What net worth is measuring
Net worth is the value of total assets minus total liabilities. Assets can include cash, investments, retirement accounts, property, vehicles, and other valuable holdings. Liabilities can include mortgages, student loans, vehicle debt, credit-card balances, and other obligations that still need to be repaid.
That makes net worth different from income. A household can have a strong salary and still carry a weak balance sheet if debts remain high or assets stay illiquid. A net worth calculator is useful because it reframes the question from “What did I earn this month?” to “What position am I actually building?”
