How to Use This Rent vs. Buy Calculator
This calculator compares the true long-term cost of renting against buying, factoring in mortgage repayments, home appreciation, stamp duty, maintenance, and the opportunity cost of your down payment.
Understanding Your Results
How Long You Stay Is Everything
Transaction costs (stamp duty, legal fees, agent commission on sale) are roughly 6–8% of the property price and can’t be recovered until the home has appreciated past them.
What This Calculator Assumes
Stamp duty is estimated at ~4%. Maintenance at 1% of value per year. Rent growth at 3% annually. The opportunity cost of the down payment is calculated at 7% (long-run stock market return). Adjust the appreciation rate to reflect your specific city and current conditions.
Formula
Net Buy Cost = Upfront + Mortgage Payments + Running Costs − Future Home Value | Rent Cost = Total Rent + Opportunity Cost of Down PaymentFrequently Asked Questions
Is it always better to buy than rent in Australia?
No — it depends on how long you plan to stay, local property prices, and the rent-to-price ratio. In expensive cities like Sydney and Melbourne, buying is often much more expensive short-term. Over 10+ years, buying has historically outperformed renting for most Australians.
What is the opportunity cost of a down payment?
The money used as a down payment could instead be invested in shares or other assets. This calculator assumes a 7% annual return on that money if you rented instead — a significant ongoing cost that many rent-vs-buy comparisons ignore.
How much does stamp duty add to buying costs?
Stamp duty varies by state and purchase price. On a $650,000 property in NSW it’s approximately $25,000–$27,000. First home buyers may be fully exempt below certain thresholds. Use our dedicated Stamp Duty Calculator for exact figures by state.
What ongoing costs should I budget for as a homeowner?
Budget 1–2% of the property’s value per year for maintenance and repairs. Add council rates (~$1,500/yr), home and contents insurance (~$1,500/yr), and any strata or body corporate fees. These are often underestimated by first-time buyers.
How long do I need to stay to break even on buying?
Generally 5–7 years in most Australian capital cities, due to upfront costs like stamp duty and selling agent commissions (~2%). In high-growth markets with strong appreciation, the break-even can be shorter; in slow markets, longer.
Does renting mean I’m throwing money away?
No — this is a common myth. Rent pays for housing, just as mortgage interest and maintenance do. Renters who invest their down payment and the difference between rent and mortgage costs can build significant wealth. The best choice depends on your specific numbers.
