How to Calculate Your Net Worth
Net worth is one subtraction: everything you own minus everything you owe. Here is how to gather the figures, avoid the usual mistakes and use the result.
· 4 min read

Your net worth is the single figure that answers a blunt question: if you sold everything you own today and paid off everything you owe, what would be left? The arithmetic is simple subtraction. The work lies in gathering honest numbers, and in resisting the urge to round in your own favour.
This guide walks through the calculation one step at a time, explains which items belong on each side, and suggests how to use the result without letting it rule your mood. It is general information, not financial advice; for decisions about your own money, speak to an independent adviser.
The formula in one line
Net worth = total assets − total liabilities.
Assets are things you own that have a money value. Liabilities are debts you are obliged to repay. If assets come out larger, your net worth is positive. If debts are larger, it is negative, which is common early in a career, after study or soon after buying a home, and is not a verdict on you as a person.
Step 1: list what you own
Start with the easiest items and work towards the ones that need estimating.
- Cash and savings: current accounts, savings accounts, cash at home. Use today's balances.
- Investments: funds, shares, bonds and similar holdings, at their current market value rather than what you paid.
- Retirement savings: pension or retirement account balances from your latest statement.
- Property: your home and any other real estate, at a realistic estimate of what it would sell for now.
- Vehicles: what a buyer would actually pay for the car in its current condition, not the sticker price you remember.
- Valuables: only items you could and would sell, such as jewellery or collectibles with a known resale market.
Leave out everyday belongings like furniture, clothes and kitchen gadgets. They have some resale value, but it is usually small and hard to pin down, and including them inflates the total without telling you much.
Step 2: list what you owe
Now the less comfortable half. Pull up statements and note the outstanding balance on each debt, not the monthly payment.
- Mortgage balance on each property
- Car loans or finance agreements
- Student loans
- Credit card balances, including any that are cleared monthly but have a balance today
- Personal loans, overdrafts and buy-now-pay-later plans
- Money owed to family or friends, if you intend to repay it
If a balance is uncertain, a quick call to the lender or a look at your online account usually settles it. Short-term borrowing deserves particular attention; our piece on responsible cash advance borrowing covers how those small sums can add up.
Step 3: subtract and write it down
Add each column, then take the liabilities total away from the assets total. A simple table on paper or in a spreadsheet is enough:
| Side | What goes here | Value to use |
|---|---|---|
| Assets | Cash, investments, retirement savings, property, vehicles | What it would fetch or is worth today |
| Liabilities | Mortgage, loans, cards, overdrafts, private debts | Outstanding balance today |
| Net worth | Assets minus liabilities | The figure you track over time |
Date the sheet. A single snapshot matters less than the line you draw by repeating it.
Common mistakes that skew the figure
Valuing things at purchase price
Cars, electronics and many other goods lose value from the moment you buy them. Use what someone would pay today.
Being optimistic about the house
A hopeful guess at the property value can swamp every other line. Base the estimate on recent sales of similar homes nearby, and consider knocking something off for selling costs.
Forgetting small debts
Store cards, deferred payment plans and an old overdraft are easy to overlook. Each one belongs on the list.
Counting income as an asset
Salary is not part of net worth until it lands in an account. Net worth measures what you hold, not what you earn.
How often to recalculate
Once or twice a year suits most households, perhaps at the start of the year or around a birthday. Checking more often tends to track market swings rather than your own habits. What you want to see over the long run is the direction: is the gap between assets and debts widening in your favour?
Using the number well
Net worth is a scorecard, not a plan. On its own it does not tell you whether you are saving enough or carrying the wrong kind of debt. It becomes useful when you ask what moved it:
- Did a debt balance fall because of regular repayments?
- Did savings grow because of steady contributions, or only because markets rose?
- Did a new loan or a big purchase pull the figure down?
Answering those questions points to habits worth keeping and ones to change. Paying down expensive debt and building a cash buffer often go together with a healthier credit record, which we cover in how to improve your credit score over time.
A note on comparisons
It is tempting to measure your figure against friends, colleagues or headlines. Ages, housing costs, family support and career paths vary so much that such comparisons rarely help. The fairest benchmark is your own figure from last year.
Keep the sheet somewhere safe, treat it as private, and update it with the same method each time so that the numbers stay comparable.
Odd jobs
Quick wins around the house and the drive
Little jobs that save a headache later on.
Date your money check
Write the date on every net worth or budget sheet so next year's version compares fairly.
Keep a gauge in the glovebox
A personal tire gauge costs little and is often steadier than a forecourt one.
Restart before you ring
Many picture freezes clear once the router and the box have been switched off and on again.
Read the door placard
Your car's correct tire pressures come from the maker, not from the sidewall.

A few principles that shape what reaches the page.
A vehicle handbook outranks any general car guide, ours included.
Credit scoring differs between countries and between agencies, so no single score explains every file.
Book values on a balance sheet can sit a long way from what an asset would actually sell for.
Apps and set-top boxes rearrange their menus often, which makes the provider's own help pages the freshest source.
A figure that depends on your lender, your car or your country is better looked up at the source than copied from an article.
