A recurring deposit (RD) calculator is a practical financial tool that helps users estimate the maturity amount and interest earned on their recurring deposit investments. By entering the monthly deposit amount, interest rate, and investment duration, individuals can receive instant calculations of their total savings and expected returns. This makes financial planning easier, enabling users to set realistic savings goals and compare different deposit schemes efficiently. The calculator also minimizes manual errors, offering a clear view of the growth potential of disciplined, regular investments.
