Net worth is the single most important number in personal finance. It tells you exactly where you stand financially at any point in time — and tracking it over the years is the most reliable way to measure whether you are making real progress toward financial independence. Here is how to calculate it and what to do with the number.
The Net Worth Formula
Net Worth = Total Assets − Total Liabilities
That is it. Add up everything you own, subtract everything you owe, and the result is your net worth. It can be positive or negative — and both are useful data points.
What Counts as an Asset?
Assets are things you own that have financial value:
- Cash and bank accounts: Checking, savings, money market accounts
- Investment accounts: Brokerage, 401(k), IRA, HSA balances
- Real estate: Current market value of your home or investment properties
- Vehicles: Current market value (use Kelley Blue Book)
- Business equity: Your ownership stake if you own a business
- Other valuable assets: Valuable jewelry, collectibles, equipment
What Counts as a Liability?
Liabilities are debts and obligations you owe:
- Mortgage balance(s)
- Car loan balances
- Student loan balances
- Credit card balances
- Personal loan balances
- Medical debt
- Any other money you owe
A Simple Example
Suppose you have:
- $15,000 in checking and savings
- $45,000 in your 401(k)
- $220,000 home value with a $170,000 mortgage remaining
- $12,000 car with an $8,000 loan
- $5,000 in credit card debt
Assets: $15,000 + $45,000 + $220,000 + $12,000 = $292,000
Liabilities: $170,000 + $8,000 + $5,000 = $183,000
Net Worth: $292,000 − $183,000 = $109,000
What Is a Good Net Worth?
Net worth benchmarks by age are rough guidelines — not targets that define your success. That said, a commonly cited rule of thumb from financial planners is:
- By 30: 1x your annual salary
- By 40: 3x your annual salary
- By 50: 6x your annual salary
- By 60: 8x your annual salary
If you are behind these benchmarks, do not panic — they assume starting to save in your 20s. What matters most is your trajectory, not your current number.
How to Build Net Worth Over Time
Net worth grows in two ways: by accumulating more assets or by reducing liabilities. The most effective levers are:
- Increasing income and saving a meaningful percentage
- Investing savings in diversified, low-cost index funds
- Paying down high-interest debt aggressively
- Avoiding lifestyle inflation as your income grows
Track It Every Month or Quarter
Tracking your net worth regularly — even on a simple spreadsheet — is one of the most motivating habits in personal finance. Seeing the number grow steadily reinforces good behaviors and makes abstract financial goals feel tangible. Apps like Personal Capital, Copilot, and Monarch Money automate this process.
Bottom Line
Net worth is your financial scoreboard. Calculate it today, track it over time, and use it to make better decisions about spending, saving, and investing. The direction of the trend matters more than where you start.
