Net Worth: The Single Best Measure of Financial Health
Income tells you what you earn. Net worth tells you what you have built. It is the truest single snapshot of your financial position.
People often judge financial success by income — how much someone earns. But a high earner with high debts can be in a weaker position than a modest earner who has built steadily. The number that captures this is net worth. This guide explains what it is, how to calculate it, and how to read it well.
What Net Worth Is
Net worth is simply what you own minus what you owe. It is the value left over if you converted everything you have into cash and paid off every debt.
It is a snapshot — a measure of your position at one moment in time — rather than a flow like income. And it is the single best one-number summary of financial health, because it accounts for both sides of the ledger.
Assets: What You Own
Assets are things of value you hold. They typically include:
- Cash — bank accounts and savings.
- Investments — shares, funds, and similar holdings.
- Retirement savings — superannuation or pension balances.
- Property — the market value of a home or other real estate.
- Other valuables — a vehicle or other significant possessions, at realistic resale value.
Liabilities: What You Owe
Liabilities are your debts. They commonly include a mortgage, car loans, personal loans, credit card balances, and any other money owed. The total of these is subtracted from your assets.
A Worked Example
Suppose someone has these figures:
| Assets | Value |
|---|---|
| Cash and savings | 20,000 |
| Investments and super | 120,000 |
| Home (market value) | 600,000 |
| Total assets | 740,000 |
| Liabilities | Value |
|---|---|
| Mortgage | 380,000 |
| Car loan | 15,000 |
| Total liabilities | 395,000 |
Net worth = 740,000 − 395,000 = 345,000. That single figure says more about their financial health than their salary alone ever could.
Calculate and track your net worth.

A single net worth figure is useful, but the direction it moves over time is far more revealing. Net worth that climbs year after year shows you are building — saving, paying down debt, growing investments. A figure that stalls or falls is an early signal worth paying attention to.
This is why many people calculate their net worth on a regular schedule, perhaps once or twice a year. Comparing the snapshots tells the real story of progress.
Negative Net Worth Is Not Failure
It is entirely possible — and common — to have a negative net worth, where debts exceed assets. A recent graduate with study debt, or someone early in a mortgage, may be in exactly this position.
Negative net worth is not a verdict on your character or future. For many people it is simply a stage. What matters is the trend: a negative net worth that is steadily climbing toward zero and beyond is a sign of real progress, even while the number is still below zero.
Frequently Asked Questions
Is net worth better than income as a measure?
They measure different things. Income is a flow; net worth is a position. Net worth is the better single snapshot of overall financial health because it includes debt.
How often should I calculate it?
Once or twice a year is enough for most people. The value is in comparing snapshots over time, not in frequent updates.
Should I include my home?
Yes — at a realistic market value — and include the mortgage as a liability. Just be consistent each time you measure.
Net worth — assets minus liabilities — is the clearest single measure of where you stand financially. Calculate it honestly, watch the trend rather than fixating on the figure, and remember that even a negative number heading the right way is a sign you are building. It is the scoreboard worth checking.
