It is entirely possible that the fixed investment fund market will improve for a long time. The average annual income is around 10-20. It is deposited in 500 yuan for fixed investment every month, with a 30-year investment of 6,543,800 yuan+0.8 million yuan. According to the annual rate of return 10%, after 30 years, your total capital will be 1085660 yuan, less investment 1800 yuan, which should be more than 900,000 yuan. Calculated according to the rate of return 15%, it will be 299,9741yuan after 30 years, and the profit will be about 2.8 million yuan after deducting the investment180,000 yuan. Of course, there is great uncertainty in these 30 years, but if the China stock market will be mature and sound in these 30 years, I believe there should be a high return on investment.
