What is net worth — and why does it matter?
Net worth is the single most important number in personal finance. It is the sum of everything you own (your assets) minus everything you owe (your liabilities). Unlike income — which tells you how much money flows in each month — net worth tells you where you actually stand financially at a given moment in time.
A high income with no net worth growth means money is flowing out as fast as it comes in. A modest income with steadily growing net worth means wealth is being built. Net worth is the score; income is just one of the inputs.
How to calculate your net worth
The formula is simple: Net Worth = Total Assets − Total Liabilities.
What counts as an asset?
- Cash and bank accounts — checking, savings, money market accounts, CDs
- Investment accounts — brokerage accounts, stocks, ETFs, mutual funds, bonds
- Retirement accounts — 401(k), 403(b), IRA, Roth IRA, pension present value
- Home and property value — the current market value of your home(s) and any other property. Enter the mortgage separately under liabilities; the calculator subtracts it for you
- Vehicles — current Kelley Blue Book or NADA value, not the purchase price
- Business equity — your ownership stake in any business you own
- Other valuables — jewelry, art, collectibles, cryptocurrency (at current market value)
What counts as a liability?
- Mortgage balance — the remaining principal on your home loan(s)
- Auto loans — remaining balance on car financing
- Credit card debt — all outstanding balances across all cards
- Student loans — federal and private loan balances
- Personal loans — bank loans, family loans, medical debt on payment plans
- HELOC or home equity loan — outstanding balance
Average net worth by age in the United States
The Federal Reserve publishes the Survey of Consumer Finances (SCF) every three years, providing the most authoritative data on US household wealth. The 2022 SCF shows (in 2022 dollars; Federal Reserve, “Changes in U.S. Family Finances from 2019 to 2022”, Table 2):
| Age group | Median net worth | Mean net worth |
|---|---|---|
| Under 35 | $39,000 | $183,500 |
| 35–44 | $135,600 | $549,600 |
| 45–54 | $247,200 | $975,800 |
| 55–64 | $364,500 | $1,566,900 |
| 65–74 | $409,900 | $1,794,600 |
| 75+ | $335,600 | $1,624,100 |
The gap between median and mean is large because a small number of ultra-high-net-worth households pull the mean upward. The median is the more useful benchmark — it tells you what the person in the middle of the distribution looks like, not the average distorted by billionaires.
How to increase your net worth
There are only two levers: increase your assets or decrease your liabilities (ideally both simultaneously). The most effective actions, roughly in order of impact:
- Eliminate high-interest debt first. Credit card debt at 20% APR is a guaranteed 20% return when paid off — better than almost any investment. Pay the minimum on every debt and put every spare dollar toward the highest rate first.
- Increase your savings rate. Every dollar not spent is a dollar added to net worth. Even moving from a 5% to a 15% savings rate has a dramatic compound effect over 10–20 years.
- Maximise tax-advantaged accounts. 401(k) employer match is an instant 50–100% return. After that, max your IRA ($7,500/yr in 2026). These accounts grow tax-deferred or tax-free, accelerating net worth compounding.
- Invest consistently in low-cost index funds. Time in the market beats timing the market. A low-cost S&P 500 index fund has returned ~10% annualised over the long run.
- Build home equity strategically. Making extra mortgage principal payments reduces liabilities directly. Refinancing to a lower rate saves interest that can be redirected to investments.
Track your net worth over time
A single net worth calculation is a snapshot. The real value comes from tracking it monthly or quarterly and watching the trend. Most people find that the act of measuring net worth regularly motivates better financial decisions.
Consider calculating your net worth at the same time each quarter — for example, on the first Sunday of January, April, July, and October. Over a year, you will have four data points that show whether you are moving in the right direction.
Net worth and retirement readiness
Net worth is the foundation of retirement planning. While income measures your earning power, net worth measures your financial independence. The relationship between net worth and retirement readiness is direct: your net worth (excluding your primary residence) multiplied by a safe withdrawal rate (typically 4%) gives you your sustainable annual income from savings.
Example: $800,000 in investable net worth × 4% = $32,000/year from portfolio withdrawals. Add Social Security (about $24,852/year, the average for retired workers in 2026) and your estimated retirement income is $56,852/year. If your expected expenses are $50,000/year, you are on track. If they are $70,000/year, you have a gap to close.
This connection between net worth and retirement income is why tracking net worth regularly is one of the most important habits in personal finance. Every dollar added to net worth translates directly to future financial security.
Common mistakes when calculating net worth
Getting an accurate net worth requires honest accounting. The most common errors that lead people to overestimate or underestimate their true position:
- Using purchase price instead of current market value. Your car is not worth what you paid for it — it is worth what a buyer would pay today. Use Kelley Blue Book (kbb.com) for vehicles, Zillow or a recent appraisal for real estate, and current brokerage statements for investments.
- Forgetting liabilities. Outstanding medical bills, owed taxes, personal loans from family, and buy-now-pay-later balances are all liabilities. If you owe it, it counts.
- Overvaluing illiquid assets. A small business, collectibles, or art may have theoretical value but cannot be converted to cash quickly or without significant discount. Track these separately from liquid assets.
- Including assets you cannot access. A pension that will not pay out for 20 years has present value, but it is not the same as $500,000 in a brokerage account. Some planners exclude pensions from net worth and instead model them as future income.
- Not updating regularly. A net worth calculation from two years ago is stale. Investment values, mortgage balances, and debt levels change constantly. Quarterly updates keep the picture accurate.
Liquid net worth vs total net worth
Total net worth includes everything — home equity, retirement accounts, vehicles, and personal property. Liquid net worth strips out assets that cannot be quickly converted to cash without penalty or significant loss.
The distinction matters because a high total net worth with low liquidity can leave you vulnerable. A homeowner with $800,000 in home equity and $20,000 in the bank has a strong total net worth but very little financial flexibility for emergencies, job loss, or opportunities.
For practical financial planning, track both numbers. Total net worth measures long-term wealth accumulation. Liquid net worth — cash, brokerage accounts, and savings — measures financial resilience and flexibility.
Net worth milestones and what they mean
While there is no universal net worth target, several milestones serve as useful markers in wealth building:
- $0 (positive net worth): You own more than you owe. For many people emerging from student debt, this is the first meaningful milestone.
- $100,000: Charlie Munger (Warren Buffett's partner) famously called the first $100,000 the hardest — after that, compounding does increasingly heavy lifting.
- 1x annual salary: Fidelity recommends having 1x your salary saved by age 30, 3x by 40, 6x by 50, 8x by 60, and 10x by 67 for a comfortable retirement.
- $1,000,000: The millionaire milestone. In real terms, adjusted for inflation, this provides roughly $40,000/year under the 4% withdrawal rule — enough to cover basic expenses but not a luxurious retirement for most Americans.
Tools for tracking net worth
Beyond this calculator, several free tools can help you track net worth over time by automatically pulling balances from your financial accounts:
- Empower (formerly Personal Capital): Free net worth tracker that connects to bank, brokerage, and retirement accounts. Automatically updates balances and shows historical net worth trends with charts.
- Mint / Credit Karma: Free budgeting apps that include a net worth view. Less focused on net worth than Empower, but useful if you already use them for budgeting.
- Spreadsheet: A simple Google Sheet or Excel template with monthly rows for each asset and liability. Manual but fully customisable. Many people prefer this for the forced engagement of entering numbers by hand — the act of manual entry builds awareness and accountability.
Frequently asked questions
What is net worth?
Net worth is total assets minus total liabilities. It is the foundational measure of financial health — your true position after all debts are accounted for.
What is a good net worth by age?
Using the Federal Reserve SCF 2022 data, the median US net worth is $39,000 for under-35, $135,600 for 35–44, $247,200 for 45–54, $364,500 for 55–64, $409,900 for 65–74, and $335,600 for 75 and over (in 2022 dollars). These are medians — half of Americans in each group are above, half below.
Should I include my primary home in net worth?
Yes — home equity (market value minus mortgage) is a real asset. In this calculator, enter the home's market value as an asset and the mortgage as a debt, and the difference counts towards your net worth. However, because your home is illiquid, many planners also calculate "liquid net worth" (excluding real estate) to assess the wealth you could actually access quickly.
What if my net worth is negative?
Negative net worth is common among younger adults with student loans and early-stage mortgages. It is a starting point, not a verdict. Focus on the trend: is your net worth improving each quarter? That is more important than the absolute number today.
How often should I calculate my net worth?
Quarterly is the sweet spot for most people. Monthly can be useful when actively paying down debt or building savings. Annual is the minimum — at least once a year, take stock of where you stand.
