Special formula for investment in PPF, will create a big fund for retirement

By investing a maximum of Rs 1.5 lakh every year in PPF, a big fund can be created in the long run. Under the formula of 15+5+5, the account can be continued for a total of 25 years by investing for the first 15 years and then with extensions of five years each. Based on the current interest rate, the estimated fund in 25 years can be around Rs 1.03 crore, although this is not a fixed amount. Compounding and tax benefits are available in PPF, but the interest rate is changed by the government from time to time. Before investing, definitely check the current rules, interest rates and tax provisions.
