Where Your FIRE Number Comes From
At $20,400/year, you're in ultra-lean territory. Make sure you have a 15%+ buffer for unexpected expenses.
What is Lean FIRE?
Lean FIRE is the fastest path to early retirement. Instead of waiting to save millions, you embrace minimalism and retire on a lean budget - typically under $40,000 per year.
The math is simple: lower expenses = lower savings target = earlier retirement. Someone needing $30k/year only needs $750,000 (vs. $1.5M for $60k/year). That could mean retiring 10+ years sooner.
Retire Faster
Need less saved means reaching FI years earlier than traditional paths.
Location Freedom
Low costs unlock geographic arbitrage - retire abroad or in LCOL areas.
Simple Living
Less stuff, less stress. Focus on experiences over possessions.

Frequently Asked Questions
Can you live on $25,000 a year in 2026?
Yes, but location is critical. In states like New Mexico with $0 healthcare premiums (Turquoise Plan) and zero-fare transit, $25k provides a comfortable lifestyle with a 15% buffer. In states without healthcare backstops, $25k becomes tight due to $100-150/month insurance costs.
What is Lean FIRE?
Lean FIRE is the minimalist approach to early retirement. You save aggressively to retire on a lean budget - typically under $40,000 per year. It requires less money than traditional FIRE ($625k-$1M vs $1.5M+) but means adopting a frugal, intentional lifestyle.
How much do I need for Lean FIRE?
Using the 4% rule (25x annual expenses): For $25,000/year you need $625,000. For $30,000/year, you need $750,000. For $40,000/year, you need $1 million. Many Lean FIRE practitioners retire on $500k-$800k by keeping expenses very low.
What are the best cities for Lean FIRE in 2026?
Albuquerque, NM leads due to $0 healthcare (NM Turquoise Plan) and zero-fare transit. Cleveland, OH and Pittsburgh, PA offer robust transit, affordable housing ($750-900/mo studios), and excellent library systems. All three enable car-free living.
What is the 2026 healthcare cliff for Lean FIRE?
Federal enhanced ACA subsidies expired Dec 31, 2025. Without state intervention, someone earning $25,000 (156% FPL) now pays $100-150/month for health insurance. New Mexico, Massachusetts, and New Jersey have state backstops keeping premiums at $0-53/month.
What are the risks of Lean FIRE?
The main risks are: less buffer for unexpected expenses (healthcare, home repairs), inflation eroding purchasing power over a long retirement, and lifestyle feeling restrictive. Having a 15%+ unallocated buffer and choosing states with healthcare protections mitigates these risks.
Can I do Lean FIRE without a car?
Car-free living is almost mandatory for $25k Lean FIRE. Car ownership costs $8,000+/year (32% of a $25k budget). Cities like Albuquerque (zero-fare ART), Cleveland (RTA HealthLine), and Pittsburgh offer transit access. E-bikes extend your range for $1,000 upfront vs $8,000/year.
What is the difference between Lean FIRE "survival" and "thriving" mode?
Survival mode: 95%+ of income goes to fixed costs (rent, food, utilities), leaving no buffer for emergencies or leisure. Thriving mode: strategic location choice reduces fixed costs to 70%, creating a 15% emergency buffer and funds for hobbies. The key is substituting private spending with public amenities (libraries, free museums, community centers).
What groceries budget is realistic for Lean FIRE?
Budget $300/month ($10/day) for single-person groceries in 2026. Shop at Aldi (10-20% cheaper than Walmart for produce and meat). Focus on eggs ($3.47/dozen), beans, lentils, seasonal produce, and loss leaders. This assumes 95% home cooking - dining out is a luxury item on Lean FIRE.
How does inflation affect Lean FIRE?
Lean FIRE has less margin for inflation. CPI rose 2.7% in 2025, with food up 3.1% and energy up 6-10%. A 15% unallocated buffer absorbs annual increases. The 4% withdrawal rule includes inflation adjustment, but tight budgets may need dynamic spending (cut 10% in down years).
Less is more. Retire sooner.
