Capital Growth Calculator for Australian Property Investors
See how much an Australian property could be worth down the track. Enter the current value, an annual growth rate and how many years you plan to hold, and this free calculator compounds the growth year by year so you can see the projected value and total gain.
Capital growth is the engine behind most long-term property wealth in Australia. You can model one property or add several to compare them side by side and see how your whole portfolio might grow.

- 1
Enter the current property value
Use the price you paid or a recent appraisal. This is the starting point the calculator grows from each year.
- 2
Set an annual growth rate
Enter a yearly capital growth rate as a percentage. A long-run figure of 4% to 7% is a common assumption for established Australian markets, but past growth is no guarantee of future growth.
- 3
Choose your holding period
Pick how many years you plan to hold the property. Property is a long game, so most investors model 10 years or more to let compounding do its work.
- 4
Add more properties to compare
Use Add Property to line up several properties or scenarios. The calculator charts each one and totals them into a single portfolio view.
- 5
Read the projected value and gain
The summary shows the value at the end of each year, the growth added that year, and the cumulative gain in dollars and as a percentage.
A worked Australian example
Say you buy an investment property today for $600,000 and assume it grows at 6% per year. Here is how the calculator projects it over a 10 year hold, compounding the growth each year.
- Starting value (today)
- $600,000
- Growth in year 1 (6% of $600,000)
- +$36,000
- Value after year 5
- $802,935
- Value after year 10
- $1,074,509
- Total capital growth over 10 years
- +$474,509
- Projected value after 10 years
- $1,074,509 (up 79.1%)
At a steady 6% per year, the property grows by $36,000 in the first year, reaches about $802,935 after five years, and lands at roughly $1,074,509 after ten. That is a total capital gain of about $474,509, or 79.1% on the original value. Notice the yearly growth gets bigger over time: that is compounding, because each year's growth is calculated on a larger value. These figures are projections based on a constant growth rate, and real markets rise and fall year to year, so treat them as a planning guide rather than a forecast.
What is capital growth?
Capital growth, sometimes called capital appreciation, is the increase in a property's value over time. If you buy for $600,000 and it is later worth $1,074,509, your capital growth is $474,509. It is the gain on the asset itself, separate from the rent the property earns.
For most Australian investors, capital growth is where the bulk of long-term wealth comes from. Rental income helps cover the holding costs, but it is the growth in the property's value that builds equity you can use later. That growth is only realised in cash when you sell or borrow against it.
How compound growth is calculated
This calculator compounds growth annually. Each year it multiplies the previous value by one plus the growth rate, so a property starting at $600,000 at 6% is worth $636,000 after year one, then $674,160 after year two, and so on. The gain in each year is larger than the last because it is calculated on a bigger base.
That compounding is why holding period matters so much. At 6% a year a property roughly doubles in value in around 12 years. Small changes in the growth rate also make a big difference over a decade, which is why it is worth modelling a few different rates rather than relying on a single optimistic number.
What growth rate should you use?
There is no single correct rate, and nobody can tell you what a property will actually do. Long-run capital growth for established Australian housing has often sat in the mid-single digits per year, but it varies enormously by location, property type and the period you measure, and growth is rarely smooth from one year to the next.
A sensible approach is to run a conservative rate, a middle rate and an optimistic rate, then plan around the conservative one. Capital growth and rental yield also tend to pull in opposite directions, so a high growth area often comes with a lower rental yield. It is worth weighing both rather than chasing growth alone.
Capital growth, tax and your final return
Projected growth is a gross figure. When you eventually sell an investment property, the gain is generally subject to capital gains tax, and Australian residents who have held the asset for more than 12 months usually qualify for a 50% CGT discount on the gain. The tax that applies depends on your circumstances and the rules at the time.
Many investors also accept a cash shortfall each year, a negatively geared position, in the expectation that capital growth will more than make up for it. Whether that pays off depends on the growth actually arriving. As always, this calculator gives estimates only, and you should confirm your tax position with a registered tax agent or the ATO.
Frequently asked questions
How do you calculate capital growth on a property?
Capital growth is the increase in value over time. For a single year it is the new value minus the old value. Over multiple years the growth compounds, so each year builds on the last. A $600,000 property growing at 6% per year reaches about $1,074,509 after 10 years, a gain of $474,509.
What is a good capital growth rate for Australian property?
There is no guaranteed rate. Long-run growth for established Australian housing has often sat in the mid-single digits per year, but it varies a lot by location, property type and time period, and growth is uneven year to year. Model a conservative, middle and optimistic rate rather than relying on one figure.
How long does it take for a property to double in value?
It depends entirely on the growth rate. At a steady 6% per year a property roughly doubles in around 12 years, and at 7% in around 10 years. These are projections based on a constant rate, and real markets do not grow in a straight line, so use them as a guide only.
What is the difference between capital growth and rental yield?
Capital growth is the rise in the property's value over time, while rental yield is the annual rent expressed as a percentage of the property's value. Growth builds your equity, yield covers your holding costs. High growth areas often have lower yields, so most investors weigh both.
Do you pay tax on capital growth?
You generally do not pay tax on growth while you hold the property, only when you sell. The gain is then subject to capital gains tax. Australian residents who have held the asset for more than 12 months usually get a 50% CGT discount, but the rules and rates can change, so confirm with the ATO or a registered tax agent.
Can I use this calculator for more than one property?
Yes. Use Add Property to model several properties or different growth scenarios at once. The calculator charts each one and combines them into a total portfolio view, so you can see your projected value and overall gain across everything you own.
