Net Worth

FundamentalGeneral Investing4 min read

Quick Definition

The total value of everything you own (assets) minus everything you owe (liabilities) — the single best measure of your overall financial health.

Key Takeaways

  • Net worth = Total Assets minus Total Liabilities — it's the single best snapshot of your overall financial health
  • Net worth matters more than income: a high earner with massive debt has less wealth than a moderate earner who saves and invests consistently
  • The Millionaire Next Door formula: Expected Net Worth = (Age × Annual Income) ÷ 10 — above 2x is "prodigious," below 0.5x is "under-accumulating"
  • Track net worth monthly — the combination of increasing assets and decreasing debts creates powerful momentum over time
  • The median U.S. household net worth is ~$192,000 — reaching the top 20% requires ~$500K–$2M depending on age group

What Is Net Worth?

Net worth is the most comprehensive measure of financial health, calculated as the total value of all your assets minus all your liabilities. It represents what you would have left if you sold everything you own and paid off every debt. Unlike income — which measures money flowing in — net worth measures accumulated wealth.

Net Worth Formula:

Net Worth = Total Assets - Total Liabilities

What Counts as Assets and Liabilities:

Assets (What You Own)Liabilities (What You Owe)
Cash & savings accountsMortgage balance
Investment accounts (401k, IRA, brokerage)Student loans
Home market valueAuto loans
Vehicle valueCredit card balances
Real estate investmentsPersonal loans
Business equityMedical debt
CryptocurrencyHome equity loans
Personal property (jewelry, art)Tax obligations
Cash value of life insuranceOther debts

The Millionaire Next Door Formula:

Thomas Stanley's formula for expected net worth:

Expected Net Worth = (Age × Pre-tax Annual Income) ÷ 10

  • Prodigious Accumulator of Wealth (PAW): Net worth > 2x expected
  • Average Accumulator of Wealth (AAW): Net worth ≈ expected
  • Under Accumulator of Wealth (UAW): Net worth < 0.5x expected

Example: A 45-year-old earning $120,000 should have a net worth of (45 × $120,000) ÷ 10 = $540,000.

Why Net Worth Matters More Than Income:

High Income, Low Net WorthModerate Income, High Net Worth
Doctor earning $400K with $300K in student loans, $600K mortgage, expensive lifestyleTeacher earning $65K with paid-off house, $500K in retirement accounts
Net worth: ~$200KNet worth: ~$700K
"Rich" (high income)"Wealthy" (high net worth)

How to Grow Net Worth:

  1. Increase income — Career advancement, side businesses, skill development
  2. Decrease spending — Lifestyle optimization, not deprivation
  3. Invest the difference — Compound growth in tax-advantaged accounts
  4. Reduce debt — Especially high-interest consumer debt
  5. Track monthly — What gets measured gets managed

The distinction between income and net worth is crucial: income is how fast water flows into the bucket, while net worth is how much water is in the bucket. You can have a high-flow hose (income) with a leaky bucket (spending) and end up with nothing, or a modest flow with a solid bucket and accumulate significant wealth over time.

Net Worth Example

  • 1A 40-year-old with a $350,000 home, $200,000 in retirement accounts, and $50,000 in savings, but owing $250,000 on a mortgage and $30,000 in car loans, has a net worth of $320,000 ($600,000 assets - $280,000 liabilities).
  • 2Using the Millionaire Next Door formula, a 50-year-old earning $150,000 should have a net worth of (50 × $150,000) ÷ 10 = $750,000. Having $1.5M makes them a Prodigious Accumulator of Wealth (PAW).
