The average household budget breakdown
Housing — rent or mortgage repayments — is by far the biggest line in most NZ household budgets, commonly somewhere between 30-40% of take-home pay, and often more in Auckland or Wellington. Food, transport, utilities and insurance round out most of what's left.
After the big three (housing, food, transport), the remainder typically splits across utilities, insurance, healthcare, and discretionary spending like entertainment and eating out — the category that usually has the most room to flex.
| Category | Typical % of spend |
|---|---|
| Housing | 30-40% |
| Food & groceries | 15-20% |
| Transport | 10-15% |
| Utilities | 4-8% |
| Insurance | 3-6% |
| Discretionary / entertainment | 10-15% |
Percentages are illustrative averages and will vary a lot by household size, region and life stage — use them as a rough benchmark, not a target.
"A budget isn't about restriction — it's about visibility. Most overspending happens in categories nobody's actually looking at."
Where most households overspend without realising
Subscriptions, food delivery, and small discretionary purchases are the classic culprits — individually tiny, collectively significant, and easy to lose track of because they don't show up as one big bill.
How your spending compares
Smaller households often see a higher percentage go to fixed costs like housing and utilities, since there are fewer people to spread them across. Build your own full picture in the monthly budget calculator.

Often cited guidance is to keep housing costs under about 30% of take-home pay, though in many NZ centres — especially Auckland and Wellington — actual households often spend more than that.
Housing, usually by a significant margin, followed by food and transport.
