The definition that nobody disagrees with
Net worth = (cash + investments + pensions + property + crypto + any other assets) minus (mortgage + loans + credit-card balances + any other liabilities). It is the standard financial definition and has been for a century. Nothing exotic.
What is exotic is how rarely most people actually compute it. Surveys consistently find that fewer than 30% of UK adults could state their own net worth within +/-20%. The number for EU averages is similar. The gap is not a knowledge problem - the formula is two lines - it is a tooling problem. Most consumer banking apps do not even try to show you this number.
What the bank-statement view misses
Five categories at least.
- Investments. ISAs, SIPPs, GIAs, PEAs, assurance-vie, Depots, PIRs - none of these show in your bank app. For most adults over 35 they are 30-70% of net worth.
- Pensions. Workplace pensions in the UK and equivalent across the EU are typically the single largest asset for adults in their 40s and 50s. They almost never appear in any consumer-money app.
- Property. Home equity is the largest single asset for most homeowners. It does not appear in any banking app.
- Crypto. If you hold any, it is on an exchange or a wallet, not in a bank.
- Liabilities. Mortgages and student loans are not in your banking app's balance, except as monthly outflows. They are part of your net worth.
The cost of not seeing it
Three concrete consequences. First, savings goals get set against the wrong base. People aim for an emergency fund of '6 months of salary' against their current-account balance, ignoring that their actual liquid wealth is two or three times higher because of investments and savings. Second, decisions about whether to overpay a mortgage, or to move money from cash into investments, get made without a denominator. Third, retirement planning runs on the wrong number entirely - 'I have GBP 30,000 saved' versus 'I have GBP 30,000 in cash, GBP 240,000 in pensions, GBP 110,000 in equity, no mortgage, net worth of GBP 380,000'. Those two people have very different problems.
What an honest picture looks like
An honest net-worth picture in 2026 has four properties. It includes assets and liabilities. It is in one base currency, regardless of where the underlying sits. It updates without you having to type anything in. And it is broken down by category (cash, investments, pensions, crypto, property) so you can see the shape of your wealth, not just the total.
PSD2 open banking, MiCA crypto exchange visibility and consumer-facing pension dashboards (Pensions Dashboard in the UK; equivalent initiatives across EU member states) have together made this possible without spreadsheets for the first time in retail finance. The tools that surface it are still uneven, but the data layer is finally there.
Where Bank AI sits
We are direct about this. Bank AI's purpose is to give you the honest picture - cash, investments, pensions and crypto in one daily-refreshed net-worth view, in your home currency, with the wrappers (ISA, SIPP, PEA, assurance-vie, Depot) treated as first-class metadata. Property is in product roadmap; pensions coverage in product. We are not the only app that can do this, but we believe we are the AI-native one for the UK and EU - and that an AI you can ask questions to is the next layer above the dashboard, not a gimmick on top of it.
If you have read this far and still do not know your net worth within +/-20%, that is the gap worth closing. The mechanics are not the hard part anymore.
