The amount of interest depends on three factors: principal, deposit period and interest rate level. Principal is the original amount of a loan, deposit or investment before interest is calculated. Interest rate, also known as interest rate, is the ratio of interest to principal on a certain date, which is generally divided into annual interest rate, monthly interest rate and daily interest rate. The annual interest rate is expressed as a percentage, the monthly interest rate is expressed as one thousandth and the daily interest rate is expressed as one thousandth.
Interest rates are divided into annual interest rate, monthly interest rate and daily interest rate. The conversion relationship is: annual interest rate = monthly interest rate × 12 (month) = daily interest rate ×360 (day); Monthly interest rate = annual interest rate ÷ 12 (month) = daily interest rate ×30 (days); Daily interest rate = annual interest rate ÷360 (days) = monthly interest rate ÷30 (days). In addition, the use of interest rates should be consistent with the deposit term.

Provisions on the calculation of deposit term
1. When calculating interest, the number of days of deposit is calculated at the beginning, not at the end, that is, from the date of deposit to the day before withdrawal;
2, regardless of leap year, average year, regardless of the size of the month, 360 days a year, 30 days a month;
3. Calculated by year, month and day, the maturity date of various time deposits shall be subject to year, month and day. That is, from the deposit date to the same day of the following year is a pair of years, and the deposit date to the same day of next month is a pair of months;
