How to Calculate Your Net Worth (And Why It Matters)

The formula

That's the whole calculation. The complexity is in making sure you're including the right things on each side of the equation.

What counts as an asset

Assets are things you own that have monetary value. A thorough list includes:

• Cash and savings: Everyday accounts, savings accounts, term deposits, cash on hand
• Investments: Shares, ETFs, managed funds, bonds, cryptocurrency
• Retirement savings: Superannuation (Australia/NZ), 401(k) or IRA (US), pension funds — include the current balance, not the projected future value
• Property: The current market value of any property you own, including your home
• Vehicles: Cars, motorcycles, boats — use current resale value, not what you paid
• Business interests: Your share of any business you own, valued conservatively
• Other valuables: Jewellery, collectibles, art — only include if you'd realistically sell them and know their value

Use current market values, not purchase prices. A car you bought for $30,000 five years ago may be worth $18,000 today. Your house may be worth significantly more than you paid. Use realistic current figures.

What counts as a liability

Liabilities are everything you owe. This includes:

• Mortgage: The current outstanding balance on any property loans
• Car loans: Outstanding balance, not the original loan amount
• Personal loans and buy-now-pay-later: Any outstanding balances
• Credit card debt: The current balance you're carrying, not the credit limit
• Student loans: Outstanding education debt
• Other debts: Tax debts, money owed to family, any other financial obligation

A worked example

Here's a straightforward example for someone at the early-to-mid stage of their financial life:

Assets: Savings account $12,000 / Share portfolio $8,500 / Superannuation $45,000 / Car $14,000. Total assets: $79,500

Liabilities: Car loan $9,000 / Credit card balance $2,200 / Personal loan $5,800. Total liabilities: $17,000

Net worth: $62,500

A positive net worth at this stage, trending upward as savings accumulate and debt is paid down. That's the story the number tells.

What if your net worth is negative?

A negative net worth — where total liabilities exceed total assets — is common, particularly for younger people or those early in their careers. Student debt, car loans and credit card balances can easily outweigh accumulated savings in the first decade of working life.

A negative net worth isn't a verdict on your finances — it's a data point. What matters is the direction of travel. If it's increasing from, say, -$40,000 to -$28,000 to -$15,000 over three years, that's meaningful progress even if the number is still negative.

If your net worth is negative and not improving, it's a signal that debt is growing faster than assets. That usually points to either a spending problem, a structural income issue, or high-interest debt that needs to be addressed before savings can accumulate meaningfully.

Common mistakes in calculating net worth

Overvaluing property. Using the purchase price rather than current market value is one of the most common errors. Property may be worth more or less than you paid, and in many markets the gap is significant. An independent estimate or recent comparable sales data gives you a more accurate figure.

Forgetting superannuation. Many people leave retirement savings out of their net worth calculation because it feels untouchable. It isn't — it's an asset, even if it's illiquid until retirement. Include the current balance.

Using credit limits instead of balances. Your $10,000 credit card limit isn't a liability — your $3,200 balance is. Only include what you actually owe.

Including the value of items you'd never actually sell. If you have antique furniture or jewellery that's been in the family for decades and you have no intention of selling it, including it as an asset creates a misleadingly optimistic picture. Be conservative on illiquid personal items.

Why the trend matters more than the number

Your net worth at any single point in time tells you relatively little on its own. A 28-year-old with a net worth of $25,000 and a 55-year-old with a net worth of $25,000 are in very different positions. The absolute number is context-dependent.

What the number is most useful for is tracking. Calculate it once, then do it again in six or twelve months. Is it higher? By how much? Is it growing faster than you expected, or slower? The trend tells you whether your financial decisions are moving you in the right direction.

Most people who track their net worth consistently report that the act of tracking creates its own motivation. When you can see the number moving, the trade-off between spending now versus saving becomes tangible in a way that a monthly budget review rarely is.

What to do with your net worth figure

Use it as a baseline for setting medium-to-long-term financial goals. If your target is financial independence at 60, what net worth do you need to reach? What's the gap between where you are now and where you need to be? What savings rate is required to close that gap at a realistic investment return assumption?

These questions are impossible to answer without knowing your starting point. Net worth gives you that starting point. Calculate it today, review it annually and let the trend inform your decisions.
