Hello, the basic formula for calculating interest is: interest = principal × deposit period × interest rate; Interest rate conversion: 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 (day); 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). According to People's Republic of China (PRC) State Taxation Administration of The People's Republic of China Guoshuihan [2008] No.826, since June 9, 2008, personal income tax on savings deposit interest is temporarily exempted, so the interest tax on savings deposit interest is temporarily exempted at present.

Two, how to calculate the formula of bank loan interest.

(1) The interest rate conversion formula for RMB business is as follows

1, daily rate (0/000)= annual rate (%) 360 = monthly rate (%)

2. Monthly interest rate (%) = annual interest rate.

(two) banks can use the product interest method and the transaction interest method to calculate interest:

1. Accumulate the account balance daily according to the actual number of days, and multiply the accumulated product by the daily interest rate to calculate the interest. The interest-bearing formula is:

Interest = cumulative interest-bearing product × daily interest rate, where cumulative interest-bearing product = total daily balance.

2. Transaction-by-transaction interest calculation method calculates interest one by one according to the preset interest calculation formula: interest = principal × interest rate × loan term, with three details:

If the interest period is a whole year (month),

① Interest = principal × year (month )× year (month) interest rate

If the interest-bearing period is a whole year (month) and days, the interest-bearing formula is:

② Interest = principal × year (month) × year (month) interest rate principal × odd days × daily interest rate.

At the same time, the bank can choose to convert all interest periods into actual days (366 days per year), and each month is the actual number of days in the Gregorian calendar of the current month. The interest-bearing formula is:

③ Interest = principal × actual days × daily interest rate

These three formulas are essentially the same, but because the interest rate conversion is only 360 days a year. However, when the actual daily interest rate is calculated, the result will be slightly different if it is calculated as 365 days a year.

The decisive factors of bank loan interest are:

1, bank cost. Any economic activity must be divided into two categories: borrowing cost-interest paid in advance by borrowing funds; Additional cost-the cost of normal business.

2. Average profit rate. The profit must be less than the profit rate, and the average profit rate is the highest limit of interest.

3. Supply and demand of loan funds. If the supply exceeds the demand, the loan interest rate will inevitably fall, and vice versa. In addition, the loan interest rate must also consider price changes, securities returns and political factors.

However, some scholars believe that the upper limit of interest rate should be the marginal rate of return of funds. Compare the ratio of profit growth and loan amount after borrowing bank loans and the loan interest rate, as long as the former is not lower than the latter, enterprises can

1, compound interest: compound interest refers to the interest stipulated by some central banks. If the borrower fails to repay the interest within the time stipulated in the contract, the interest will be increased.

2. Penalty interest: If the lender fails to comply with the regulations, the penalty interest paid by the bank to the non-defaulting party according to the contract signed with the parties is called bank penalty interest.

3. loans overdue liquidated damages: the nature is the same as penalty interest, and it is a punitive measure for the defaulting party.
