Net worth: the one number that actually tracks progress
Net worth is one subtraction: everything you own, minus everything you owe. It doesn't care how much you earn or how big your house is — only what's left once the debts are paid off. That makes it the closest thing personal finance has to a single scoreboard.
The formula
Net worth = assets − liabilities. Assets are what you own with resale or cash value — a home, retirement accounts, cash, a car. Liabilities are what you owe against them — a mortgage, a car loan, credit-card balances, student loans.
A real example: mid-career household
Take a household with a home worth $420,000, $185,000 in retirement accounts, $22,000 in cash savings and a car worth $18,000.
- Total assets:
420,000 + 185,000 + 22,000 + 18,000 = $645,000.
Against that, a $310,000 mortgage balance, a $9,500 car loan and $3,200 in credit-card debt.
- Total liabilities:
310,000 + 9,500 + 3,200 = $322,700. - Net worth:
645,000 − 322,700 = $322,300.
A real example: recent graduate
Now a household just starting out: $4,500 in cash, an $8,000 car and $2,200 in a retirement account started at a first job.
- Total assets:
4,500 + 8,000 + 2,200 = $14,700.
Against $32,000 in student loans and $1,800 on a credit card.
- Total liabilities:
32,000 + 1,800 = $33,800. - Net worth:
14,700 − 33,800 = −$19,100.
A negative net worth right out of school is common, not a crisis — it just means the debts (mostly student loans, which bought future earning power) currently outweigh what's accumulated in assets. The number is only useful as a trend, and the trend for most graduates runs one direction: up.
The number that actually matters: the trend
Go back to the mid-career household a year later. They put an extra $12,000 toward the mortgage principal, their retirement account grew by $20,000 from contributions and market gains, cash stayed flat, and the car — a depreciating asset — lost $3,000 in value.
- New assets:
420,000 + (185,000 + 20,000) + 22,000 + (18,000 − 3,000) = $662,000. - New liabilities:
(310,000 − 12,000) + 9,500 + 3,200 = $310,700. - New net worth:
662,000 − 310,700 = $351,300.
That's a gain of 351,300 − 322,300 = $29,000 in a single year, from a mix of paying down debt, retirement growth and one asset quietly losing value in the background. No single line item tells that whole story on its own — the net figure does.
What counts as an asset (and what doesn't)
Stick to things with real resale or cash value: bank balances, investment and retirement accounts, a home at a realistic market estimate, vehicles at what they'd actually sell for. Skip furniture, electronics and other possessions that don't hold meaningful resale value — including them just inflates the number without changing your actual financial position.
What this doesn't capture
Net worth is a snapshot, not a cash-flow statement. A household can have a large net worth and still struggle month to month if most of it is tied up in a home or retirement account that can't easily be spent. It also says nothing about income stability or debt structure — two households with identical net worth can be in very different financial positions depending on how that money is locked up.
