Rent calculator Australia FAQs
Why isn't a month just 4 weeks for rent conversion?
A calendar month averages 30.44 days (365.25 ÷ 12), not exactly 4 weeks (28 days) — using a flat ×4 multiplier under-counts monthly rent by about 8%. This tool converts through the actual average days in each period so the numbers line up correctly.
Where does the "30% of income" rule come from?
It's a widely used Australian benchmark for identifying "rental stress" — spending more than 30% of household income on rent. It's a general guideline, not a hard rule, and your own comfortable amount may be higher or lower depending on your other expenses.
Do bond rules really differ this much between states?
Yes. Most states cap bonds at 4 weeks' rent, but Victoria, WA, and SA all allow a higher bond once weekly rent passes a set threshold, and the Northern Territory uses 6 weeks as its standard cap. Always confirm the current figure with your state's tenancy authority before paying or requesting a bond.
What's the difference between gross and net rental yield?
Gross yield is simply annual rent divided by property value. Net yield subtracts your annual expenses (rates, insurance, management fees, maintenance) first, giving a more realistic picture of the actual return.
How does the "split rent by room size" calculator work?
It divides the total rent in proportion to each room's floor area, so someone with a larger room pays a larger share. It's a fair starting point for a conversation, not a strict formula — housemates often adjust further for things like a private bathroom or extra storage.
