How much rent is too much? The 30% rule in practice

The 30% rule is simple: spend no more than 30% of your gross income on rent. For decades, it's been the gold standard for housing affordability. But in 2026 Melbourne, it's becoming a luxury many renters simply can't afford.

Consider a practical example. A couple earning a combined $120,000 annually should, by the rule, spend no more than $3,000 per month on rent. In inner suburbs like Fitzroy or Carlton North, a two-bedroom apartment now easily commands $2,400–$2,800. Add parking, utilities, and insurance, and they're already at the limit before groceries or transport.

Move further out to Frankston or the growing Bayside suburbs, and the story shifts slightly. A two-bedroom in Mentone might rent for $1,900–$2,200, pulling families back toward the 30% threshold. Yet migration demand and the Frankston corridor's popularity are pushing prices upward faster than wage growth.

Real estate agents report tenants routinely breaching 35–40% of income toward rent. Single renters are worst hit. Someone earning $60,000 annually faces a brutal squeeze: a modest one-bedroom in Collingwood or South Yarra ($1,600–$1,800) represents 32–36% of gross income before tax.

The rule's weakness is clear: it assumes stable employment and no competing financial pressures. A renter paying 32% on rent has little buffer for car repairs, medical costs, or saving for a home deposit—the very goal that makes renting temporary rather than permanent.

Melbourne's median unit price hovering near $620,000 means first-home buyers need substantial savings or parental help. Paying above-30% rent makes that deposit feel impossibly distant. Many younger renters in Footscray, Sunshine, or Preston are caught in a trap: priced out of ownership, squeezed by rental costs, unable to build equity.

Financial advisors increasingly acknowledge the rule's limitations in high-demand markets. Some suggest 25% is more realistic for genuine financial health, especially for those saving simultaneously. Others argue location matters more than the percentage—paying 35% in affordable, transport-connected suburbs like Coburg or Northcote might offer better long-term prospects than 28% in increasingly expensive outer areas.

The Melbourne rental market's tightness means the 30% rule remains aspirational rather than achievable for many. The real question isn't whether the rule applies—it's whether renters can afford to follow it, and what happens when they can't.
