The annual interest rate is generally% (percentage), and the monthly interest rate is generally expressed as ‰ (one thousandth); The daily interest rate is expressed as a few tenths of the principal, usually called a few cents.

If the annual interest rate is 6.5%, taking the principal of 1 ten thousand yuan as an example, the annual interest is 650 yuan.

According to the formula, interest = principal * interest rate.

Substituting the data, we can get the formula:

Interest = 10000*6.5%=650 yuan.

Extended data:

With the acceleration of globalization, the domestic economy is more and more closely linked with the global economy, and the domestic interest rate level is increasingly affected by global economic growth and inflation. As can be seen from the above figure, there is an obvious negative correlation between the US dollar index and the yield of China 10 government bonds.

From the perspective of economic growth, the dollar is an important safe-haven asset. When the global economic growth rate decreases, the increase in demand for US dollars will push up the US dollar index, while the global economic shock will lead to the fluctuation of interest rates, so the domestic interest rate is negatively correlated with the US dollar index. From the perspective of inflation, the US dollar is the most important settlement currency in international trade, and the US dollar index is negatively correlated with commodity prices.

The downward trend of the US dollar index is usually accompanied by the rising prices of crude oil and other commodities, which will drive domestic inflation expectations and then raise interest rates.
