The average net worth at 40 in the UK is around £320,000, but the median — which better reflects most people’s reality — is closer to £175,000. At this age, at 40, property equity and pension savings drive most wealth. Those who bought homes in the 2010s have seen significant equity growth. Net worth figures vary enormously based on home ownership, career stage, and pension contributions.
Average Net Worth at 40 — Key Figures
| Metric | Amount |
|---|---|
| Median total net worth | £175,000 |
| Mean (average) total net worth | £320,000 |
| Median financial wealth (savings/investments) | £10,000 |
| Median property net wealth (equity) | £105,000 |
| Median private pension wealth | £70,000 |

The gap between the mean and median is large because a relatively small number of high-wealth individuals — those who inherited significant assets, sold businesses, or built substantial investment portfolios — pull the average upward substantially.
How Net Worth Breaks Down at 40
At 40, net worth typically consists of three main components:
| Component | Typical median | Notes |
|---|---|---|
| Property equity | £105,000 | Only for homeowners; renters have £0 here |
| Pension savings | £70,000 | Workplace and private pensions combined |
| Financial wealth | £10,000 | Cash savings and investments (ISAs, etc.) |
The Homeowner vs Renter Divide
Property ownership creates the biggest split in net worth at any age. A 35-year-old who bought a home in 2016 with a 10% deposit on a £200,000 property may now have £80,000–£120,000 in equity. A renter the same age with identical income has no property equity — but may have higher savings and flexibility.
Net worth benchmarks should always be considered alongside your housing situation. Renting is not financial failure; it is a different asset allocation.
Net Worth Distribution at 40
| Percentile | Approximate net worth |
|---|---|
| Bottom 25% | Below £70,000 |
| Median (50th percentile) | Around £175,000 |
| Top 25% | Above £350,000 |
| Top 10% | Above £700,000 |
Worked Example
Sarah is 40 years old and lives in Manchester. She owns a flat worth £220,000 with a £140,000 mortgage outstanding — so £80,000 in property equity. She has £12,000 in a Stocks and Shares ISA, £8,000 in cash savings, and a workplace pension pot worth £70,000. She has a £4,000 car finance balance outstanding.
Her net worth: £80,000 + £12,000 + £8,000 + £70,000 − £4,000 = £166,000
This puts her around the median for her age group.
What Should You Focus on at 40?
Building Foundations
Maximise pension contributions. The workplace pension you may have been contributing to for 5–10 years is building meaningfully. Consider a SIPP to supplement if you are self-employed or want more control. ISA discipline. Use your annual ISA allowance (£20,000) — especially Stocks and Shares ISAs for long-horizon saving. Mortgage overpayment consideration. Overpaying your mortgage builds equity faster, but weigh this against ISA and pension returns.
How to Increase Your Net Worth
The formula is straightforward even if execution is difficult:
- Earn more — career progression, side income, upskilling
- Spend less — budgeting, reducing fixed costs, conscious consumption
- Invest the difference — pension, ISA, and over time, property
- Avoid wealth destroyers — high-interest debt, unnecessary fees, emotional investment decisions
