As per Wikipedia, the Public Provident Fund (PPF) is a savings-cum-tax-saving instrument in India introduced by the National Savings Institute of the Ministry of Finance in 1968. PPF allows you to save small sums of money, and offers a guaranteed interest rate and tax benefits that make it attractive for many conservative investors. PPF is a fantastic debt instrument which has guaranteed return (though it has fallen over time) but it is still higher than the market rate in other options. Since there is a 15 years lock-in (which can be extended in blocks of 5 years) and to keep the account active you need only ₹500/year, open it and keep it active. Later when you need to invest more amount in long-term debt investments, both the maturity of PPF will be closer and you will have many options like debt mutual funds. You can open PPF in your own name plus in the name of your parents if they don’t have one already. When you get married and have children, you repeat this for your spouse and children. PPF is an EEE-class instrument which means that it is exempt from tax on investment up to 1.5 lakhs/year under 80C, exempt from taxation during growth and there is a full exemption on taxes at maturity.
