Monthly Rent Calculator: How To Calculate Monthly Rent

Svetlana Nikolic By Svetlana Nikolic March 12th

Congratulations, you’ve managed to find the perfect home for rent, which is nothing but great news!

However, before you put down a security deposit on your dream rental property, it’s essential first to understand its affordability and rent amount. 
If you’re a first-time renter, you may be left feeling confused about how your monthly rent is calculated. You might be happy to learn; that you’re not alone! It’s one of the most commonly asked questions by first-time Australian renters. 

There is no formula in the legislation on how to calculate rent in Australia, and Property Managers use several different formulas, including Leasing Consultants, Landlords, and Renters- all yielding the same (and correct) rental amount. 

You will need to determine the monthly rental amount to budget and accurately set aside your income for rent (be sure to take into account the rent between household members while you’re at it). A slight miscalculation can have a significant impact on your monthly rent repayments, and you certainly don’t want to fall in arrears or apply for a property you can’t afford (a renter’s nightmare).

To assess the affordability of the leased property, you must understand how rent is calculated in the rental market before the ‘For Rent’ sign is taken down and you sign the tenancy agreement.

This article hopes to explain how monthly rent is calculated and provide you with a quick and easy-to-use rent calculator formula to help prepare your (correct) budget in time for your move.

How is monthly rent calculated?

Rent is typically quoted per the weekly rate, and payments are made per calendar month. The most common mistake people make is to assume that there are 4 weeks in a month. As you may have already discovered, multiplying your weekly rental payments by 4 does not equal the monthly rent vs weekly rent owed.

Why? The answer is simple, not every month has an equal number of days. This means that calculating your monthly rent is not as straightforward as multiplying the weekly rent by 4 or the fortnightly rent by 2 (and don’t forget leap years).

To calculate your monthly rent repayment, use this simple formula to convert weekly rent into the monthly rent payment. 

  • Step 1: Weekly Rent ÷ 7 = Daily Rent amount 
  • Step 2: Daily Rent x 365 = Yearly Rent amount 
  • Step 3: Yearly Rent ÷ 12 = Monthly rent amount 

For example, if the rent is quoted as being $400 per week, we would plug 400 into the formula to get the monthly rent amount (step 3) below.

  • Step 1: 400 ÷ 7 = 57.14
  • Step 2: 42.85 x 365 = 20,856
  • Step 3: 20,856 ÷ 12 = 1,738

If the weekly rent rate is $400, the monthly rent repayment will total $1,738.
