How to Track Your Net Worth (and Why It Matters for FIRE)

Your net worth is the single most important number in personal finance. It is the total value of everything you own, minus everything you owe. Income tells you how much flows in. Savings rate tells you how much you keep. But net worth tells you where you actually stand.

If you are serious about financial independence -- or just want to know whether you are making progress -- tracking net worth is where you start.

Key takeaways

• Net worth = total assets minus total liabilities. It is the only number that captures your full financial position.
• Include superannuation. It is your money, even if you cannot access it yet.
• Track monthly. Weekly is noise. Quarterly is too slow to catch problems.
• Spreadsheets work but go stale. Most Australian finance apps only cover part of the picture.
• Your net worth trend matters more than any single snapshot.

Why track net worth, not just income or savings

Income is a vanity metric. Plenty of people earn $200,000 and have a net worth of $30,000 because they spend everything and carry debt. Savings rate is better, but it only shows one side of the equation -- it does not account for investment returns, property appreciation, or debt being paid down.

Net worth forces you to confront the full picture.

It reveals whether you are actually making progress

You might feel like you are saving well, but if your investments dropped 8% and your HELP debt is growing with indexation, your net worth could be flat or declining. Without tracking it, you would never know.

Monthly snapshots create an honest record. Over six months, you can see exactly how much of your progress comes from savings versus market returns versus debt paydown.

It is the foundation of FIRE planning

Financial independence means your investment portfolio can sustain your lifestyle without employment income. The standard benchmark is 25 times your annual expenses (the 4% rule). If you spend $60,000 a year, your FIRE number is $1,500,000.

You cannot track progress toward that number without knowing your net worth. And you cannot build a realistic FIRE timeline without monthly data showing your growth rate.

What to include in your net worth

The rule is simple: if you own it and it has a market value, it is an asset. If you owe it, it is a liability.

Assets

Cash and savings accounts

Every bank account, offset account, and term deposit. This is usually the easiest category because the number is exact.

Investments (ETFs, shares, managed funds)

Use current market prices, not what you paid. If you hold 500 units of VAS and it is trading at $96.50, that position is worth $48,250 today. Do not use your cost base -- net worth is about what things are worth now, not what you paid.

Crypto

Bitcoin, Ethereum, whatever you hold. Use the current market price in AUD. Crypto is volatile, which is exactly why you need to include it -- ignoring it gives you a false picture of your exposure.

Superannuation

Yes, include it. Your super balance is your money. You cannot access it until preservation age (currently 60), but it is a real asset growing on your behalf. For someone aged 30 with $95,000 in super, that balance will compound for another 30 years. Excluding it dramatically understates your actual wealth.

Property

Use estimated current market value, not what you paid. Be conservative -- overvaluing your property is the most common way people inflate their net worth. Your property equity is the estimated value minus your outstanding mortgage.

Other assets

Cars, jewellery, art, collectibles. Most people skip these, and that is fine. Unless you own something worth more than $10,000 that you could realistically sell, it adds complexity without adding accuracy.

Liabilities

Mortgage -- your outstanding loan balance.

HELP/HECS debt -- your current balance, indexed annually. HELP debt does not accrue interest, but it is indexed to CPI, so it grows.

Credit card debt -- the full outstanding balance, not the minimum payment.

Personal loans, car loans, afterpay/BNPL -- everything you owe.

How often to track

Monthly is the sweet spot. It is frequent enough to catch trends and infrequent enough that market noise does not dominate. Pick the same day each month.

Weekly tracking is obsessive. Share prices and property values do not move meaningfully in a week. Quarterly is too slow. Three months of drift can set you back significantly before you notice.

Methods for tracking net worth

1. Spreadsheet

The traditional approach. Create a Google Sheet with columns for each asset class and update the values monthly.

Pros: Fully customisable, free, you understand every number because you entered it.

Cons: Manual data entry every month, share prices go stale the moment you type them, easy to skip months when life gets busy, formulas break over time.

A spreadsheet is a great starting point. But after a year, most people either abandon it or wish they had automated it.

2. Finance apps (partial solutions)

Sharesight is excellent for portfolio tracking but only covers listed investments. No cash, no super, no property, no liabilities.

Pocketsmith tracks bank accounts and budgets but does not pull live share prices or handle Australian tax calculations.

The problem for Australians is that no mainstream app covers all asset classes in one place.

3. Grove

Grove tracks every asset class in a single dashboard: cash, ETFs, shares, crypto, super, property, liabilities, and RSU equity. Share and ETF prices update live from market data. It also handles CGT calculations with the 50% discount, FIRE projections using your actual numbers, and daily snapshots so you can see your trend over time.

Worked example: Calculating net worth

Here is what a realistic net worth looks like for a 32-year-old Australian professional.

Assets

Liabilities

Net worth

$950,000 - $432,000 = $518,000

That is the number that matters. Not the $650,000 property value (most of which belongs to the bank). Not the $180,000 in ETFs (which ignores the debt). The full picture.

What your net worth trend tells you

A single snapshot is useful. A trend is powerful.

Monthly data reveals patterns that individual numbers cannot:

• Your effective savings rate. Not what you think you save -- what actually stuck.
• Market impact. How much of your growth came from investment returns versus new contributions.
• Debt paydown velocity. Whether extra mortgage repayments are making a dent.
• Seasonal patterns. Tax refund bumps, bonus months, holiday spending dips.

After 12 months of tracking, you will have a clear picture of your annual growth rate. That number feeds directly into FIRE calculations.

Common mistakes

Not including super. This is the most common error for Australians. Super is your money. Excluding it understates your wealth by tens or hundreds of thousands of dollars.

Not subtracting debt. Listing $650,000 of property as an asset without subtracting the $420,000 mortgage is fantasy accounting. Net worth means net.

Checking too often and panicking over market dips. A 2% dip on $180,000 in ETFs is a $3,600 drop in a single day. Over a month, it will probably recover. Track monthly, not daily.

Overvaluing property. Use conservative estimates based on recent comparable sales.

Comparing to others. Someone with a higher net worth might have inherited property or carry hidden debt. Your trend line is the only comparison that matters.
