How to Calculate Your Net Worth in 15 Minutes
Most people can tell you roughly what they earn. Far fewer can tell you what they are actually worth. That gap matters, because income describes a flow while net worth describes a position — where you stand once everything you own is set beside everything you owe.
You don't need a spreadsheet with forty tabs or an advisor on retainer. With your account logins, a rough sense of your loan balances, and fifteen uninterrupted minutes, you can produce a number that's accurate enough to be genuinely useful. Here is the whole process.
Start With What You Own
An asset is anything you own that holds cash or resale value. Not what you paid for it, not what it would cost to replace — what it would realistically turn into if you sold it or cashed it out.
Walk through this list and write down a number for every item that applies to you:
- Checking and savings balances
- Money market accounts and certificates of deposit
- Brokerage and retirement accounts — 401(k), 403(b), IRA, Roth IRA
- Health savings account balances
- Pension values, if your plan provides a statement figure
- Your home, at a market value you could defend
- Cars, motorcycles, boats and other titled property at private-sale value
- An ownership stake in a business you can reasonably value
- Cash value inside a permanent life insurance policy, if it has any
Then leave out the tempting stuff: your salary (that is income, not an asset), an expected inheritance, furniture priced at retail, and collections you would never actually sell. If you want household goods counted, use a garage-sale figure and accept that it's a rounding error.
Then Add Up What You Owe
A liability is any debt you owe, measured at its current payoff balance. The original loan amount is history; what remains is your liability.
- Credit card balances — use the full statement balance, not the minimum payment
- Mortgage and home equity loans or lines of credit
- Auto loans
- Student loans
- Personal loans, including money borrowed from family that you intend to repay
- Medical bills you are still paying down
- Buy-now-pay-later balances
- Taxes you owe but haven't paid yet
Be honest here. A debt you've stopped looking at is still subtracting from your total, and hiding it only shrinks the usefulness of the exercise.
The Formula Is One Subtraction
Net worth = total assets − total liabilities.
Here's a worked example. Say your assets are a checking account at $3,200, savings at $11,500, a 401(k) at $68,000, a Roth IRA at $14,000, a car worth $9,000, and a condo valued at $285,000. That totals $390,700. Your liabilities are a $212,000 mortgage, a $6,400 auto loan, $1,850 in credit card balances, and $9,300 in student loans, totaling $229,550. Subtract, and your net worth is $161,150.
A negative result is common and not a verdict on your character. A new mortgage or a stack of student loans will do it. What matters is the direction the number moves over the next few years.
Your 15-Minute Worksheet
- Set a timer for fifteen minutes and open your accounts in one browser window. Don't reorganize anything — you are only reading balances.
- List your assets in a left column with a dollar figure beside each one.
- List your liabilities in a right column the same way.
- Total each column and subtract the right from the left.
- Write today's date at the top. A number without a date is trivia; a number with a date is a data point.
- Save it somewhere you'll find again — a note on your phone, a single spreadsheet tab, a page in a notebook.
- Resist fixing anything today. Recording comes first; adjusting comes later.
If you run out of time, estimate your home value from a recent nearby sale and move on. A finished estimate beats a precise figure you never complete.
Three Judgment Calls That Trip People Up
Your home
Some people count the house and the mortgage together; others leave both out and track only liquid wealth. Both approaches are fine as long as you pick one and stick with it. What you shouldn't do is count the house and forget the mortgage.
Your car and its loan
Use private-party value rather than dealer retail, and include the loan alongside it. The two will roughly cancel out, which is the honest picture — a car is rarely a store of wealth.
Retirement accounts
Use the balance printed on your statement. Yes, you'll owe income tax when you withdraw from a pre-tax account, and no, you don't need to model that today. Consistency matters more than precision. The same accounts should get the same treatment every time you run the numbers. Also watch for double counting: money you've set aside in savings for a tax bill is still one asset, not two.
Track the Trend, Not the Verdict
A single net worth figure tells you where you started. Three or four tell you something far more useful about your habits. Run the worksheet on the same day each quarter — the first weekend of January, April, July, and October works well — and keep every version in one place so you can read the pattern.
If the number drops, look at which column moved. Falling assets and rising debt call for different responses.
Look at what changed between entries. Did the savings balance climb while the credit card balance fell? That's progress, even if the total barely budged because the market dipped. Did the debt column grow while the asset column stayed flat? That's a signal worth acting on, and it's much easier to spot in a row of dated snapshots than in a vague feeling that money has been tight.
One last note: this worksheet is a personal tracking tool, not tax or investment advice. If your situation includes a business, a trust, or complicated tax positions, a fee-only financial planner or a CPA can help you value things properly.
