Supplementary information:
1 year deposit interest is 330 yuan, and one month interest is 27.5 yuan. According to the calculation formula of interest: interest = principal× annual interest rate (percentage )× deposit period or interest = principal× interest rate× time. The annualized rate is 3.3%, the principal 10000 yuan, 1 annual total interest 10000×3.3%× 1 = 330 yuan; There are 12 months in a year, so the monthly interest is10000× 3.3 %×112 = 27.5 yuan.
Extended data:
1. What is the annualized rate?
1, the annualized rate is the annualized rate of return, which is calculated by converting the current rate of return (daily rate of return, weekly rate of return, monthly rate of return) into annual rate of return. It is the theoretical rate of return, not the real rate of return that has been achieved. Calculation formula: annualized rate of return = [(investment income/principal)/investment days] * 365x100%; Annualized income = principal x annualized rate of return.
2. If you invest in a money fund, you will encounter a seven-day annualized rate of return, which is the data obtained from the annualized average income in the last seven days. The 7-day annualized rate of return of the money fund changes every day. If users want to buy money funds for financial management, it is best to choose the one with high annualized rate of return on the 7th, so that they can get good returns after investment.
Second, how to calculate the annualized rate?
The annual interest rate is: annual interest rate/principal × 100. For example,/kloc-0,000,000 is deposited in the bank, with an annual interest of 20,000. The annual interest rate is 2100×100 = 2%.
Third, the classification of interest rates.
1. According to different calculation methods, it can be divided into simple interest and compound interest.
Simple interest means that during the loan period, only the original interest is calculated, and the interest generated by the principal is not calculated separately. Compound interest means that during the loan period, in addition to calculating the interest of the original deposit, the interest generated by the principal will be included in the principal again and calculated repeatedly, commonly known as "rolling interest".
2. According to the relationship with inflation, it is divided into nominal interest rate and real interest rate.
Nominal interest rate refers to the interest rate that does not exclude inflation, that is, the interest rate indicated in the loan contract or document. The real interest rate refers to the interest rate after excluding inflation.
