Mr. Wang, who has worked in a law firm for three years, has a current deposit of 200 thousand in his bank account. According to the current interest, the total interest of Mr. Wang's one-year current deposit is:
200,000× 0.36% = 720 yuan
If Mr. Wang buys 200,000 yuan of space-based products, the annualized rate of return of space-based products is 1.65% (assuming that this rate of return has not changed for one year), and Mr. Wang's annual investment income is = 200,000×1.65% = 3,300.
Comparing the two, the use efficiency of Mr. Wang's fund is equivalent to the original 3300/720=4.58 times, and the accumulated extra income for one year is 3300-720=2580 yuan.
Note: The case is based on hypothetical data and does not represent the actual income of investors. The yield (annual interest rate) of each product will fluctuate slightly due to market changes.
