To calculate your net worth, add up the current value of everything you own, add up the current balance of everything you owe, and subtract the second number from the first. The result is a snapshot of your financial position on that day. A positive number means your assets outweigh your debts; a negative number means the reverse. Neither is permanent, and the point of running the formula is to see which way you’re heading over time.
Because balances and market values shift constantly, pick a single date and use it consistently for every line. Mixing a checking balance from Monday with an investment balance from Friday introduces error for no reason. Quarterly or annual is enough for most people.
List Your Assets
Assets are everything you own that holds monetary value. Working through the categories below in order keeps you from missing anything:
- Cash and near-cash: checking, savings, money market accounts, and certificates of deposit.
- Investment accounts: brokerage holdings in stocks, bonds, mutual funds, and ETFs.
- Retirement accounts: 401(k) plans under Internal Revenue Code Section 401 and Individual Retirement Accounts under Section 408.1Office of the Law Revision Counsel. 26 USC 401 – Qualified Pension, Profit-Sharing, and Stock Bonus Plans2Office of the Law Revision Counsel. 26 USC 408 – Individual Retirement Accounts
- Real estate: primary home, rentals, vacation homes, and undeveloped land.
- Personal property: vehicles, jewelry, art, antiques, and high-value collectibles.
- Permanent life insurance at its cash surrender value, meaning what you’d receive if you canceled the policy today after surrender fees. Term policies have no cash value and don’t appear.
- Digital assets: cryptocurrency and tokens, valued in U.S. dollars as of your calculation date. The IRS treats these as property.3Internal Revenue Service. Frequently Asked Questions on Digital Asset Transactions
- Business interests: any private ownership stake.
Pull the supporting documents together as you go: bank statements, brokerage reports, deeds, insurance summaries, and wallet balances. Each one anchors both ownership and the exact figure for your chosen date.
Put a Value on Each Non-Cash Asset
Cash speaks for itself. Everything else needs a current value, and the standard used across tax law and financial planning is fair market value: the price a knowledgeable, willing buyer would pay a knowledgeable, willing seller when neither is under pressure.4Internal Revenue Service. Publication 561, Determining the Value of Donated Property Applied to each asset type it looks a little different.
Investment and Retirement Accounts
Use the market value shown on your brokerage or plan statement as of your chosen date. Prices publish throughout the trading day, so a personal calculation doesn’t need anything more complicated. Formal tax valuations use the average of the day’s highest and lowest quoted selling prices rather than the closing price.4Internal Revenue Service. Publication 561, Determining the Value of Donated Property
Real Estate
A professional appraisal produces the most defensible number: the appraiser inspects the property and compares it against recent local sales. Because a single-family appraisal typically costs several hundred dollars, most people rely on online estimates between updates and save the formal appraisal for refinancing or estate planning.
Vehicles and Personal Property
Vehicles are valued through standardized pricing guides that factor in mileage, condition, and local demand. Jewelry, household goods, and collectibles are valued at what they’d realistically sell for today, not what you paid. A ring bought for $5,000 may resell for $2,000; a guitar bought for $500 may now be worth $3,000. Current resale potential is the right measure in either direction.
Business Interests
Valuing a private business is harder because no public market quotes a price. For a personal net worth estimate, use the business’s book value, which is the assets on the balance sheet minus its liabilities. For a formal valuation tied to a divorce, an estate, or a sale, a certified business appraiser applies asset-based, income-based, or market-based methods in detail.
Digital Assets
Widely traded cryptocurrency is easy: check the fair market value in U.S. dollars on a major exchange on your calculation date.3Internal Revenue Service.

Adjust Traditional Retirement Balances for Tax
A $500,000 balance in a traditional 401(k) is not the same as $500,000 in a savings account. Every dollar you withdraw from a traditional 401(k) or traditional IRA is taxed as ordinary income, so the raw balance overstates spendable wealth.
A simple adjustment is to multiply the balance by one minus your expected marginal tax rate in retirement. If you expect to be in the 22 percent federal bracket, a $500,000 traditional IRA is worth roughly $390,000 after federal tax. State income tax, where it applies, would reduce it further.
Roth IRAs and Roth 401(k)s work differently. Contributions were taxed on the way in, so qualified withdrawals come out tax-free, and the statement balance already represents spendable wealth. If you hold both traditional and Roth accounts, apply the tax discount only to the traditional side. The adjustment isn’t essential for a casual check-in, but it matters when you’re comparing your position against a retirement target.
List Your Liabilities
Liabilities are every financial obligation you’re legally required to repay. The main split is between debts backed by specific property and debts that aren’t.
Secured debts are tied to collateral the lender can seize if you stop paying. Mortgages are secured by the home; auto loans by the vehicle. Home equity loans and lines of credit belong here too.
Unsecured debts carry no collateral. Credit card balances, student loans, medical bills, and personal loans are the common examples.
Contingent liabilities cover debts you’ve co-signed or personally guaranteed for someone else. They aren’t your current obligation, but they become yours if the primary borrower defaults. For a formal financial statement, include the full outstanding balance. For a personal check-in, noting the amount separately gives you a clearer risk picture without treating a theoretical debt as certain.
Use the Current Payoff Balance
For each debt, use the current payoff balance from the lender, not the original loan amount and not the sum of remaining monthly payments. The payoff figure reflects what you actually owe today, including interest accrued since your last payment. Interest on most loans accrues daily, so a mortgage payoff quoted on the 15th will be slightly higher than the balance printed on the statement from the 1st. For precision, request payoff quotes dated the same day you value your assets.
Individual Versus Household Numbers
Net worth measures what belongs to you, which gets complicated when assets are shared. How much of a jointly held asset counts toward your personal net worth depends on how it’s legally owned.
If you and another person hold an asset as joint tenants with equal shares, your calculation includes half its value and half the associated debt. For married couples, the rules depend on the state. In community property states, most assets acquired during the marriage are presumed to be owned equally regardless of whose name is on the title. In equitable distribution states, ownership during the marriage generally follows title, though a court can divide assets differently in a divorce.
For household planning, include the full value of all assets and debts belonging to either spouse. For an individual statement, such as one attached to a loan application, include only your legal share of each joint asset and your legal responsibility for each debt.
Do the Math
With every value and every payoff balance in front of you, the calculation is three steps:
- Add all asset values to get total assets.
- Add all liability balances to get total liabilities.
- Subtract total liabilities from total assets. That difference is your net worth.
A positive result means your assets would cover every debt if everything were liquidated today. A negative result means debts exceed assets. Negative net worth is common early in adult life, particularly when student loans or a new mortgage dominate the balance sheet, and by itself it doesn’t signal a crisis. The direction of travel over time is what tells you whether your saving, spending, and debt-repayment choices are working.
Rerun the formula quarterly or annually, using the same method and the same date logic each time so the numbers compare cleanly. More frequent updates mostly capture market noise. Over several years, a consistent series shows the pattern that a single snapshot never can.
