Net worth is the single most complete snapshot of your financial health. Unlike income (which measures cash flow) or savings balance (which ignores debt), net worth captures everything — what you own minus what you owe — in one number. It's the benchmark used by financial planners, retirement calculators, and wealth managers to measure real financial progress.
Calculating it takes less than 30 minutes. Understanding what it means and how to grow it takes a bit more, but this guide covers both.
Net Worth = Total Assets − Total Liabilities
If your assets total $380,000 and your liabilities total $210,000, your net worth is $170,000. If you're just starting out and owe more than you own, a negative net worth is common and not a crisis — it's a starting point.
Assets are anything you own that has monetary value. Be honest but realistic — include only things you could actually convert to cash:
Don't include personal property like clothing, furniture, or most electronics — they depreciate too quickly and aren't meaningfully liquid.
The Federal Reserve's Survey of Consumer Finances provides the most authoritative data on American household wealth. These figures are for households, not individuals:
| Age Group | Median Net Worth | Mean Net Worth |
|---|---|---|
| Under 35 | $39,000 | $183,000 |
| 35–44 | $135,000 | $549,000 |
| 45–54 | $247,000 | $975,000 |
| 55–64 | $364,000 | $1,566,000 |
| 65–74 | $409,000 | $1,794,000 |
| 75+ | $335,000 | $1,624,000 |
Notice the enormous gap between median and mean. A handful of ultra-wealthy households pull the mean far above what a typical family holds. The median is the better benchmark for most people. The median for under-35 households is $39,000 — but negative net worth is common at this age and not unusual at all.
Financial planner Thomas Stanley's rule of thumb from The Millionaire Next Door suggests that your target net worth should be: Age × Gross Annual Income ÷ 10. So a 40-year-old earning $80,000 should target $320,000 in net worth to stay on track for financial independence.
Another common benchmark: by age 30, aim for net worth equal to your annual salary. By 40, three times your salary. By 50, six times. By 60, eight times. These are rough guidelines, not rigid rules — they assume you want to retire around 65 at roughly your current income level.
Income is a flow; net worth is a stock. You can earn a high income and still have low or negative net worth if you spend everything you make. Conversely, you can build substantial net worth on a modest income through consistent saving and compound growth over decades.
The most powerful insight from tracking net worth is that it makes the invisible visible. When you see your retirement account growing, your mortgage balance shrinking, and your net worth increasing year over year, financial decisions feel less abstract. You're not just "saving money" — you're watching real wealth accumulate.

Mortgage Calculator →Yes. Even though you can't access it without penalty before 59½, your retirement account balance is real wealth that belongs to you. It should absolutely be included in your net worth calculation. Most financial planners include it at full value, though some conservative analysts reduce it by an estimated future tax liability.
Not necessarily, especially when young. A 25-year-old with $40,000 in student loans but a college degree and promising career often has very high future earning potential — their human capital far exceeds their negative financial net worth. What matters most is the trajectory: is it improving each year?
Once or twice a year is sufficient for most people. Calculating it monthly can create unnecessary anxiety from market fluctuations. Annually gives you a clear year-over-year comparison without the noise. Many people calculate it on January 1st each year as a financial health check-in.
Yes, but realistically. Use your home's current estimated market value (Zillow or a recent comparable sale) minus your current mortgage payoff amount. This is your home equity and it's a genuine asset. However, because a home is illiquid and expensive to sell, some planners recommend tracking net worth both with and without home equity to understand your liquid vs. total wealth.
