The Formula Is Trivial. The Inputs Are the Whole Problem.

Net worth = Everything you own − Everything you owe

Nobody gets that subtraction wrong. What makes one person's net worth figure useful and another's meaningless is the decisions made before the subtraction: which items to include, what value to put on them, and which debts get quietly left off the list.

The whole of this page is about those decisions, because they are what the calculation actually consists of.

What Value Do You Put on Things You Own?

The rule that keeps the figure honest is to value everything at what you could realistically sell it for today, not what you paid and not what you feel it is worth.

The last row is where people most often flatter themselves. A house full of belongings might fetch very little in a hurried sale, and counting it at replacement cost produces a number that cannot survive contact with reality. Leave ordinary possessions out entirely and include only items you would genuinely list and sell — a second vehicle, valuable equipment, a collection with an established market.

The Debts People Forget

Assets get counted enthusiastically and liabilities get counted selectively. A complete list includes several things that do not feel like debt.

• The full mortgage balance, not the monthly payment. The payment is a cash flow; the balance is the liability.
• Tax owed but not yet paid. Self-employed people holding a reserve for a future bill are holding someone else's money in their own account. It is an asset and a liability simultaneously, and netting to zero is the correct treatment.
• Credit card balances in full, including amounts you intend to clear this month. Money already spent is owed regardless of when the statement arrives.
• Student loans, on whatever terms they carry. Where repayment is income-contingent and the balance may eventually be written off, some people exclude it — that is defensible, but the treatment should be recorded and kept consistent between periods.
• Buy-now-pay-later and instalment plans. Small individually and frequently invisible in aggregate.
• Money owed to family. Informal, undocumented, and still owed.

The Four Items People Argue About

Most disagreements about net worth come down to the same handful of items. There is a defensible answer to each.

Your home. Count it, at a realistic sale value, with the mortgage as a liability against it. The objection — that you have to live somewhere, so you cannot spend it — is fair, and it is an argument for also tracking net worth excluding the home rather than for pretending the asset does not exist.

Your pension. Count it. It is money you own, and leaving it out makes long-term saving invisible in the one measure designed to capture it. That it is inaccessible for years is a liquidity question, not an ownership one.

Your car. Count it, and re-value it honestly each time. A vehicle carried at purchase price is the most common single source of an inflated net worth figure, since it declines every month while the spreadsheet does not.

Volatile holdings. Count them at today's market value, accepting that this makes the total move with the market. Choosing a favourable historic price instead means the figure is no longer measuring anything.

Liquid Net Worth Is the More Revealing Number

The headline figure counts everything you own. Liquid net worth counts only what could become cash quickly without a forced sale.

Liquid net worth = Cash, savings and readily sellable investments − Short-term debts

Someone with 400,000 of net worth held almost entirely in a house and a pension may have very little liquid net worth. That is not a problem in itself, but it describes a specific vulnerability: a job loss or a large unexpected cost has to be met from a small pool, and the only alternatives are borrowing or selling something slowly.

Tracking both numbers tells you two different things. The total says whether you are building wealth. The liquid figure says whether you could absorb a shock without dismantling what you have built.

What the Number Is Actually For

A single net worth figure in isolation says almost nothing. Compared against your own previous figures it becomes the clearest measure of financial progress available, because it is the only one that captures saving, investing, and debt repayment in a single number.

Income does not do this — a high earner spending everything shows no progress at all. Savings alone do not either, since money moved into a savings account while a credit card balance grows is not progress. Paying down debt increases net worth exactly as much as saving the same amount, which is why it belongs in the same measure.

One caveat about frequency. Calculating monthly mostly records market movement and rounds in valuation guesses, which is noise rather than information. Quarterly or twice a year is often enough to show the trend, and once a year is enough if your position is stable. Whatever interval you pick, keep the valuation method the same each time — changing how you value the house between periods produces a change in net worth that reflects nothing you did.

Couples and Joint Finances

For a household, the practical approach is to keep three columns: each person's individual position and the joint one. Joint assets and joint debts sit in the middle column, and the household total is the sum.

Keeping individual figures visible rather than merging everything is worth the small extra effort. It shows who is carrying which debts, makes an imbalance in pension savings obvious while there is still time to address it, and means neither person loses sight of their own position. Merging into one number is simpler and hides all three things.
