How Net Worth Is Calculated for Family Fortunes
Family net worth is estimated by aggregating the value of publicly traded shares, private company stakes, real estate, and other assets, then subtracting known debts and liabilities. Forbes and Bloomberg update these estimates using market prices, regulatory filings, and interviews with family representatives, with changes reflecting stock movements and new investments. For example, the Walton family's net worth moves with Walmart stock, while the Mars family's wealth is tied to Mars Inc., a privately held confectionery and pet food empire.
