Net Worth

Net worth — total assets minus total liabilities — is the single most comprehensive measure of financial health available, and it’s the one that high earners are most likely to be tracking inaccurately. Common errors include overvaluing illiquid assets, ignoring deferred tax liabilities on retirement accounts, including assets that can’t realistically be converted to cash, and failing to update values for market changes in real estate and investment portfolios. A correctly calculated net worth is the foundation for every financial plan worth building on.

Assets worth including at realistic values: liquid investment accounts (taxable brokerage, checking, savings) at market value; tax-advantaged accounts (401k, IRA, HSA) at market value but with a mental note that traditional account balances carry an embedded tax liability of 20–37% on eventual withdrawal; real estate at estimated current market value minus selling costs (typically 6–8% of value); and business interests at a conservative valuation, which for private businesses may be highly uncertain. Assets often incorrectly included: personal property (cars, jewelry, furniture), which depreciate and are illiquid; insurance cash value, which has surrender charges and policy-specific exit costs.

Benchmarking net worth by age provides useful context. The often-cited Thomas Stanley research from “The Millionaire Next Door” produces a target of: multiply age by gross annual income, divide by 10. A 45-year-old earning $400,000 has a target net worth of $1.8 million to be considered on track by this measure. Federal Reserve Survey of Consumer Finances data shows median net worth for 45–54 year olds at approximately $250,000, with the 90th percentile around $1.9 million — giving a realistic peer benchmark for different wealth levels.

Building net worth systematically requires the tax efficiency covered throughout the Tax & Wealth pillar — particularly retirement accounts, capital gains management, and deductions — combined with the income optimization strategies in the Income Reality pillar. Net worth tracking provides the scoreboard that makes those strategies legible over time.
