Total compound interest = principal *( 1+ annual interest rate) deposit period
In which, the principal is 200,000 (200,000), the annual interest rate is 3%(0.03), and the deposit period is 65,438+0 years. Substituting these values into the formula can calculate the total amount of compound interest. The calculation formula is as follows:
Total compound interest = 200000 * (1+0.03)1= 206000.
Therefore, according to the compound interest of 3% a year, the total amount of 200,000 deposits after one year is 206,000 yuan.
