Net Worth Tracker

What is net worth?

Net worth is everything you own minus everything you owe. Add up the market value of your cash, ISAs, SIPP, workplace pension, home equity and other investments, then subtract your mortgage, credit cards and any other debt. The result is a single number that tells you where you actually stand. Your salary and your current account balance both lie. Net worth does not.

We think it is the single most useful number in personal finance to track on a regular schedule. Income shows what you earn. Spending shows what you consume. Only net worth shows whether the gap between those two is actually compounding into freedom or disappearing into the next lifestyle upgrade.

What to include as an asset

Include anything with a clear, defensible market value that you could realistically turn into cash. A useful UK list looks like this:

• Cash in current accounts, savings accounts and Premium Bonds
• Stocks and Shares ISA and Cash ISA balances
• SIPP and workplace pension values (use the figure from your provider's portal)
• General Investment Account holdings outside tax wrappers
• Home equity, using a conservative valuation (more on this below)
• Other investments such as crypto, P2P or business equity you could actually sell

Leave out cars, household contents and personal property unless an item is materially valuable and you would genuinely sell it if you needed cash. Cars depreciate so fast that including them at sticker value flatters the picture and hides what is really happening to your invested wealth.

On the liability side, count your mortgage balance (not the original loan), credit card debt, car finance and personal loans. Student loans are the one judgement call. Some people include them in full because they are a real liability with a real repayment. Others exclude them because UK student loans behave more like a graduate tax: they are written off after a set period and the monthly payment is fixed by income, not balance. We think tracking both views in parallel is the honest answer - include them, but also glance at your net worth with student debt stripped out, because that figure is what your salary actually has to deal with month to month.

Why monthly beats weekly

Track your net worth once a month, on a fixed day. Weekly is too noisy, daily is actively counterproductive, and quarterly is too sparse to spot problems before they compound. A monthly snapshot smooths out short-term market noise and pay-cycle quirks, while still giving you enough data points to see a trend within a year.

The point of the trend line is to teach you to ignore individual months. A 5% market drop feels enormous in the moment and irrelevant once you zoom out. Daily updates train your brain to react to noise. Monthly updates train it to read the signal. Use our compound interest calculator to project where the line should be heading, then watch your actual data either confirm or contradict the plan.

Worked example: five years of a UK household

Consider a couple in their mid-thirties who start tracking in January. They own a home worth £320,000 with a £240,000 mortgage, hold £18,000 across two Cash ISAs, £35,000 across two Stocks and Shares ISAs, £62,000 in workplace pensions, and £4,000 in cash savings. Credit cards and car finance add up to £7,000. Their starting net worth is £192,000, of which £80,000 is home equity and £112,000 is genuinely invested wealth.

• Year 1: clear the credit cards, finish the car loan, ISA contributions of £12,000. Net worth: £218,000.
• Year 2: pension auto-enrolment compounds, ISAs grow 6% real, mortgage drops by £6,000. Net worth: £252,000.
• Year 3: a market wobble takes ISAs and pensions down 8% mid-year but they recover by December. Net worth: £279,000.
• Year 4: house price rises £15,000 on paper, invested assets compound, mortgage drops. Net worth: £321,000.
• Year 5: steady contributions and a 7% real return on equities. Net worth: £368,000.

On paper, their wealth nearly doubled in five years. But strip out home equity and the story changes. Invested net worth went from £112,000 to roughly £260,000. That is the figure that actually pays the bills in retirement.

The number to actually watch: investing net worth

The headline UK net worth statistics are dominated by housing. The ONS Wealth and Assets Survey consistently shows property wealth as the single largest component of median household net worth. That figure looks healthy until you remember that your home cannot pay your gas bill. You cannot eat your kitchen extension.

The number we think is far more useful is your investing net worth - everything you own that could realistically generate income or be spent, excluding the home you live in. ISAs, SIPPs, workplace pensions, GIAs, cash, premium bonds. That is the pot that funds your eventual financial independence. Home equity is real wealth, but it is locked behind the cost and inconvenience of moving, downsizing or releasing equity at a punitive rate. We track total net worth as the headline and investing net worth as the metric that actually changes how we feel about the next ten years.

This is also why we are sceptical of the standard advice to over-pay the mortgage before maxing out invested assets. A pound inside a SIPP or ISA is a pound that can buy you out of work. A pound inside your home is a pound that buys you a slightly smaller mortgage payment. Both matter. They are not equivalent.
