What net worth is
Net worth is one of the simplest numbers in personal finance: everything you own minus everything you owe. Total up your assets, cash, investments, property, pension, vehicles, then subtract your liabilities, which are your debts. What’s left is your net worth. It’s a snapshot, not a score: it captures where you stand today, and it moves every time you save, spend, invest or pay down debt.
A positive net worth means your assets outweigh your debts. A negative one is common early on, a fresh mortgage or student loan can outweigh what you’ve built so far, and it isn’t a failure. The useful thing is the direction of travel over months and years, not any single reading.
How to calculate your net worth
The formula is simple: net worth = total assets minus total liabilities. Add up everything you own (property, savings, pensions, investments, vehicles), add up everything you owe (mortgage, loans, credit cards, student loan), and take the second total off the first. The figure left over is your net worth, and the calculator above does the arithmetic once you enter your figures.
What to include as assets and liabilities
Assets are anything you own with real, sellable value: cash and savings, investments like shares and funds, the current market value of property, the balance of your pension or superannuation, and vehicles. Use realistic present-day values rather than what you paid or hope to get.
Liabilities are what you owe: your outstanding mortgage, personal and car loans, credit card balances, student loan, and any other debts. Include your home’s full value as an asset and the mortgage as a liability, so only your equity feeds into the total. The calculator above lets you enter each category and does the arithmetic for you, in your chosen currency.
What’s a good net worth by age?
This is the question everyone asks, and the honest answer is: it depends. Income, cost of living, where you live, whether you own property and how far you are from retirement all pull the “normal” number around. As a very rough guide, net worth tends to rise with age, lower in your 20s and early 30s when student loans and a new mortgage weigh heaviest, then climbing through your 40s and 50s as debts shrink and pensions grow.
If you enter your age, the calculator compares your figure against the real median net worthfor your age band, and tells you whether you’re above, around or below the typical range. The benchmark switches with your currency, using each country’s national wealth survey. For the UK, the ONS Wealth and Assets Survey puts median household net wealth at around £77,000 for households headed by a 25 to 34 year-old, £198,000 at 35 to 44, £367,000 at 45 to 54, £556,000 at 55 to 64, and £468,000 at 65 and over (Great Britain, 2018 to 2020, including private pensions).
Change the currency and the source changes with it: US figures come from the Federal Reserve Survey of Consumer Finances (2022), Australia from the ABS Survey of Income and Housing (2019 to 2020), Canada from the Statistics Canada Survey of Financial Security (2023), the euro area from the ECB Household Finance and Consumption Survey (2021), and New Zealand from Stats NZ (year to June 2024).
Average net worth in the UK by age
For a UK reference point, the ONS Wealth and Assets Survey reports median household net wealth by the age of the household head (Great Britain, 2018 to 2020, private pensions included):
- 25 to 34: around £77,000
- 35 to 44: around £198,000
- 45 to 54: around £367,000
- 55 to 64: around £556,000
- 65 and over: around £468,000
These are household figures, not individual, and they lag because the survey runs only every few years, so read them as a rough reference rather than a target. Median is the midpoint, half of households sit above and half below, which is a fairer gauge than an average that a few very wealthy households would drag upwards.
How to use this calculator
- Pick your currency from the switcher at the top.
- Enter the current value of each asset you own, leave anything that doesn't apply blank.
- Enter what you owe across each liability: mortgage, loans, cards, student loan and any other debts.
- Read your net worth, plus totals for assets and liabilities and a breakdown of what your assets are made of.
- Optionally add your age to see how you compare against a rough, indicative median for your age band.
