A forex compounding calculator is a critical tool to know the estimated growth of your investments over time. The calculator is available online, where you can enter the initial investment, the expected return rate, and the investment period. With that, you will know the expected return potential. However, be aware that the return can always differ because of the changes in the market scenario. So, to build the required corpus, you need to invest slightly more than what the calculator might be showing. It’s all about being focused and maintaining strict financial discipline to achieve the required forex trading profits.
