Chubby FIRE: The Comfortable Middle Ground
Chubby FIRE is what happens when you don't want to scrimp in retirement like Lean FIRE, but you also don't need a $5M+ Fat FIRE portfolio. The target: $2–4 million, supporting a comfortable lifestyle — good food, real travel, nice housing — without the austerity of Lean FIRE or the excess of Fat FIRE.
At 4% withdrawal, $2M generates $6,667/month and $4M generates $13,333/month. Most Chubby FIRE households target spending of $7,000–$12,000/month. Here's your number.

Frequently asked questions
What is Chubby FIRE?
Chubby FIRE is an informal FIRE category for people targeting $2–4 million in retirement savings — comfortably above Lean FIRE ($1–1.5M) and standard FIRE (~$1.5–2M), but below Fat FIRE ($5M+). The Chubby FIRE lifestyle typically involves $7,000–$15,000/month in spending: good housing, travel a few times per year, restaurant meals, but not private jets or second homes. It's comfortable retirement without ostentation.
How much do I need for Chubby FIRE?
The typical Chubby FIRE range is $2–4M, supporting $6,700–$13,333/month at the 4% withdrawal rate. Your specific number depends on your expenses. At $8,000/month ($96,000/year), you need $2.4M. At $10,000/month, you need $3M. At $12,000/month, you need $3.6M. Use the table below to find your number.
What's the difference between Chubby FIRE and Fat FIRE?
Fat FIRE is generally defined as $5M+ targeting $200,000+/year in spending — think luxury travel, premium housing in expensive cities, helping kids financially. Chubby FIRE targets $2–4M with $80,000–$150,000/year in spending — comfortable and stress-free, but not extravagant. Many FIRE practitioners prefer Chubby FIRE because it's achievable on a dual high-income household without requiring 20+ years of aggressive saving.
What income level leads to Chubby FIRE?
Chubby FIRE is commonly achieved by dual-income professional households earning $250,000–$500,000/year with savings rates of 30–50%. A household saving $80,000/year ($6,667/month) at 7% returns reaches $2M in approximately 14 years from $0. Starting with $500,000 already saved reduces the timeline to about 10 years. Tech workers, doctors, lawyers, and finance professionals commonly target Chubby FIRE.
Should I target Chubby FIRE or keep going to Fat FIRE?
This is a classic 'one more year' risk. Chubby FIRE at $2.5M (supporting $8,333/month) is likely enough for most households. Continuing to accumulate from $2.5M to $5M Fat FIRE might take 10+ additional years of working. The opportunity cost is 10 years of retirement living. Unless you genuinely need Fat FIRE spending levels, Chubby FIRE is often the rational stopping point.
