Net Worth Calculator United Kingdom
This net worth calculator adds up your cash, investments, property and pensions, subtracts your debts and shows your net worth and the split.

What it does
The Net Worth Calculator shows what you are worth in a single figure: everything you own minus everything you owe. Enter your cash, investments, property, pensions and debts to see your total net worth and how it splits between assets and liabilities.
Data sources & parameters
This calculator uses standard financial formulas and runs entirely in your browser. It needs no external rate data — your result is computed only from the values you enter above.
We always strive to use the latest data for every variable so our results and reports are as accurate as possible. Even so, errors are possible — you should not rely on this tool or its report alone, and we accept no liability for any decision made based on it.
The formula
Total assets = cash + investments + property + pensions + other assets; total liabilities = mortgage + other debts; net worth = total assets − total liabilities
How it works
It adds up your assets — cash and savings, investments, property value, pension pots and any other assets — then subtracts your total liabilities, which is your mortgage plus any other loans and card balances. The difference is your net worth.
Where it is used
- Taking a yearly snapshot of your overall financial position
- Tracking whether your wealth is growing as debts fall
- Seeing how much of your assets are still owed to lenders
Worked example
With a £300,000.00 home plus cash, investments and pensions, your total assets come to …. After … of mortgage and other debt, your net worth is ….
Net worth answers a simple question: if you sold everything you own and paid off everything you owe, what would be left? This calculator adds up your assets and subtracts your liabilities to give that figure, with a breakdown of what you hold against what you still owe.
What net worth actually means
Net worth is not income. Someone on a high salary who spends it all can have a lower net worth than a careful saver on modest pay. It measures what you have built up, not what passes through your bank account: total assets minus total liabilities. Financial planners use it to track long-term progress because it is not distorted by month-to-month swings.
What counts as an asset
Assets are anything of value you own. The calculator groups them as cash and savings in current and savings accounts; investments such as Stocks and Shares ISAs, general investment accounts, shares and funds; the market value of property you own; and pension pots, which for many working people are among their largest assets. Use “other assets” for anything else worth a meaningful amount, such as a car you own outright, valuable jewellery or a stake in a business. Everyday possessions are usually left out because they lose value quickly and are hard to value.
What counts as a liability
For most homeowners the largest liability is the mortgage balance still to be repaid, not the original loan. “Other debts” covers personal loans, car finance, credit card balances, overdrafts and buy now pay later balances. Because you enter the full property value as an asset and the mortgage as a liability, the calculator nets them off and your home equity is reflected automatically.
A worked example
You have £20,000 in cash and savings, £30,000 in investments, a home worth £300,000 and £50,000 in pensions: £400,000 of assets. You owe £200,000 on the mortgage and £5,000 of other debts, £205,000 in total. Your net worth is £400,000 minus £205,000, or £195,000. The bar chart shows the assets bar next to the shorter liabilities bar, and the gap between them is your net worth.
Using the result to make decisions
The trend matters more than any single figure. Work it out on the same date each year. If it is rising, your saving and debt repayment are outpacing any falls in asset values. If it is flat or falling, check whether you are saving enough, whether debts are growing or whether an asset such as property has fallen in value.
Assumptions and limitations
This is a snapshot based only on the figures you enter, so it is as accurate as those values. Property and investment values change constantly, so treat the result as a point-in-time estimate. It does not allow for tax due if you sold assets, such as Capital Gains Tax on investments or a second property, or for early repayment charges on debts, so the amount you could actually realise may differ. Defined benefit pensions are hard to value and are best considered separately. For decisions with tax or estate planning consequences, speak to a qualified financial adviser.
