinity Study) states that withdrawing 4% of an initial portfolio value, adjusted annually for inflation, historically survived 30-year retirements. For early retirees facing 40 to 50 year horizons, a more conservative Safe Withdrawal Rate (SWR) of 3.25% to 3.5% or dynamic guardrails (like the Guyton-Klinger method) significantly reduces portfolio failure risk.

How do I access retirement accounts before age 59½ without penalties?

Early retirees use three primary pathways: (1) a 5-year Roth conversion ladder, (2) Substantially Equal Periodic Payments (SEPP under IRS Rule 72(t)), and (3) the Rule of 55 for your most recent 401(k) if leaving the company at or after age 55.

What is the difference between Lean FI/RE, Fat FI/RE, and Coast FI/RE?

Lean FI/RE covers minimal baseline expenses (often under $40k/year). Fat FI/RE supports an affluent lifestyle ($100k-$200k+/year) with extensive travel and discretionary spending. Coast FI/RE means you have accumulated enough in retirement accounts that compounding will fund traditional retirement without needing any additional contributions, allowing you to only work to cover current living expenses.

Should I prioritize paying off my mortgage before achieving FI/RE?

Financially, low fixed-rate mortgage debt (e.g., under 4%) typically underperforms broad market index fund returns (8% to 10% historical average) over long periods. However, entering retirement with a paid-off home dramatically lowers your annual baseline spending, thereby reducing your required FI/RE target number and sequence of returns risk.
