How do you calculate your networth? You add up everything you own, subtract everything you owe, and the result is your net worth. It takes about half an hour the first time, and it is one of the most useful numbers in personal finance because it shows where you stand, whatever your income looks like.
Step 1: List what you own
Open a spreadsheet or grab a notebook and write down your assets. Use realistic current values, not what you hope they are worth.
- Cash: checking, savings and any money you hold at home.
- Investments: brokerage accounts, funds and shares.
- Retirement accounts: pensions, 401(k)s, IRAs and similar.
- Property: your home, land or other real estate at a fair market value.
- Vehicles: use what a buyer would pay, not what you paid.
- Business interests: your share, valued cautiously.
- Valuables: jewellery, art and collectibles, only if you could sell them.
Step 2: List what you owe
Next come liabilities. People skip this step and end up flattering themselves.
- Mortgage balance and home equity loans
- Car loans
- Student loans
- Credit card balances
- Personal loans and money owed to family
- Unpaid taxes or bills
Step 3: Subtract
The formula is simple: total assets minus total liabilities equals net worth. A positive number means you own more than you owe. A negative one is common for younger people with student debt, and it is not a failure, just a starting line.
A worked example
Say Sam has $12,000 in savings, $30,000 in a retirement account, a car worth $8,000 and a home worth $250,000. That is $300,000 in assets. Sam owes $180,000 on the mortgage, $9,000 on the car loan and $3,000 on credit cards, which is $192,000. The net worth is $300,000 minus $192,000, or $108,000. Nothing fancy, but now Sam has a baseline.
Step 4: Decide how to treat awkward items
Your home
Include it, but know that you cannot spend it without selling or borrowing against it. Some people also calculate a second figure without the home, which shows what is actually investable.
Retirement accounts
Count the balance, though remember that withdrawals may be taxed. Some people reduce the value slightly to be conservative.
Things with sentimental value
If you would never sell it, leave it out. A figure you cannot realise is not helping your plan.
Step 5: Track it on a schedule
One calculation is a snapshot. The value comes from repeating it, once or twice a year, on a regular date. Put the numbers in a simple table and watch the trend. Markets and house prices will move it up and down, so focus on the direction over several years rather than each month.
How do you calculate your networth if you have a business?
Value your share cautiously. Use what the business could realistically sell for, or a conservative multiple of profit, and subtract any personal guarantees on its debts. If you are unsure, get an accountant to help, because private business values are notoriously hard to pin down.
Common mistakes
- Using purchase price instead of current value for cars and gadgets.
- Forgetting small debts, such as buy-now-pay-later balances.
- Counting expected inheritances or bonuses that you do not have yet.
- Mixing joint and personal figures in a household.
- Letting a high income distract from the actual balance sheet.
Using the number
Once you have it, compare it with your own earlier figures rather than with other people. If you want a broad idea of how households fare, the Federal Reserve publishes the Survey of Consumer Finances with medians by age and other groups. Use it as context, not a scorecard.
The aim is progress. If the number grows through saving, paying down debt and steady investing, you are doing the right things, whatever the headline total says today.

Quick habits that make it easier
- Pick one date each year, such as your birthday or New Year, and always calculate then.
- Keep a running list of account logins and balances in a secure place.
- Use rounded numbers. Precision to the dollar is not needed.
- Record your home value using recent local sale prices, not a hopeful guess.
- Save last year’s sheet so you can see the change.
What to do if your number is negative
Do not panic. A negative figure is very common in your twenties and early thirties, especially with student loans or a new mortgage on a small deposit. Focus on the trend. Pay down the expensive debt first, keep a small emergency fund so you do not borrow for surprises, and start investing steadily when you can. Within a few years most people see the line cross zero.
Many free apps connect to your accounts and calculate this automatically. They are convenient, but check that they pick up everything, including accounts they cannot connect to, and be careful about which services you give your login details to.
