How to Calculate Your Net Worth (And Why It Matters)

Key Takeaways

Net worth = Total assets − Total liabilities. It's the most accurate snapshot of your financial health.
Include all assets: investments, retirement accounts, home equity, cash. Include all debts: mortgages, student loans, credit cards.
Track net worth monthly or quarterly — the trend matters more than the number.
Median net worth in the US varies widely by age: ~$27,000 at 25–34, ~$168,000 at 45–54.
Home equity can dominate net worth — liquid vs. illiquid breakdown is important to understand.

Net worth is the single most comprehensive number in personal finance. Unlike income (which measures cash flow) or account balances (which measure one piece), net worth captures your complete financial picture — everything you own minus everything you owe.

Calculating it takes 15–30 minutes the first time. After that, updating it quarterly takes five minutes and gives you the most honest progress report you can have on your financial life.

The Net Worth Formula

Net Worth = Total Assets − Total Liabilities

That's it. The complexity is in accurately listing everything on both sides.

What Counts as an Asset?

Assets are things you own that have monetary value:

Liquid Assets (Easily Accessible)

Checking and savings accounts
Money market accounts
Cash on hand
CDs (Certificates of Deposit)

Investment Assets

Taxable brokerage accounts (stocks, bonds, ETFs, mutual funds)
401(k), 403(b), 457 balances
IRA accounts (Traditional and Roth)
Pension present value (if you can calculate it)
HSA balances
Crypto holdings (at current market value)

Real Property

Primary home current market value
Rental properties market value
Land

Personal Property (Use Resale Value)

Vehicles (Kelley Blue Book value)
Boats, RVs, collectibles with clear market value
Jewelry (appraisal value)

Business Assets

Ownership stake in a business (estimated value)
Accounts receivable (money owed to you)

What to Exclude from Assets

Some "assets" are hard to value or not really sellable:

Personal property with no clear market: furniture, clothing, electronics in normal use
Future income: salary, expected inheritance, Social Security (until actually received)
Illiquid business stakes without a clear valuation

Most financial planners exclude everyday personal property from net worth calculations because the values are speculative and it doesn't paint an accurate financial picture. Your $3,000 sectional sofa isn't going to fund your retirement.

What Counts as a Liability?

Liabilities are everything you owe:

Mortgage balance(s)
Home equity loans / HELOC balances
Auto loan balances
Student loan balances
Credit card balances (current balance, not credit limit)
Personal loans
Medical debt
Money owed to family/friends
Business debts you've personally guaranteed
Tax liabilities (if you owe back taxes)

Example Net Worth Calculation

Let's calculate net worth for a hypothetical 35-year-old household:

Asset	Value
Home (market value)	$380,000
401(k)	$145,000
Roth IRA	$42,000
Taxable brokerage	$28,000
Checking & savings	$22,000
Vehicle (KBB value)	$18,000
Total Assets	$635,000

Liability	Balance
Mortgage balance	$290,000
Student loans	$38,000
Auto loan	$12,000
Credit cards	$4,200
Total Liabilities	$344,200

Net Worth: $635,000 − $344,200 = $290,800

But here's the important breakdown: of that $290,800 net worth, $90,000 is home equity (not easily accessible) and $200,800 is liquid or investment assets. The distinction matters for retirement planning and emergency preparedness.

Average and Median Net Worth by Age

The Federal Reserve's Survey of Consumer Finances provides the most comprehensive data on US net worth by age. These are rough figures — your net worth should be evaluated against your own goals, not just benchmarks.

Age Group	Median Net Worth	Mean Net Worth
Under 35	$39,000	$183,000
35–44	$135,000	$549,000
45–54	$247,000	$975,000
55–64	$365,000	$1,566,000
65–74	$410,000	$1,794,000
75+	$335,000	$1,624,000

Note: Mean is pulled up significantly by the ultra-wealthy. Median is a more representative measure for most households.

A simple benchmark from personal finance: your net worth should be roughly your age × your annual income / 10 (the Thomas J. Stanley "Millionaire Next Door" formula). A 40-year-old earning $80,000 should target $320,000 net worth.

Liquid Net Worth vs. Total Net Worth

It's worth calculating both:

Total net worth: Everything, including home equity and retirement accounts with penalties.

Liquid net worth: Only assets you could convert to cash within 90 days without significant penalties. This excludes home equity (can't easily liquidate), traditional 401k/IRA (10% penalty before 59½), and illiquid investments.

Your liquid net worth tells you how financially resilient you are in a crisis. Your total net worth tells you your overall financial trajectory.

Why Net Worth Matters More Than Income

High-income households can have low or negative net worth. A doctor earning $300,000/year with $400,000 in student loans, a new luxury car, and an expensive mortgage may have a lower net worth than a teacher earning $55,000/year who bought a modest home, invested consistently, and kept lifestyle inflation low.

Net worth rewards the behaviors that actually build wealth:

Living below your means
Investing consistently
Avoiding high-interest debt
Letting compound interest work

How to Track Net Worth Over Time

The trend is more important than any single number. A few approaches:

Quarterly spreadsheet: List all accounts and debts quarterly. Simple, free, and forces you to look at your complete financial picture.

Net worth apps: Tools like Personal Capital (now Empower) or Mint aggregate accounts automatically.

Our Net Worth Calculator: Input your balances and see your complete picture with a breakdown of assets by category.

Tracking net worth monthly (or quarterly) is motivating. When the market drops and your account balances fall, seeing your mortgage paydown partially offsetting it provides perspective. When you see net worth crossing a milestone ($100K, $250K, $500K), it validates the habits.

Frequently Asked Questions

Is it normal to have a negative net worth?

Yes, especially in your 20s when student loans and auto loans often exceed savings. About one in five Americans has a negative or near-zero net worth. It's a starting point, not a permanent condition — consistent saving and debt payoff can swing the needle significantly.

Should I include my 401k in net worth even though I can't access it penalty-free?

Yes — include it in total net worth. Many people track "investable net worth" separately (which excludes home equity and retirement accounts with penalties) for a more conservative picture. Both views are useful.

How often should I calculate my net worth?

Monthly is ideal for people actively paying down debt or building savings. Quarterly is sufficient if your finances are stable. At minimum, check it annually. The act of calculating it forces you to engage with your complete financial picture.

What's a good net worth at 30?

By most benchmarks, $100,000+ is strong for someone earning an average income at 30. The "1x your salary" rule (from Fidelity, which applies to retirement savings alone) would suggest ~$50,000–$80,000 in retirement accounts. But net worth at 30 is heavily influenced by whether you have student loans, what city you live in, and whether you've started investing.

Does home equity count as net worth?

Yes. Home equity (market value − mortgage balance) is a legitimate asset that contributes to net worth. The caveat is that it's illiquid — you can't easily spend home equity without selling or borrowing against the home. Track it in total net worth, but pay attention to your liquid net worth separately.
