What Is Net Worth?
Net worth is the total value of what a person owns minus what they owe. It gives a single figure showing financial position at one moment in time, and it is often prepared as a personal balance sheet. The core idea is a simple subtraction:
Net Worth = Total Assets − Total Liabilities
Assets are things with economic value, such as cash, savings accounts, investment portfolios, retirement accounts, real estate, and vehicles. Liabilities are debts, such as mortgages, car loans, student loans, and credit card balances. When assets exceed liabilities, net worth is positive. When debts exceed assets, net worth is negative, which can happen early in a career or after large borrowing.
How Net Worth Is Calculated
To calculate net worth, list every asset at its current estimated value, then list every debt at the amount still owed. Some items are easy to value, such as a checking account balance. Others require estimates, such as a home's value or a stake in a private business. Using market value where possible keeps the figure more consistent over time. Assets that cannot be sold quickly, such as real estate, are called illiquid assets, and their estimated values can change considerably depending on the method used.
As a hypothetical example, a person with $150,000 in total assets and $100,000 in total liabilities has a net worth of $50,000. If that person uses $10,000 of cash to pay down a loan, assets and liabilities both fall by $10,000, so net worth stays the same.
Why Net Worth Matters to Investors
Tracking net worth over time shows whether financial position is growing, shrinking, or holding steady. Because it combines assets and debts, it can reveal changes that income alone does not, such as rising borrowing.
Net worth has limits, however. It does not measure cash flow or income, and a high net worth may be concentrated in assets that are hard to spend. Market swings can change asset values quickly, so the figure can move even when saving and spending habits stay the same. For companies, the equivalent measure is shareholders' equity.
