How to Calculate Net Worth
The net worth formula is simple: Net Worth = Total Assets - Total Liabilities. Assets include every item of value you own, from bank account balances to real estate to retirement funds. Liabilities include every dollar you owe, from your mortgage to credit card balances. The difference between these two numbers is your net worth. Sam Okafor, a realtor in Pinewood Falls, reviews his net worth each quarter to track how his real estate holdings and investment accounts are performing relative to his mortgage and business expenses.
A positive net worth means you own more than you owe. A negative net worth means your debts exceed your assets, which is common among recent graduates carrying student loans or young homeowners who recently made a down payment. The key metric is not the absolute number but the direction: your net worth should generally increase over time as you pay down debt, save, and benefit from investment growth. Even small monthly contributions to savings and retirement accounts compound significantly over decades.
When gathering your numbers, use current balances rather than estimates. Log in to your bank, brokerage, and loan accounts to get exact figures. For real estate, use a recent appraisal or comparable sales in your area rather than your original purchase price. For vehicles, check Kelley Blue Book or a similar tool for current resale value. Accuracy makes your net worth calculation meaningful for tracking progress over time.
Average Net Worth by Age
The Federal Reserve's Survey of Consumer Finances (SCF) is the most authoritative source for household wealth data in the United States. The survey is conducted every three years, and the most recent data is from 2022. The table below shows both median and mean net worth by age group. Median is the more useful comparison because a small number of very wealthy households pull the mean (average) much higher.
| Age Group | Median Net Worth | Mean Net Worth |
|---|---|---|
| Under 35 | $39,000 | $183,500 |
| 35 to 44 | $135,600 | $549,600 |
| 45 to 54 | $247,200 | $975,800 |
| 55 to 64 | $364,500 | $1,566,900 |
| 65 to 74 | $409,900 | $1,794,600 |
| 75 and older | $335,600 | $1,624,100 |

Net worth typically peaks between ages 65 and 74, then declines slightly as retirees draw down savings. The gap between median and mean illustrates how wealth concentration affects averages. For the under-35 group, the median is $39,000 while the mean is $183,500, meaning a relatively small number of young high earners or inheritors pull the average up nearly five times the midpoint. Tom Brewer, a retired engineer in Pinewood Falls, notes that his net worth peaked around age 70 and has remained stable since, thanks to a balanced portfolio and paid-off mortgage.
What to Include in Your Assets
A complete asset inventory should cover six main categories. Cash and bank accounts include checking, savings, money market accounts, and certificates of deposit. Investment accounts cover taxable brokerage accounts holding stocks, bonds, mutual funds, and ETFs. Retirement accounts include employer plans (401k, 403b, 457), individual retirement accounts (traditional IRA and Roth IRA), and pensions with a lump-sum value. For retirement accounts, use the current account balance even though you may owe taxes on withdrawals. The SEC's investor tools can help you understand account types.
Real estate includes your primary residence, rental properties, and vacant land at current market value. Sam Okafor recommends using the most recent comparable sales within a half mile, adjusted for square footage and condition, for the most realistic estimate. Vehicles include cars, trucks, motorcycles, and recreational vehicles at their current resale value, not what you paid. Finally, other assets can include business ownership equity, life insurance cash value, valuable collectibles, and intellectual property. Do not include everyday personal property like furniture, clothing, or electronics unless individual items have documented resale value above a few thousand dollars.
Common Liabilities to Track
Liabilities fall into two broad categories: secured and unsecured debt. Secured debts are backed by an asset that the lender can repossess if you default. Mortgages (secured by your home) and auto loans (secured by the vehicle) are the most common. Unsecured debts include credit card balances, personal loans, medical bills, and student loans. The Consumer Financial Protection Bureau (CFPB) provides resources for understanding and managing each type.
When listing liabilities, use the current outstanding balance, not the original loan amount. A mortgage taken out for $300,000 five years ago may have a current balance of $270,000. That $270,000 is the figure to enter. Include all debts: it is tempting to leave off small credit card balances or a personal loan from a family member, but an accurate net worth requires listing every obligation. If you owe taxes to the IRS or have outstanding medical bills in collections, those count as liabilities too. The goal is a complete, honest picture of your financial position.
How to Increase Your Net Worth
Net worth grows through two levers: increasing assets and decreasing liabilities. On the asset side, the most effective strategies are maximizing retirement contributions (especially with an employer match), building an emergency fund of three to six months of expenses, and investing consistently in low-cost index funds. The SEC recommends starting early because compound growth accelerates over time. A $500 monthly investment at 7% annual return grows to approximately $566,000 over 30 years.
On the liability side, prioritize paying off high-interest debt first. Credit card interest rates often exceed 20% annually, which erodes wealth faster than most investments can build it. The avalanche method (paying minimums on all debts while directing extra cash to the highest-rate balance) saves the most in total interest. Once high-interest debt is eliminated, redirect those payments to savings and investments. Tom Brewer started tracking his net worth at age 35 and credits the habit with keeping him focused on long-term goals rather than short-term spending.
Homeownership is a powerful net worth builder for most households because each mortgage payment increases your equity while the property typically appreciates in value. However, the house itself does not generate liquid income, so balance real estate equity with accessible savings and investments. A diversified approach that combines home equity, retirement accounts, and taxable investments provides both growth and flexibility. Use the compound interest calculator to model how regular contributions to investment accounts grow over 10, 20, or 30 years.
Net Worth Benchmarks
Beyond the age-based averages from the Federal Reserve, several practical benchmarks can help you evaluate your financial position. A widely cited guideline from The Millionaire Next Door by Thomas Stanley suggests your expected net worth should equal your annual pre-tax income multiplied by your age, divided by 10. For example, a 40-year-old earning $80,000 would have an expected net worth of $320,000 by this formula.
| Benchmark | Target | Source |
|---|---|---|
| Emergency fund | 3 to 6 months of expenses in cash | CFPB |
| Retirement savings by 30 | 1x annual salary | Fidelity |
| Retirement savings by 40 | 3x annual salary | Fidelity |
| Retirement savings by 50 | 6x annual salary | Fidelity |
| Retirement savings by 60 | 8x annual salary | Fidelity |
| Retirement savings by 67 | 10x annual salary | Fidelity |
| Debt-to-income ratio | Below 36% of gross income | CFPB |

These benchmarks are guidelines, not rigid rules. A household with a paid-off home and modest retirement savings may be in a stronger position than one with a larger 401k balance but significant credit card debt. Context matters. Use the benchmarks as directional targets and focus on consistent improvement rather than hitting exact numbers at specific ages.
