Find Out How Much You Can Invest Based On Your Income & Equity
When you’re planning your next property purchase, the first question is simple - how much can you actually afford to invest?
But the answer isn’t always obvious. Income, equity, bank lending rules, and deposit size all play a role.
Our property investment calculator takes the guesswork out of the equation. In less than two minutes, you’ll get a realistic estimate of your investment budget based on your personal numbers.
What This Calculator Does
This free tool works by combining:
Your income – salary, rental income, and any regular additional earnings
Your equity or deposit – what you already have to put towards your purchase
It then applies common lending criteria (like debt-to-income and loan-to-value ratios) to give you a realistic estimate of how much you might be able to invest in property.
Why This Matters for Investors
Knowing your buying power before you start house-hunting helps you:
Avoid looking at properties outside your true affordability range
Make faster, more confident decisions when opportunities arise
Use your equity strategically to expand your portfolio sooner
Understand how much leverage you can take on without overextending yourself
