What Is Chubby FIRE?
Chubby FIRE is a financial independence strategy that targets an above-average level of annual spending in retirement — typically $75,000 to $150,000 per year. It sits between regular FIRE and Fat FIRE, offering a comfortable lifestyle with room for travel, dining, hobbies, and a financial cushion, without requiring the multi-million dollar portfolios that Fat FIRE demands. The term comes from the broader FIRE (Financial Independence, Retire Early) movement, where the goal is to accumulate enough wealth so that investment returns cover your living expenses indefinitely.
Our free Chubby FIRE calculator helps you determine your target number, project your net worth growth over time, and estimate when you can achieve financial independence. It accounts for contribution growth over time, reflecting the reality that most people increase their savings as their income rises throughout their career.

Enter Your Current Net Worth
Start with your total investable assets — stocks, bonds, savings accounts, retirement accounts, and other investments. Exclude your primary residence and personal property unless you plan to sell them.

Who Is Chubby FIRE For?
Chubby FIRE is the sweet spot for a large segment of high-earning professionals. It is particularly well-suited for:
Mid-to-Senior Professionals
Individuals or households earning $100k-$250k who can save 30-50% of their income while maintaining a good quality of life during their working years.
Dual-Income Households
Couples with combined incomes who can split savings responsibilities and reach the Chubby FIRE target faster through coordinated financial planning.
Lifestyle-Conscious Planners
People who want to travel regularly, enjoy dining out, pursue hobbies, and have a financial buffer — without needing luxury-level spending.
Risk-Aware Retirees
Those who want a larger safety margin than regular FIRE provides, with enough cushion to handle healthcare costs, market downturns, and unexpected expenses.
Strategies to Reach Chubby FIRE Faster
Target a 40-50% Savings Rate
The savings rate is the most impactful factor. Aim for 40-50% of your income. Every dollar saved is a dollar that compounds for decades toward your Chubby FIRE goal.
Grow Your Income Strategically
Career advancement, skill development, and strategic job changes can boost your income significantly. Channel raises and bonuses directly into investments.
Invest in Low-Cost Index Funds
Broad market index funds like VTI or VTSAX provide diversified exposure with minimal fees. Over decades, even small fee differences compound into significant wealth differences.
Maximize Tax-Advantaged Accounts
Max out your 401(k), IRA, HSA, and consider Mega Backdoor Roth contributions. Tax-efficient investing can save hundreds of thousands over a career.
Avoid Lifestyle Inflation
As your income grows, resist the urge to proportionally increase spending. The gap between income and expenses is what fuels your Chubby FIRE journey.
Start Early
Compound interest is exponential. Starting 10 years earlier can nearly double your final portfolio. Time in the market beats timing the market for long-term wealth building.
Chubby FIRE Example Scenario
The Typical Chubby FIRE Path
Consider a 30-year-old with $250,000 in investments, saving $1,000 per month with 10% annual contribution growth, earning 7% annual returns, and targeting $100,000 per year in retirement spending at a 4% withdrawal rate. Their Chubby FIRE number is $2,500,000. With these assumptions, they could reach Chubby FIRE around age 51 — retiring roughly 14 years earlier than the traditional retirement age of 65.
What $100,000/Year Buys in Retirement
With $100,000 per year in retirement spending, you can comfortably cover housing costs in most US cities, health insurance premiums, regular domestic and occasional international travel, dining out several times a week, hobbies and entertainment, and still maintain an emergency fund. It is a lifestyle that feels abundant without being extravagant.
Chubby FIRE Withdrawal Strategies
The 4% Rule (Fixed Percentage)
Withdraw 4% of your portfolio in year one, then adjust for inflation annually. Based on the Trinity Study, this approach has historically sustained portfolios for 30+ years. For Chubby FIRE with longer time horizons, some planners recommend a more conservative 3.5% rate.
Variable Percentage Withdrawal
Withdraw a fixed percentage of your current portfolio each year (e.g., 3.5%). This naturally adjusts spending to market conditions — you spend more in good years and less in bad years, significantly reducing the risk of portfolio depletion.
Bucket Strategy
Divide your portfolio into three buckets: short-term (1-2 years of expenses in cash/bonds), medium-term (3-7 years in balanced funds), and long-term (remaining in stocks). This provides spending stability during market downturns while maintaining growth potential.
