What Is Net Worth? Definition and Example | Cash Book

Ask ten people what their net worth is and you get ten different rules. Some count the car; some leave it out because they drive it every day and cannot picture selling it; some count a pension they will not touch for thirty years, while others treat that as imaginary money belonging to a version of themselves they have not met yet. Almost nobody counts the rental deposit, which is real, is theirs, and is sitting with a landlord who will find a reason to keep half of it. The textbook is clean. Everything you own minus everything you owe, at one moment. Households pick a working definition and quietly stick to it, which is fine, because the figure matters far less than the direction it is moving in. A net worth of $15,300 tells you almost nothing. The same $15,300, six months after it was $11,800, tells you nearly everything.

What counts, and at what price

Three steps. List your assets at a realistic current value. List your liabilities in full. Subtract.

Step one is where people flatter themselves: a car that cost $18,000 and would sell for $9,000 is a $9,000 asset and not an $18,000 one, and furniture and electronics are usually left out altogether, because their resale value is both small and uncertain and pricing a second-hand sofa is an evening you will never get back. Step two is the opposite flattery, skipping a card balance you fully intend to clear at the end of the month. It is $1,200 owed until it is paid. Treat the whole exercise as a measurement rather than a score and it stops being tempting to round.

Six months is the unit

Checking holds $2,300, savings $9,700 and an investment account $2,000, so financial assets come to $14,000; the car would sell for about $9,000, which puts total assets at $23,000; against that sit a $6,500 car loan and $1,200 on a credit card, $7,700 owed in all. Net worth is $15,300.

Now leave it alone and come back in six months. Savings are $11,500. The loan is down to $5,400. The card is clear. The car has slipped to $8,400. Assets $24,200, liabilities $5,400, net worth $18,800. Up $3,500.

That $3,500 is six months of positive cash flow less the $600 the car lost by sitting outside, and neither half of it would have surfaced in a single snapshot, which is the entire reason anyone runs the calculation twice rather than once. It is also why monthly or quarterly is the right rhythm. Check it daily and you are measuring the market, not your habits.

The part your log already knows

The liquid part, the accounts, is what an expense tracker keeps current without being asked. In Cash Book you set up an account for each place your money sits, cash, cards, savings, each carrying its own balance, and the Accounts screen puts a single net-worth number over the account cards, so every expense you log reduces an account, every income entry raises one, and a transfer moves money between two of them while leaving the total exactly where it was. That is the whole mechanism.

So the monthly check is a glance rather than a session. Savings up $300, card account down $180, the number moved $480, and Insights tells you which tags did it. A mortgage or a pension still has to be typed in by hand for the full figure. But the part that changes week to week is already done.

Cash is the weak point and always has been. Withdraw $200, spend it over five days, log none of it, and the cash account reads fuller than your wallet; that drift is the whole subject of the cash spending guide, and the more entries that arrive on their own, by voice, by receipt snap, by Apple Pay auto-logging, the smaller the gap between the app's balances and the bank's.

Net worth is the level. Cash flow is what raises or lowers it, discretionary spending is the part of that flow you control most directly, and the rest of the terms sit in the glossary.

A number you improve by rounding is not a measurement.
