How to Calculate Net Worth
What net worth means, how to calculate it, what counts as an asset or liability, and what's a good net worth by age.
The formula
Net Worth = Total Assets − Total Liabilities
Net worth is a snapshot of your financial position at a point in time. A positive number means you own more than you owe. A negative number — common early in adult life — means debts exceed assets.
What counts as an asset
Assets are things of value that you own:
Liquid assets
- Checking & savings accounts
- Money market accounts
- Cash
Investments
- Brokerage accounts
- 401(k) & IRA balances
- Stocks, ETFs, bonds
Real estate
- Home (current market value)
- Investment properties
- Land
Other
- Vehicles (current value)
- Business equity
- Collectibles, jewelry
What counts as a liability
Liabilities are debts you owe:
- —Mortgage balance (not the property value — the remaining loan)
- —Auto loans
- —Student loans
- —Credit card balances
- —Personal loans
- —Medical debt
- —Business loans
Worked example
ASSETS Checking account $8,000 Savings account $15,000 401(k) $62,000 Home (market value) $380,000 Car (trade-in value) $18,000 Total assets: $483,000 LIABILITIES Mortgage balance $295,000 Auto loan $12,000 Student loans $24,000 Credit card balance $3,200 Total liabilities: $334,200 NET WORTH = $483,000 − $334,200 = $148,800
What's a good net worth by age?
The rule of thumb from personal finance: your net worth should be roughly your age × your annual income ÷ 10. At 35 earning $70,000/year, that's $245,000. This is a rough benchmark, not a judgement.
Median US net worth by age (Federal Reserve, 2022): under 35: $39,000 · 35–44: $135,000 · 45–54: $247,000 · 55–64: $364,000 · 65–74: $410,000. The average is much higher because it's skewed by the ultra-wealthy.
Frequently asked questions
- Should I include my home in net worth?
- Yes, at current market value minus the mortgage balance. Your home equity (value minus what you owe) is a genuine asset. However, it's illiquid — you can't spend it without selling or borrowing against it. Many financial advisors track "liquid net worth" (excluding home equity and retirement accounts with early withdrawal penalties) separately as a more practical measure.
- How often should I calculate my net worth?
- Once a quarter or once a year is sufficient for most people. More frequent tracking can create anxiety around normal market fluctuations, especially for investment-heavy portfolios. The trend over years matters more than any single snapshot.
- Is a negative net worth bad?
- It depends on why. Negative net worth from student loans and a mortgage early in your career is normal and expected — these are investments in future income. Negative net worth from consumer debt (credit cards, car loans) at mid-career is a warning sign worth addressing. Track the trend: is net worth increasing year over year?
