How Is Net Worth Calculated?

Net worth is calculated with one formula: total assets minus total liabilities. Add up the value of everything you own — cash, retirement accounts, your home, your car — then subtract everything you owe, such as your mortgage and loans. The number left over is your net worth. It is the single clearest snapshot of your financial position, and it takes about ten minutes to build. Here is exactly what goes on each side of the ledger.

The Formula

Every net-worth calculation reduces to the same subtraction:

Net Worth = Total Assets − Total Liabilities

Assets are everything you own that has value. Liabilities are everything you owe. Subtract one from the other and you have your net worth — a positive number if you own more than you owe, negative if the reverse.

What Counts as an Asset

Add up the current value of each of these — use market value, not what you originally paid:

• Cash and checking, savings, and money market accounts
• Retirement accounts — 401(k), 403(b), IRA, Roth IRA — at their current balance
• Taxable brokerage and investment accounts
• Your home’s current market value
• Vehicles at their resale value
• Business ownership or equity
• Other valuables you could realistically sell (rental property, collectibles)

What Counts as a Liability

These are your debts — the full outstanding balance you still owe:

• Mortgage balance
• Student loans
• Auto loans
• Credit card balances
• Personal loans and any other outstanding debt

The Two Questions Everyone Asks

Do I include my house? Yes — but on both sides. Count the home at its market value as an asset, and count the remaining mortgage as a liability. The gap between them, your home equity, is the part that actually lifts your net worth. If your $400,000 home carries a $250,000 mortgage, it adds $150,000, not $400,000.

Do I include my 401(k)? Yes — retirement accounts count at their current balance, even though you cannot spend them freely yet. This is where liquid net worth comes in.

Total vs Liquid Net Worth

Total net worth counts every asset. Liquid net worth counts only what you could turn into cash quickly without a big penalty or a sale — so it strips out home equity and, usually, retirement accounts. It is the better measure of how much cushion you actually have if income stops. If most of your net worth is locked in a house and a 401(k), your total number can look healthy while your liquid number is thin — which is exactly why a separate emergency fund matters.

Median Net Worth by Age

For a reference point, the Federal Reserve’s Survey of Consumer Finances tracks family net worth across the country. These are the 2022 median figures — half of families in each age group have more, half have less:

Source: Federal Reserve, Changes in U.S. Family Finances from 2019 to 2022 (Survey of Consumer Finances). The overall median family net worth was $192,900 and the mean was $1,063,700 — the mean is far higher because a small number of very wealthy families pull the average up.

Why the Trend Matters More Than the Number

A single net-worth figure is a snapshot; the direction it moves is the real signal. Two forces push it up: paying down liabilities and letting assets compound. The second is why net worth tends to accelerate once savings gain momentum — the same doubling math in our Rule of 72 explainer is what makes later decades pull ahead. Recalculating once a quarter is enough to see the trend.

Net worth is also downstream of income and how much of it you keep. If you are trying to raise your savings rate, start from what actually lands in your account — our sister site walks through that in Gross Pay vs Net Pay. From there, a retirement target gives the number a destination — see How Much Do I Need to Retire?
