Housing Decision Analysis
Renting comes out about $88,293.55 ahead over your 8-year stay. Renting, with the $90,000 down payment invested at 7%, grows to $154,636.76 — more than the equity buying builds after $189,756.07 of net buying cost. Cheap markets or short stays often produce this result; the flexibility of renting has real value too. The break-even horizon — the stay needed for buying to win — is the number to watch if your timeline is uncertain.
*Compares buying against renting-and-investing over your expected stay using adjustable appreciation, rent inflation and return assumptions. Purchase costs modelled at 4.5% of price (stamp duty, conveyancing, inspections) and selling costs at 2.5% (agent commission, marketing, conveyancing); actual amounts vary by state and property.

Rent or buy? In Australia the question carries more cultural weight than almost anywhere else — 'rent money is dead money' is practically folklore, and negative gearing, stamp duty and the CGT-free family home all shape the answer. But the arithmetic is genuinely two-sided. Buying converts your housing budget into an appreciating asset while fixing a large part of your cost of shelter for decades; renting keeps you flexible and hands your deposit to a diversified portfolio instead of a single leveraged asset in one suburb. The honest comparison has to price everything on both sides. Buying brings upfront costs Australian buyers underestimate — stamp duty alone can exceed four percent of the price in several states — plus ongoing ownership costs like council rates, insurance and maintenance that renters never see on a bill. Selling later takes another slice through agent commission. Renting looks cheaper week to week, but rent rises with the market forever, and the deposit you did not spend only wins if it actually gets invested rather than absorbed into lifestyle. Time is the tiebreaker: short stays punish buyers because round-trip transaction costs need years of appreciation to amortise, while long stays punish renters because compounding rent growth eventually outruns everything. This calculator runs the full ledger over your expected stay and tells you which path leaves you wealthier — and by how much.
The buying ledger starts with cash out: your deposit plus purchase costs modelled as a percentage of the price (stamp duty, conveyancing and inspections in the Australian setting). A principal-and-interest repayment services the loan across the standard thirty-year schedule; ownership costs run alongside every month. At the end of your stay the home is grown at your appreciation rate, sold with agent and conveyancing costs deducted, and the remaining loan balance paid out. Everything left after recovering those proceeds counts against the buy side. The renting ledger tracks rent inflated annually at a fixed growth rate for every year of the stay, then credits the alternative: your would-be deposit invested at your expected return, compounding untouched. Net cost on each path is total outgoings minus whatever value survives the period, and the calculator reports the difference between them. Three assumptions do most of the work, so test them deliberately: appreciation versus investment return sets which asset compounds faster; rent inflation quietly punishes long tenancies at three percent a year; and the stay length spreads or concentrates the heavy transaction costs. A two-percent-of-price margin either way is inside the noise of those inputs — treat near-tie results as lifestyle calls, not financial ones.
Round-trip transaction costs — duty, legal work, inspections going in; commission and marketing going out — can swallow seven percent of an average capital-city property. On a short stay, appreciation must first repay that toll before ownership beats even a mediocre renting outcome. This is why the honest rule is: buy when you expect to stay roughly five years or more, rent when you might move for work, family or simply want optionality. The calculator's break-even behaviour around short horizons is not a quirk — it is the toll showing up in the numbers.
Australia uniquely exempts the family home from capital gains tax. Every percentage point of growth on an owner-occupied house is tax-free wealth, whereas the rented-path portfolio pays CGT on gains when realised, and dividends along the way are taxable too. That asymmetry means a home needs a lower pre-tax return than shares to deliver the same after-tax outcome, and it is a genuine reason the 'buy' column wins more often here than in countries without the exemption. Model it honestly rather than dismissing home ownership as emotionally expensive.
For the first decade of a thirty-year loan, most of each repayment is interest — also money gone — and owners simultaneously wear rates, insurance, body corporate and maintenance that renters never pay. The renter's equivalent 'dead money' ends when they stop paying rent; the owner's continues for thirty years but is offset by an asset growing underneath. Neither slogan survives contact with the actual ledger. What matters is the spread between what housing costs on each path and what the freed-up dollars earn elsewhere — which is precisely what this page computes.
Be brutally realistic about how long you will hold the property. Career mobility, kids' schooling and relationship changes move people far more often than five-year plans admit. Enter both a conservative and an optimistic stay length and see whether the verdict flips — if buying only wins on the hopeful scenario, renting is the safer financial choice until your life settles.
The renting path only wins if the deposit-equivalent actually compounds somewhere productive. Automate transfers into a diversified portfolio or high-interest structure the month you decide to keep renting; otherwise the comparison flatters renting with money that will really be spent. The difference between modelling discipline and practising it is the single biggest gap between this calculator's answer and people's lived outcomes.
Before deciding, collect real numbers: your council's rate notices for comparable suburbs, insurance quotes for the actual dwelling type, strata levies if considering an apartment — older buildings can carry levies that rival a second mortgage — and a maintenance allowance of roughly one percent of the property value per year. Entering an honest monthly ownership figure changes results materially and prevents the classic post-purchase surprise of an affordable mortgage wrapped in unaffordable running costs.
Jess was approved for an inner-city apartment purchase in Melbourne when a promotion offered her a transfer to Brisbane within eighteen months, then possibly Perth after that. Running her realistic three-to-four-year horizon showed buying losing to rent-and-invest by tens of thousands once stamp duty and selling costs were counted twice. She kept renting at $560 a week, automated her deposit into an index portfolio, and moved cities twice with one phone call each time. Five years on, her invested deposit had grown faster than the apartment's equity would have.
The Nguyens settled in Western Sydney knowing they were done moving — schools, family and work were all locked in. Their $750,000 purchase carried about $33,000 in transfer duty up front, but over twelve years the combination of appreciation at three and a half percent, principal repayment and zero rent increases swamped the renting alternative by well over $150,000. Their case is the textbook long-horizon result: transaction costs amortised into irrelevance, compounding doing the rest.
Tom bought a $620,000 inner-Brisbane unit planning to hold five years but sold after three when his partner's career relocated interstate. Between duty, legal fees and a soft market for apartments, his round-trip transaction costs exceeded $45,000, and modest unit growth had not covered them. Renting the identical unit would have cost less overall even before counting his forgone investment returns. Tom's takeaway was not 'never buy' — it was that his horizon, not the market, decided the result.
