ChubbyFIRE: The Middle Ground Between FIRE and FatFIRE

What if you want to retire early, but you don't want to spend your retirement counting every dollar?

You also don't necessarily need a $10 million portfolio and a luxury lifestyle.

There is a middle ground.

It is often called ChubbyFIRE.

ChubbyFIRE sits somewhere between traditional FIRE and FatFIRE. The idea is to accumulate enough wealth to retire early while maintaining a comfortable lifestyle, without necessarily trying to fund an especially expensive retirement.

Think of it this way:

• LeanFIRE: Spend as little as possible so you can retire with a smaller portfolio.
• Traditional FIRE: Build enough wealth to cover your planned lifestyle indefinitely.
• ChubbyFIRE: Retire early with a comfortable budget and some room for extras.
• FatFIRE: Build a very large portfolio so you can maintain a high-spending lifestyle.

The boundaries between these categories are not official. Different FIRE communities use different definitions and spending levels.

What matters is the underlying idea: ChubbyFIRE is about having enough financial independence that retirement doesn't require you to live extremely frugally.

What Is ChubbyFIRE?

ChubbyFIRE generally describes a person or couple who wants financial independence and early retirement while maintaining a relatively comfortable standard of living.

You might still travel.

You might eat at restaurants regularly. You might live in a nice home, own a reliable vehicle, pursue hobbies and spend money on experiences.

But you aren't necessarily trying to fly first class everywhere, own multiple luxury properties or spend hundreds of thousands of dollars every year.

The goal is comfort and flexibility.

Why Does ChubbyFIRE Exist?

The original FIRE movement became popular partly because it challenged the idea that people have to work until their 60s or 70s.

But some early FIRE approaches emphasized aggressive savings and extremely low spending.

That works for some people.

It doesn't work for everyone.

Imagine someone earning $180,000 a year who saves aggressively and eventually reaches financial independence. They could technically retire, but perhaps they don't want to spend the next 40 years living on $40,000 a year.

At the other extreme, they may not need $250,000 or $300,000 a year either.

ChubbyFIRE is essentially the space in between.

How Much Money Do You Need for ChubbyFIRE?

There is no official ChubbyFIRE number.

You will see different definitions online, but a better approach is to ignore the label and calculate your own required portfolio.

Start with your expected annual retirement spending.

For example, suppose a couple wants to spend $120,000 per year in retirement.

Using a simple 4% withdrawal-rate illustration:

$120,000 ÷ 0.04 = $3 million

That gives you a starting point of approximately $3 million.

If you wanted to use a 3.5% withdrawal rate instead:

$120,000 ÷ 0.035 = approximately $3.43 million

And at 3%:

$120,000 ÷ 0.03 = $4 million

These are simple mathematical examples, not guarantees.

Your appropriate withdrawal strategy depends on your retirement age, expected retirement length, portfolio, taxes, other income sources and willingness to adjust spending.

ChubbyFIRE vs. FatFIRE

The difference between ChubbyFIRE and FatFIRE is primarily about spending.

Someone pursuing ChubbyFIRE might want a comfortable lifestyle with plenty of discretionary spending.

Someone pursuing FatFIRE generally wants a much larger spending budget and therefore needs a substantially larger portfolio.

Consider a simplified example:

• A ChubbyFIRE household might target $120,000 to $150,000 of annual spending.
• A FatFIRE household might target $200,000, $250,000 or substantially more.

These ranges are only illustrations. There is no universal line separating the two.

The important difference is the lifestyle you are trying to fund.

ChubbyFIRE vs. LeanFIRE

The difference becomes even clearer when comparing ChubbyFIRE with LeanFIRE.

A LeanFIRE retiree might deliberately choose a very inexpensive lifestyle to reach financial independence as quickly as possible.

A ChubbyFIRE retiree is generally willing to work longer or save more in exchange for having more money available to spend in retirement.

For example, imagine two people each earn $150,000.

Person A saves aggressively and wants to retire as soon as possible. They are comfortable living on $50,000 a year.

Person B is willing to work several additional years because they want to spend $100,000 or $120,000 a year after retiring.

Neither approach is inherently right or wrong.

They simply prioritize different things.

What Does a ChubbyFIRE Lifestyle Look Like?

This is where the concept becomes more useful than a simple portfolio number.

A ChubbyFIRE retirement might include:

• A comfortable home
• Regular restaurant meals
• Several vacations each year
• Hobbies and recreational activities
• A reliable vehicle or two
• Regular entertainment
• Helping children occasionally
• Some charitable giving
• A reasonable emergency fund
• Room for unexpected expenses

The common theme is that you don't have to eliminate everything enjoyable from your budget just to remain financially independent.

ChubbyFIRE Is About Having a Margin of Safety

One of the biggest advantages of building a larger portfolio is that you can have some breathing room.

Suppose your basic retirement expenses are $70,000 a year, but you have enough assets to support $120,000 of annual spending.

That difference gives you options.

During a strong market, you might travel more.

During a major market downturn, you could temporarily reduce discretionary spending.

If your roof needs replacing, your car breaks down or you need to help a family member, you have more room to absorb the expense.

You don't necessarily need to maintain your maximum spending level every single year.

Don't Forget Taxes

A common mistake in FIRE planning is to think about spending only in terms of gross withdrawals.

If you want to spend $120,000 after tax, you may need to withdraw considerably more than $120,000 from your investment accounts.

The amount depends on where your money is held and how you withdraw it.

A portfolio containing Traditional IRA or 401(k) assets can produce taxable income when money is withdrawn. Roth accounts can have different tax treatment. Taxable investment accounts introduce capital gains, dividends and other tax considerations.

Social Security can also become part of the calculation.

This is one reason a ChubbyFIRE plan should model taxes rather than simply multiplying annual spending by 25.

Healthcare Can Change the Math

If you plan to retire before becoming eligible for Medicare, healthcare deserves special attention.

You may need to purchase health insurance for several years before Medicare begins.

Even after Medicare eligibility, premiums, supplemental coverage, prescriptions and out-of-pocket expenses can add significantly to your retirement budget.

A comfortable retirement budget should include a realistic healthcare allowance.

What About Your House?

Your home can make ChubbyFIRE easier, but only if you account for it correctly.

Suppose you own a $700,000 home outright.

That is a valuable asset, but if you plan to live in the home for the rest of your life, you probably shouldn't count the full $700,000 as money available to fund retirement spending.

You still have property taxes, insurance, maintenance, utilities and other housing costs.

On the other hand, owning your home outright can dramatically reduce your monthly housing expense compared with renting or carrying a mortgage.

Housing is therefore an important part of determining your ChubbyFIRE number.

Should You Include Social Security?

If you are planning a U.S. retirement, Social Security can make a significant difference to the amount your investment portfolio needs to provide.

Imagine your desired retirement spending is $120,000 per year.

If Social Security eventually provides $40,000 a year for your household, your portfolio doesn't necessarily need to generate the entire $120,000 indefinitely.

But there is an important timing issue.

If you retire at 50, Social Security may not begin for many years. Your portfolio may therefore need to fund a much larger portion of your spending during the early years of retirement.

This is why a year-by-year retirement projection can be more useful than a simple portfolio calculation.

ChubbyFIRE and the "Go-Go Years"

Your retirement spending probably won't remain constant throughout your life.

Many retirees spend more during the first years of retirement.

You finally have time to travel. You want to visit family. You might renovate the house, buy an RV or pursue an expensive hobby.

Later, spending may slow down.

You may travel less and spend more time at home.

Eventually, healthcare and long-term care may become larger expenses.

A ChubbyFIRE plan can account for those changes rather than assuming you will spend exactly the same amount every year.

Can ChubbyFIRE Include Travel?

Absolutely.

In fact, travel is one of the expenses that can make a ChubbyFIRE budget meaningfully different from a LeanFIRE budget.

Consider a couple that spends $15,000 a year on travel.

That single category represents more than $1,000 per month of annual spending.

Over a 30-year retirement, the amount is substantial.

But if travel is one of the reasons you want to retire early, it belongs in the plan.

There is little value in reaching financial independence only to discover that the retirement budget doesn't include the things you actually wanted to do.

What If Markets Crash After You Retire?

This is one of the biggest risks for anyone retiring early.

Imagine retiring at 50 with a $3 million portfolio.

A major market decline shortly after retirement could significantly reduce the value of your investments at exactly the time you are beginning withdrawals.

This is known as sequence-of-returns risk.

A long-term average return doesn't tell you what happens along the way.

This is why it can be useful to test your retirement plan against different market conditions, including periods of poor returns and high inflation.

ChubbyFIRE Can Be More Flexible Than You Think

One advantage of a comfortable retirement budget is that not all spending is essential.

Your mortgage or rent is probably essential.

Food and utilities are essential.

But another international vacation may not be.

That distinction can give you flexibility during difficult markets.

If your investments fall sharply, you might postpone a large trip rather than selling investments at depressed prices.

Having discretionary spending built into your budget can therefore provide a useful safety valve.

How Do You Know When You've Reached ChubbyFIRE?

Don't focus entirely on a headline number.

Instead, ask whether your portfolio can support the life you actually want to live.

Start by estimating:

• Housing expenses
• Food
• Transportation
• Healthcare
• Travel
• Entertainment
• Hobbies
• Taxes
• Insurance
• Gifts and family support
• Charitable giving
• Unexpected expenses

Then determine how much income your investments need to provide after accounting for pensions, Social Security and other sources of income.

That gives you a much more meaningful ChubbyFIRE number than an arbitrary portfolio threshold.

A Simple ChubbyFIRE Example

Consider a couple who wants to retire at 55.

They estimate that they will need $110,000 per year after taxes to maintain their lifestyle.

They own their home outright and expect $35,000 per year of combined Social Security beginning later in retirement.

During the first several years, however, their investment portfolio will need to provide most of their income.

Their plan therefore needs to answer several questions:

• How large does the portfolio need to be at age 55?
• How much should they withdraw during the first decade?
• When should they claim Social Security?
• Which accounts should they use first?
• How much will they pay in taxes?
• What happens if the market falls 30%?
• What happens if inflation remains high?
• What happens if one spouse lives into their 90s?

These are much more useful questions than simply asking whether $3 million is enough for ChubbyFIRE.

Fun Facts About ChubbyFIRE

• ChubbyFIRE has no official dollar threshold. The term is used differently by different people in the FIRE community.
• It is about lifestyle as much as wealth. Two households with identical portfolios can have very different FIRE targets because their spending habits are different.
• Travel can dramatically change your number. A couple spending $15,000 a year on travel needs substantially more wealth than a couple who rarely travels.
• A paid-off house doesn't eliminate housing costs. Property taxes, insurance, utilities and maintenance continue.
• ChubbyFIRE can provide a buffer. A larger portfolio can give you discretionary spending that can be reduced temporarily when markets are struggling.

The Bottom Line

ChubbyFIRE is the middle ground between extreme frugality and an extremely high-spending retirement.

It is for people who want financial independence and potentially early retirement, but who also want enough money to enjoy a comfortable lifestyle.

There is no universal ChubbyFIRE number.

Your number depends on your spending, retirement age, housing, taxes, healthcare, Social Security, investment portfolio and how much flexibility you want.

The best place to start is with the retirement you actually want.

Figure out what that lifestyle costs. Then work backward to determine how much you need to save, when you can retire and how much margin you want between your basic expenses and your total spending budget.
