Rent Reduction Calculator

Published on 11/05/2020

We are proud to make this calculator available to people in NSW looking at negotiating rents. It's an unfamiliar process for many people, and it can be tricky working out what you can afford to agree to or what offer you should make!

The calculator lets you put in a range of information about your rent and income situation and then allows you to check what different scenarios of reduction including waiver of rent or deferral look like for you. It is important that you consider your ability to meet the arrangement both in the short term and later when you are paying back any deferred amount. It also contains reminders to consider potential financial hardship in agreements that do not leave you enough to cover amounts left over after rent that is required to be able to ensure enough food, utilities and other essentials for a healthy life.

You can seek tenancy advice from your local Tenants' Advice and Advocacy Service on this site or for financial advice speak to a Financial Counsellor.
