Capital growth is where most long-term property wealth is built. Understanding how it's calculated — and what actually drives it — is the difference between hoping a property grows and choosing one that should.
What is capital growth?
Capital growth (or capital appreciation) is the increase in a property's value over time. It's separate from rental yield — yield is the income the property earns each year, while capital growth is the gain in the asset's value. Most investors aim for a blend of both.
Capital growth vs equity
They're related but not the same. Capital growth is the rise in the property's market value. Equity is the share you actually own — the current market value minus your outstanding mortgage. Growth lifts your equity; so do your repayments.
How to calculate capital growth
Example 1: You buy for $400,000 and it's now worth $450,000. Capital growth = [($450,000 − $400,000) ÷ $400,000] × 100 = 12.5%.
Example 2 (over time): An apartment bought for $500,000 is worth $700,000 five years later. Growth = [($700,000 − $500,000) ÷ $500,000] × 100 = 40% over five years. (A simplified figure — it doesn't account for costs, taxes or market swings.)
What drives capital growth
- Supply and demand — scarcity and population/demographic shifts in an area.
- Local development — new transport, schools, parks and commercial centres.
- The property itself — renovations and improvements, or buying below market value.
Don't forget yield, costs and tax
Total return blends capital growth with rental yield. Against that, weigh holding costs — rates, insurance, maintenance, strata, management and conveyancing — and remember not all are tax-deductible. When you sell an investment property, capital gains tax applies to the profit, and how much depends on how long you've held it and your circumstances. It's worth modelling the after-tax position, not just the headline growth.

How do you calculate capital growth on a property?
Subtract the purchase price from the current value, divide by the purchase price, and multiply by 100. A property bought for $400,000 now worth $450,000 has grown 12.5%.
What is the difference between capital growth and equity?
Capital growth is the rise in the property's market value over time. Equity is the portion you own outright — the current market value minus your remaining mortgage.
What drives property capital growth?
Mainly supply and demand and demographics in the area, local development and infrastructure, and the property itself — renovations or buying below market value.
