Net worth is the one number that summarizes everything
Net worth = total assets − total liabilities. Example: $12,000 cash + $65,000 investments + $350,000 home + $18,000 vehicles + $5,000 other = $450,000 in assets; subtract a $240,000 mortgage, $14,000 in loans, and $3,000 on cards, and net worth is $193,000. Income tells you how fast money flows in; net worth tells you how much has actually stuck.
Why the "excluding home and vehicles" line matters
Home equity is real wealth, but you can't spend it without selling, borrowing, or moving, and cars lose value every year. Stripping them out shows your liquid, income-producing net worth — the number that funds retirement. A household with a $193,000 net worth that is $110,000 home equity and $18,000 of cars has $60,000 doing financial work; tracking both figures keeps the picture honest.
Benchmarks and how to move the number
One popular benchmark (from "The Millionaire Next Door") says expected net worth ≈ age × pre-tax income ÷ 10. The trend matters far more than any single reading: recompute quarterly and watch the direction. Net worth rises exactly three ways — spend less than you earn, pay down debt, and let invested assets compound — and every dollar of extra mortgage or card payment moves it just as surely as a market gain.
How to use this calculator
List every asset at a realistic value: cash and savings at face value, investment and retirement accounts at current balances, your home at a conservative quick-sale price, and vehicles at resale (not purchase) value. Then list every debt — mortgage, student loans, auto loans, and credit card balances. The calculator returns your net worth plus a breakdown, including home equity and a net-worth-excluding-house-and-cars figure that shows your liquid, wealth-building assets. Don't inflate the number with furniture or optimistic home values; the point is an honest baseline. Recompute quarterly and save each snapshot — the direction of the trend over a year or two tells you far more than any single reading ever could.
