I. Basic formula for calculating interest The basic formula for calculating interest on savings deposits is: interest = principal × deposit period × interest rate.
II. Conversion of Interest Rate The conversion relationship among annual interest rate, monthly interest rate and daily interest rate is: annual interest rate = monthly interest rate × 12 (month) = daily interest rate ×360 (days); 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). Pay attention to the consistency with the deposit period when using interest rates.

The interest amount shall be calculated to one decimal place and rounded to one decimal place when actually paid. 3.
