How to Calculate Your Net Worth (Worksheet + Free Tool)
Net worth is the single number that summarizes your financial life better than any other. It tells you, in one figure, what your overall financial position is independent of how much you earn, how flashy your spending looks, or what your credit score says. People with high incomes and zero net worth are surprisingly common. So are people with modest incomes and surprisingly large net worths. Calculating yours takes about thirty minutes the first time and ten minutes every time after that. This guide walks through the formula, what to include on each side of the ledger, why net worth is a more honest measure than income, and how to track yours over time without it becoming a chore.
The Formula
The formula is genuinely just one line:
Net Worth = Total Assets − Total Liabilities
Assets are things you own that have monetary value. Liabilities are things you owe. Subtract one from the other and you get your net worth. The number can be negative, especially in your 20s when student loans dominate, and that's fine — what matters is the trajectory over time, not the snapshot.
The hard part isn't the math. It's deciding what counts. Some things are obvious (cash in a checking account is an asset; a credit card balance is a liability). Others are debatable (do you count your car? at what value? what about the engagement ring?). The conventions below are what most financial planners use and what makes net worth comparable across years and across people.
One philosophical point: net worth is a snapshot, like stepping on a scale. Tracked once, it's a vanity number. Tracked quarterly over a decade, it becomes one of the most powerful behavioral tools in personal finance because it makes invisible things visible. The number doesn't lie.
What Counts as an Asset
Use current market value, not what you paid. If you bought a couch for $1,500 four years ago, its current market value is closer to $200. Use $200 (or $0 — most people don't bother to count furniture at all).
Cash and cash equivalents. Checking accounts, savings accounts, money market funds, certificates of deposit, physical cash. If it's denominated in dollars and accessible within a few days, it counts here.
Retirement accounts. Use the current balance shown by your provider. 401(k), 403(b), Traditional IRA, Roth IRA, SEP-IRA, Solo 401(k), pension lump-sum value if applicable. Don't try to discount for future taxes; the convention is to use the gross balance.
Brokerage accounts. Taxable investment accounts (Vanguard, Fidelity, Schwab, Robinhood, etc.). Use today's balance, not what you contributed.
Real estate. For your primary home, use the current market value (Zillow estimate is fine for personal tracking; professional appraisal isn't required). For investment properties, same approach. Don't list the purchase price unless you bought yesterday.
Vehicles. Use the current trade-in value, which you can look up on Kelley Blue Book or Edmunds. The "what I paid" number is meaningless because cars depreciate sharply. A car bought for $35,000 four years ago is probably worth $18,000-$22,000 in trade-in now. List that, not the $35,000.
Business equity. If you own a business, use a conservative valuation. For a small service business, this might be 1-2x annual profit. For an established business with audited financials, use the most recent valuation.
HSA balance. Yes, count it as an asset. Even though it's earmarked for medical expenses, after age 65 it functions like a Traditional IRA.
Other. Cryptocurrency at current market value, valuable jewelry (use insurance appraisal, not retail), collectibles only if there's an active resale market for them. Don't count: items that won't realistically sell, expected inheritance, future stock options that haven't vested.
A useful sanity check before you commit to your asset list: a net worth calculator will let you plug in each category and shows the running total without spreadsheet work.
What Counts as a Liability
This side is shorter and easier. List the current balance you owe, not the original loan amount and not the future total with interest.
Mortgage. The current principal balance on your primary home and any investment properties. If you're 8 years into a 30-year mortgage on a $300K loan, your current balance is probably around $250K. Use that.
Auto loans. Current payoff balance on each car loan.
Student loans. Current total across federal and private. If you have multiple loans, you can list the total or break them out; either is fine as long as you're consistent.
Credit card balances. Current statement balance, not credit limit. Even if you pay in full every month, list whatever you owe right now. People who pay in full will see this fluctuate but it averages out across quarters.
Personal loans. Current balance on any installment loans (debt consolidation, family loans you intend to repay, BNPL balances if material).
HELOC and home equity loans. Current drawn balance, not the full available credit line.
Medical debt. Any outstanding medical bills. Often forgotten because it doesn't feel like "real debt," but it absolutely is.
Other. Tax debt, business debt you're personally liable for, court-ordered judgments. Don't count: future obligations that aren't yet owed (like your kid's future college bills), monthly bills (rent, utilities, insurance) since those are operating expenses not debt.
A common error: subtracting expected interest from the principal. Don't. Net worth uses today's balance only. The interest is captured month by month as you pay it down.
Why Net Worth Matters More Than Income
Income is what you earn. Net worth is what you've kept. They are completely different numbers and they don't move together.
Two examples make this concrete. Person A earns $200,000 a year, drives a leased $80K SUV, has a $4,000/month mortgage on a stretched-budget house, $30K in credit card debt, $15K in a 401(k), and $2K in checking. Their income is impressive; their net worth is roughly negative $25,000 once you subtract liabilities. Person B earns $75,000 a year, drives a paid-off 2018 Honda, has a 15-year mortgage with a manageable payment, no consumer debt, $180K in retirement accounts, and $40K in HYSA. Their income is modest; their net worth is approximately $300,000.
Person B is winning. By a lot. And nobody at the office knows.
The median US household had a net worth of approximately $192,000 as of the most recent Federal Reserve survey, against a median household income around $70,000. The ratio of net worth to income for a typical household is roughly 2-3x. If yours is meaningfully lower than that, you're spending more than the average; if it's meaningfully higher, you're saving more than the average. Neither is "right" or "wrong," but both are useful information.
Net worth also exposes lifestyle inflation in a way nothing else does. A 30% raise often produces zero net worth growth because the new income gets absorbed into bigger rent, nicer car, more travel. The raise looks like progress on a paycheck. The net worth chart looks flat. Six months of looking at a flat chart is usually enough to change behavior.
Income matters too, of course — it's the engine that creates net worth. But once you're earning enough to cover essentials, the marginal dollar of income matters far less than the marginal percentage you save. A retirement calculator makes this dynamic vivid: someone who saves 20% of $80K beats someone who saves 5% of $200K to a comfortable retirement, every time.
Tracking Net Worth Over Time
Calculating it once is interesting. Tracking it is what produces behavioral change.
The simplest method is a spreadsheet with one column per quarter. Each row is an asset or liability category. Each cell is the balance on the last day of that quarter. The bottom row is the net worth total. Open it on the first weekend of each quarter, update the balances, save. That's it. After two years you'll have eight data points, and a chart drawn from those points tells you, brutally honestly, whether your financial trajectory is going where you want it.
Frequency matters. Weekly is too often (the noise overwhelms the signal). Annually is too rare (you won't notice problems until they're hard to fix). Monthly is fine but tedious. Quarterly is the sweet spot for most people: frequent enough to catch trends, infrequent enough to actually do.
Three numbers worth tracking alongside the headline net worth figure:
Net worth change quarter over quarter. Is it positive? By how much?
Savings rate. Total contributions to retirement and brokerage accounts divided by gross income. Anything above 15% is good; above 25% is exceptional.
Liability ratio. Total liabilities divided by total assets. A ratio above 50% means most of what you own is owed to someone else; below 25% means you have meaningful equity. Either is fine in different life stages, but the trend should be downward over time as a percentage of assets.
For people working toward specific milestones, pair net worth tracking with goal-specific math. If you're saving for a major purchase, a savings goal calculator tells you whether your current monthly savings will hit the target on time. If they don't, you can adjust before another year goes by.
The two most common mistakes in tracking: changing methodology midway (don't switch from "house at Zillow value" to "house at appraisal value" partway through), and counting bonuses or RSU vests in the quarter they happen as if they were ongoing income. Be consistent and use the same approach every time. Imperfect consistent data beats perfect inconsistent data every time.
FAQ
Q: Should I include my house in net worth? A: Yes, at current market value. Some people prefer to track "investable net worth" separately, which excludes home equity because you can't easily spend it. Both numbers are useful. Total net worth is the standard headline figure.
Q: What's a good net worth for my age? A: A common rule of thumb is age × pretax income ÷ 10. So a 35-year-old earning $80K should have ~$280K net worth. This is aggressive; most actual households are below it. The more useful question is whether your number is growing year over year, not whether it matches a benchmark.
Q: Do I count my car as an asset or just a liability? A: Both, separately. The car's current trade-in value is an asset. The remaining loan balance is a liability. If the loan exceeds the value (you're "underwater"), the car contributes negatively to net worth.
Q: Should I count my partner's net worth in mine? A: If finances are joined, calculate household net worth combining both. If finances are separate, calculate each individually. Combined household tracking is more common and usually more useful for joint goal-setting.
Q: My net worth went down this quarter — should I worry? A: Not necessarily. Investment account values fluctuate with markets; a drop driven by a stock market correction is noise, not signal. A drop driven by your spending exceeding your income is signal. Look at why it moved before reacting. Falls in market value during accumulation years are fine; falls due to overspending need attention.
The Short Version
Net worth = assets minus liabilities. List everything you own at current value, list everything you owe at current balance, subtract. Do it on the last day of each quarter, store the number, and keep going. The chart you build over five years will tell you more about your real financial life than any income statement ever could. If the line is going up over multi-year time horizons, you're winning regardless of what the absolute number is. If it's flat or going down despite a healthy income, the leak is somewhere in your spending — and net worth is the most honest signal you have to find it.
