Property Equity Calculator & Forecast
Forecast property value, loan balance and investment property equity over time.
See how much equity you could build over the next 5, 10 or 20 years.
Your property
What you pay for the property today.
Your cash in. The rest becomes your starting loan.
Starting loan ≈ A$600,000, starting equity ≈ A$150,000.
Long-term average price growth you're assuming. Growth is never guaranteed.
Repayments chip away at the loan, so equity grows from paydown as well as price.
Equity over 15 years
The teal band is your equity — it widens as the property value (top of the chart) rises and the loan (grey) is paid down.
Equity in 15 years
A$1,132,903
Up from A$150,000 today — a gain of A$982,903.
Projected value
A$1,559,196
With about A$426,293 still owing on the loan.

A simplified projection based on a constant growth rate and your loan terms. Real property prices rise and fall year to year — this shows the long-term shape, not a guarantee.
How equity builds over time
Equity is the slice of the property you actually own — its value minus what you still owe. Over the long term it grows from two directions at once.
Value growth
Property value − starting value
If a property grows in value over time, that increase belongs to you, not the bank. A property that rises from $750k to $1.2m over 15 years has added $450k of equity through growth alone — even before you've paid a cent off the loan.
Loan paydown
Starting loan − remaining loan
With a principal & interest loan, each repayment shrinks the balance you owe, so more of the property becomes yours every month. On an interest-only loan the balance stays flat, and equity grows from value alone.
Equity = value − loan
In the chart above, the top of the stacked area is the projected property value. The grey band is what you still owe, and the teal band is your equity. As the years pass the value line climbs and the loan band narrows, so the teal equity band widens — that widening gap is the wealth the property is building for you.
Why the growth rate matters so much
Growth compounds, so small changes in the annual rate make a big difference over 10 to 20 years. That's also why this is an estimate: real property values rise and fall from year to year, and no one can promise a steady rate. Try a few conservative and optimistic figures to see the range of outcomes rather than banking on a single number.
