For most first home buyers, the deposit is the real barrier, not the mortgage repayments, but the years of saving it takes to get to the front door. And how long that takes depends enormously on where you’re buying. Here’s the plain-language guide to how long a deposit really takes across Australia, and the practical ways to get there sooner. [PUBLISHING NOTE: deposit-time figures are illustrative estimates based on average full-time income and current medians; label as estimates and refresh periodically. Scheme details change, verify before publishing.]
Why the Deposit Is the Hardest Part
A traditional home deposit is 20 per cent of the purchase price, the threshold at which you avoid Lenders Mortgage Insurance (LMI). On a million-dollar home, that’s $200,000 in cash, saved while also paying rent and living costs. It’s a genuinely enormous ask, and it’s why the deposit, not the repayments, is what keeps most people renting longer than they’d like.
Nationally, it now takes the average person around 11 years to save a 20 per cent deposit, and considerably longer in the most expensive cities. The chart below shows how the deposit hurdle varies by location.
Why It Takes Longer in Some Cities
The pattern follows prices. In Sydney, where the median house price is highest, saving a full 20 per cent deposit takes the longest, well over a decade for many. More affordable capitals like Perth and Melbourne (which has had weaker recent growth) sit lower, though still years of dedicated saving.
The cruel maths of a rising market makes it worse: when prices grow faster than you can save, the deposit target moves further away even as you save toward it. That’s the treadmill many first home buyers describe, running hard just to stay in place.
The Schemes That Change the Maths
Here’s the crucial part: you may not need the full 20 per cent. Government schemes have genuinely rewritten the deposit equation for eligible first home buyers.
The federal Home Guarantee Scheme lets eligible first home buyers purchase with as little as a 5 per cent deposit, with the government guaranteeing the rest, so you avoid LMI entirely. Shared-equity schemes like Help to Buy can reduce the amount you need to borrow and therefore the deposit required. These schemes can cut years off the wait, turning a decade of saving into a few years. They have eligibility rules, price caps and limits, so check the current details, but for many buyers they’re the difference between buying now and buying never.
How to Save a Deposit Faster
Beyond the schemes, several practical levers genuinely help. Automate your savings so a set amount moves to a dedicated high-interest savings account each payday before you can spend it. Use the First Home Super Saver Scheme, which lets eligible first home buyers save for a deposit inside superannuation with tax advantages. Cut your biggest expenses, not just the small ones, housing and transport move the needle far more than coffee. And consider buying somewhere more affordable, or a unit rather than a house, to lower the deposit target itself.
Combining a smaller-deposit scheme with disciplined saving is what gets most first home buyers there fastest.
Rethinking the Target
One mindset shift helps enormously: the 20 per cent deposit is a guideline, not a law. With a scheme letting you buy at 5 per cent without LMI, the question changes from “how do I save $200,000?” to “how do I save $50,000 and qualify for a scheme?” That’s a far more achievable goal, and it’s why understanding your scheme eligibility early can bring your timeline forward by years.
Just weigh the trade-off honestly: a smaller deposit means a bigger loan and higher repayments, so make sure the ongoing costs are comfortable, not just the entry.
The Bottom Line
Saving a house deposit takes years, and how long depends heavily on where you buy, from well over a decade in Sydney to fewer years in more affordable capitals. But the 20 per cent target isn’t the only path: government schemes let eligible first home buyers in with as little as 5 per cent, cutting years off the wait. Automate your saving, use the super saver scheme, understand your scheme eligibility, and the front door is closer than the daunting headline numbers suggest.
