What is capital gains tax?
A capital gain is the profit from selling an asset such as shares or mutual funds for more than you paid. Depending on the holding period, it is classified as short-term or long-term, each taxed at a different rate. Understanding this is the first step to using the Capital Gains Calculator effectively, because the quality of your result depends on the assumptions you feed in. Correctly classifying the gain and applying the right rate is essential for accurate tax planning and filing. Once you are clear on the concept, the calculator simply does the arithmetic for you — quickly, consistently and without errors.
How does the Capital Gains Calculator work?
The calculator applies a standard, well-established formula so the result is consistent and reliable. In simple terms, it works out the gain from your buy and sell values and the tax using the applicable short- or long-term rate. The core formula is:
the rate depends on the asset and holding period; the calculator applies the short-term or long-term rate you select. The tool does this instantly and re-calculates the moment you change any input, so you can test different scenarios in seconds — something that would take much longer, and be far more error-prone, on paper or in a spreadsheet.

Things to keep in mind
Capital gains rates, holding periods and exemptions differ by asset class and change with the Budget — confirm the current rules for your asset before relying on the figure. Remember that any calculator is only as good as its inputs and the assumptions built into it. Markets, interest rates, charges and tax rules change over time, so treat the output as a well-informed estimate rather than a guarantee. For decisions involving significant money or tax, confirm the current rules and consider speaking to a qualified financial adviser.
