Net worth is calculated by subtracting everything you owe from everything you own: Total Assets minus Total Liabilities. The result is a single number that represents your actual financial position — not your income, not your spending, but your true wealth at this moment.
Most people have a rough sense of their income but almost no idea what their net worth is. According to the Federal Reserve's Survey of Consumer Finances, the median net worth for Americans under 35 is approximately $39,000 — yet many in that age group assume they have essentially nothing because they focus on debt balances rather than asset values. Calculating it once a year gives you a baseline. Watching it grow gives you a goal. The number is usually more encouraging than people expect.

The Net Worth Formula
The net worth formula is the simplest equation in personal finance:
Net Worth = Total Assets - Total Liabilities
Where:
- Total Assets — the current market value of everything you own that has monetary value
- Total Liabilities — the current outstanding balance of everything you owe
- Net Worth — your financial position; positive means you own more than you owe, negative means the reverse
Worked example: 34-year-old's complete net worth calculation
Assets — list every account and item at current market value:
| Asset | Value | |---|---| | Checking account | $3,400 | | Savings account | $11,200 | | 401(k) balance | $42,800 | | Roth IRA | $18,600 | | Brokerage account | $8,750 | | Home (current market value) | $287,500 | | Car (current resale value) | $14,200 | | Personal property (estimated) | $3,500 | | Total assets | $389,950 |
Liabilities — list every outstanding balance:
| Liability | Balance owed | |---|---| | Mortgage remaining | $241,300 | | Car loan | $8,900 | | Student loans | $22,400 | | Credit card balance | $3,200 | | Total liabilities | $275,800 |
Step — Apply the formula:
Net Worth = $389,950 - $275,800 = $114,150
The result: this person has a net worth of $114,150. Despite owing $275,800 across several debts, they own enough assets — primarily their home equity — to produce a solidly positive net worth. For a 34-year-old, this is meaningfully above the $39,000 median for their age group, according to the Federal Reserve's data.
Note that retirement accounts are included at full market value. Although withdrawing them early would trigger taxes and penalties, they represent real wealth and are standard practice to include in net worth calculations.
How to Calculate Your Net Worth Step by Step
-
List all your assets with current market values. Pull balances from every financial account: checking, savings, money market, brokerage, 401(k), IRA, HSA, and any other investment accounts. For real estate, use the current estimated market value — not what you paid — from a tool like Zillow or a recent appraisal. For vehicles, use the current private-party sale value from Kelley Blue Book, not what you owe.
-
List all your liabilities with current outstanding balances. Log into every account where you carry debt: mortgage servicer, auto lender, student loan servicer, credit card portals, personal loan platforms. Write down the current payoff balance — not the original loan amount, and not the monthly payment. The payoff balance is what you would owe if you paid it off today.
-
Add up all assets. Sum every asset value into a single total. Keep financial assets (cash, investments, retirement) separate from physical assets (home, car, personal property) in your working document — this breakdown helps you analyze the composition of your wealth, not just the total.
-
Add up all liabilities. Sum every debt balance. If a debt has both a balance and accrued interest not yet billed, use the full balance including accrued interest for an accurate picture. Minimum payment amounts are irrelevant here — only the current balance owed matters.
-
Subtract total liabilities from total assets. Net worth = assets minus liabilities. A positive result means you own more than you owe. A negative result — called negative net worth — is common for recent graduates with student loans and is not a crisis, just a starting point.
-
Verify the result is plausible. A quick check: your home equity alone (home value minus mortgage balance) should be a substantial portion of your net worth if you own property. On the example above, home equity = $287,500 - $241,300 = $46,200. Combined with $84,750 in financial accounts, the $114,150 total makes sense. If your result seems wildly off, recheck that you used current market values for assets and current balances (not original loan amounts) for liabilities.
Pro tip: Calculate net worth on the same date every year — January 1st or your birthday works well. Tracking the year-over-year change matters more than any single snapshot. A net worth that grows $15,000–$30,000 per year through saving and debt paydown puts you on a strong trajectory regardless of the starting number.
What Is the Average Net Worth by Age in the US?
Average and median net worth differ significantly — a small number of very wealthy households pull the mean much higher than the median. The median is the more useful benchmark for most people.
According to the Federal Reserve's 2022 Survey of Consumer Finances:
| Age group | Median net worth | Mean net worth | |---|---|---| | Under 35 | $39,000 | $183,000 | | 35–44 | $135,600 | $549,000 | | 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 median figures are what half of Americans in each age group have above and half have below. If you are 38 with $114,150 in net worth, you are well above the median for your age group — a fact that would be invisible without doing the calculation.
A few things the averages do not show: net worth is heavily concentrated in home equity for most Americans, especially under 55. Liquid investable assets are often far lower than total net worth suggests. A person with $247,200 in net worth at age 50 may have $180,000 in home equity and only $67,200 in accessible financial assets — which looks very different for retirement planning.
Use the retirement calculator to see how your investable net worth specifically compares to what you will need at retirement, separate from home equity.
What Counts as an Asset When Calculating Net Worth?
An asset is anything with current monetary value that you own outright or have equity in. When calculating net worth, use current market value — not original purchase price, not sentimental value, not replacement cost.
Standard assets to include:
- Cash and checking accounts
- Savings and money market accounts
- Certificates of deposit (CDs)
- Brokerage and investment accounts
- 401(k), 403(b), IRA, Roth IRA, SEP IRA, HSA
- Real estate (primary home, rental properties, land)
- Vehicles (cars, boats, motorcycles at current resale value)
- Business equity (your ownership share of a business at estimated value)
- Collectibles and valuables with established markets (gold, art with appraisals)
Assets typically not included:
- Personal property of uncertain value (furniture, clothing, electronics — unless very high value)
- Life insurance cash value is sometimes included, sometimes excluded — include it if it has meaningful surrender value
- Pending income (salary owed, tax refund expected) — these are not assets until received
The most common mistake is including a car at its purchase price instead of current resale value. A car purchased for $32,000 three years ago may have a current resale value of $18,500 — a $13,500 difference that significantly affects net worth accuracy. Use Kelley Blue Book for vehicles and recent comparable sales for real estate.
How Can You Increase Your Net Worth Faster?
Net worth grows through two simultaneous levers: increasing assets and decreasing liabilities. The fastest gains come from doing both at once.
The three highest-impact actions, ranked by typical dollar effect:
1. Reduce high-interest debt aggressively. Every dollar of credit card debt eliminated at 22% APR produces an immediate 22% guaranteed return on net worth — better than almost any investment. A $5,000 credit card balance costs approximately $1,100/year in interest. Eliminating it adds $5,000 to net worth and saves $1,100 annually going forward.
2. Increase retirement account contributions. A 401(k) contribution with an employer match immediately boosts net worth by the match percentage. A 3% match on a $65,000 salary = $1,950/year in free money added directly to net worth. Beyond the match, tax-advantaged growth in retirement accounts compounds faster than taxable accounts.
3. Build home equity through extra mortgage payments. Every extra dollar paid toward mortgage principal adds directly to net worth. On a $247,500 mortgage at 7%, an extra $300/month increases net worth by $3,600/year in additional principal reduction — plus it saves interest that would otherwise reduce future net worth.
The compound interest calculator models how consistent investment contributions translate to net worth growth over 10, 20, and 30 years.
Common Mistakes to Avoid When Calculating Net Worth
-
Using purchase price instead of current market value for assets. A home bought for $210,000 that is now worth $287,500 should be listed at $287,500, not $210,000. Using original cost understates net worth and gives you a false picture of your financial position. Always use current market value.
-
Including gross asset value without subtracting the associated liability. Listing a $287,500 home as an asset without listing the $241,300 mortgage as a liability overstates net worth by $241,300. Assets and liabilities are always separate line items — the formula subtracts them at the end.
-
Forgetting small but significant accounts. Old 401(k)s from previous employers, dormant savings accounts, HSA balances, Treasury bonds — these are easy to forget and collectively can add $10,000–$50,000 to net worth. Pull your Social Security earnings statement at ssa.gov to remind yourself of every employer you have had; each may have a forgotten retirement account.
-
Counting the full value of jointly owned assets. If you own a home with a spouse and are calculating your individual net worth, include only your proportional share of both the asset value and the mortgage liability. Household net worth and individual net worth are different calculations.
-
Not recalculating annually. Net worth calculated once is trivia. Net worth tracked year over year is a financial dashboard. The year-over-year change — how much did my net worth grow this year, and why — is the number that drives better financial decisions.
Frequently Asked Questions
What is net worth and why does it matter? Net worth is the difference between everything you own and everything you owe. It matters because income is a flow — money in and out — while net worth is a stock: the accumulated result of every financial decision you have ever made. Two people earning $80,000/year can have net worths of $12,000 and $380,000 depending on their savings, debt, and investing habits over time.
What if my net worth is negative? Negative net worth — where liabilities exceed assets — is common among people under 30 with student loans and no home equity yet. It is a starting point, not a crisis. The priority is to stop taking on new high-interest debt and to begin building assets through savings and retirement contributions. Most people with negative net worth at 25 have positive net worth by 35 if they maintain consistent financial habits.
What is the difference between net worth and liquid net worth? Net worth includes all assets at current market value, including illiquid ones like real estate and retirement accounts. Liquid net worth includes only assets you could convert to cash within a few days without significant penalty — primarily checking, savings, and brokerage accounts. Liquid net worth is the more relevant number for emergency planning; total net worth is the more relevant number for retirement planning and wealth measurement.
How much should my net worth increase each year? A sustainable target is to increase net worth by 10–15% of your gross annual income per year through a combination of savings, debt paydown, and investment growth. On a $65,000 salary, that is $6,500–$9,750 in net worth growth per year from your own actions — plus any investment returns on existing assets. In a year with strong market returns, total net worth growth often significantly exceeds this baseline.
When should I calculate my net worth? Calculate it once when you first get serious about your finances — this is your baseline. Then recalculate annually on the same date to track progress. Calculate it additionally before major financial decisions: buying a home (to evaluate down payment capacity), applying for a large loan (lenders sometimes ask), or changing jobs (to understand your financial cushion during a transition). The investment calculator can project how your current net worth grows at different savings rates.
These figures are estimates for planning purposes. Asset values fluctuate and liability balances change with each payment. Consult a licensed financial advisor for a comprehensive financial plan.
