If you deposit 4,000 yuan for three months, how much interest can you get?

Interest calculation formula: principal multiplied by annual interest rate multiplied by deposit term, or principal multiplied by monthly interest rate multiplied by deposit months.

Three-month interest on a deposit of 4,000 yuan (calculated at the annual interest rate of 3%):

4000 times 3%/ 12 times 3=30 yuan.

Plus the principal of 4000 yuan, that is to say, after 3 months, you can get the principal and interest of 4030 yuan (4000+30).
