The postcode matters through the costs you actually pay
A useful city comparison starts with the household and property, not a percentage added to a national retirement target. Compare the same home type, household size and lifestyle in each location. An apartment close to public transport and a detached house requiring two cars are different choices even if both are in Melbourne.
Do not compare the level of one city’s Consumer Price Index with another to decide which is more expensive. The ABS explains that price indexes measure changes over time, not price levels between places. A larger index number is not evidence that the whole retirement budget should be increased by that percentage.
Sydney and Melbourne: compare the dwelling and transport together
For Sydney, obtain costs for the suburb and dwelling you expect to use, including strata where applicable, property insurance and the trips to family or an airport. Test whether accessible public transport changes the number of cars your household would need. Use actual quotes rather than assuming every suburb has the same costs.
For Melbourne, include the home’s winter energy needs, maintenance and the relationship between location and transport. A lower rent farther from daily activities can shift spending to fuel, parking or a second vehicle. If you are downsizing, compare the net proceeds and ongoing body-corporate costs of the replacement property.
Brisbane, Perth and Adelaide: price the complete household plan
For Brisbane, check cooling, property-specific insurance, maintenance and transport. Where flood or storm exposure is relevant, obtain a quote for the exact property before treating the housing budget as settled. An asking price or advertised rent alone cannot tell you the ongoing cost.
For Perth, make expected family visits and overseas travel part of the same comparison as housing and transport. For Adelaide, record summer energy needs, your likely car use and any interstate commitments. In each case the relevant question is what your own location and routine cost, not a claim that the city is universally cheap or expensive.
Hobart, Canberra, Darwin and regional locations
For Hobart, include heating, the condition and efficiency of the home and the flights you expect to take. For Canberra, check rates, heating and transport; a defined-benefit super arrangement may also require a different retirement model from the accumulation calculator on this site.
For Darwin, obtain local cooling, insurance and maintenance estimates and consider the seasonality of travel. In regional or rural areas, budget for vehicle replacement, fuel, specialist healthcare journeys, property upkeep and visits to family. Lower housing costs should be assessed alongside these other commitments.
A repeatable way to compare two locations
Create one column per location and record the source and date beside each amount. Include annual rent or owner costs, utilities, food, transport, health, leisure, family visits and holidays. Put buying, selling and moving expenses in a separate one-off row. Keep the home type and household size consistent.
Enter each completed budget into the same age guide, holding the balance, salary, returns and retirement date fixed. The difference in the calculated capital then reflects your entered costs. The city selector on our planner changes the checklist only; it never changes the numbers without you changing a field.
Finally test the items with the least certainty, such as future rent, insurance or a car replacement. Before moving, visit the area and investigate the services you rely on. The financial model can compare a budget, but it cannot put a reliable dollar value on proximity to family, community or healthcare.
Your two-location comparison worksheet
Download the editable location budget worksheet (CSV) and open it in Excel, Numbers or Google Sheets. Enter annual amounts, write the location and property type, and record where each estimate came from. Separate recurring costs from one-off moving and purchase costs.
| Cost | Annual calculation | Where to check |
|---|---|---|
| Rent or owner costs | Weekly rent × 52, or rates + strata + insurance + maintenance | Local listings, lease, council and property-specific quotes |
| Transport | Fuel + registration + insurance + fares + replacement allowance | Your travel pattern and current local fares |
| Living, health and utilities | Monthly recurring bills × 12 + irregular costs | Actual bills and quotes for the intended home |
| Family visits and holidays | Whole-household trip cost × annual frequency | Current trip and insurance quotes |
| One-off relocation | Keep separate from annual spending | Buying, selling, moving and setup quotes |
