ABOUT YOU
SAVINGS AND INVESTING
Using defaults: filing single, 401(k) 8%, moderate returns, 4% withdrawal, 2.5% inflation. Saving is estimated from your after-tax income less spending.
Larger budgets make account mix and withdrawal tax matter more

In simple mode the whole portfolio is treated as one taxable account, so no tax on withdrawals from traditional accounts is applied. .

How this estimate works
Estimates the portfolio you need to cover your full lifestyle at your chosen withdrawal rate, with the spending adjusted for inflation each year.Returns use your selected volatility preset. Inflation and salary growth compound annually, and take-home pay is recalculated each year through the tax engine, with pay growing at the salary-growth rate and the tax brackets, deductions and 401(k) limit indexed to inflation. Each year's saving is added as twelve monthly end-of-month deposits. This is a planning estimate, not financial or tax advice.

Chubby FIRE is commonly framed as roughly $100,000 to $150,000 in annual spending, which at a 4% withdrawal rate implies a portfolio of about $2.5 million to $3.75 million. Your exact number depends on your spending and withdrawal-rate assumptions.

How Chubby FIRE actually works

Chubby FIRE uses the same core math as traditional FIRE: annual spending divided by your withdrawal rate. The difference is a more comfortable spending target, which raises the portfolio you need but buys a materially higher standard of living.

At $100,000 per year in expenses and a 4% withdrawal rate, the target portfolio is about $2.5 million. At $150,000 per year, it is about $3.75 million. The higher spending is the whole point, Chubby FIRE trades a bigger number for a roomier life.

What changes your Chubby FIRE number most

Target spending

The comfort level you plan for is the biggest lever. Every $10,000 of annual spending adds about $250,000 to the target at a 4% rate.

Withdrawal rate

A more conservative withdrawal rate raises the target. Many Chubby FIRE planners favor a cushion given the longer horizons of early retirement.

Healthcare & travel

Discretionary categories like travel, dining, and pre-Medicare healthcare are often what separates Chubby FIRE from a leaner plan.

Location

Cost of living still matters. The same comfortable lifestyle costs far less in some cities than others, which changes the target directly.

Who Chubby FIRE is usually best for

Chubby FIRE tends to fit people who want financial independence without giving up a comfortable lifestyle, those who would rather work a bit longer or save a bit more than commit to a tight budget for decades.

It is a popular middle ground for higher earners who find Lean FIRE too restrictive but do not need the luxury spending (or the much larger portfolio) that Fat FIRE requires.
