Compound Growth Calculator
Compound a starting value forward at a rate you choose. This is arithmetic, not a forecast and not a property valuation — and Virtual Buyers Agent supplies no growth rate.

-20%–20%. Both ends are limits on what this box accepts, not a range Virtual Buyers Agent expects. Negative rates are enterable because markets produce them.
Yours to choose. We do not supply one, not even as an example — and a negative rate is a real option, because markets produce them.

How this works
This is compound arithmetic on a rate you choose. It shows what a number becomes if it grows at that rate for that many years. It is not a forecast, a valuation, or an opinion about any property or any market.

Inputs, assumptions and limits14 points, shown in full
Inputs used
- Starting value: $600,000
- Annual growth rate (yours): —
- Number of years: 10
Assumptions
- The growth rate is a number you typed. Virtual Buyers Agent does not supply one, does not suggest one, and has not filled one in for you.
- The rate is applied identically every year. Real property prices do not move in a straight line, and no market has ever delivered a constant annual rate.
- Compounding is annual: value × (1 + rate) raised to the number of years.
Limits of this result
- Not a property valuation and not a prediction. Nothing here is evidence that any property will be worth any of these amounts.
- No market data of any kind is used. This page does not know the property, the suburb, the state, or the year.
- Ignores every cost of holding and selling — interest, duty, rates, maintenance, agent fees, capital gains tax — and ignores inflation, so the later figures are not comparable to today’s money.
- A figure shown as — could not be calculated from what you entered. It is not zero.
Where the numbers come from
- Your entries — Live — The rate is yours. There is no VBA growth assumption on this page.
- Compound growth formula — value × (1 + rate) ^ years
Check before acting
- Compare several rates, including a negative one. Australian markets have delivered flat and falling years.
- Check what actually happened to prices in the specific suburb over the period you care about, from the state valuer-general or a licensed data provider.
What this page does
One calculation: starting value × (1 + rate) raised to the number of years. It answers "if this number grew at that rate every year, what would it be?" — nothing more.
The rate is yours. There is no default and no suggestion, so nothing appears until you enter one. That is the point: a growth rate supplied by Virtual Buyers Agent would be a claim about a property market that we cannot source and are not licensed to make.
What it is not
It is not a valuation and not a prediction. This page does not know the property, the suburb, the state or the year, and no figure it prints is evidence that any property will be worth any amount.
The earlier version of this page also showed "conservative" and "optimistic" scenarios at the entered rate plus or minus two percentage points. Both the two points and the two labels were ours, and presenting them as a range implied a confidence interval that did not exist. They are gone. To see a different rate, enter a different rate — including a negative one.
It ignores inflation and every cost of holding and selling: interest, duty, rates, maintenance, agent fees and capital gains tax. A figure ten years out is not comparable to today’s money and is not what you would walk away with.
Where to find what prices actually did
Past movement is a fact you can check. State valuer-general offices publish sales data, and licensed data providers publish suburb-level series. Ask for the series for the specific suburb and property type over the period you care about, and look at what happened in the bad years as well as the good ones.
What happened before is not a rate for what happens next, and no calculator can convert one into the other.
