Capital Growth Calculator
This is your own assumption, not a guaranteed or predicted rate — property values can also fall.
Projected future value
$1,058,782
Total capital growth
$408,782
Total growth over period
62.9%
Assuming 5.0% growth every year, a $650,000 property would be worth $1,058,782 after 10 years — a projection based only on the rate you've entered, not a forecast of what will actually happen.
Quick answer
This calculator projects a property's future value by compounding an annual growth rate you choose over a set number of years. The rate is your own assumption, not a prediction — Australian property growth varies enormously by suburb, state and market cycle, so treat the result as one scenario, not a guaranteed outcome.

Capital growth is simply the increase in a property’s market value over time. The maths behind this calculator is identical to compound interest — the same formula used for a savings balance — just applied to a property’s value instead of a bank balance:
Future value = Current value × (1 + annual growth rate)^yearsGrowth compounds: each year’s increase is calculated on the previous year’s value, not on the original purchase price. That’s why the dollar amount of growth gets larger in later years even though the percentage rate stays the same.
The growth rate is entirely your own assumption — this calculator does not predict or guarantee anything. Property markets are not predictable, and no calculator can tell you what a specific property will actually be worth in 10 years. Long-run national averages get quoted often, but real outcomes vary enormously by suburb, capital city versus regional area, and which part of the market cycle you’re measuring from — some areas have delivered double-digit annual growth for a decade, others have gone sideways or fallen over the same period. Enter whatever rate you want to test, including a low or negative one, and treat every result as “what happens if this rate holds,” not a forecast of what will happen.
Worked example
An investor owns an apartment in Geelong, Victoria, currently valued at $650,000. They want to project its value assuming 5% annual growth — a commonly quoted long-run average, though not a promise for this specific property.
Using the formula:
Future value = $650,000 × (1.05)^years
After year 1, the value grows to $650,000 × 1.05 = $682,500. From there, each year’s 5% applies to the new, higher value rather than the original $650,000, so growth compounds:
- Year 5: $650,000 × 1.05^5 = $650,000 × 1.276282 = $829,583
- Year 10: $650,000 × 1.05^10 = $650,000 × 1.628895 = $1,058,782
| Milestone | Years | Projected value | Total growth |
|---|---|---|---|
| Today | 0 | $650,000 | — |
| 5-year mark | 5 | $829,583 | +$179,583 (27.6%) |
| 10-year mark | 10 | $1,058,782 | +$408,782 (62.9%) |
Over the full 10 years, the assumed growth adds $408,782 to the property’s value — but this is one projection based on one assumed rate, not a guarantee. A different growth rate, or a period where values fall instead of rise, would produce a very different result.
Frequently asked questions
Is 5% a realistic property growth rate in Australia?
It depends entirely on location and time period. Some Australian suburbs have compounded well above 5% a year over a decade; others have gone sideways or fallen. National long-run averages are often quoted near this figure, but they smooth over huge regional differences. This calculator doesn't predict a rate — it only projects whatever rate you assume.
Does this calculator account for costs like maintenance, rates or agent fees?
No. It only compounds the property's assumed market value at your chosen growth rate — it doesn't subtract council rates, insurance, maintenance, loan interest or selling costs, and it doesn't add rental income. For the cost of eventually selling, see our cost of selling a house calculator.
How is capital growth different from rental yield?
Capital growth is the increase in a property's market value over time — what this calculator projects. Rental yield is the income a property earns from rent, usually shown as a percentage of its value each year. Investors typically weigh up both, since a property can be strong on one and weak on the other.
Can I enter a negative growth rate to model a market downturn?
Yes. Enter a negative number in the growth rate field to project a falling value — useful for stress-testing a purchase against a downturn rather than only the upside. Australian property values have fallen in real, and sometimes nominal, terms during past downturns, so it's worth checking both scenarios before relying on one projection.
Does the projection adjust for inflation?
No, the result is today's dollars compounded by your chosen growth rate, with no separate inflation adjustment applied. If your assumed rate already reflects nominal, inflation-included growth, as most published property price indices do, the future value shown is a nominal figure rather than an inflation-adjusted one.
How is this different from a compound interest calculator?
The maths is identical — both compound a starting amount by a fixed percentage rate each year. The difference is what's being compounded: a compound interest calculator projects a cash balance earning a stated interest rate, while this one projects a property's market value at whatever growth rate you choose to assume, which is far less certain.
