How NZ net worth is calculated

Net worth = total assets − total liabilities. Both flow and stock measure of wealth.

  1. 1

    Sum all assets

    Assets = home + KiwiSaver + investments + cash + vehicles + other

    Use current market value for the home, not purchase price.

  2. 2

    Sum all liabilities

    Liabilities = mortgage + student loan + credit cards + personal/car loans + other debts

    Include any HP, AfterPay balances etc.

  3. 3

    Net worth = assets − liabilities

    Net_worth = total_assets − total_liabilities

    Track quarterly to see trend.

  4. 4

    Compare to NZ median

    vs_median = (your_net_worth − $397,000) ÷ $397,000 × 100%

    Stats NZ HES 2024 median household net worth.

Result: Assets $1,000,000 − Liabilities $480,000 = Net worth $520,000 (+31% vs NZ median).

Frequently Asked Questions

How is net worth calculated in NZ?
Net worth = total assets − total liabilities. Common assets include your home (market value), KiwiSaver balance, term deposits, vehicles (current value), and other investments. Common liabilities include the mortgage balance, student loan, credit card debt, personal loans, and HP. Stats NZ Household Economic Survey (2024) puts the median household net worth at $397,000. Source: Stats NZ HES.
Should I include my home in net worth?
Yes — both your home (at market value) and the mortgage balance. Some advisers separate "net worth" (everything) from "investable assets" (excluding the home you live in) since you can't spend home equity without selling. Both views are useful for tracking progress. Source: MoneyHub.
How does NZ household net worth compare to other countries?
NZ has high household net worth by OECD standards, driven by housing. Per Credit Suisse Global Wealth Report 2024, NZ ranks #6 globally by median wealth at ~US$248,000 (NZ$397,000) — behind Australia (#1 at US$496k), Belgium, Luxembourg, Hong Kong, and the UK. But about 60% of NZ household wealth is locked in the family home. Stripping out home equity, NZ ranks ~20th — well below Australia and the UK. This 'asset-rich, income-poor' profile is why so many Kiwis feel financially stretched despite high net worth. Source: Stats NZ HES + Credit Suisse 2024 + RNZ analysis.
How often should I recalculate my net worth?
Quarterly is the sweet spot for most people. Annual is the minimum (do it at tax-year end, 31 March). Track it monthly only if you're actively managing investments or paying down debt aggressively — daily tracking causes anxiety, not better decisions. Major life events that warrant immediate recalculation: buying or selling a home, redundancy, inheritance, divorce, starting a business, having a child, or any large purchase or debt change. Use the same valuation method each time (e.g. Homes.co.nz CV for the house, last KiwiSaver balance, current TD account balances). Consistency matters more than precision. Source: Sorted NZ.
