A SIP (Systematic Investment Plan) calculator is a handy financial tool that helps investors estimate the potential returns on their investments in mutual funds through regular, periodic contributions. By entering information such as the investment amount, expected rate of return, and the investment duration, a SIP calculator can provide a clear projection of the future value of your investments. This allows individuals to make informed decisions about their financial goals and the best way to achieve them through systematic investments in mutual funds, helping them plan for a more secure and prosperous financial future.
