Net Worth vs Income: Why They're Not the Same

Income is what flows in each month. Net worth is what has actually stuck around.

They're related, but they measure completely different things; and plenty of high earners are worth less than people on half their salary.

What each one tells you

Income is a speed. It tells you how fast money is arriving: $85,000 a year, $3,270 a fortnight.

Net worth is a level. It tells you where all that money has landed: what you own minus what you owe, right now.

Think of a bathtub. Income is how hard the tap is running. Net worth is how much water is in the tub. A roaring tap means nothing if the drain is open just as wide.

Can you have a high income and a low net worth?

Easily. Someone on $180,000 with a leased car, a maxed credit card and no savings can have a lower net worth than a nurse who has salary-sacrificed into super and paid down their HECS for a decade.

It works the other way too. A modest income with consistent saving builds real net worth. It's slower, but the direction is what compounds.

This is why lifestyle creep is invisible on a payslip. Your income says you're doing better every year. Only your net worth can tell you whether that's actually true.

Which one should you track?

Track your net worth. Your income barely needs tracking — you already know what you earn, and your bank records every transaction.

What your bank can't show you is your position: whether everything you've earned is accumulating into something or washing straight through. That's a number you have to calculate yourself, and checking it monthly is enough to see the trend.

A payslip tells you what you earn. A net worth statement tells you what you've kept.

Perch tracks the number your bank doesn't: your position, month by month, so you can see whether your income is actually turning into wealth.
