Question 1

What is Chubby FIRE?

Accepted Answer

Chubby FIRE is the middle tier of Financial Independence Retire Early, targeting $80,000-$120,000 in annual spending. Portfolio requirement is typically $2-3.5M depending on safe withdrawal rate.

Question 2

Chubby FIRE vs Fat FIRE \u2014 which is right for me?

Accepted Answer

Chubby FIRE works if your target lifestyle is comfortable but not luxurious \u2014 owning a modest home, traveling 2-3 times per year, dining out regularly. Fat FIRE ($150k+ spending) suits luxury travel, larger homes, or multiple homes.

Question 3

Should I use 4% rule for Chubby FIRE?

Accepted Answer

The classic 4% rule fits 30-year retirements. For Chubby FIRE retirees in their 40s-50s with potential 40-50 year horizons, a 3.5-3.75% SWR provides more historical safety. Pair with dynamic spending rules for added flexibility.

Question 4

Can I use real estate income for Chubby FIRE?

Accepted Answer

Yes \u2014 rental income diversifies away from market sequence risk. Many Chubby FIRE plans combine a $1.5-2M index portfolio with 2-4 rental properties producing $30-50k net cash flow, reducing the SWR pressure on the financial portfolio.

Question 5

What if I retire and run short?

Accepted Answer

Chubby FIRE retirees often retain employability \u2014 consulting, part-time work, or sabbatical-then-return models. Coast FIRE Calculator can help model returning to part-time work for 5-10 years to bridge a portfolio shortfall.

Question 6

How is Chubby FIRE taxed?

Accepted Answer

Most Chubby FIRE spending comes from taxable brokerage and pre-tax 401k/IRA distributions before 65. Long-term capital gains under $94k (married filing jointly 2026) are taxed at 0%; gains above that are 15%. Strategic Roth conversions in low-income early years reduce future RMD tax drag.

Question 7

How accurate is this chubby FIRE calculator?

Accepted Answer

The portfolio-target math is exact for your chosen SWR (spend ÷ SWR). The years-to-FIRE projection uses a compound-growth formula with your real return rate — accurate within 1-2 years assuming the input return holds. The real uncertainty is market returns; run the calculator with 4%, 5%, and 6% real return scenarios to see the spread. The historical S&P 500 real return is ~7% over 100 years; using 5% gives a reasonable buffer.

Question 8

What is the difference between chubby FIRE and lean FIRE?

Accepted Answer

Lean FIRE targets $30-50k annual spend (portfolio ~$750k-1.25M at 4% SWR). Chubby FIRE targets $80-120k spend (~$2-3M portfolio). Lean FIRE requires aggressive frugality — small home, no luxury travel, minimal discretionary. Chubby FIRE allows a comfortable middle-class lifestyle: mortgage-free home, 2-3 international trips/year, dining out, hobbies. Pick lean FIRE for speed-to-quit, chubby for lifestyle margin.
