The investment in the first month is 933,300 yuan, and the annual interest is 93.33 * 6% * 65438+February/65438+February;
The investment in the second month is 933,300 yuan, and the annual interest is 93.33*6%* 1 1 month/65438+February; I am an analogy.
Finally, it is the result of adding all the interest for 12 months.
Interest during construction period:
First year:1000 *1/2 * 6% = 300,000 yuan;
Second year: (1000+30)+500 *1/2 * 6% =1280 * 6% = 768,000 yuan;
Third year: (1030+500+76.8)+500 *1/2 =1856.8 * 6% =1.41.
The fourth year: (1606.8+500+11.41)+500 *1/2 = 2468.5438+0 * 6% = 65438.
Interest during the construction period: 30+76.8+11.41+148.09 = 3.663 million yuan.
The above calculation only applies to: interest is not repaid during the construction period (so compound interest must be calculated), and bank interest is settled once a year.
