Why monthly rent is not weekly × 4

Four weeks is 28 days. A typical month is closer to 30.4 days. If you budget weekly rent times four, you are planning for 48 weeks of rent and will be short four weeks by the end of the year.

The conversion used on Australian leases is annualised: multiply weekly rent by 52, then divide by 12. $700 a week is $36,400 a year and $3,033.33 a month — not $2,800.
