Using the m.Stock SIP calculator is easy and intuitive. Start by visiting the m.Stock website and locating the SIP calculator tool. Enter the amount you wish to invest periodically, such as monthly. Then, input the expected annual rate of return based on your investment choices. Specify the investment duration, indicating how long you plan to continue your SIPs. The calculator will then provide an estimate of the future value of your investments, helping you understand potential returns and plan your financial goals more effectively.
