what is the best investment plan other than share market

Investing in equity markets requires careful research, active management and an adequately diversified / balanced portfolio. Since you are young and have already lost money by directly investing in equities, it is suggested that you invest in diversified equity mutual funds or balanced funds. Since you can invest 25,000 per month, opting for a systematic investment plan (SIP) will be the best way to build a great corpus and also help you against high or low phases of the market and mitigate risk.

You can accumulate Rs. 60,918,406 (assuming 12% annualised SIP returns) on an investment of Rs. 25,000 per month over 27 years (your current age – your retirement age)
