About this calculator

Your equity grows in two ways: the loan balance falls as you repay it, and the property value may rise or fall. This calculator projects both, year by year, so you can see how your equity could change.

Enter your property value, loan, interest rate, years left and an assumed growth rate. Add extra repayments to see how much sooner you could be loan-free.

Use it to compare scenarios. Set growth to 0% to see the equity you build from repayments alone, then try a higher rate to see how much price growth could add. Extra repayments show the effect of paying the loan down faster, and the usable equity column shows how much you could borrow against the property each year.

How it works

Frequently asked questions

How does home equity grow?

Equity grows when you repay loan principal and when the property value rises. If values fall, equity can shrink even while you repay the loan.

What growth rate should I use?

Nobody can know future property growth. Try several rates, including 0%, to see how much of your equity comes from repaying the loan rather than from price growth.

Do extra repayments increase equity faster?

Yes. Extra repayments reduce the loan balance sooner, which raises equity and cuts the interest you pay.

What does the calculator leave out?

Selling costs, taxes, redraws, further borrowing, renovations and changes in interest rates. It is general information, not financial advice.
