Net worth calculator

Net worth is your assets minus your debts. The calculator adds up what you enter in each category, takes away mortgages, cards, loans and (if you choose) your student loan, and shows the result three ways: in total, by category, and by when you could reach the money.

Accessible now is cash, ISAs, shares outside an ISA and crypto: things you could sell or withdraw within days. Locked until pension age is every pension, which you can't normally draw before 55 (57 from April 2028). Tied up in property is the value of your home and any other property, before the mortgage.

The comparison uses the ONS Wealth and Assets Survey for April 2020 to March 2022, published January 2025, which is the latest release. It measures household total wealth: net property, private pensions, net financial wealth and physical wealth such as cars and contents. It doesn't include the State Pension, so neither does this comparison.

This calculator assumes the figures you enter are today's values and doesn't estimate anything for you, apart from the optional rule of thumb for defined benefit pensions.

The rule is simple: anything you could sell or that pays out to you is an asset, and anything you have to pay back is a debt. A few UK items need a decision.

Pensions

A workplace pension or SIPP has a pot value on its latest statement: use that. A defined benefit (final salary) pension pays an income instead, so its value is an estimate. One rough guide is 20 times the yearly pension built up so far, the factor HMRC used to test these pensions against the old lifetime allowance. Leave it at zero if you would rather keep the figure to money that has a balance.

Property

Enter what your home would sell for, not what you paid, and the mortgage balance from your latest statement. Your equity is the difference. If you rent, this is zero, and the comparison below will read lower than for homeowners of the same age: property and pensions make up 40% and 35% of all household wealth in Great Britain.

Student loans

A Plan 2 or Plan 5 loan behaves more like a graduate tax than a debt: repayments depend on income, and what's left is written off after 30 or 40 years. If you don't expect to repay it in full, leaving it out gives a truer picture of what you will actually pay. If you expect to clear it, count it.

Cars, valuables and businesses

Count them at what they would fetch today, which for a car is usually well under what it cost. Include car finance under loans so a financed car doesn't count twice in your favour.

The Wealth and Assets Survey asks a large sample of households about everything they own and owe. In April 2020 to March 2022 median household total wealth in Great Britain was £293,700. By age of the household reference person, it rises to a peak in the 65 to 74 band, then falls as people spend their savings in retirement.

A median is the middle household: half have more, half less. The mean is much higher because a small number of very wealthy households pull it up, so the median is the fairer benchmark. The figures are from 2020 to 2022 and haven't been adjusted since; house prices and pension values have moved since then. The ONS also changed how it values pensions in this round and suspended the survey's accredited status while it improves quality, so read the comparison as a rough guide rather than a precise rank.

To see where a figure sits beyond the median, with the top 10% and top 1% thresholds for your age, try the net worth percentile calculator.

A single figure is a snapshot. What matters more is the direction: whether debts are shrinking and pensions and savings growing. Many people recalculate monthly or quarterly, using the same method each time so the changes are real rather than a different way of counting. Update property values once or twice a year; they move slowly and an estimate is all anyone has until you sell.
