What is the formula for calculating bank interest rates?

The calculation formula of bank interest rate is as follows: bank interest rate = interest - (principal x time) x 100. The interest rate is the ratio of the interest amount of deposits and loans to the principal during the interest period. According to time, it is divided into three types: annual interest rate, monthly interest rate and daily interest rate.

The interest rate is the ratio of the amount of interest due on a loan, deposit, or loan to its par value each period. The interest paid on the total amount of the loan depends on the principal amount, interest rate, frequency of compounding, loan term, deposit or loan, etc. Reasonable interest rates are crucial to leveraging the economic leverage of social credit and interest rates. During a depression, lowering interest rates and expanding the money supply can stimulate the economy. In times of inflation, raising interest rates and reducing the money supply can curb the vicious growth of the economy.
