What is a net worth calculator?
A net worth calculator estimates a personal balance by adding assets and subtracting liabilities. This NumberMotive version also shows the asset subtotal, the liability subtotal and, when there is debt, an assets-to-liabilities ratio.
The result is an educational estimate from the numbers you type. It is not financial advice, an official asset valuation, a tax return, professional valuation or an official financial statement.
How net worth is modeled here
The model is a simple balance sheet. Every asset field is added. Every liability field is added. Net worth is assets minus liabilities. Home equity is not a separate line. If you enter a real-estate value and a mortgage balance, the difference is already inside the net-worth result.
Market prices, appraisals, tax basis, liquidity and credit reports are outside this worksheet. The amounts are whatever you type.
The formulas this calculator uses
Total assets = cash and savings + investments + retirement accounts + real estate + vehicles + other assets
Total liabilities = mortgage balance + student loans + credit cards + auto loans + other debt
Net worth = total assets − total liabilities
Assets-to-liabilities ratio = total assets ÷ total liabilities, only when liabilities are greater than $0.00. When liabilities are $0.00, the ratio is not estimated. The calculator does not return NaN or Infinity.
Worked example
With $10,000.00 cash, $40,000.00 investments, $80,000.00 retirement accounts, $350,000.00 real estate, $15,000.00 vehicles and $5,000.00 other assets, total assets are $500,000.00.
With a $200,000.00 mortgage, $25,000.00 student loans, $5,000.00 credit cards, $15,000.00 auto loans and $5,000.00 other debt, total liabilities are $250,000.00. Net worth is $250,000.00. The assets-to-liabilities ratio is 2.00.
Raising the mortgage to $600,000.00 makes liabilities $650,000.00 and net worth −$150,000.00. None of those inputs is a recommended portfolio, debt plan or wealth target.

Frequently asked questions
What is a net worth calculator?
It estimates a personal balance by adding assets and subtracting liabilities. This NumberMotive version also shows the asset subtotal, the liability subtotal and, when there is debt, an assets-to-liabilities ratio. It is an educational worksheet, not an official statement.
How is net worth calculated?
Net worth = total assets − total liabilities. With the $500,000.00 / $250,000.00 example, net worth is $250,000.00. A larger liability total can make the result negative.
What counts as an asset in this calculator?
Assets are the six amounts you type: cash and savings, investments, retirement accounts, real estate, vehicles and other assets. The calculator does not look up accounts or assign market values.
What counts as a liability in this calculator?
Liabilities are the five amounts you type: mortgage balance, student loans, credit cards, auto loans and other debt. The calculator does not pull a credit report or a lender statement.
How is the assets-to-liabilities ratio calculated?
When liabilities are greater than $0.00, the ratio is total assets divided by total liabilities. On $500,000.00 of assets and $250,000.00 of liabilities, the ratio is 2.00. It is a worksheet figure, not a credit score.
What if total liabilities are $0?
A $0.00 liability total is valid. Net worth equals total assets. The ratio is not estimated. The calculator does not divide by zero or return Infinity.
What if total assets are $0?
A $0.00 asset total is valid. If liabilities remain, net worth is negative. If both sides are $0.00, net worth is $0.00 and the ratio is not estimated.
Can net worth be negative?
Yes. If liabilities are larger than assets, the result is a negative dollar amount. Raising the mortgage in the worked example to $600,000.00 produces −$150,000.00. That is a worksheet result, not a credit decision.
How should I enter investments?
Enter a current amount you want to treat as investments. The field does not look up tickers, recommend a portfolio or convert a brokerage statement.
How should I enter retirement accounts?
Enter a current balance you want to include. The field is not an official 401(k), IRA or plan-provider statement and does not apply tax or withdrawal rules.
How should I enter real estate?
Enter a current value you assign. The field is not an appraisal, tax assessment or sale price. The mortgage is entered separately as a liability.
Does this include home equity as a separate line?
No. Equity is not a separate field. If you enter a real-estate value and a mortgage balance, the difference is already inside net worth.
How should I enter credit cards and other debt?
Enter the balances you want to treat as liabilities. The calculator does not look up minimum payments, interest rates or a recommended payoff order.
Is this an official net worth statement or tax form?
No. It is an educational estimate from numbers you typed. It is not a tax return, estate inventory, loan application exhibit or official financial statement.
Does this track wealth over time?
No. Inputs stay in the current page view. Scenarios are not saved, emailed or sent to analytics, so the page does not keep a wealth history.
Is this result financial advice or a professional valuation?
No. It is an educational estimate from assets and liabilities you chose. It is not financial advice, an official asset valuation, a tax return or professional valuation.
