Mutual Fund SIP Calculator, also known as a Systematic Investment Plan (SIP) Calculator, is an online tool that helps investors estimate the future value of their mutual fund investments made through regular SIPs. By entering details such as the monthly investment amount, investment duration, and expected annual return rate, users can calculate the total investment amount, estimated returns, and the final maturity value. This tool is useful for planning long-term financial goals like retirement, education, or buying a house.
