Net Worth Calculator

Calculators · Added 15 August 2026

Add up what you own, subtract what you owe, and you have your net worth — the single number that describes your financial position. The arithmetic is trivial; the value is in the checklist, because the usual error is forgetting a liability rather than getting the subtraction wrong.

What you own — assets

Everything immediately spendable

Savings accounts, fixed deposits, emergency fund

Shares, funds, bonds, crypto — at today's value

Pension, 401(k), EPF, PPF — current balance

Home and any other real estate, at market value

Resale value, not what you paid

Your share of a business you own

Jewellery, collectibles, money owed to you

What you owe — liabilities

Outstanding balance, not the original loan

What is still owed on any financed vehicle

Remaining balance

Current balances, including anything on a 0% offer

Bank loans, family loans, buy-now-pay-later

Any assessed tax not yet paid

Anything else you are contractually obliged to repay

How to use the net worth calculator

  1. 1Fill in each asset category — leave anything that does not apply blank.
  2. 2Enter property and vehicles at what they would sell for today, not what you paid.
  3. 3Fill in each liability with the outstanding balance, not the original loan amount.
  4. 4Read the net worth figure, which updates as you type.
  5. 5Open the breakdown to see which items dominate each side.

Examples

Early career

Input
£8,000 savings · £3,000 car · £22,000 student loan
Result
Net worth −£11,000

Negative net worth is normal early on and is not a sign of failure.

Mid-life with a mortgage

Input
£320,000 home · £85,000 pension · £15,000 cash · £210,000 mortgage
Result
Net worth £210,000

Most of it is home equity and pension, neither of which is easily spendable.

Debt-to-asset ratio

Input
£420,000 assets · £210,000 liabilities
Result
50% — half the assets are financed by borrowing

The ratio adds context that the net worth figure alone does not.

About the net worth calculator

What net worth measures, and what it does not

Net worth is a stock, not a flow. It describes what you have accumulated at a moment in time, and says nothing about income, spending or whether either is sustainable. A high earner who spends everything can have a lower net worth than a modest earner who has saved consistently for twenty years, and both figures are accurate.

It also treats all assets as equivalent when they are not. A hundred thousand in a savings account and a hundred thousand of home equity contribute identically to the total, but only one of them can pay a bill next week. This is why liquidity deserves attention alongside the headline figure — a large net worth concentrated in illiquid assets can coexist with genuine short-term difficulty.

The debt-to-asset ratio this calculator reports alongside the total is a partial corrective. Two people with identical net worth, one holding £50,000 free and clear and the other holding £1,000,000 against £950,000 of borrowing, are in very different positions, and only the ratio distinguishes them.

The categories exist because people forget things

The arithmetic here is one subtraction, so the tool's value is entirely in the prompting. The consistent pattern in personal balance sheets is that assets are remembered and liabilities are not — the house comes to mind more readily than the outstanding balance on it, and small recurring debts are systematically overlooked.

The categories most often missed are buy-now-pay-later balances, money borrowed informally from family, tax owed but not yet paid, and the remainder on a phone or furniture finance agreement. None is large individually; together they routinely add up to several thousand, and leaving them out produces a flattering figure that is simply wrong.

On the asset side the common omission is the opposite kind of error: including things that would not realistically convert to money. Furniture, clothing and most consumer goods have negligible resale value and are better left out entirely. A net worth calculated with a generous valuation of household contents is measuring optimism rather than position.

Using the number well

The single most useful thing about net worth is that it captures both sides of the ledger at once. Paying down debt and accumulating savings both increase it, which makes it a fairer measure of progress than either savings or debt alone. Someone who clears £10,000 of credit card debt in a year has done as much for their position as someone who saved £10,000, and only net worth records both equally.

Tracked annually, it also exposes patterns that monthly budgeting misses. A year where income rose and net worth did not is a specific, answerable question. So is a year where the figure rose entirely because a house was revalued upward — real, but not the result of anything you did, and not something to rely on repeating.

What it should not become is a target in itself, particularly when compared against other people. Net worth varies enormously with age, country, housing market and career stage, and the comparisons circulating online are mostly noise. The only genuinely informative comparison is against your own figure from a year ago.

Frequently asked questions

Is negative net worth a problem?
Not necessarily, and it is extremely common. Anyone with student loans and few assets starts negative, as does anyone who has recently bought a home with a small deposit. What matters is the direction of travel over time rather than the sign at any one moment. Negative and improving each year is a healthy position; positive and deteriorating is not.
Should I include my pension?
Yes — it is an asset you own, even though you cannot access it yet. Enter the current balance rather than a projected value at retirement. For a defined-benefit pension there is no balance as such, which is one of the genuine limitations of a simple net worth figure; some people enter a transfer value if they have one, and others leave it out and note it separately.
How should I value my house and car?
At what they would realistically sell for today, not what you paid and not what you hope. For a house, a recent comparable sale on your street is a better guide than an online estimate. For a car, a trade-in or private sale value from a used-car guide is realistic. Overstating either inflates net worth without changing anything real, which defeats the purpose of measuring it.
How often should I calculate it?
Once or twice a year is plenty. Net worth moves slowly and is dominated by asset values that are themselves estimates, so checking monthly mostly measures noise. Annual figures on the same date each year make the trend legible, which is the only thing this number is genuinely good for.
Is anything I enter saved?
No. This runs entirely in your browser, nothing is transmitted anywhere, and nothing is written to your device. Close the tab and the figures are gone — which also means you need to record them yourself if you want to compare against next year.
