Your net worth number isn't what you think it is

Ask most people what their net worth is and you'll get one of two answers: a shrug, or a number that's actually just their bank balance. Both miss the point of the number, which is to answer a much more useful question than "how much cash do I have right now": if I stopped everything today, sold what's sellable, and paid off what's owed, what would actually be left?

The two mistakes that break the number

The first mistake is counting only what's easy to see — checking and savings accounts — and ignoring the assets that don't show up in a banking app: the value tied up in things you own outright, money owed to you, anything with real resale value. The second, more dangerous mistake is the opposite: counting assets but forgetting the debts sitting against them, which turns a real net worth calculation into a vanity number that quietly overstates how well things are actually going.

A number that only ever goes up because you stopped subtracting debt isn't tracking your finances — it's decorating them.

Why this number, specifically, is worth tracking monthly

Income and spending are noisy month to month — one big bill, one bonus, one irregular expense, and the trend line means nothing. Net worth is quieter and more honest, because it nets all of that out automatically. A single upward trend line, checked once a month, tells you more about whether your financial decisions are working than a dozen category-by-category spending reports.

The habit worth building isn't checking your balance more often. It's checking one number, once a month, that already accounts for everything you own and everything you owe — and watching whether that one line is moving in the direction you want.
