I personally would go so far as to say, even if you are saving the maximum in EPF, open a PPF account in SBI and start saving. You get 8.7% interest in this year, and all income is tax-free. Capital when drawn and interest are all tax-free. Even if you do not get an IT rebate, it is a worthwhile investment. The only thing is that the investment is for 15 years.
An advantage with PPF is that the minimum contribution is Rs500 per year, and as a planned saving strategy, one can deposit some small sums of money - like tour expenses claims, etc. - round it off, and deposit it in PPF. Slowly, it will grow into a tidy sum.
Most of the other investments are taxable. For example, FD gives you, say, 9%, but after tax, it is more like 6%, which is lower than inflation itself. Before one jumps into the stock market, all these fixed-income savings must be tried out. Even ELSS is a good investment - go for 5-star rated funds.
There are varied avenues of nearly risk-free investments, so go ahead, diversify, and invest from your first salary itself. Hopefully, you can retire with a good nest egg, taking future price increases/inflation in mind.
Health cover is another area where there is a need for careful planning. Cover yourself and your family with adequate health cover as a normal routine. Sufficient insurance cover for earning members is a wise investment.
