January 2026 8 min read

A Property and Capital Gains Tax (CGT) calculator will enable you to calculate the amount of tax payable upon selling a property or shares. Rather than making assumptions about how much tax you actually owe, this tool provides quick, accurate calculations, considering exemptions, reliefs, and applicable rates.

Property & Capital Gains Tax Calculator Concept

It is useful for homeowners, property investors, stock traders, or individuals selling assets that are charged capital gains tax. Using a calculator will help you account for taxes in advance and avoid surprises when filing returns.

โ“ What Is a Property & Capital Gains Tax Calculator?

Property and CGT Calculator

With the help of the property and CGT calculator, one can calculate the tax due on profits gained through the sale of assets. In the case of property, the gains are calculated by taking the difference between the sale and purchase price, taking into account certain allowable expenses, such as improvements and exemptions.

Concerning other assets, such as stocks or an investment, taxes like capital gains tax or investment income tax, or the selling price, are considered.

The resulting statement shows tax payable and net profit after tax. Thus, financial planning can be carried out easily.

Step 3: Apply Tax Rate

Apply the applicable capital gains tax rate, which can vary based on income level, property type, and holding period.

Step 4: Calculate Net Profit

Net Profit = Gain โ€“ Tax Payable
