Net worth represents the most comprehensive measure of financial health, calculated as total assets minus total liabilities. Assets include liquid assets (cash, savings), investments (retirement accounts, brokerage), and personal property (home, vehicles). Liabilities include all debts (mortgage, auto loans, student loans, credit cards).

Median net worth for Americans under 35 is approximately $14,000, while those aged 55-64 have median net worth around $187,000. Financial planners suggest accumulating 10-12 times annual income by retirement age. Strategies for increasing net worth focus on growing assets (maximize retirement contributions, maintain emergency funds, invest consistently) and reducing liabilities (accelerate debt payoff, avoid new consumer debt).
