Early Retirement Guide
FIRE strategies, the real cost of retiring at 55, when you can retire, and what happens if savings run dry.
Your FIRE Number
Annual spending × 25 = retirement savings needed. For early retirement (40+ year horizon), use × 28–30 (3.3–3.5% rate).

Best Strategies to Retire Early
Maximize your savings rate
FIRE requires 40–60%+ savings rate. Every $1 not spent has a triple effect: reduces your spending target (25×), adds to your balance, and reduces your FIRE number simultaneously.
Use tax-advantaged accounts
Max 401(k) ($23,500/yr in 2025 + $7,500 catch-up), Roth IRA ($7,000), and HSA ($4,300 individual). These compound tax-free and are crucial for an early retirement timeline.
Plan the healthcare bridge
From 55–65, private health insurance is the biggest early retirement wildcard. Budget $700–$1,500/month per person and check ACA marketplace subsidies if income drops below 400% of FPL.
Build a withdrawal sequencing plan
Draw from taxable accounts first (capital gains treatment), then traditional 401k/IRA, then Roth last. This minimizes lifetime taxes and makes Roth conversions possible in low-income early retirement years.
