Net Worth Calculator

Use the net worth calculator above

Pop your figures into the tool above and it does the sums for you. List what you own (assets) and what you owe (liabilities), and it returns your net worth plus a simple breakdown. The more honest and complete your inputs, the more useful the result - round-number guesses give you a round-number answer.

How to calculate net worth

The formula could not be simpler:

Net worth = total assets − total liabilities

Assets are everything you own that has a cash value. Liabilities are everything you owe. Subtract one from the other and you have your net worth. It can be positive (you own more than you owe) or negative (you owe more than you own) - and a negative figure in your twenties or thirties is completely normal if you are carrying a mortgage or student debt.

When you add up your assets, include:

• Cash in current accounts, savings accounts and Premium Bonds
• ISAs, shares, funds and any investment platform balances
• Pension pots - workplace, personal and SIPP (use the current transfer value)
• Your home, valued at what it would realistically sell for today
• Other property, including buy-to-lets
• Vehicles worth selling, and any high-value possessions you could actually liquidate

When you add up your liabilities, include:

• The outstanding mortgage balance (not the original loan)
• Credit card balances and overdrafts
• Personal loans, car finance and Buy Now Pay Later balances
• Your remaining student loan

A quick word on the student loan. For most UK graduates it behaves more like a graduate tax than a normal debt - repayments are 9% of income above a threshold and the balance is written off after a set period. Many people leave it out of their net worth for that reason. There is no single right answer; just be consistent so your figure means the same thing each time you check it. You can see how repayments work with the student loan repayment calculator.

Worked example: a couple in their thirties

Take Priya and Tom, both 34, who have just had their second child and want to know if they are actually getting anywhere. Here is what they own:

• Home value: £310,000
• Combined pensions: £48,000
• Stocks and shares ISA: £14,500
• Cash savings: £9,000
• Car (realistic resale): £6,500

Total assets = £310,000 + £48,000 + £14,500 + £9,000 + £6,500 = £388,000.

Now what they owe:

• Mortgage outstanding: £238,000
• Car finance: £7,200
• Credit card: £2,300

Total liabilities = £238,000 + £7,200 + £2,300 = £247,500.

Net worth = £388,000 − £247,500 = £140,500.

Notice the car: it is worth £6,500 but still has £7,200 of finance against it, so it is dragging their net worth down by £700 overall. That is the kind of insight a single number hides but the breakdown reveals.

Worked example: starting from below zero

Now take Jordan, 25, a year into their first graduate job. Assets: £1,800 in a current account and a £3,000 pension pot, so £4,800 in total. Liabilities (excluding the student loan, which Jordan chooses to leave out): a £1,500 overdraft and £4,000 on a credit card from setting up a flat, so £5,500.

Net worth = £4,800 − £5,500 = −£700.

A negative net worth looks alarming, but for Jordan it is a starting line, not a verdict. Clearing the credit card and overdraft over the next year - and the auto-enrolment pension quietly growing in the background - would flip that figure positive without any heroics. The point of tracking is to watch the line climb.

How to value the tricky assets

Your house and your pension usually make up most of your net worth, so getting them roughly right matters more than fussing over a sofa.

Your home: use a realistic selling price, not the optimistic number in your head. Check recent sold prices (not asking prices) for similar properties on your street via the Land Registry. If you might sell, remember the costs that eat into the equity - see the cost of moving house calculator for agent and legal fees.

Your pension: use the current fund value or transfer value, which your provider shows on your statement or app. For a defined-benefit (final salary) scheme there is no pot, so use the cash-equivalent transfer value if you have one, or simply note the promised income separately. The pension pot calculator helps you project where a defined-contribution pot is heading.

Cars and possessions: only count what you would genuinely sell. A car loses value the moment you drive it off the forecourt, so use a current resale estimate, not what you paid. Skip the jewellery, gadgets and furniture unless an item is worth enough to realistically sell.

What is a good net worth in the UK?

There is no official pass mark, and comparing yourself to a national average is mostly noise - a 28-year-old renter and a 58-year-old homeowner are in completely different chapters. A more useful test is whether your own number is trending upward year on year, and whether your assets are working assets (investments, pensions, property equity) rather than depreciating ones (cars, gadgets).

One practical milestone often used in personal finance: aim to have roughly one year's salary saved or invested by your early thirties, building towards several times your salary by retirement. Treat these as rough waypoints, not rules. The MoneyHelper service, backed by the government, has free guides on building savings and pensions at moneyhelper.org.uk.

How to grow your net worth

Net worth moves in two directions at once: you can grow assets and shrink liabilities. The fastest wins usually come from the liability side, because clearing expensive debt is a guaranteed return.

• Kill high-interest debt first. A credit card charging 24% APR costs you far more than most investments earn. Paying it off is the highest-return move available to almost everyone.
• Capture free money. Workplace pension contributions come with employer matching and tax relief - turning down the match is leaving guaranteed money on the table.
• Use tax wrappers. An ISA shelters up to £20,000 a year from tax on growth and interest. The ISA calculator shows how that compounds.
• Overpay the mortgage when it makes sense. Every pound off the balance lifts your net worth directly and cuts future interest.
• Let time and compounding work. Long-term investing turns modest monthly contributions into serious sums; the compound interest calculator makes the effect obvious.

If you want a structured plan for where the money goes each month, the budget calculator helps you split income between spending, debt and saving.

Common mistakes when working out net worth

• Using the original loan, not the current balance. Your mortgage liability is what is left to pay today, which your annual statement shows.
• Over-valuing the house. Zoopla-style estimates and neighbour gossip inflate things. Use sold prices.
• Forgetting the pension. For many people it is their single largest asset, yet it is invisible day to day. Always include it.
• Counting an asset but not its debt. A £25,000 car on £22,000 of finance adds only £3,000 of net worth, not £25,000.
• Including things you will never sell. Counting your wardrobe and your TV pads the number without changing your real position.
• Checking it daily. Net worth is a slow-moving picture. Reviewing it every three to six months keeps you honest without the noise of market wobbles.

Does tax affect your net worth?

Your net worth is measured before tax, but tax can quietly reduce what some assets are really worth to you. Pension withdrawals are taxable as income (usually 25% can be taken tax-free, the rest taxed at your marginal rate). Selling shares or a second property can trigger Capital Gains Tax - for 2026/27 the annual exempt amount is £3,000, with gains taxed at 18% within the basic-rate band and 24% above it. Your main home is normally exempt under Private Residence Relief. Income Tax also differs in Scotland, which has its own rates and bands, so a Scottish taxpayer drawing a pension may keep a slightly different amount than someone in England, Wales or Northern Ireland. None of this changes today's net worth figure, but it is worth remembering when you plan to actually spend an asset. For the official Capital Gains rules, see gov.uk/capital-gains-tax.

These figures are estimates for guidance only and are not personal tax or financial advice. For decisions about pensions, tax or large purchases, speak to a qualified adviser.

Who should use this calculator

Net worth is assets minus liabilities — the single number that says most about financial position, and one most people have never actually calculated. It cuts through income entirely: a high earner with large debts can have a lower net worth than someone earning half as much.

Its real value is as a tracked figure rather than a snapshot. Measuring it once a year shows whether the direction is right, which is more useful than any individual month’s budget. The projection here extends that trend forward based on what you save and repay.

What this calculator assumes

• Net worth is total assets less total liabilities at today’s values.
• Assets grow at the rate entered; debts reduce by the repayments you set.
• Monthly saving is added to assets.
• Figures are nominal unless you deliberately use a real growth rate.

Limitations — what it does not cover

• Pension valuation. Defined-contribution pots have a value; defined-benefit schemes are an income promise with no simple capital equivalent.
• Illiquidity. Property and pensions dominate most balance sheets and cannot readily be spent.
• Property values, which are estimates until you sell, and selling costs.
• Tax on realisation — capital gains, or Income Tax on pension withdrawals.
• Inflation, which erodes the real meaning of a growing nominal figure.
• Depreciating assets such as cars, often counted at more than they are worth.
