The annual interest rate of China Construction Bank's current savings deposit is 0.35%.

1. The formula for calculating interest is; interest = principal * interest rate * term. A current deposit is calculated as 30 days in a month and 360 days in a year.

The minimum deposit amount for a current deposit is one yuan.

Interest is calculated in yuan, and interest below yuan will not be calculated.

2. For example, if you have a current deposit of 10,000 yuan in China Construction Bank, the interest rate is 0.35%, and the deposit time is one year, then the interest you get is 10,000*0.35*1=350. The principal plus interest is 10,00350=10,350.

3. Interest on personal demand deposits is settled quarterly, and the interest is calculated based on the listed demand rate on the interest settlement date.

If the account is liquidated before the interest settlement date, the current interest rate announced on the account liquidation date will be calculated until the day before the account is liquidated.

The interest settlement date for demand deposits is at the end of each quarter.

That is, the 20th of the last month of each quarter is the interest settlement date (March 20, June 20, September 20, and December 20).

The interest will be credited to your account on the 21st the next day.

On March 20, the bank will calculate the interest once, interest 1 = 10,000 (yuan) × 78 (day) × 0.35% ÷ 360 (/day) = 7.58 yuan.

During the 78 days in the first quarter, interest was calculated based on simple interest, resulting in current interest of 7.58 yuan.

Starting from March 21, the interest of 7.58 yuan will be combined with the principal of 10,000 yuan and included in the deposit balance as the principal for interest calculation in the second quarter, which means there is compound interest.
