Tracking Net Worth: Why the Number Matters and How to Calculate It
Most people have a rough sense of their income but no idea what they are actually worth. Net worth collapses your entire financial position into a single number — and watching that number change monthly is one of the most effective ways to stay on track with long-term goals.
Assets minus liabilities
Net worth is simple in concept: everything you own minus everything you owe. The challenge is being thorough — many people forget to include pensions, under-value property, or forget small debts.
| Item | Type | Value |
|---|---|---|
| Current account | Asset | £3,200 |
| Easy-access savings | Asset | £12,000 |
| Stocks & Shares ISA | Asset | £28,500 |
| Workplace pension (transfer value) | Asset | £61,000 |
| Property (market value) | Asset | £285,000 |
| Mortgage outstanding | Liability | −£187,000 |
| Car finance balance | Liability | −£4,200 |
| Credit card balance | Liability | −£800 |
| Net worth | £197,700 |
Hypothetical example. Property equity = market value minus mortgage = £98,000. Liquid net worth (excluding property and pension) = £38,700.
What to include and what not to
Include:
- All bank accounts, savings, and cash ISAs
- Investment accounts, stocks & shares ISAs, and GIAs
- Pension pots (workplace and personal — use transfer value or current fund value)
- Property equity (current value minus mortgage balance)
- Vehicles (current market value, not purchase price)
- All debts: mortgages, loans, credit cards, BNPL balances, student loans
Do not include:
- Personal possessions (furniture, electronics) unless genuinely valuable and liquid
- Future income or inheritance expectations
- Expected pension payments not yet accrued
Liquid net worth vs total net worth
It is worth tracking two figures separately. Total net worth includes your home equity and pension — which are real wealth but not things you can spend tomorrow. Liquid net worth covers only assets you could access within a reasonable timeframe: savings, investment accounts, and ISAs.
Someone with £500,000 total net worth but only £20,000 in liquid assets has very different financial flexibility than someone with £200,000 total and £150,000 liquid. Both numbers tell you something important.
Why monthly tracking changes behaviour
The act of measuring your net worth monthly creates a feedback loop. You notice when a spending month dents your savings balance. You see the compounding effect of investments starting to accelerate. You feel the momentum of a paid-off debt dropping off your liabilities list. Financial intentions remain abstract; a monthly net worth number makes progress — or its absence — concrete.
Many people who start tracking find they naturally reduce discretionary spending, prioritise debt payoff, and make more deliberate investment decisions — not because of a rule, but because they now see the score.
Frequently asked questions
What is net worth?
Net worth is the total value of everything you own (assets) minus everything you owe (liabilities). Assets include cash, savings, investments, pension value, and property equity. Liabilities include mortgages, loans, credit card balances, and any other debts. A positive net worth means assets exceed liabilities; a negative net worth means you owe more than you own.
Should I include my pension in my net worth?
Yes, with a caveat. Your pension is a real asset and excluding it dramatically understates your financial position. However, you cannot access it until age 57 (in the UK) and the value can change with markets. Use your current transfer value or projected pot size, and note it separately so you can see both your liquid net worth (accessible assets) and total net worth (including pension).
Should I include my home in my net worth?
Include the equity — the difference between the property's current market value and the outstanding mortgage balance. Your home is an asset, but it is illiquid: you cannot easily spend it without selling or remortgaging. Many people track net worth with and without property equity to get a clearer picture of their investable/liquid position.
What is a good net worth at my age?
There is no universal answer — net worth depends on income, location, family circumstances, and when you started working. A common US benchmark is 1× your annual gross income by 30, 3× by 40, 6× by 50. UK equivalents are roughly similar but vary with salary levels and property ownership. The more useful metric is whether your net worth is growing each month — the trajectory matters more than the absolute number.
