A PPF (Public Provident Fund) calculator is a helpful online tool that enables users to estimate the maturity amount and returns on their PPF investments based on yearly deposits, interest rate, and investment tenure. By quickly computing the total invested amount, total interest earned, and the maturity value, the calculator simplifies long-term financial planning and helps individuals make informed decisions about saving for their future goals. Using a PPF calculator also saves time and reduces manual calculation errors, providing clear insights into the benefits of systematic investing in a safe, tax-efficient scheme.
