Free Net Worth Calculator — Assets Minus Liabilities
November 3, 2026 · 3 min read · By the DollarWise team
How it works
List everything you own (cash, investments, home, car and other assets) and everything you owe (mortgage, loans, credit cards and other debts). This calculator totals each side and subtracts liabilities from assets to give you your net worth — and, if you share your age and income, compares it with a common age-based benchmark.
## How the math works
Net worth is simply everything you own minus everything you owe:
**Net worth = (cash + investments + home + other assets) − (mortgage + loans + credit cards + other liabilities)**
Each item is entered at its current value — use today's market price for investments and a realistic resale estimate for a home or car, not what you paid. The optional benchmark uses the widely cited "expected net worth" formula from *The Millionaire Next Door*: **age × annual pre-tax income ÷ 10**. It is a rough rule of thumb, not a personalized target.
## Everyday uses
- **Annual check-up:** recompute once a year to see whether your net worth is actually growing, not just your income.
- **Debt-payoff motivation:** watch how paying off a high-interest credit card lifts your net worth dollar for dollar.
- **Big-decision filter:** before a major purchase, estimate how it moves both sides of the ledger and what it does to your net worth.
## Frequently asked questions
### Should I include my car and home at purchase price or current value?
Current value. Net worth is a snapshot of today, so use a realistic resale estimate (e.g. recent comparable sales for a home, Kelley Blue Book for a car). Overstating assets gives you a falsely comforting number.
### Is a negative net worth bad?
It is common early in life (e.g. right after college with student loans) and not permanent. The key is the trend: if your net worth is rising year over year, you are on the right path. Focus first on high-interest debt.
### Why does the benchmark use income instead of expenses?
The "age × income ÷ 10" rule is a quick relative benchmark, not a goal. Someone with a high income but low savings rate can fall below it, and a disciplined saver can exceed it. Use it as motivation, not as a diagnosis.
