What you own minus what you owe. Two minutes to the most honest number in personal finance — calculated in your browser, uploaded nowhere.
Income feels like progress, but plenty of high earners are broke in slow motion. Net worth cuts through: it captures saving, debt, and asset growth in a single figure that either rises or doesn't. Checked quarterly, it is the feedback loop that tells you whether the year's financial decisions actually worked.
Only three things move net worth: spend less than you earn (the gap becomes assets), pay down debt (especially expensive debt — see the debt payoff calculator for the cheapest route), and let assets compound (the compound interest calculator shows what patience is worth). The first one funds the other two, and it is a budgeting problem — which is where a zero-based budget comes in.
One habit worth stealing: track net worth and celebrate the boring milestones — first time positive, first time above a year's salary. The number compounds slowly and then all at once, exactly like the interest table.
net worth = total assets − total liabilities. The calculator also shows liabilities ÷ assets, the share of what you own that is financed by debt.
| Assets | Liabilities | ||
|---|---|---|---|
| Current account | $2,000 | Credit card | $1,500 |
| Savings | $6,000 | Loan | $9,000 |
| Pension and investments | $15,000 | ||
| Total | $23,000 | Total | $10,500 |
Net worth is $23,000 − $10,500 = $12,500, and 46% of the assets are financed by debt.
Choose £ for the UK, or $ for Canadian and Australian dollars. Include the accounts you actually have: in the UK, workplace and personal pensions and ISAs; in Canada, RRSPs and TFSAs; in Australia, superannuation. Enter what each is worth today, and list mortgages, car finance, credit cards and student loans as liabilities.
Everything you own (assets: cash, savings, investments, pensions, property, vehicles) minus everything you owe (liabilities: mortgage, loans, credit cards, overdrafts). It is the single most honest one-number summary of your financial position.
It is common, especially early in adult life — a student loan or a new mortgage easily outweighs early savings. The number that matters is the direction: tracked quarterly, a rising net worth means your decisions are working, whatever the absolute figure says today.
Most people include both: pension pots at current value, the home at a realistic sale price with the outstanding mortgage as a liability. Some prefer a separate "liquid net worth" that excludes them. Either is fine — just be consistent between check-ins.
No. Everything is calculated in your browser on this page and disappears when you close the tab. Nothing is uploaded to any server.
Yes, if you own it: count its realistic sale value as an asset and the mortgage as a liability. Many people also track net worth without their home, to see the money that is not tied up in it.
Yes. It is an asset, though you cannot spend it until retirement age. Track your net worth with and without it if you want to see both the total and the money you can use sooner.
Quarterly is enough for most people. Use the same date each time and the same list of accounts, so the change from one quarter to the next is meaningful.
