The Quick Answer
Net worth is the total value of everything you own (assets) minus everything you owe (liabilities), representing your overall financial position at a point in time.
Net Worth = Total Assets - Total Liabilities
If you own $200,000 in assets and owe $120,000 in debts, your net worth is $80,000. The number can be positive, zero, or negative. It is the single best snapshot of your overall financial health.

What Counts as an Asset
Assets are anything you own that has monetary value. For a personal net worth calculation, the major categories are:
Cash and cash equivalents
- Checking accounts
- Savings accounts
- Money market accounts
- Certificates of deposit (CDs)
Investments
- Brokerage accounts (stocks, bonds, mutual funds, ETFs)
- Retirement accounts (401(k), 403(b), IRA, Roth IRA)
- Health Savings Accounts (HSA)
- Cryptocurrency holdings
Real property
- Primary residence (current market value, not purchase price)
- Rental properties
- Land
Personal property
- Vehicles (current market value, not purchase price)
- High-value jewelry, art, or collectibles
- Business ownership interests
Use current market values, not what you originally paid. A car bought for $30,000 three years ago might be worth $18,000 today. A home purchased for $250,000 might now be worth $320,000. Net worth reflects present reality.
What Counts as a Liability
Liabilities are all debts and financial obligations you owe:
- Mortgage balance (remaining principal)
- Student loan balance
- Auto loan balance
- Credit card balances
- Personal loans
- Medical debt
- Home equity loans or lines of credit (HELOC)
- Any other outstanding debt
Use current outstanding balances, not the original loan amounts. If you borrowed $200,000 for a mortgage and have paid it down to $175,000, the liability is $175,000.
Worked Examples
Example 1: Young Professional, Age 28
| Assets | Value |
|---|---|
| Savings account | $15,000 |
| 401(k) balance | $22,000 |
| Car (market value) | $18,000 |
| Total Assets | $55,000 |
| Liabilities | Balance |
|---|---|
| Student loans | $35,000 |
| Car loan | $12,000 |
| Credit card debt | $3,000 |
| Total Liabilities | $50,000 |
Net Worth = $55,000 - $50,000 = $5,000
A net worth of $5,000 at age 28 is modest but positive. The student loans are the largest drag, but the 401(k) is already building. As the student loans are paid down and the retirement account grows, net worth will accelerate.
Example 2: Mid-Career Professional, Age 45
| Assets | Value |
|---|---|
| Savings and checking | $40,000 |
| 401(k) and IRA | $285,000 |
| Home (market value) | $380,000 |
| Total Assets | $705,000 |
| Liabilities | Balance |
|---|---|
| Mortgage balance | $210,000 |
| Car loan | $15,000 |
| Total Liabilities | $225,000 |
Net Worth = $705,000 - $225,000 = $480,000
At age 45, this person has $480,000 in net worth. The home is the largest asset, but after subtracting the mortgage, it contributes $170,000 in equity. The retirement accounts at $285,000 represent the largest single component of net worth.
Age-Based Net Worth Benchmarks
The Federal Reserve Survey of Consumer Finances (2022) provides median and mean net worth data by age group:
| Age Group | Median Net Worth | Mean Net Worth |
|---|---|---|
| Under 35 | $39,000 | $183,500 |
| 35-44 | $135,600 | $549,600 |
| 45-54 | $247,200 | $975,800 |
| 55-64 | $364,500 | $1,566,900 |
| 65-74 | $409,900 | $1,794,600 |
| 75+ | $335,600 | $1,624,100 |
The large gap between median and mean shows that net worth is heavily skewed by wealthy households. The median (middle value) is a more representative benchmark for most people than the mean (average).
Net worth typically peaks between ages 65 and 74, then declines as retirees spend down savings.
The "Multiply by Age" Rule of Thumb
Thomas Stanley, in his book The Millionaire Next Door, proposed a simple formula for expected net worth:
Expected Net Worth = (Age x Annual Pre-Tax Income) / 10
Examples
- Age 30, earning $50,000: Expected net worth = (30 x $50,000) / 10 = $150,000
- Age 40, earning $80,000: Expected net worth = (40 x $80,000) / 10 = $320,000
- Age 50, earning $100,000: Expected net worth = (50 x $100,000) / 10 = $500,000
Stanley classified people as:
- Prodigious Accumulator of Wealth (PAW): Net worth is 2x or more the expected amount
- Average Accumulator of Wealth (AAW): Net worth is near the expected amount
- Under Accumulator of Wealth (UAW): Net worth is half or less the expected amount
This formula has limitations. It is less useful for people under 30 (who have not had enough time to accumulate), people with very high or very low incomes, or people who recently changed income levels significantly. It works best as a rough directional benchmark for mid-career professionals.
Liquid Net Worth vs. Total Net Worth
Some financial planners distinguish between total net worth and liquid net worth:
Liquid Net Worth = Liquid Assets - Total Liabilities
Liquid assets are things you can convert to cash quickly without significant loss of value: savings accounts, brokerage accounts, and similar holdings. Liquid net worth excludes:
- Home equity (selling a home takes months)
- Retirement accounts (penalties for early withdrawal)
- Personal property (uncertain resale value)
A person with a $500,000 total net worth might have a liquid net worth of only $80,000 if most of their wealth is in home equity and retirement accounts. Both numbers are useful. Total net worth measures overall financial position. Liquid net worth measures financial flexibility and emergency resilience.
How to Track Net Worth Over Time
The value of net worth is not in a single number but in the trend. A consistent upward trajectory means your financial decisions are working.
Practical tracking approach:
- Pick a regular interval -- quarterly or annually
- List all assets at current market values
- List all liabilities at current balances
- Calculate net worth
- Compare to previous periods
What moves net worth up:
- Saving and investing regularly
- Paying down debt principal
- Asset appreciation (home values, investment growth)
What moves net worth down:
- Taking on new debt
- Spending more than you earn
- Market declines (temporary if you do not sell)
- Asset depreciation (vehicles, equipment)
Short-term market fluctuations will cause net worth to bounce around. A retirement portfolio dropping 15% in a bad quarter does not mean your financial plan failed. Focus on the multi-year trend.
Common Mistakes in Net Worth Calculations
Using purchase price instead of current value. Your car is worth what someone will pay for it today, not what you paid three years ago. Your home is worth its current appraised or comparable market value, not the 2019 purchase price.
Forgetting retirement accounts. A 401(k) with $200,000 is a real asset even though you cannot spend it today without penalties. Excluding it understates your financial position.
Including expected future income. Net worth is a snapshot of right now. Future salary, expected inheritance, or anticipated bonuses are not assets until they are received.
Double-counting home equity. If you list your home at $400,000 (asset) and your mortgage at $250,000 (liability), the formula already calculates the $150,000 equity. Do not add equity as a separate line item.
Overstating personal property. That $3,000 couch is worth maybe $500 on the resale market. Either exclude everyday personal property or use conservative resale estimates.
Frequently Asked Questions
What is a good net worth for my age?
According to the 2022 Federal Reserve Survey of Consumer Finances, the median net worth by age group is: under 35 about $39,000; 35-44 about $135,600; 45-54 about $247,200; 55-64 about $364,500; 65-74 about $409,900. These are medians, meaning half of households in each group have more and half have less.
Is my home part of my net worth?
Yes. Your home's current market value is an asset. Your outstanding mortgage balance is a liability. The difference -- your home equity -- is the net contribution your home makes to your net worth. A $350,000 home with a $200,000 mortgage adds $150,000 to net worth.
Can net worth be negative?
Yes. Negative net worth means your total liabilities exceed your total assets. This is common for recent college graduates with student loans and limited savings. It typically improves as debts are paid down and assets grow over time.
How often should I calculate net worth?
Quarterly or annually is sufficient for most people. Monthly calculations can cause unnecessary stress from short-term market movements. The goal is to track the long-term trend, not react to daily fluctuations.
Should I include my car in net worth?
Yes. Include the current market value (check Kelley Blue Book or similar sources), not the purchase price. If you have an auto loan, include that balance as a liability. The net contribution is market value minus loan balance.
Does net worth include retirement accounts?
Yes. Include current balances of 401(k), IRA, Roth IRA, and similar accounts. Some people also calculate a separate "liquid net worth" that excludes retirement accounts, since those funds carry early withdrawal penalties.
What is the difference between net worth and income?
Income is a flow of money over time. Net worth is a snapshot at a point in time. High income does not guarantee high net worth if spending matches or exceeds earnings. Moderate income with disciplined saving can produce substantial net worth over decades.
How do I increase my net worth?
Three levers: increase assets (save more, invest, grow income), decrease liabilities (pay down debt), or both simultaneously. The most impactful strategy is usually increasing savings rate while systematically eliminating high-interest debt.
Should I include personal property like furniture and clothing?
Most financial planners exclude everyday personal property because it depreciates rapidly and has uncertain resale value. Include high-value items like jewelry, art, or collectibles only if you have a reliable estimate of their current market value.
What is the Millionaire Next Door net worth formula?
The formula from Thomas Stanley's book is: Expected Net Worth = (Age x Annual Pre-Tax Income) / 10. A 40-year-old earning $80,000 per year should have approximately $320,000 in net worth by this benchmark. It works best for people over 30 with stable careers.
