Net worth is the single number that best summarises your financial position, and most people have never calculated theirs. It's simple arithmetic — everything you own minus everything you owe — but it captures something income can't. A surgeon earning $400,000 with $600,000 of debt and no savings is in a weaker position than a teacher earning $55,000 with a paid-off house. Income tells you what's flowing through your hands; net worth tells you what stayed.
The definition
Net worth = total assets − total liabilities. Assets are things you own that have monetary value. Liabilities are debts you owe. Subtract the second from the first and you have your net worth, which may well be negative — and often is, early in adult life. The number itself matters less than its direction over time.
What counts as an asset
Use current market value, not what you paid. The rule is what you could realistically sell it for today, in a reasonable timeframe, not the optimistic figure.
- Cash: checking accounts, savings accounts, cash ISAs, physical cash.
- Investments: brokerage accounts, index funds, individual shares, bonds, crypto at current value.
- Retirement accounts: 401(k), IRA, workplace pensions — count the current balance even though access is restricted.
- Property: your home and any rental or land, at realistic market value rather than a Zillow high estimate.
- Vehicles: cars, motorcycles, boats, at trade-in value, which is usually well below what you feel they're worth.
- Other valuables worth counting only if genuinely substantial and sellable: jewellery, collectibles, a business stake.
Leave out furniture, clothes, electronics and household goods. They depreciate steeply, you'd never sell them, and including them inflates the number without telling you anything useful.
What counts as a liability
Use the current payoff balance, not the original loan amount and not the monthly payment.
- Mortgage — the outstanding balance, which will be lower than what you borrowed.
- Car loans and personal loans, at current balance.
- Credit cards — the full balance, including anything on a 0% promotional period.
- Student loans, at current balance.
- Medical debt, tax owed, buy-now-pay-later balances, and money owed to family.
How to calculate yours
This takes about ten minutes if your statements are to hand. List every asset with its current value and add them up. List every debt with its current balance and add those up. Subtract the second total from the first. The net worth calculator does the arithmetic and keeps assets and liabilities in separate columns, so you can see both totals alongside the result — everything stays in your browser, and nothing is stored or transmitted.
A worked example
Take a household with $12,000 in cash and savings, $35,000 in retirement accounts, a home worth $280,000 and vehicles worth $15,000 — total assets of $342,000. Against that: a $210,000 mortgage, a $9,000 car loan and $3,000 on credit cards, for total liabilities of $222,000. Net worth is $120,000.
Notice how much of that sits in the home. That's typical, and it's worth understanding rather than celebrating uncritically: home equity is real wealth, but it isn't liquid, and you can't spend it in an emergency without borrowing against it or selling. A high net worth concentrated in property can coexist with genuine cash-flow stress, which is why net worth is a companion to your emergency fund rather than a substitute for it.
What counts as a "good" net worth?
Comparisons to national averages are mostly unhelpful, because averages are skewed upward by extreme wealth and vary enormously by age, region and property market. A more useful benchmark is your own trajectory: is the number higher than it was a year ago, and is the gap between assets and liabilities widening? A rough rule of thumb some people find motivating is aiming to reach roughly your annual salary in net worth by around thirty and several times it by fifty, but treat that as a loose signpost rather than a target to feel bad about. Someone who's just funded a professional qualification and someone who's been earning steadily for a decade are not on the same clock.
Why negative net worth is normal early on
If you finished a degree with student loans, bought a car on finance, or have a new mortgage on a house that hasn't appreciated yet, your net worth is probably negative. This is unremarkable and not a sign of failure. Student debt in particular is a liability today against an asset — your earning capacity — that never appears on the balance sheet. What matters is whether the number is moving in the right direction each year. Going from −$45,000 to −$32,000 is a genuinely good year, and it should feel like one.
How often to track it
Quarterly is plenty, and annually is fine. Monthly tracking mostly measures market noise and property estimate wobble, and invites you to react to movements that don't mean anything. Pick a consistent date, use the same valuation method each time so the comparison is honest, and record the figure somewhere you'll still have it in five years. The value of net worth as a metric comes almost entirely from the trend line, and a trend needs a history.
How to grow it
There are only two levers — increase assets or decrease liabilities — and only a handful of effective ways to pull them.
- Widen the gap between what you earn and what you spend; that surplus is the raw material for everything else.
- Pay down high-interest debt, which raises net worth dollar-for-dollar and removes a compounding drag.
- Contribute consistently to retirement accounts, especially up to any employer match, which is an immediate return you can't get elsewhere.
- Avoid depreciating assets bought with debt — financing a new car is one of the most reliable ways to hold net worth flat.
- Let time and compounding work; the largest gains in most people's net worth come from decades, not from any single decision.
Net worth vs income: why the distinction matters
Income is a flow and net worth is a stock, and confusing the two leads to some of the most common financial mistakes. A pay rise increases your income immediately but does nothing for your net worth unless some of it survives the month. Lifestyle inflation — the tendency for spending to expand to match earnings — is precisely the mechanism by which a rising income produces a flat net worth, and it's why high earners with nothing saved are far more common than people expect.
The practical test is simple: if your income doubled and your net worth didn't move over the following two years, the extra money went to consumption rather than to your position. That isn't automatically wrong — spending money is the point of having it — but it should be a choice you made rather than one that happened to you.
What net worth doesn't tell you
It's a snapshot, not a full picture. It says nothing about your cash flow, whether your assets are accessible, how secure your income is, or whether you're insured against disaster. Someone with a $500,000 net worth entirely in home equity and a pension, no emergency fund and unstable self-employed income is more fragile than the number suggests. Track net worth alongside your savings rate and your emergency fund coverage, and you'll have a reasonably complete view.
The bottom line
Net worth is assets minus liabilities, measured at current values. Calculate it in ten minutes with the net worth calculator, exclude depreciating household items, use payoff balances rather than monthly payments, and check it quarterly. Judge it by its direction rather than against anyone else's number, and remember that a negative figure early in adult life is normal.
