How the net worth calculator works
Net worth is a single snapshot of your financial position: everything you own minus everything you owe. The calculator adds up your assets (cash, investments, property, vehicles, retirement accounts) and your liabilities (mortgages, loans, credit card balances), then subtracts one total from the other.
The formula is simply netWorth = sum(assets) - sum(liabilities). Each asset and each liability is entered as a positive amount, since they are magnitudes of value. The calculator sums each list, rounds each total to the nearest cent, and subtracts liabilities from assets. The final figure is also rounded to cents. A negative result is valid and returned unchanged, which happens whenever you owe more than you own.
All arithmetic runs on whole cents and rounds half away from zero, so the totals match what you would get on paper rather than drifting through floating-point noise. Negative entries are rejected: a debt belongs in the liabilities list as a positive balance, never as a negative asset. Because the math is currency-agnostic, the result reads in whatever currency you used for your inputs, as long as every figure shares that one currency.
Worked example
Suppose you list the following in one currency.
Assets
- Checking and savings: 18,000
- Investment account: 42,500
- Retirement account: 95,000
- Home market value: 320,000
- Car: 14,000
Liabilities
- Mortgage balance: 248,000
- Car loan: 9,500
- Credit card balance: 3,200
- Student loan: 21,000
The calculator works through it like this:
| Step | Value |
|---|---|
| Total assets | 489,500.00 |
| Total liabilities | 281,700.00 |
| Net worth | 207,800.00 |
Total assets are 18,000 + 42,500 + 95,000 + 320,000 + 14,000 = 489,500. Total liabilities are 248,000 + 9,500 + 3,200 + 21,000 = 281,700. Net worth is 489,500 - 281,700 = 207,800.
How to use it
- Enter the current value of each asset, not its original purchase price.
- List every liability as the outstanding balance you owe today, not the original loan amount.
- Keep everything in one currency. Convert foreign holdings before entering them.
- Enter each amount as a positive number. The calculator treats them as magnitudes and handles the subtraction for you.
- Leave a row blank or at zero if it does not apply; an empty list sums to zero and will not break the result.
- Re-run it every few months and record the figure. The trend over time tells you more than any single snapshot.
Limitations
This is an estimate, not financial advice. It is only as accurate as the values you enter, and it captures a single moment rather than your income, spending, or future earning potential. It does not adjust for taxes owed on selling an asset, transaction costs, inflation, or the liquidity of each holding (a house cannot be spent as easily as cash). Use it to track direction over time and to compare scenarios, and consult a qualified financial professional for decisions that carry real consequences.
Frequently asked questions
Should I enter my mortgage balance as an asset or a liability?
The remaining mortgage balance is a liability, since it is money you owe. The home's current market value is the asset. Listing both separately lets the calculator show your true equity, because the net result already subtracts what you still owe from what the property is worth.
Can my net worth be negative?
Yes. When your total liabilities are larger than your total assets, the result is a negative number, and the calculator returns it as-is. This is common early in life when student loans or a new mortgage outweigh savings, and it usually improves as balances are paid down and assets grow.
Should I use the purchase price or the current value of my assets?
Always use current market value, not what you paid. A car, a home, and a stock portfolio are each worth what they would sell for today, which can be higher or lower than the purchase price. Using current values keeps the snapshot honest.
Do I include my retirement accounts?
Yes. Balances in retirement accounts such as a 401(k), IRA, or pension fund are assets and belong in the total. If you want a picture of money you could access immediately, you can run the calculator a second time without them to compare.
Is my data sent anywhere when I use this?
No. Every figure you type is processed in your browser and is never transmitted, logged, or stored on a server. You can close the tab and nothing about your finances leaves your device.
