Net worth sounds like a phrase for people with offshore accounts and a portfolio manager. It isn’t. It’s just one number: everything you own, minus everything you owe. If you have a mortgage, some savings, a workplace pension and a credit card balance you’re not thrilled about — you already have a net worth. You just haven’t written it down.
Most people avoid this exercise because they assume the number will be bad, or embarrassing, or depressing. Sometimes it is lower than you’d hope, especially in your 20s and 30s when debt (student loans, a mortgage) outweighs what you’ve built up. That’s normal, not a failure. The point of calculating it isn’t to judge yourself against some imaginary benchmark — it’s to have a baseline so you can actually see whether you’re moving forward or backward.
This article walks through exactly how to calculate it, what counts and what doesn’t, and how to use the number once you have it — because a net worth figure that just sits in a spreadsheet gathering dust isn’t worth the ten minutes it took to calculate.
What net worth actually means
Your net worth is a snapshot, not a performance score. It’s calculated as:
Net worth = Total assets − Total liabilities
- Assets are things you own that have monetary value: cash, savings, investments, pensions, property, even a car (sort of — more on that below).
- Liabilities are debts you owe: mortgage balance, credit cards, personal loans, car finance, student loans.
The result can be positive or negative, and both are informative. A negative net worth in your late 20s with a big student loan balance isn’t a crisis — it’s just where you are. The number only becomes useful when you track it over time and watch the trend.
Step 1: List every asset you have
Go through each category and write down the current value — not what you paid for it, what it’s worth now.
- Cash: current accounts, savings accounts, cash ISAs (an ISA, or Individual Savings Account, is just a tax-free wrapper around savings or investments — you don’t pay tax on interest or growth inside it)
- Investments: stocks and shares ISAs, general investment accounts, premium bonds
- Pensions: your workplace pension and any personal pension or SIPP (self-invested personal pension). Check your latest pension statement or log into the provider’s app for the current value
- Property: the current market value of your home, not what you bought it for. Use a recent estate agent valuation or a reasonable estimate based on similar local sales — tools like Rightmove’s sold prices section help here
- Other valuable assets: a car (use its realistic resale value, not what you paid), any valuable jewellery, or a share in a business you own
Don’t bother listing everyday possessions — furniture, clothes, electronics. They have resale value in theory, but it’s negligible and not worth the admin. Net worth calculations are about meaningful financial assets, not a home inventory.
Step 2: List every liability you owe
This is the less fun part, but it’s just as important to get right.
- Mortgage: your outstanding balance, not the original loan amount. This is on your latest mortgage statement or your lender’s online portal
- Credit cards: the balance you currently owe, not your credit limit
- Personal loans and car finance: outstanding balance owed
- Student loans: your current balance (check via the Student Loans Company if you’re unsure)
- Any other debts: money owed to family, buy-now-pay-later balances, overdrafts you’re carrying
Be honest here. It’s tempting to skip the small stuff — a £400 buy-now-pay-later balance, a lingering overdraft — but these add up and skew the picture if you leave them out.
Step 3: Do the maths
Once you’ve got both lists, it’s simple subtraction.
| Category | Example amount |
|---|---|
| Cash savings | £6,000 |
| Stocks and shares ISA | £4,500 |
| Workplace pension | £18,000 |
| Home value | £280,000 |
| Car (resale value) | £5,000 |
| Total assets | £313,500 |
| Mortgage balance | £210,000 |
| Credit card balance | £2,200 |
| Car finance | £6,000 |
| Total liabilities | £218,200 |
| Net worth | £95,300 |
That’s it. No complicated formula, no spreadsheet wizardry required — just two honest lists and a subtraction.
The misconception: net worth isn’t the same as cash in the bank
A common mix-up is treating net worth as if it’s spendable money sitting somewhere. It isn’t. Most people’s net worth is tied up in illiquid assets — primarily their home and pension — that they can’t easily access or spend tomorrow.
This matters because a healthy-looking net worth can mask a genuine cash-flow problem. Someone with £300,000 of equity in their house and £40,000 in their pension can still struggle to cover an unexpected £800 car repair if they have no accessible savings. Net worth tells you about long-term financial position. It tells you nothing about whether you can cover this month’s bills. Both numbers matter, and they’re not interchangeable.
If your net worth is healthy but your emergency fund — the separate pot of accessible cash for unplanned costs, usually aimed at covering three to six months of essential outgoings — is thin or nonexistent, that’s worth addressing before anything else.
Should you include your pension?
Yes, but with a mental asterisk. Your pension counts as an asset because it genuinely belongs to you and will eventually become spendable income. But it behaves differently from other assets:
- You generally can’t access it until age 55 (rising to 57 from 2028)
- Its value will fluctuate with investment performance, sometimes significantly
- It’s taxed differently when you eventually draw from it
Some people calculate two versions of their net worth — one including pensions, one excluding them — to separate “long-term wealth” from “what I could realistically use in the next few years.” Neither is more correct; they’re just answering different questions.
How often should you calculate it?
Once a quarter is plenty for most people. Monthly tends to create noise rather than insight — property values and pension valuations don’t move meaningfully month to month, and checking too often just amplifies normal market wobbles into something that feels alarming.
| Frequency | Good for | Downside |
|---|---|---|
| Monthly | People actively paying down debt or building savings fast | Can cause stress over normal short-term fluctuations |
| Quarterly | Most people — a sensible rhythm | Requires a bit of discipline to keep up |
| Annually | Minimal effort, big-picture check-in | Too infrequent to catch problems early |
Pick a recurring date — your birthday, the start of the tax year in April, 1 January — and make it a habit rather than something you do once in a burst of motivation and never again.
What a “good” net worth actually looks like
There’s no official benchmark, and anyone giving you a precise target figure for your age is guessing. Your net worth depends heavily on where you live, whether you own property, your income history, and plenty of circumstances outside your control.
What matters far more than the absolute number is the direction. Is it going up over time, even slowly? Are you reducing high-interest debt (credit cards, especially) faster than you’re adding to it? Is a larger share of your assets sitting in things that grow — pensions, investments — rather than depreciating things like car finance?
If you want a general sanity check beyond trend-watching, MoneyHelper (the government-backed guidance service) has free tools and calculators that can help you benchmark pension savings and overall financial health without pushing you toward any specific product.
The bottom line
- Do the calculation today, even roughly. You don’t need perfect figures — estimate your home value and round your account balances if needed. A rough snapshot beats no snapshot.
- Separate liquid and illiquid assets mentally. Your house and pension are real wealth, but they won’t cover an emergency bill. Check your accessible savings separately.
- Track it quarterly, not daily. Pick a fixed date, note the number, and move on. The trend over a year tells you far more than any single reading.
- Prioritise high-interest debt in your liabilities list. A credit card balance sitting at 20%+ interest is doing more damage than almost any asset is doing good — tackling that first usually moves your net worth faster than anything else.
- Check your pension value properly, not just the headline total. Log into your provider directly or use your government gateway to check your separately, since old statements and app estimates can lag behind reality.
