Total assets minus total liabilities; the clearest snapshot of financial health.
Net worth is your total assets minus total liabilities—the value you'd have left if you sold everything and paid all debts. It's the best single measure of financial health and wealth. For example, if you own a home worth $300,000 with a $200,000 mortgage, $50,000 in investments, $15,000 in car value, and have $5,000 in credit card debt, your net worth is ($300,000 + $50,000 + $15,000) – ($200,000 + $5,000) = $160,000. Tracking net worth over time reveals financial progress. Increasing net worth requires either increasing assets or decreasing liabilities (or both). Financial independence typically targets a net worth high enough that investment returns cover living expenses. Net worth can be negative if liabilities exceed assets; this is common for recent college graduates with student loans.
Net worth follows the fundamental balance-sheet identity used in U.S. accounting standards and Federal Reserve household-finance methodology: Net Worth = Total Assets − Total Liabilities. To compute it correctly, you list every asset at its current fair-market value (NOT purchase price) and every liability at its current outstanding balance. Assets typically include: cash and bank balances, retirement accounts (401k, IRA, pension cash value), brokerage accounts, real-estate equity (home market value minus mortgage balance is captured by listing both sides separately), vehicles (using KBB or Edmunds estimate, not original price), and other valuables only if you would realistically sell them. Liabilities include: mortgage principal balance, student loans, auto loans, credit-card balances, personal loans, and any other outstanding debt. The Federal Reserve Survey of Consumer Finances (SCF) is the authoritative benchmark for U.S. household net worth — it reports medians by age, income, race, and education so individuals can compare themselves to peers. Common mistakes: (1) using purchase price instead of current market value (especially for cars, which lose 20-30% in year one), (2) double-counting home equity (listing both the home value AND the equity figure), (3) including non-vested 401k employer matches or unexercised stock options at intrinsic value, (4) ignoring liabilities by netting them against the corresponding asset (this hides leverage), (5) including future Social Security or pension income streams — those are flow, not stock, so they don't belong on the balance sheet. Net worth can be NEGATIVE — this is normal for recent graduates with student debt and no equity. The trajectory matters more than the absolute number; quarterly tracking shows whether the trend line is improving.
Sum every asset at current market value: cash, bank balances, retirement and brokerage accounts, home value, vehicle value (use KBB), and any other property you would realistically sell. Then sum every liability: mortgage balance, student loans, auto loans, credit-card balances, personal loans. Subtract liabilities from assets. The result is your net worth. The Federal Reserve Survey of Consumer Finances uses the same balance-sheet identity to compute U.S. household statistics; it's the standard methodology.
The Federal Reserve's Survey of Consumer Finances reports U.S. median household net worth by age group. The medians vary by survey year, but the pattern is consistent: net worth typically rises through working years, peaks around retirement age, and declines slowly thereafter. A common benchmark in financial-planning literature is the Stanley/Danko "expected net worth" formula: age × pre-tax income ÷ 10. Hitting double that number is considered "prodigious accumulator" status. These are rules of thumb, not advice — actual targets depend on cost of living, savings rate, and risk tolerance.
Yes — list the home's current market value as an asset (use Zillow Zestimate, Redfin estimate, or a recent appraisal) and the outstanding mortgage balance as a liability. The DIFFERENCE between those two is your "home equity," but list them separately on your balance sheet so the leverage is visible. Some financial planners prefer a "liquid net worth" view that excludes primary-residence equity because you have to live somewhere — but for the full picture, the Federal Reserve methodology includes it.
Net worth includes ALL assets (home equity, retirement accounts, vehicles). Liquid net worth only counts assets you could convert to cash within ~30 days without significant penalty: checking and savings accounts, taxable brokerage holdings, money-market funds. It excludes home equity (requires sale or HELOC), retirement accounts (early-withdrawal penalties plus tax before age 59½), and vehicles (needed for daily life). Liquid net worth answers "what could I tap right now in an emergency"; net worth answers "what am I worth in total."
Most personal-finance literature suggests monthly or quarterly. Monthly captures bonus deposits, paydown progress, and lets you spot lifestyle creep early. Quarterly smooths out market noise (a stock-market correction can drop net worth 10-20% in a month without changing anything fundamental). The Federal Reserve itself publishes household net-worth aggregates quarterly via the Z.1 Financial Accounts release. Pick a cadence you'll actually maintain — a consistent annual snapshot beats an enthusiastic monthly start that you abandon after six months.
Yes, and it's common at certain life stages. Recent graduates with student loans, no savings, and no home equity typically have negative net worth. Households that just took on a large mortgage in a high-down-payment market may also be temporarily negative when closing costs and moving expenses are included. Negative net worth is not a moral failing — it's a stock-vs-flow problem. The fix is improving cash flow (higher savings rate) so liabilities pay down and assets accumulate. The trend line matters more than the current absolute value.
