How to Calculate Net Worth: A 4-Step Formula That Works
Net worth is what you own minus what you owe. Follow 4 steps with a worked example to list assets, subtract debts, and track progress each year.

To calculate net worth, add up everything you own, subtract everything you owe, and write down the result. The Financial Industry Regulatory Authority (FINRA) describes it the same way: add up what you own (assets) and subtract what you owe (liabilities).
Income tells you what flows in each month, but it does not show the full picture. A high earner can carry heavy debt and own very little, while a modest earner can hold savings and growing investments. This guide walks through the calculation in four steps, with a worked example you can reproduce.
Step 1: List everything you own
Start with your assets. FINRA's examples include investments, savings, personal property, and your home or other real estate.
Be thorough but realistic. Include checking and savings accounts, retirement and investment accounts, the market value of your home and vehicles, and valuable personal property. Colorado State University Extension advises using current market value, which it describes as the amount you could sell the asset for today, not what it cost when it was new. A car bought for $25,000 that is now worth $14,000 counts as $14,000.
Step 2: List everything you owe
Now list your liabilities. FINRA's examples include mortgages, credit card balances, and personal or auto loans.
Add any other debts that apply to you, such as student loans, home equity loans, medical bills, or unpaid taxes. Colorado State Extension recommends documenting all debts using the most current balances from your creditors or statements. Small balances count too, because every dollar owed offsets a dollar owned.
Step 3: Subtract liabilities from assets
The formula is one line: net worth equals total assets minus total liabilities. If your assets are larger, you have positive net worth. If your debts are larger, you have negative net worth.
A negative number is a starting point, not a verdict. It simply says that paying down debt will move the number more than saving will, for now.
Step 4: Repeat the math every year
One calculation is a snapshot, and snapshots become useful when they turn into a series. FINRA says that regular net worth assessments, say annually, provide a measurable way to track your financial progress over time.
Colorado State Extension suggests preparing an updated statement at about the same time each year. Reuse the same categories so the numbers stay comparable. When the number rises, note what drove it: higher savings, lower debt, or market gains.
Judgment calls that come up often
Two choices trip people up. First, value assets at what you could sell them for today. For a home, you might use a recent appraisal, a tax assessment, or comparable sales in your area, and then subtract the full remaining mortgage balance, not just the principal you have paid so far.
Second, include the full current balance of each debt. Leaving out a small medical bill or an old store card does not make the number more useful. The point of the exercise is completeness, because the result only helps if it reflects reality.
Common mistakes that skew the number
The most common error is counting a home's market value while forgetting the mortgage balance. Both belong on the sheet, on opposite sides. Another is listing a car's purchase price instead of its current value.
A third mistake is mixing dates, such as assets valued today alongside a debt balance from three months ago. Pick one date, gather current numbers for everything, and do the math once.
Three ways the number can change
Net worth moves for only a few reasons, and naming them helps you read your own result. Assets can grow because you saved or invested more. Liabilities can shrink because you paid down balances. Values can also shift on their own, such as when the market value of a car falls or an investment account rises or drops.
Keep a short note next to each year's result that says which of these happened. Over time, the notes show which habit moved the number most. Some people also record retirement accounts separately, because withdrawals from them may be taxed, and note that choice on the sheet so each year stays comparable.
Worked example with stated assumptions
The numbers below are hypothetical and use these stated assumptions: savings $6,000, investments $12,000, car valued at $14,000, other property $2,000, credit card balance $5,000, car loan $9,000, and student loan $8,000. Every figure is an assumption, and the arithmetic is reproducible by addition and subtraction.
| Category | Item | Value |
|---|---|---|
| Assets | Savings | $6,000 |
| Assets | Investments | $12,000 |
| Assets | Car | $14,000 |
| Assets | Other property | $2,000 |
| Assets | Total | $34,000 |
| Liabilities | Credit card | $5,000 |
| Liabilities | Car loan | $9,000 |
| Liabilities | Student loan | $8,000 |
| Liabilities | Total | $22,000 |
| Result | Net worth | $12,000 |
Total assets of $34,000 minus total liabilities of $22,000 gives a net worth of $12,000. Now run the same sheet with your own numbers. List each asset at its current value, each liability at its current balance, subtract, and write down the date.
Next year, do it again and compare. The change between the two results is the clearest sign of whether your plan is working.
