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, which is usually called a few cents.

If the daily interest rate is 1%, that is, the principal is 1 yuan, and the daily interest rate is 0.005438+0 yuan. (1% =0.00 1 yuan, 10 cents =0.000 1 yuan)

So 1 Li is equivalent to 0. 1% interest rate.

Take the principal of 10,000 yuan as an example, according to the formula: interest = principal * interest rate.

The formula can be obtained: interest =10000 * 0.1%=10 (yuan).

definition

1. Money other than the principal of deposits and loans (different from "principal").

2. The abstract interest point refers to the value added when monetary funds are injected into the real economy and returned. In a less abstract sense, interest generally refers to the remuneration paid by the borrower (debtor) to the lender (creditor) for using the borrowed currency or capital. Also known as the symmetry of sub-fund and parent fund (principal). The calculation formula of interest is: interest = principal × interest rate × deposit period (i.e. time).

Interest is the reward that the fund owner gets for lending the fund, which comes from a part of the profits that the producer makes by using the fund to play its operational functions. Refers to the value-added amount brought by monetary funds injected and returned to the real economy. The calculation formula is: interest = principal × interest rate × deposit period × 100%.

3. Classification of bank interest

According to the different nature of banking business, it can be divided into bank interest receivable and bank interest payable.

Interest receivable refers to the remuneration that the bank obtains from the borrower by lending to the borrower; It is the price that the borrower must pay for using the funds; It is also part of the bank's profits.

Interest payable refers to the remuneration paid to depositors by banks to absorb their deposits; It is the price that banks must pay to absorb deposits, and it is also part of the cost of banks.

Factors that generate interest:

1, delayed consumption

Lenders lend money, which is equivalent to delaying the consumption of consumer goods. According to the principle of time preference, consumers will prefer current goods to future goods, so there will be positive interest rates in the free market.

2. Expected inflation

Inflation will occur in most economies, which means that a certain amount of money will buy less goods in the future than it does now. So the borrower needs to compensate the lender for the losses during this period.

3. Alternative investment

Lenders can choose to invest their money in other investments. Due to the opportunity cost, the lender lends money, which is equivalent to giving up the possible return on other investments. Borrowers need to compete with other investments for this fund.

4. Investment risk

Borrowers are at risk of bankruptcy, absconding or default at any time, and lenders need to charge extra fees to ensure that they can still get compensation under these circumstances.

5. Mobility preference

People will prefer that their funds or resources can be traded immediately at any time instead of spending time or money to get them back. Interest rate is also a kind of compensation for this.
