Most Australian rentals are advertised and paid per week, but everyday budgeting, like a monthly salary or a bank statement, runs on a calendar month. The two don't convert cleanly, because a year has 52 weeks but only 12 months.
That means each month is worth about 4.33 weeks on average, not an even 4. If you multiply your weekly rent by 4 to estimate your monthly cost, you'll underestimate it by roughly 8%, which adds up fast over a year.
The correct formula
To convert weekly rent to a true monthly figure:
monthly rent = (weekly rent × 52) ÷ 12
To go the other way, from a monthly figure back to weekly:
weekly rent = (monthly rent × 12) ÷ 52
Fortnightly rent is simpler: it's always exactly double the weekly figure, since a fortnight is precisely two weeks with no rounding involved.
When this matters
- Comparing a rental listed per week against your monthly take-home pay or budget
- Working out your true annual rent cost, for example ahead of a lease renewal or a rent increase
- Converting between listings, since some agents and platforms quote weekly and others quote monthly or fortnightly
Just got a rent increase notice?
Don't just accept it. Find the counter-offer that still makes sense for your landlord, based on their actual cost of replacing you.

How do I convert weekly rent to monthly rent?
Multiply the weekly rent by 52, then divide by 12. For example, $550 a week is ($550 × 52) / 12 = $2,383 a month.
Why is monthly rent more than 4 times the weekly rent?
Because a year has 52 weeks but only 12 months, so each month averages about 4.33 weeks, not exactly 4.
Is fortnightly rent just double the weekly rent?
Yes, exactly double, with no rounding involved.
