FAQ
Is it cheaper to rent or buy in Australia in 2025?
It depends on your city, property price, interest rates, and how long you plan to stay. In most capital cities, monthly mortgage repayments exceed equivalent rent in the early years. However, buying builds equity through loan repayment and property growth, while renting frees up capital to invest elsewhere.
How does the calculator compare buying and renting?
It projects two paths year-by-year on the same convention: both are valued as if you exited that year. The buying path tracks your home equity (property value minus loan balance), which is capital gains tax free under the main residence exemption, less the cost of selling — agent commission, marketing and conveyancing. The renting path assumes you invest the money you would have spent on a deposit, stamp duty, and legal fees, plus any annual savings from cheaper rent, then charges capital gains tax on that portfolio as if you sold it at the end of the holding period. In the years where rent costs more than the mortgage plus ownership costs, the surplus goes the other way — the buyer invests it, in a portfolio taxed on the same footing as the renter's.
What costs are included in the buying path?
Upfront: deposit, stamp duty (calculated by state), and $2,500 in legal fees. Ongoing: mortgage repayments (principal & interest), council rates, home insurance, maintenance, and strata fees.
What is the break-even year?
The break-even year is when buying wealth (home equity) first exceeds renting wealth (investment portfolio). Before this point, you would have been better off financially renting and investing.
Does stamp duty make a big difference?
Yes. Stamp duty is a major upfront cost that the renter avoids and can invest instead. In NSW, stamp duty on an $800,000 property is over $30,000. This amount, invested at 7% for 10 years, grows to over $59,000.
Does this calculator include capital gains tax?
Yes, on the renting path. Your main residence stays CGT-exempt, so the buying path has no CGT. The renter's investment portfolio does: the calculator assumes it is sold at the end of the holding period and taxes the gain at your marginal rate. Because the 50% CGT discount is abolished from 1 July 2027 (Acts 49 and 50 of 2026), gains are split at that date — growth up to 30 June 2027 keeps the discount, and growth after it has its cost base indexed for CPI and is taxed at the higher of your marginal rate and a 30% minimum. Leaving CGT out can reverse the answer on a 10 or 20 year horizon.
What changes for capital gains tax on 1 July 2027?
Treasury Laws Amendment (Tax Reform No. 1) Act 2026 (No. 49) and the accompanying rates Act (No. 50) abolish the general 50% CGT discount for individuals, trusts and partnerships from 1 July 2027. In its place, assets held at least 12 months get cost base indexation for CPI, and the real gain is subject to a 30% minimum tax under new Division 119. Assets held on 30 June 2027 are deemed disposed of and reacquired, so the gain accrued to that date keeps the old 50% discount and only later growth falls under the new rules. Your main residence is unaffected.

Tax Accuracy & Sources

Reviewed: March 2026 · Tax year: 2026-27

This calculator uses current stamp duty rates by state. Property growth, rent growth, and investment returns are assumptions — actual results will vary. Capital gains tax on the renter's portfolio IS modelled, assuming the whole portfolio is sold at the end of the holding period and applying the 1 July 2027 reform split (50% discount on growth to 30 June 2027; CPI cost base indexation plus a 30% minimum tax after it). Selling costs on the property ARE modelled, at a default 2.5% of the sale price for agent commission, marketing and conveyancing. It does not account for franking credits or distributions along the way, rental income tax implications, or changes in interest rates over the holding period.
