There are various avenues for investment ranging from risk - less to high - risk.One of the important avenues for investment is Public Provident Fund. A provident fund (PF) is basically a plan to provide financial security after retirement. PPF is one of only three exempt-exempt-exempt (EEE) investment schemes available in India. Investment can be made in small amounts and end up with the big corpus by the time of retirement . PPF Scheme even though it is government backed but interest risk is always there. So thinking the same interest will get in future too may harm your financial goal. However, even today the Public Provident Fund (PPF) still proves to be a winner when compared with any of other investment products.
