Your net worth is the single clearest number for measuring financial progress. It cuts through the noise of income and spending and answers one question: are you actually building wealth?
The formula is simple — assets minus liabilities — but doing it right means knowing what to count, how to value it, how to benchmark it, and how to keep the number growing. This guide walks through all of it.
What is net worth?
Net worth is everything you own (assets) minus everything you owe (liabilities).
Net Worth = Total Assets − Total Liabilities
If your assets add up to $250,000 and your debts total $90,000, your net worth is $160,000. It can be positive or negative — a new graduate with student loans and little savings may have a negative net worth, and that’s completely normal. What matters is the direction it moves over time.
Two flavors are worth knowing:
- Gross net worth — total assets minus total liabilities (the standard figure).
- Liquid net worth — only the assets you could turn into cash quickly (cash, investments), minus liabilities. This tells you what you could actually access in an emergency, since your home and car aren’t easy to spend.
Step 1: Add up your assets
Assets are anything you own that has real, sellable value. Group them so nothing slips through the cracks:
Cash and cash equivalents
- Checking and savings accounts
- Money market accounts and CDs
- Cash on hand
Investments
- Brokerage accounts (stocks, ETFs, bonds, mutual funds)
- Retirement accounts (401(k), IRA, Roth IRA, pensions)
- HSAs and 529 college savings plans
- Crypto holdings
Real estate
- Your primary home (current market value, not what you paid)
- Rental or investment properties
Personal property and other
- Vehicles (use realistic resale value, not sticker price)
- Valuable collectibles, jewelry, or equipment
- Business ownership or private equity
- Money owed to you
Add these up to get your total assets. Use current market values, and be honest — inflating your home or car value only fools you.
Step 2: Add up your liabilities
Liabilities are everything you owe. Use the current outstanding balance, not the original loan amount:
- Mortgage balance
- Auto loans
- Student loans
- Credit card balances
- Personal loans and lines of credit
- Medical or tax debt
- Any other money you owe
Add these up to get your total liabilities.
Step 3: Subtract
Subtract total liabilities from total assets. That’s your net worth.
| Amount | |
|---|---|
| Cash & savings | $18,000 |
| Investments & retirement | $142,000 |
| Home (market value) | $380,000 |
| Vehicle | $15,000 |
| Total assets | $555,000 |
| Mortgage | $295,000 |
| Auto loan | $9,000 |
| Student loans | $22,000 |
| Credit cards | $3,000 |
| Total liabilities | $329,000 |
| Net worth | $226,000 |
What to leave out
A few things commonly trip people up:
- Income and salary — net worth is a snapshot of what you have, not what you earn. High earners can have low net worth.
- Monthly expenses — these affect net worth over time but aren’t part of the calculation itself.
- Depreciating stuff at retail price — furniture, electronics, and clothing rarely have meaningful resale value. Skip them or use conservative numbers.
- Term life insurance — it has no cash value (whole-life policies do).
Common mistakes to avoid
- Overvaluing your home and car. Use current market value, and remember you’d pay fees to actually sell.
- Forgetting old retirement accounts. A 401(k) from a job you left three years ago still counts.
- Ignoring debt behind “good” assets. A $400,000 house with a $380,000 mortgage adds only $20,000 to your net worth.
- Counting investment gains as your own contributions. When you review how your portfolio is doing, separate the money you added from the money the market earned. Mixing them makes a good month look better than it was — and a bad one worse. (More on this below.)
How do you compare? Net worth benchmarks
It’s natural to want a benchmark. Just remember that averages are skewed upward by the ultra-wealthy — the median (the middle household) is a far more realistic yardstick than the average, and both vary widely by age, region, and cost of living.
Rather than chase someone else’s number, use a personal benchmark. One popular rule of thumb from The Millionaire Next Door is:
Expected net worth = (Age × Annual pre-tax income) ÷ 10
So a 40-year-old earning $80,000 would have an expected net worth around $320,000. Hit that and you’re a solid accumulator of wealth; double it and you’re doing exceptionally well. It’s a rough guide, not gospel — but it beats comparing yourself to a headline average.
The most useful benchmark of all is your own net worth last year. Beating your past self, consistently, is the entire game.
How to grow your net worth
There are only two levers, and both matter:
- Grow assets. Save and invest consistently. Automate contributions to retirement and brokerage accounts so growth happens without willpower. Time in the market and compounding do the heavy lifting.
- Shrink liabilities. Pay down high-interest debt aggressively — credit card balances especially, where the interest often outruns any investment return. Every dollar of debt eliminated raises net worth just as surely as a dollar saved.
A few habits that compound over the years:
- Increase your savings rate, not just your income. Raises quietly disappear if spending rises to match them.
- Keep housing and vehicle costs in check — the two biggest budget lines for most households.
- Invest for the long term and avoid reacting to short-term market swings.
- Track your investment returns honestly so you know what’s actually working.
That last point is where most people — and most apps — get tripped up. If you add $10,000 to your brokerage account and it grows to $60,000 from $48,000, it looks like a $12,000 gain. But $10,000 of that was your own deposit; the market only earned you $2,000. Confusing the two makes it impossible to tell whether your investing is any good. The fix is a flow-adjusted return (also called a money-weighted return), which strips out your deposits and withdrawals to show true performance.
How often should you calculate it?
Once a month is the sweet spot. Frequent enough to catch trends, infrequent enough that daily market swings don’t rattle you. Pick a consistent day — the first of the month works well — and log the number each time.
The magic isn’t in any single calculation. It’s in the trend line. Watched over years, a net worth that climbs up and to the right is the clearest proof you’re on the right track.
Do it the easy way: track it automatically
Calculating net worth by hand once is a great exercise. Doing it every month, across a dozen accounts, gets tedious fast — and manual spreadsheets go stale the moment a balance changes.
That’s what a net worth tracker is for. NetTrack connects your bank, brokerage, and retirement accounts, rolls everything into one net worth figure, and updates it automatically. It also computes the flow-adjusted return described above, so the deposits and withdrawals you make don’t get mistaken for market gains — you see how your portfolio actually performed.
Frequently asked questions
What should my net worth be at my age?
There’s no universal target. As a rough guide, The Millionaire Next Door suggests (age × annual income) ÷ 10. More important than any benchmark is that your net worth is trending upward year over year.
Is my house part of my net worth?
Yes — count your home’s current market value as an asset and your remaining mortgage as a liability. The difference (your equity) is what actually adds to net worth. If you want to know what you could access quickly, look at liquid net worth, which excludes your home.
Does my 401(k) count toward net worth?
Absolutely. Retirement accounts — 401(k)s, IRAs, pensions, HSAs — are assets and often make up the largest share of a household’s net worth. Include old accounts from past employers, too.
What’s a good net worth?
A “good” net worth is one that’s positive, growing, and on track for your goals. Comparing to national averages is misleading because they’re skewed by the ultra-wealthy — benchmark against your own past instead.
How is net worth different from income?
Income is what you earn; net worth is what you keep. It’s entirely possible to earn a high salary and have a low (or negative) net worth if spending and debt keep pace. Net worth is the truer measure of financial health.
The bottom line
Net worth is assets minus liabilities — simple to calculate, powerful to track. Add up what you own, subtract what you owe, and check the number monthly. Grow it by saving consistently, paying down debt, and measuring your investment returns honestly. Whether you’re climbing out of debt or building toward financial independence, that single figure, watched over time, tells you the truth about your progress.
