How to Track Your Net Worth and Why It Matters

What Is Net Worth?

Net worth is the single most comprehensive measure of your financial position. It's calculated by subtracting everything you owe (liabilities) from everything you own (assets). A positive net worth means you own more than you owe; a negative net worth means you owe more than you own.

Net worth is more meaningful than income alone. A person earning £100,000 per year with significant debts and no savings may have a lower net worth than someone earning £40,000 who has been saving consistently for a decade. Net worth tracks progress, exposes financial weaknesses, and provides a clear picture of where you actually stand — not just how much flows through your bank account.

Assets: What to Include

Assets are anything you own that has financial value:

• Property: The current market value of any property you own (not the mortgage balance — that's a liability)
• Cash and savings: All current accounts, savings accounts, Cash ISAs, Premium Bonds
• Investments: Stocks and shares ISAs, general investment accounts, individual shares
• Pension: Your current estimated pension pot value (for defined contribution schemes; defined benefit schemes require a different calculation — see below)
• Vehicles: Current market value (check on AutoTrader for cars)
• Business interests: Estimated value of any business ownership
• Other valuable possessions: High-value jewellery, art, collectibles — though these are illiquid and tricky to value

Liabilities: What to Include

Liabilities are everything you owe:

• Mortgage outstanding balance
• Personal loans
• Credit card balances
• Car finance outstanding
• Student loans (note: many financial advisers suggest leaving these out for net worth calculations, as they function more like a graduate tax than a traditional debt — see below)
• Overdrafts
• Any other debts

A Note on Pension Valuation

Defined contribution (DC) pension values are straightforward — log into your pension provider and check your pot value. Include 100% of the pot value in your assets, though remember you can't access it until 57 (rising to 58).

Defined benefit (DB) pensions are harder. A common approach is to multiply your projected annual pension income (at current accrual) by 20–25. So if your DB pension would pay £10,000 per year based on current service, the asset value is approximately £200,000–£250,000. This is a rough estimate — a financial adviser can provide a more precise "transfer value" if needed.

Student Loan: Include or Exclude?

UK Plan 2 (post-2012) student loans are unusual: they're written off after 30 years, repayments stop if income drops below the threshold, and most lower-to-middle earners will never fully repay them. For this reason, many UK personal finance commentators recommend treating student loans as excluded from net worth calculations — they function as an income-contingent tax rather than a traditional liability. Whether to include them is a matter of personal preference; be consistent in your approach.

Calculating Your Net Worth: A Simple Example

Assets:

• Property value: £280,000
• Savings and ISA: £12,000
• Pension pot: £45,000
• Car value: £8,000
• Total assets: £345,000

Liabilities:

• Mortgage outstanding: £210,000
• Car finance: £4,000
• Credit card balance: £2,000
• Total liabilities: £216,000

Net worth: £345,000 − £216,000 = £129,000

Why Tracking Net Worth Monthly Matters

Tracking net worth monthly provides insights that no other financial metric can:

• It shows whether you're actually building wealth or just staying in place
• It reveals the impact of paying down debt vs building savings
• It provides a clear picture of whether your mortgage overpayments are ahead of property value changes
• It maintains awareness of your total financial picture, including pension growth
• It provides early warning if liabilities are growing faster than assets

Tools for Tracking Net Worth

• A simple spreadsheet: The most flexible option. Create columns for each asset and liability, update monthly, and chart the trend
• Moneyhub: UK-based open banking app that connects to bank accounts, investments, pensions, and mortgages, tracking net worth automatically
• Emma: Similar to Moneyhub, with net worth tracking across linked accounts
• Manual calculation with a dedicated notes app: Even a monthly note in your phone with the key figures provides valuable trend data over time

Setting Net Worth Targets

Some financial planners suggest a target net worth (excluding property) of 1× your annual salary by age 35, 3× by 45, and 7–10× by retirement. These are rough guides rather than prescriptions — your target depends on your lifestyle, goals, and whether you have a defined benefit pension (which dramatically changes the picture).

The more useful target is directional: is your net worth growing each month? Even modest monthly growth, compounded over decades, transforms your financial position.

Conclusion

Tracking net worth takes 30 minutes to set up and about 10 minutes per month to maintain. Yet the insight it provides — a comprehensive, single-number summary of your entire financial position and its trajectory — is more valuable than any individual account balance or income figure. Start today: list your assets, list your liabilities, subtract one from the other, and record the result. Then do it again next month. The trend line, over years, tells the real story of your financial life.
