What Is Net Worth?
Net worth is the difference between what you own and what you owe: Net Worth = Total Assets − Total Liabilities. It's the single most useful number for measuring your overall financial health, because it captures both sides of the balance sheet — not just income or savings in isolation.
A positive net worth means your assets outweigh your debts. A negative net worth means you owe more than you own — common early in life when student loans and mortgages haven't yet been offset by accumulated savings.
What Counts as an Asset?
Assets are anything of monetary value you own:
- Liquid assets: Checking, savings, money market accounts, and cash. These are immediately accessible.
- Investment accounts: 401(k), IRA, Roth IRA, brokerage accounts, stocks, bonds, and mutual funds.
- Real estate: Use current market value, not what you paid. Check recent comparable sales or tools like Zillow for an estimate.
- Vehicles: Use current resale value (not purchase price). Cars depreciate quickly.
- Other: Business ownership, valuable collectibles, jewelry, or any other significant asset.
What Counts as a Liability?
Liabilities are any debts or financial obligations you owe:
- Mortgage balance: The remaining principal on your home loan(s), not the original amount borrowed.
- Auto loans: Outstanding balance on car financing.
- Student loans: Federal and private, combined.
- Credit card balances: Any balance you carry month-to-month (not just your credit limit).
- Personal loans, HELOCs, medical debt, and any other amounts owed.
Average Net Worth by Age
According to the Federal Reserve's Survey of Consumer Finances, here are approximate median and mean net worth figures by age group in the U.S.:
| Age Group | Median Net Worth | Mean Net Worth |
|---|---|---|
| Under 35 | $39,000 | $183,000 |
| 35–44 | $135,000 | $549,000 |
| 45–54 | $247,000 | $975,000 |
| 55–64 | $365,000 | $1,566,000 |
| 65–74 | $410,000 | $1,794,000 |
| 75+ | $335,000 | $1,624,000 |
The median is a better benchmark for most people — the mean is skewed upward by a small number of very high-net-worth households. Don't use these as a grading system; use them as rough context. What matters most is that your own net worth is trending in the right direction.
How to Grow Your Net Worth
Net worth grows when your assets increase, your liabilities decrease, or both. In practice, the fastest ways to move the needle are:
- Pay down high-interest debt first. Credit card debt at 20%+ APR destroys net worth faster than almost anything else. Eliminating it gives you a guaranteed after-tax return equal to the interest rate.
- Invest consistently. Contributions to a 401(k), IRA, or brokerage account compound over time. The earlier you start, the more time compounding has to work.
- Build home equity. Each mortgage payment shifts a portion of the principal from liability to asset. Rising home values accelerate this.
- Avoid depreciating debt. Borrowing to buy things that lose value (cars, consumer goods) increases liabilities without a matching increase in assets.
Frequently Asked Questions
Should I include my home at purchase price or market value?
Always use current market value. Your net worth reflects what you could actually sell your assets for today — not what you paid years ago. If your home has appreciated, that gain is part of your net worth even if it's unrealized.
Should I count my 401(k) before or after taxes?
Most people include pre-tax retirement accounts at their full balance, which slightly overstates true net worth since you'll owe income tax when you withdraw. For a more conservative estimate, discount traditional 401(k) and IRA balances by your expected tax rate (e.g., 20–25%). Roth accounts are after-tax, so no adjustment needed.
Is a negative net worth bad?
Not necessarily, depending on your age and the type of debt. A 25-year-old with $80,000 in student loans but a degree that will generate a high income is in a different position than someone the same age with $80,000 in credit card debt. What matters is trajectory — is your net worth improving each year?
