What is Chubby FIRE?

Chubby FIRE is early retirement without the extremes. It sits between the bare-bones budgets of Lean FIRE and the luxury of Fat FIRE — a comfortable lifestyle you don't have to constantly budget around.

The typical range is $60,000–$100,000 per year in retirement spending, which translates to roughly $1.5M–$2.5M invested using the 4% rule. That's enough for a paid-off home, regular travel, eating out, and a real emergency buffer — without needing the multi-millions Fat FIRE demands.

Comfortable, Not Cramped

Keep your home and lifestyle. No geographic arbitrage or extreme frugality required.

Realistic to Reach

Attainable for dual-income households saving 25–40% — often within 15–20 years.

Built-in Margin

A larger buffer than Lean FIRE means market dips and surprises don't derail your plan.

Frequently Asked Questions

What is Chubby FIRE?

Chubby FIRE is the middle ground of early retirement - more comfortable than Lean FIRE but short of Fat FIRE luxury. It typically means $60,000-$100,000 per year in retirement spending, which requires roughly $1.5 million to $2.5 million invested. You get a comfortable lifestyle with room for travel, dining out, and discretionary spending without needing the multi-millions that Fat FIRE demands.

How much do I need for Chubby FIRE?

Using the 4% rule (25x annual spending): for $60,000/year you need $1.5 million; for $80,000/year you need $2 million; for $100,000/year you need $2.5 million. Many Chubby FIRE planners target the $2 million range as a comfortable balance. Use our FIRE Number Calculator to find your exact figure based on your spending.

What is the difference between Chubby FIRE and Fat FIRE?

Chubby FIRE is $60,000-$100,000/year in spending ($1.5M-$2.5M invested) - comfortable but mindful. Fat FIRE is $100,000+/year ($2.5M+ invested) - a genuinely luxurious lifestyle with no spending constraints. Chubby FIRE is achievable for many solid earners in 15-20 years, while Fat FIRE usually requires high income and aggressive saving.

What is the difference between Chubby FIRE and Lean FIRE?

Lean FIRE means retiring on under $40,000/year (often $625k-$1M invested), which requires a frugal, intentional lifestyle. Chubby FIRE roughly doubles that budget to $60,000-$100,000/year, removing most of the sacrifice. You can keep a car, travel regularly, and absorb surprises - the trade-off is needing roughly twice the nest egg.

What withdrawal rate should I use for Chubby FIRE?

Most Chubby FIRE planners use 3.5-4%. The classic 4% rule (25x spending) is a reasonable starting point, but because early retirees face 40+ year horizons, many use 3.5% (about 28-29x spending) for extra safety. On a $2 million portfolio, 4% gives $80,000/year while 3.5% gives $70,000/year. Our 4% Rule Calculator lets you stress-test your number.

Is Chubby FIRE realistic?

Yes - Chubby FIRE is one of the most attainable FIRE tiers for dual-income households and solid single earners. If you save 25-40% of a $120k-$180k household income, $1.5M-$2.5M is reachable in 15-20 years thanks to compound growth. It is often the sweet spot: a comfortable retirement without the extreme frugality of Lean FIRE or the very high income Fat FIRE requires.

Retire comfortably. Skip the extremes.
