Net worth is the single most important number in personal finance. Unlike income — which tells you how much you earn — net worth tells you where you actually stand financially. It is the sum of everything you own minus everything you owe. A high income with high debt and no savings produces a low net worth. A modest income with disciplined saving and investing over decades can produce a high net worth. This complete guide explains how to calculate your net worth, what assets and liabilities to include, how to compare your net worth to national averages in the UK and US, and the most effective strategies for building wealth over time.
Net Worth = Total Assets − Total Liabilities
If your assets total £400,000 and your liabilities total £180,000, your net worth is £220,000. If your debts exceed your assets, you have a negative net worth — sometimes described as "being in the hole." Negative net worth is common among young people with student loans and no significant assets, and it is recoverable with a systematic debt reduction and savings plan.
Assets are everything of financial value that you own:
Liabilities are all your debts and financial obligations:
The UK Office for National Statistics (ONS) publishes household wealth data through the Wealth and Assets Survey (WAS). The most recent data shows median total household wealth by age of household reference person:
| Age Group | Median Total Household Wealth (UK) |
|---|---|
| 16–24 | ~£8,000 |
| 25–34 | ~£47,000 |
| 35–44 | ~£125,000 |
| 45–54 | ~£197,000 |
| 55–64 | ~£266,000 |
| 65–74 | ~£307,000 |
| 75+ | ~£248,000 |
Note that UK wealth is heavily influenced by homeownership and pension wealth. Household wealth includes property, pension funds, physical assets (vehicles, valuables), and net financial wealth. These are household figures — for individual net worth, the figures would typically be lower. The very high inequality in UK wealth distribution means the mean is significantly higher than the median — the top 10% hold approximately 43% of all household wealth.
The US Federal Reserve publishes the Survey of Consumer Finances (SCF) every three years. The 2022 SCF provides the most recent data on median and mean family net worth by age:
| Age Group | Median Net Worth (US) | Mean Net Worth (US) |
|---|---|---|
| Under 35 | $39,000 | $183,000 |
| 35–44 | $135,000 | $549,000 |
| 45–54 | $247,000 | $975,000 |
| 55–64 | $365,000 | $1,566,000 |
| 65–74 | $410,000 | $1,794,000 |
| 75+ | $335,000 | $1,624,000 |
The dramatic gap between median and mean net worth in the US reflects extreme wealth concentration: the top 1% of families hold approximately 30% of all US household wealth. For benchmarking purposes, the median is the more relevant comparison for most people.
Income and net worth are related but distinct. A high income helps build net worth — but only if a meaningful portion is saved and invested. Someone earning £150,000 a year but spending £148,000 a year builds minimal net worth. Conversely, someone earning £40,000 a year who saves 20% and invests consistently can build substantial net worth over 20–30 years through the power of compound growth.
The concept of HENRY (High Earner Not Rich Yet) — popularised in US financial media — describes high-income individuals (typically earning $150,000–$500,000/year) with high expenses and modest accumulated wealth relative to their income level. HENRYs are common in expensive cities (London, New York, San Francisco) where high living costs and social pressure to maintain a certain lifestyle consume most of high incomes.
A "millionaire" is generally defined as a person with a net worth of £1 million (UK) or $1 million (US). However, the meaning of this threshold varies significantly by context. In London and other expensive UK cities, £1 million in net worth may be largely tied up in home equity, leaving relatively modest liquid investment wealth. A £1 million net worth in Northern England or Scotland represents significantly different financial freedom than in London.
In the US, having $1 million in investable assets (excluding primary home equity) is a more meaningful wealth threshold. According to the 2022 Federal Reserve SCF, approximately 12–13% of US families have a net worth over $1 million. In the UK, the HMRC Wealth in Great Britain report suggests approximately 2–3% of adults have a net worth over £1 million when including all asset types.
Building net worth follows three fundamental principles:
Negative net worth — where debts exceed assets — is common and recoverable. Priorities for recovery: first, build a small emergency fund (£1,000–£2,000 / $1,000–$2,000) to avoid new debt from unexpected expenses. Then, pay down high-interest debt aggressively using the debt avalanche method (highest interest rate first) or debt snowball (smallest balance first for psychological wins). As debt falls, redirect the freed-up cash flow into savings and investments to begin building positive net worth.
In the UK, free debt advice is available from Citizens Advice, StepChange, and the National Debt Line. In the US, non-profit credit counselling is available through the National Foundation for Credit Counseling (NFCC).
Net worth is everything you own (assets) minus everything you owe (liabilities). Assets include cash, savings, investments, property, vehicles, and pension funds. Liabilities include mortgages, loans, credit card balances, and any other debts. Net Worth = Total Assets − Total Liabilities. A positive net worth means your assets exceed your debts; negative means your debts exceed your assets.
Based on ONS Wealth and Assets Survey data, UK median household wealth is approximately £47,000 for the 25–34 age group, £125,000 for 35–44, £197,000 for 45–54, and £266,000 for 55–64. These are household figures including property and pension wealth. The UK has very high wealth inequality, so these medians are more representative of most people than the much higher mean figures.
According to the 2022 Federal Reserve Survey of Consumer Finances, median US family net worth is approximately $39,000 under 35, $135,000 for 35–44, $247,000 for 45–54, $365,000 for 55–64, and $410,000 for 65–74. Mean figures are much higher due to wealth concentration at the top. The median is the more relevant benchmark for most families.
Yes. Pension wealth is often the largest single asset for working-age adults. In the UK, defined contribution pension fund values can be obtained from your pension provider. For defined benefit pensions, a rough calculation is annual pension entitlement × 20 for an approximate transfer value. State pension entitlement is generally not included in personal net worth calculations. In the US, 401(k) and IRA balances should be included at their current value.
Include the current market value of your home (use a realistic current estimate, not the purchase price) as an asset, and the outstanding mortgage balance as a liability. The difference — your home equity — represents your net property wealth. In the UK, Rightmove and Zoopla provide indicative property valuations; in the US, Zillow and Redfin offer estimates.
HENRY stands for "High Earner Not Rich Yet." It describes individuals with high incomes (typically £80,000–£250,000 / $150,000–$500,000 per year) but relatively modest net worth due to high living costs, lifestyle inflation, or insufficient saving and investing. HENRYs have the means to build significant wealth but have not yet converted high income into high net worth through disciplined financial habits.
This depends heavily on context, but commonly: net worth over £100,000 is considered comfortable; £500,000+ is considered prosperous; £1 million+ is millionaire status. However, in high-cost areas like London and the South East, £1 million may be substantially tied up in property. Liquid investable wealth (pension funds + investment accounts, excluding primary home) is often a more meaningful measure of financial security.
The fastest net worth improvements come from: (1) eliminating high-interest debt (reducing liabilities directly); (2) increasing savings rate and investing in index funds (building assets); (3) maximising employer pension contributions to capture "free money" from employer matching; (4) using tax-advantaged accounts (ISA in UK, Roth IRA/401k in US) to protect investment growth from tax erosion. Income growth also helps, but only if the additional income is saved rather than spent.
