How to Calculate Your Net Worth: A Simple Step-by-Step Guide
Your net worth is the single most important number in your financial life. It tells you exactly where you stand financially " — whether you're building wealth or falling behind. Calculating it takes 30 minutes and should be updated quarterly. Here's exactly how to do it.
The Formula: Assets Minus Liabilities
Your net worth is calculated with one simple formula:
Assets are everything you own that has monetary value. Liabilities are everything you owe. The difference is your net worth. If your assets exceed your liabilities, you have a positive net worth. If your liabilities exceed your assets, you have a negative net worth " — meaning you owe more than you own.
Step 1: List All Your Assets
Go through each category and enter the current market value (not what you paid for it):
| Asset Category | Examples | Where to Find Value |
|---|---|---|
| Cash & Savings | Checking, savings, emergency fund | Bank statements |
| Investments | 401(k), IRA, brokerage, stocks, bonds | Account statements |
| Real Estate | Primary home, rental property, land | Zillow estimate or appraisal |
| Vehicles | Cars, trucks, motorcycles, RVs | Kelley Blue Book value |
| Personal Property | Jewelry, art, collectibles, furniture | Estimated resale value |
| Business Interests | Ownership in businesses | Current market value or book value |
| Other Assets | Pension value, life insurance cash value | Provider statements |
Step 2: List All Your Liabilities
Enter the current balance owed on each debt:
| Liability Category | Examples | Where to Find Balance |
|---|---|---|
| Mortgage | Primary home, rental property loans | Monthly statement or lender website |
| Auto Loans | Car, truck, RV loans | Lender statement |
| Student Loans | Federal and private loans | Servicer website (StudentAid.gov) |
| Credit Cards | All cards with balances | Current statement balance |
| Personal Loans | Bank loans, family loans | Lender statement |
| Medical Debt | Unpaid medical bills | Provider statement |
| Tax Debt | IRS or state tax obligations | Notice from taxing authority |
| Other Debt | Payday loans, store credit | Creditor statement |
Step 3: Calculate Your Net Worth
Subtract total liabilities from total assets. That's your net worth.
Example Calculation
| Assets | Value |
|---|---|
| Checking & Savings | $12,000 |
| 401(k) | $45,000 |
| Primary Home | $350,000 |
| Car | $18,000 |
| Total Assets | $425,000 |
| Liabilities | Balance |
|---|---|
| Mortgage | $280,000 |
| Auto Loan | $12,000 |
| Student Loans | $28,000 |
| Credit Cards | $4,500 |
| Total Liabilities | $324,500 |
Net Worth = $425,000 - $324,500 = $100,500
Average Net Worth by Age
| Age Group | Median Net Worth | Mean Net Worth |
|---|---|---|
| Under 35 | $39,000 | $118,100 |
| 35-44 | $135,300 | $364,200 |
| 45-54 | $247,200 | $822,900 |
| 55-64 | $364,500 | $1,175,900 |
