Start Smart: Make Informed Decisions with REIWA’s Property Calculators
Are you thinking about buying your first home, selling your current one, or making an investment?
Whatever stage you’re at, understanding your numbers is key to making confident property decisions. From knowing your borrowing power to planning your upfront costs, the right tools can make the process clearer and far less stressful.
That’s where REIWA, the Real Estate Institute of Western Australia, comes in. For over 100 years, REIWA has been helping buyers, sellers, and investors make informed financial choices with trusted advice and easy-to-use online tools.

Check Your Numbers Before You Buy, Sell or Invest
To help you get started, I’ve pulled together a few of my favourite REIWA resources, all designed to help you understand your position and plan ahead:
- Borrowing Power Calculator – find out how much you could borrow based on your income and expenses.
- Property Buying Cost Calculator – estimate the upfront costs involved in purchasing your new home.
- Property Selling Cost Calculator – understand the potential costs involved in selling a property.
- Stamp Duty Calculator – calculate how much stamp duty you’ll need to pay in WA.
- Budget Planner Calculator – track your income, expenses, and savings goals.

Why I Love the Budget Planner
One of my favourites right now is REIWA’s Budget Planner. It’s a simple, practical way to map out where your money goes each month, set savings targets (whether that’s for a deposit, renovation, or investment), and keep your financial goals on track.
